Introduction

Charles Darwin turned science (and religion) up!oide down with the publication of hill research, but he has no chance of appearing in this book In 2009. while the scientific establishment celebrated 200 years slI1ce his birth, we took a less enthusiastic view of his work. His theory of evolution may have startled the world and he may helVe ~n a meticulous experimenter but, as far as we can see, all thai Darwin did to reach his conclUSIOns was merely observe, record and rig('lrously document, before piecing together the - admittedly very clever - theory for which hE' is famous. And that, quite frankly. doesn't put him in the same bracket as the rather more intrepid researchers you will find here - people like August Hildebrandt or Mark Grabiner. In order to find a strong anaesthebc that worked without knock.ing a humaJl uul, HiltldJram.1t's tutur injedt't.! tht! student's spine with cocaine. Hildebrandt asked his tutor to tickle his feet - he felt nothing. He then handed his tutor .. needle and asked him to stab him in the leg There was no pain. So Hildebrandt demanded that a knife should be plunged into his thigh. When he still smiled benignly. the tutor stubbed out a cigar on his leg. Nothing. But Hildebrandt wasn't finished. To check the anaesthetic was remaining local to his lower body, his pubic and nipple hair was ripped out. Only the nipples hurt. After SUrvlVmg hamm@rbloW!' to h.ts shins and a hearty tug at his testicles, presumably with some relief, he deemed the exJX!riment a success. An important

experiment for medical science, indeed. but a pretty bonkers way of going about it. All of which goes to show, as surely everyone would agree, that Darwin had it easy. If he'd wanted 10 find fame in this book he should al least have injected himscU with the droppings of one ofms famous finches jusl to see if il C'lIused him to grow an oddly shaped, bul strangely useful beak. Even better, he should have dressed himself up as a finch, sat among them and waited to be fed.

And 50 Cl'olbiner made it, Nev.-ton didn't. Of course, August Hildebrandt's outlandish experiment had a positive and beneficial outcome. But he remains one of the few true Sutte96 stories in this book. Plenty of science is dead-end research. We can learn as much from the experiments that fail as from the ones that succeed. Quite often research is dull and repetitive (even Darwin would have had days when he couldn't wait to break for a cup of tea). And anybody who has studied science at school will know what a serious and sometimes dull business it can be. Note: can be ...

'I1ti.s has produced no discernible benefit to society but, as we said, nobody died (surprisingly) and it's earned tum a platt in this book. The experiments of Hildebrandt, GrabineT and Pike are, in fact. a microcosm of what this book represents. Science can

1 Mad inventions, mad ideas

It may be apocryphal, but it's a stOf)' too delightful to ignore A minor researcher in the physics department attending a Princeton University party was writing in his notebook, and failed to recognise Albert Einstein, who had sat down next to

him. 'What are you writing?' asked the great physicist. 'Whenever I have a good idea., I write it down to make sure I don't forget replied tllf' researcher. 'Perhaps you'd like to try it.' Einstein shook his head sadly, and said: ' ( doubt it. 1 have only had two or three good ideas in my life.' Of course, not everybody who has an idea turns out to be an Albert Einstein, as this chapter reveals. NoneUu!lessl as Newlon's third law of motion states, 'to every action there is an equal and opposi te reaction'. Or, in other words, Einstein's genius needed its counterbalances. which - as yOIl can find out below - the likes of Louis DougJas mseemed more than happy to provide. Douglas cleverly invented an ent,:rtainmen! aid for anybody using a public convenienct'. Eat yo ur heart out Albert. Of course, Douglas's urinary invention is scientifically about as fa r from Einstein's speciaJ and general theories of relativity as it is possible to get. But while relativity may have transformed our knowledge of physics, space-time and the cosmos, it never had a chance of making it into this chapter. That's becaU5e'. in the main, the ideas 1k'Tt" are more earth-grounded .. , and more ludicrous. outlandish and in the spirit of this book, entirely bonkers.

You see, Einstein cleverly thought about light bending around galaxies, while Sean McKee, instead. thought about making ice lollies in the shape of pop star Madonna and other sex icons to encourage people to lick them. Einstein considered how time could slow down when humans travelled al high velocities. Eugene Politzer, on the other hand, decided to use a laser to bum off ius beard. So none of them were ever likely to steal Albert's clever-ness crown, but without them and their esoteric endeavours we wouldn't have this chapter, which pays homage to the archetypaJ idea of the 'mad scientist', beavering away in the lab, attempting to out-mvent Heath Robinson.

$ Dogs of stun In the 1990S, people were becoming so' litigious that even criminals were suing ii they were bitten by a guard dog. In 1997, things had reached such a state, according to Harvey Allen, WiIl.i.azn Buerke and Gary Erwin of Orange, California. that guard dogs had to be muzzled. However, as they so:succinctly pointed out, 'criminal suspects are less likely to submit to apprehension by . dog that is unable to bit(>'.

'The lead contained batteries and a loudspeaker that was preprogrammed to make a variety of ani.mal sounds, such as a dog badting or cat meowing. Owners could take walks by holdmg the leash out in front of them like a metal detector. The inventors lold purchasers that they would need 'a degree of imagination'.

Vogons, fans of The Hitchhiktr'll Guilh to the Galaxy will recall, w rote poetry so bad 1t could kill In 2(0), an experiment to create poems on the web looked set to automate the IlIwfulness of Vogan verse. David Rea of Greenwich, Connecticut, wrote a program that allowed a poem to evolve, to see if people wi.th diverse tastes in poetry could work together to create attractive verse. Rea's program started off with 1()(l(l 'poems', each comprising four lines of five randomly chosen words. People visiting the website chose betw"een two randomly selected ve~ from the population. The bad ones were killed off and the fittest those with the most positive votes - underwent further evolution. Each word within 8 verse was thought of as a poetic gent'. There W{'>fe a J>05Sible 30,000 words. and as people voted, some , genomes proved more popular than otheJ1l as they fanned semi-meaningful phrases. So the fittest verses were 'mated' to form new verses, and the offspring again put to the public vote, With more than 16,000 votes in, Rea believed poetic structure was emerging. But in evolutionary terms, the poems were still a metaphor short of a mudskipper, When this s.tory first went to press in 2(0), one poem read: 'You with life down the swords I How quieting tressed I Prince. held by po,.". / Could be honking fight treklri'1g.'

According to Politzer's plItt-nt, the power fo r the laSl?r would be generated by a fixed supply connected to a hand· held unit, which contained a tllnaU helium neon tube. This would beam laser light along thl' inside of a protective grid mesh, simila.r to that used in a conventional razor.

Vadovnik of Ljubljana University in Yugoslavia suggested using other muscles closer to the brain to initiate braking under emergency conditions. He elected to use the eyebrow muscles, because these are small and can react in 0.1 seconds if suitably trained. He mounted a pair of e.Iectrodes on a spectacle frame - these were kept in contact WIth the eyebrows by small springs. When drivers encountered an emergency situation, they were expected to blink rapidJy to send an electrical signal to the car's braking system. Professor Vadovnik believed that practised blinkers would be able to cut braking time by o.} seconds.

Researchers at the US Agricultural Research Service in Beltsville. Maryland, thought they had an answer. They had been blasting meat with water at explosive pressures. And they found their process also IciUed food-poisoning bacteria. such as E. coli, in the meat 'We think it is probably rupturing the bacterial ccU walls: said lead scientist Morse Solomon The process worked by sending a shock wave through the meal to bust the tough, chewy fibres. To create the shock wave, researchers placed a slab of meal on top of a steel plate at the bottom of a water-filled plastic garbage can. Then they detonated an explosive - equivalent 10 about a quarter of a stick of dynamite - inside the can.. The water tranmtitrod the shock wave through the meat,. bUI the unfortunate garbage can was blown to smithereens. Solomon said the shock waves penetrated the entire cut of meat. so bugs deep inside it were killed. achieving a thousand-fold reduction in bacteria levels during tests. Theprocess worked best on small, garbage can-sized batches. A larger tank didn't work as well. and the meat had to be packaged In robust rontainers so It wasn't destroyed.

i'!f; Edible mud In 1957. it was thought that mud dredged up from the bottom of Lake \r1ctoria. 20 metres down. might be hJrnoo into food for pigs and chickens. accordtng to the drrector of the East African Fisheries Research Organisation (EAFJ(O), Mr R. S. A. Beauchamp. After ShJdying the composition of the f3una and flora that are found in Lake Victoria, Beauchamp's colleagues discovered that there was not as much plankton as they had expected in the water, because of a shortage of suJphur. In lakes in temperate climates, millions of dead plankton. weeds and water animals fall to the bottom every year and when they decompose they return to the water the elements they took from It togrow. But the mud found otI the bed of Lake Victoria was very slow to decompose because of lack of oxygen. This meant thai at the bottom of the lake, locked up in layers of mud which ran to tens of metres deep, was the accumuJated richness of thousands of years' deposits. The water lying above was I infertile for lack of nutrients. EAFRO suggested that swamps could be filled up with the rich lake mud to make good land for market gardens. but Beauchamp 31so believed that, dried and powdered. the mud could become nutritious food for pigs and poultry becau....e it contained num~us valuable minerals and also considerable amounts of protein.

:11: Funerals without fuss Back in the '19505, a gentleman in Winnipeg devised a method of shrinking an aduJt human corpse to the size of a baby. He claimed that this would be an excellent way to dispose of dead bodies because it would be possible for the shrWlken corpses to be slid into underground tubes and buried without any of the fuss that goes with conventional buriaJ and without taking up too much spare His shrinking process depended on the application of high pressure to the corpse. This, he said, had the effect of squeezing all the f1uidsou l of thebody. The resultant mass of flesh could then be compressed to any desired shape inside a mould., similar to those used for moulding polythene. AJJ this was, of course, highly ingenious but it was uncertain why the inventor thought that his proposed form of burial was in any way better than the prevailing and very popular method of cremation. It might have been that he thought the new m~thod would appeill to those who were worried by the high cost oC buying plots in cemeteries and who did not wish their dead body to be incinerated. It may also have appealed to those whose beliefs suggested that at some point in the future they could expect to be physically reincarnated. Whatever the benefits, however, it

~ Vital statistic In l()fh, two inventors in the lB, Jack Crossman of California and Leonard Rommer of Chiago, claimed to have perfected a scientific system for measuring the size of female breasts with great accuracy. They were so proud of their results that they patented them. It seems that, in the past, this vital statistic had usually been estimated by eye. The Oldy scientific approach had been to immerse the breast in a container of water and to measure the volume of liquid displaced. According to the inventors, this was inaccurate because breasts tend to float. The solution was a ci.rcuhr sheet of transparent flexible plastic with a single radial cut and a series of radial calibrations. The circular sheet was folded into a cone and placed over the breast. The cone was then tightened until there was all·round contact. The calibrations gave an instant readout of the breast's volume in millimelres. .'

1'J-: Artificial tornado plan to generate electricity Most of u!> know thai tornadoes are unpredictable, unconl:tol~ lable and dangerous. But a Canadian engineer believed they (ould be the future of electricity generation. He wanted to make electricity from artificiJlI tornadoes. In :wo8, loWs Michaud, a retired petroleum engineer in Samia, Ontario, planned to use the waste heat from conven· tional power plants to create an 'abnospherk vortex engine' - a small, controlled tornado that wouJd drive turbines and generate eJectririty. 'I'm confident that we could control these things: he said. Michaud alio thought solar~powered torna· does generated using the sun's heat could work. His design was a circular wall 200 metres across. and 100 met:res high Without a roof. Alrcanying the waste heat would be blown in from vents on the sides, spinnmg around the walls into a vortex that becoml!S just Ukea real tornado. Once o;t:uted, the vortex wouJd draw in moIl.' hot air £rom vents in the wall, pulling it past turbines and generating electricity. Michaud calculated that a vortex engine of this size would create a tornado about SO mct:res in diameter and generate between 50 and 500 MW of electricity. He patented the idea in 1'n5 and has continued to work on it ever since

It was caUed the Meteotron and consisted of an array of 100 burners spaced over an area rather larger than a football field. Fuel was pumped into them and, together, they consumed about a ton of oil a minute, producing the very considerable power of SOme]OO,ooo kilowatts. In , operation the device produced a thick column of black smoke thot permitted observation!l of the resultin.g upward air currents. During one e1(periment there appeared.. besides the main mass of smoke, what seemed to be a black tube of whirling smoke.

ror years the US army had wanted to supplement its .lIIndard battlefield rations, called 'Meal, Ready~tt;Eat' (M ItE), with something that could be eaten on the move.

Caulkins outlined his plans to provide a spectacular swansong for missiles like the US Minuteman or Russian 55- 18 in the Journal of Pyroteclmics. It would make more sense to use these Cold War relics for entertairunent rather than brea.k them up for scrap, he argued. As the missiles returned to EaJ1:h.. they would release their cargo of thousands of artificial meteors, each weighing between 10and 100 grams. The meteors would burn up in the atmosphere, with diffe-rent colours depending on the chemicals with which they had been doped - sodium for yellow, strontium for red, and so on. Those in the £irst wave would create sonic booms. The noise would alert spectators to the display. ' It all happens pretty damn fast,' said Caulkins. However, he admitted that he hadn't worked out a solution to what was likely to be the most serious objection to his proposal: the rear that his pyrotechnic millennium party could be used as a cover for a real pre-(!lJlptive nuclear strike.

;:@3 lcy asteroids could power reactors in space Wacky ideas are commonplace among space scientists, but in 1993 officials at the US Department of Energy came up with a !!Cherne to top them aU. Searching for new ways to justify the

department's moribund programme to develop a nuclear reactor for use in space, they proposed capturing nea rby asteroids and comets and towing them into Earth orbit. According to an internal memo from the energy department, nuclear.powered processing plants in space would extract water from the asteroids. The water could be used to sustain humans in space and as a propellant for nuclear rockets, it said.

'Electric energy beamed to Earth from space would provide nearly pure electricity without SlobaJ warming. aod rain. strip mining or the hazards of fission products anywhere near Earth, three dozen years in the future,' the memo argued. There are believed to be thousands of asteroids relatively close to Earth, with water ice making up a large chunk of each. Some asteroids may be dormant oomets, which would contain an even greater proportion of water.

But had the idea gained ground, those running the prograoune might have had a tough time convincing the public that the project would not endanger humans on Earth.

~ Too damned hot In 1998, Biblical scholars breathed a sigh o f relief when two physicists and a bishop decided that the furnaces of heU are indeed hotter than heave:n. In 1{f72. science waded into the domain of theology with an anonymous article in Applied Optics stating that heaven must be hotter than hell. The paper noted that Revelati0fl 21:8 describes a lake in hell 'which bumeth with fire and brim· stone'. For there to be such a lake, hell's temperaturt> must be below the boiling point of sulphur, just under 7]8 kelvin a t atmosphffic pressure. Meanwhile, Isaiah )0:.26 describes the lighting in heaven, where 'the light of the Moon shall be as the light of the Sun, and the light o f the Sun shall be sevenfold, as the light of seven days'. Using Stefan's law, which states that the temperahlre or an object in thermal equilibrium is related to the fourth root o f the amount of light it reCeives, the paper 's authors calculated heaven's llmlperature to be a iWeltering 79B kelvin. However, in a letter published in the magazine Physics TOday, Jorge Mira p~rez and Jose Vina, physicists at the Uni versity of Santiago de Compostela in Spain, said that the Applied Optics authors misinterpreted the Isaiah passage, wrongly multiplying 7 by 7 to make the illumination in heaven 49 times as bright as that experienced by us on Earth. After Bishop Eugenio Ramlro Pose of Madrid confirmed thai only a single factor of 7 was intended, P&CZ and Vli"Ia recalculated heaven's temperature as 504.5 kelvin - blister ingly hot, but probably cooler than hell.

-Night of the living-impaired In 1998. the trade magazine Computer Technology ran an illuminating article by Michael Doherty about the technology of cflmmunicating with the dead.

~ Slumber learning In the summer of 1942. Lawrence LeShan of The CoUege of William &: Mary in WiUiamsburg, Virginia, US, stood in the darkness of a cabin in an upstate New York camp where a row of young boys lay sleeping. He Intoned a smgle phrase, over and over. 'My fingernails taste terribly bitter. My fingel'nails taste lerribly bitte.r .. ' Anyone happening upon the scene might have thought LeShan had gone mad, but he had not. The profcssor was conducting a sleep-learning experiment All the boys had been diagnosed as chronic nail-biters, and LeShan wanted to find out if nocturnal exposure to a negative suggesfion could cure then;l.lnitially he used a pho-. nograph to faithfully repeat the phrase 300 times a night as the boys lay sleeping. One month into the experiment, a nurse discreetly checked their nails during a routine medical CX<'Imination . One boy seemed to have kicked the habit. LeShan remarked that skin of a healthy texture had replaced the 'coarse wrinkled skin of the habitual blter'. Then, five weeks into the investigation, disaster struck-. The phonograph broke. Faced with having to abandon the experiment, LeShan began standing in the darkness and delivering the suggestion himself. Surpris.ingly, direct delivery had greater effect. Within two weeks, seven more boys had healthy nails. LeShan speculated that this was because his voice was dearer than the phonograph. Another possibility would be that his nlidnight confessions thoroughly spooked the children. 'If I stop biting my nails,' they probably thought, 'the strange man will go away:

Everything went well until 2) April 193), when Leuba recorded that his wife had made a confession. On one occasion, after her son's bath, she had 'bounced him up and down \vhile laughing and saying, ~ Bouncy, Bouncy".' It is not dear if this was enough to ruin the experiment. What is clear is that by month seven, R. L. Male was happily screaming with laughter when tickled. Undeterred, Leuba repeated the experiment after his daughter, E. L. Female, was born in February 1936. He obtained the same result. By the age of seven months, his daughter was Laughing when tickled.

However, one Sl!JlSeS a hesitation in his conclUSion, as if he felt that it all might have been different if only his wife had foUowed his rules more carefully.

1fTerror in the skies One day in the early 1960s, ten soldiers boarded a plane at Fort Hunter Liggett military base in California on what they thought was a routine training mission. The plane climbed into the clear blue sky, levelled out at around 5000 feet and cruised lor a lew minutes beiote s uddenly lurching to one side as a propeller failed. The pilot struggled with the controls and yeUed frantically into his headset. Finally, he made an announcement over the intercom: 'We have an emergency. An engine has stalled and the landing gear is not functioning I'm going to attempt to ditch in the ocean. Pleas(' prepare yourself.'

The task was something most people find diffIcult under nonnal circumstances: filling out insurance forms. A steward distributed the paperwor.k, explaining it as a bureaucratic neceSsity. If they were all going to die, the army wanted to make sure it was covered for the loss Obediently, the soldiers leaned forward in their seats, pencils in hand, and set to wcrk. They found the forms unexpectedly difficult todedphet and quite likely they attributed this to the distraction of approaching death.

In December 2001, a Canadian man and a J-metre, sBs-kilogram Kodiak bear were set to face off, in an attempt to test a handmade. purportedJy bear-proof suit. The suit and Its maker, Troy Hurtubise of North 6.'ly, Ontario, won a 1<}98 Ig Nobel pri7.e - awarded ann ually fo r improbable research projects - and an entry in the lOOl GllinIIesS BooIrofWorld Records for the most expensive research suit ever ronst ructed.

' I've never had a bruise,' said Hurtubise. But the su.i l had never-corne up against the very thing it was meant to protect against - a grizzly bear.

;{t- 'Bear-proof' suit to be put to the test In December 2001 , a Canadian man and a J~me tre. s8s-kilogram Kodiak bear were sct to face off. in an atl~p t to test a handmade, purportedly beal'-proof suit. The suit and its maker. Troy Hurtubise of North Bay, Ontario, won a 1998 Ig Nobel prize - awarded annually for improbable research projects - and an entry in the 2002 GI4iMness Book ufWurId Recurds for the most expensive research slllt ever constructed. Fifteen years of tinketing and US$l()(I,oClO went into the design, which incorporp.ted plastic, rubber.

chainmail, galvanised steel, titanium - and thousands of metres of duct tape. The suit proved itseLf to be virtually indestructible. It survived Iwostrikcs wI th a l )6-ltilograrn tree trunk, 18 collisions with a )-tOlme truck al 50 kilometres an hour, and numerous strikes by arrows, bullets, axes and baseball bats. 'I've nevl!r had a bruise: said Hurtubise. But the suit had never come up against the very thing it was meant to protect against - a grizzly hear. On 9 December 2001 , in an undisclosed location in westem Canada, all thai changed. In B 'controlled attack', the Kodiak,. a larger, heaviet- subspecies of the grizzly, was to put it to the lest. The bear, which appeared on TV commercials and in movies, was to be instructed by its handler to anack for ten seconds. Showbiz aside, Hurtubise stressed that it was a real bear. 'Real teeth, real claws, real power,' he said. He fully expeck.-d the outside of the suil to be ripped to shreds. 'The suit's a toy to the bear,' he said . ' He' lJ make his way 10 the

In 1999, Berger and Cunningham, biologists at the University of Nevada in Reno, wanted to know if animals behaved differently when their p~edators disappeared. Moose in Wyoming. for instance, were at the top of the food chain. Over the previous decades, all their predators had died out, mostly through human interference. But it was a different story in Alaska, where wolves and gri%zly bears still hunted the gentle beasts for supper.

By poring over o ur rich library of filth, researthers have been able to get a handle on just what makes a good swear word. II is not just its sound, said Tony McEnery, a Unguist at the University of Lancaster in the UK: after all, 'shot'. 'ship' and 'spit' arenotronsidered obscene, whereas 'shit' is. Besides, the German and French equivalents sound quite different and s till pack a very satisfactory p unch . It cannot just be about semantic content either, because the use of words denoting faeces or sexual matters in a medical context remains accepta~ ble. 'Something about the pairing of certain me~j~gs and sounds has a potent effect on people's emotions,' Pinker said. Swear words also go in and out of fashion in line with the taboos they breach. '''Damn'' was the undisputed king before "tuck" arrived on the scene,' said McEnery, ' but lost Its piquancy as the fear afbuming in hell faded.' 'Poxy', ' leprous', 'canker' and other disease-related words went the same way as hygiene improved. From the 19th ce1tury on, English speakers have mostly vented their frustra tion by reference lo two dirferent classes of taboo: the sexual and the scatologicaL Today ' fuck' reigns supreme, but there is still room for IMovation. So, what will be the next big thing in swearing? Most experts decline to predict any winners. 'Paedophile' seems to be an especiaUy offensive thing to call someone today, explaIned McEnery, and therefore a good candidate, but there is no evidence it is gaining ground as a swear word. 'Something is missing with that word./ he said. Pinker said the word 'cancer', while not yet obscene, is acquiring taboo characteristics - note how it is aiten referred to as 'The Big C . Jay road-tested a few contenders of his own. He once muttered 'Expletive!' on a golf course, and got some strange looks. You can't impose swear words on a language, he noted, they arise organicaUy. Just becaUSt' yOll personaUy dislike cheese, shouting 'stilton' out loudly is unlikely to catch on.

been a matter of debate But in lOOl, one man believed he had the answer. Michael Levitt, a gastroenterologist at the Veterans Administration Medical Center in MinneapoUs, had been studying flatus for over JO years and solved numerous m)'l>teries that might otherwise have troubled the OaMent reader. WeU known in gastroenterological circles for his painStaking research and undying enlhusiasm, Levitt had written more lhan 100 papers on this subject and is acknowledged as a world authonty. Amdes about hun and his work have appeared in everything from Tilt Sydney Morning Ht'rJlld to T1~

Readers would write angry letters to lus employers complaining that his research was a waste of money, It became so bad that he eventually refused to talk to thp press for (Pill" of jPnpardi.~;ng his career. Just what went wrong? Part of the problem was the mirth-provoking {\8tureof the topic itself, The temptation to tum out stories brimming with puns and farl jokes was often too great for joumaUsts to resist, and the tone of the story inevitably colours Levitt's image in the mind or Ihe readers. The Sydney Momillg Herald, for example, began its story about Levitt with the euphemistic headline 'Tail wind'. Tht Washingloll Post started cheekily with 'Waiting to inhale' but dampened further enthu..,iasm with the sub-heading 'Mainstream and alternative practitioners agree that diet is central to controUing flatulence'. And online magazine Salon.wm plumped for ' Dr Fart speaks'. Levitt's work attracted the media b«ause it is serious research on a snigger--inducing topic. For instance, he was the first to COI'nDly identify the gases that make farts smell. Pre-ViOU5ly. researchers had suspected that the guilty parties were roul-smclling compounds such as indole and skatole, created by the breakdown of amino acids in the gut. But nobody had ever bothered to check.

bvaluating a smell is a diffruh task. so Levitt turned to tlk' nOSo("S of two people with a rather unusual abi!Jty. 80th "lUld Idenhiy dilkrmt sulphur-ronl'auting gases purely by .l1wll fhcse lucky mdlViduals were asked to evaluate the ,til''' of 16 healthy men and women who, the previous ~Yt'l'llRg. had eaten 100 grams of pinto beans to ensure ample ~A'I production.

But unlike Star TrtX's £nlerprise, it was once hoped that spacecraft might use a less savoury energy supply than Scotty's beloved d ilithium crystals: human waste. In 1999, NASA enlisted the aid of Advanced. Fuel Research of Connecticut in a $600,000 pro;ect to tum astronaut waste - either faeces or some plastics - into a power source (or spaceships using pyrolysis: the breaking down of waste by heating it in the absence of oxygen. . Normally, when organic molerules such as those found in faeces or in p lasbc are burned, they combine with oxygen in the air, producing carbon dioxide and water. But in pyrolysis, there is no oxygen to combine with. so the molecules break their bonds and rearrange themselves into smaller molecules. According to AFR scientist Mike Serio, '"Things start breaking down at about 350 '>C, and what you start making includes a lot of liquid§.. At 600 "<:or65O "C, you break down the liquids into gases.

WhaJes may be the biggest creatures on the planet, but they also swim fast and dive deep, so are notoriously di£fLcuJt to study. Fortunately, you can te.1I a lot about an animal by studying what it leaves behind. In faeces, researchers can find clues ilbout an .mimal'& distribution,. abundance, sex and reproductive status, stres5 le,-e1s, health and vita'lity. Spotting scat samples, which hang just below the sea's surface before they break apart, is far more difficult than finding the animals th .... mselves, and that's where dogs like Fargo come in.

:-W Fa ki ng it In I~, Richard Yeo and Debra Welchel of the KimberleyClark Corporation in Dallas, Texas, invented a recipe to simulate somethtng you rrught have thought was fairly abundant in America: human faeces. Their mix consisted of pclyvinyls, starches, natural gums and gelatins, all water-soluble, plus msoluble fibres and resins. Add water to this and you would get a synthetic turd 'as close to the real thing as possible', Yeo told the New York Times. This is impressive, but by now a question may well have occurred to you: why would we need it? The answer was that Kimberley-Clark makes nappies and adult incontinence pads and these products must be rigorously tested. 'But the technicians have some objecbon to handling the real thing.' Yeo said, add ing that actual faeces are 'a (ann of biologically hazanious material', In addition, the firm's labsmig.ht havefOWld they needed, say, 10 kilograms of faeces 319 o'cloc!c.on a Monday morning, to begin tests on a new range of nappies. The real thing. Yeo complained. can be 'a bit difficult toobtain.even from infants'. Any scientific endeavour typically starts with a review of the existing literature. 'We had fundam£!ntal studies of real faeces,' Yeo said, 'so we knew what was needed.'

The yuck factor

Most people go through life unaware how easy it is to fix the probU!m. According to William Silvers, an allergIst from. Vail, Colorado, whose fascination wIth runny noses won him recognition as The Skier's Nose Doctor', people don't do much about their sudden bouts of sniffling because they ilI1! simply not seen as a medical issue. In fact, Silvers c.launed, when faced with the grim realisation that their nose has begun to leaK, the majority of folks ta.ke the matter into their own hands - quite literaJly. 'That's why they make cycling gloves with absorbent terry doth on the outside: he said You thoughllhey were designed to mop sweat? 'Well, I ~ them for my nose: he replied, unabashed . Silvers has been researching cold-induced rurmy noses Since the 19Bos, usmg the slopes of several Colorado skl resorbi as his field lab. And his findings on people's nose habits make intriguing reading. Women tend to be better prepared and often carry tissues, fOf" example. Men prefer their sleev'-'5, or in certain situahons (especially in the great outdoors) may even resort to what he refers to as ' the farmer 's blow': block one nostril and blow, then repeat for the other side. 'They blow it out and keep on going,' said Silvers. Children just ignore it. Wiping may be their parents' favoured option, but a good old snort to recycle that lovely snot is good enough for the Iuds. 'It doesn't bother them as much,' he said, Silver's fa!C:ination with the runny nose doesn't end there. He could even teU you how common the phenomenon is based on quantifying the usage of tissues by placing boxes of them nearski ults.Thecolder it is on the slopes, he found , !he faster the tissues diSappear. A few teams around the world have carried out studies of cold-induced rlUniti5 in animals as well as humans. But the most fiendish snot-inducing experiments have involved people. At Johns Hopkins Univt'TSity School of Medicine in Baltimore, for example, volunteers were ASked to inhale cold dry air for 45 minutes so thai scientist5 could measure their nasal e:ntissions in search of any hint of why the phenomenon

Surprisingly, both nostrils wereequaUy prolific producers of mucus in this situation. Of course, plenty of people have their own pet theories as to what causes the problem. The ancient Greeks thought that a runny nose was a sign that the brain was turning into mush. One day, science may reveal just why copious amounts of watery goo end up on our sleeves when we least expect it. Until then, only the nose knows,

~; Thar she blows What is the stranges.t thing you could do with a remote-controlled toy helicopter? Strapping on a few Petri dishes and flying it through whale soot must be high on the list. That is how Karina Acevedo-Whitehouse, a veterinarian and conser· vaUon biologist with the Zoological Society of London. has spent much of her time over the past few years. In :woB, Acevedo-Whitehouse nlade it possible to study the viruses, fungi and bacteria that hitch a ride in whale lungs EO(" the first time. Researchers can fairly easily take blood ·samples from other marine mammals, such as seals and sea lions. but a whale's sheer bulk means that such a sampling would be fatal. 'Scientists have always found it difficult to study diseases in whales because of their size,' explained AcevedoWhitehouse. But after witnessing the sheer power of whale 'blows' in the Gulf of California.. she rea]jsed that this would be the best way of sampling the insides of a lh'e whale in the <xcan.

She first tried tying herself to a research boat and leaning (We.rboard to catch 3 bit of whale snot in Petri dishes. 1t worked,' she said, 'but it wasn' t very safe.' Her technique became more sophisticated. For species like grey and sperm whales that did not mind being dosetoa boat, the researchers attached their Petri dishes to a long pole and held them out over the blows. With the shyer blue whale, they had to resort to miniature helicopters. The Petri dishes were attached beneath the metrelong choppers, whld! were remotely flown through whale snot_ 'The whales definitely notice the helicopter,' said Acevedo--Whltehouse, 'they tunl on their lIides to look at it But they don't seem bothered and we don't even touch them.'

In their experiments, 19 female and 14 male college students acted as od~ur donors; they were asked to refrain from cleaning their teeth or eating garlic or heavily spiced foods during the five days of tl\e study. The odour judges consisted of five male and five female students. Odour donors and judges were separated by a sc.reen in a large, well-ventilated room.

Health research from the US reveals an unexpected medical nsk factor: living too close to the doctor. The Mayo Clinic in

Minnesota was worried that after an appointment many patients either forget what their doctor told them or ignored the doctor's advice anyway. To find out, researchers monitored 556 people on visits to

their GP, noted what the doctor told each patient, then followed the patient home and asked what they had heard. The

patients 'did not mention 68 per cent of the health problems diagnosed: the study found, 'including 54 per cent of the most important problems', The study suggested that 'denial' and 'sclL-ctive Listening' were the main techniques used by the plltit'nts to i&,on' mPdkal advirt".

that 'patients who travelled a considerable distance for their care were most likely to remember and fo llow what their doctor had discussed with them'.

~ When is a person dead? In 1962, R. S. Schwa. a neurologist at Harvard University, stated that death in humans is certain if an electroencephalogram (a measure of electrical activity in the brain) showed continuous flat lines without any rhythm for an hour or more, even if the heart was beating. The electroencephalogram would also show a resistance of over 50,000 uhms and ;uu1d not register a discharge even if a loud noise was made next to the patient.

1t How does it feel to die? Is it distressing to experience consciousness slipping away or something people can accept with equanimity? Are there any surprises in store as our existence draws to a close? These are questions that have plagued philosophers and scientists for centuries, and chances are you've pondered them too

occasional ly. None of us can know the answers for S~ until OUI own time comes, but the few individuals who have had their brush with death interrupted by a last-minute reprieve can offer some intriguing insights. Advances in medical science, too, have led to a better understanding of what goes on as the body gives up the ghost. Death comes in many guises, butane way or another it is usually a lack of oxygen to the brain that delivers the coup de grace. Whether as a result of a heart attack, drowning or suffocation, for example, people ultimately cUe because their neurons are deprived of oxygen, leading to cessation of electrical activity in the brain - the modem defmilion of biological death. If the flow of freshly oxygena ted blood to the brain is s topped, through whatever mechanism, people tend to have about ten seconds before losing consciousness. They may take many more minutes to die, though. with the exact mode of death affecting the subtleties of the final experience. Read on for a brief guide to a few of the many and varied ways death can suddenly stri ke.

'Survivors of haemonh.agic shock describe: many different experiences, ranging from fear to relative calm.' Kortbeek said. ' In large part this would depend on what and how extensive the associated injuries were. A single penetrating wound to the femoral artery in the leg might be: less painful than multiple fractures sustained in a motor vehicle crash.' Fire

Long the fate of witches and heretics, buming to death is torture. Hot smoke and flames singe eyebrows and hair and bum the throot and airv,lays, ma'king it hard. to breathe. Burns inflict immediate and intense pain through stimulation of the nociceptors - the pain nerves in the skin. To make matters worse, bums also tri~ a rapid inflammatory response, which boosts scnsitivity to pain in the injured tissues and SUI"-

rowuling areas. As bum intensities progress, some feeling is lost but not much, according to David Herndon. a burns-care specialist at University of Texas Medical Branch in Galveston.

Some victims of severe bums report not feeling their injuries while they are still in danger or inlent on saving others. Once the adrenalin and shock wear off, however, the pain quickly sets in. Pain management remains one of the most ch(l\lenging medical problems in the care of bums victims. Most people who die in fires do not in facl d ie from burns. Tht' mO!';i r"nmmon cau!'.P of dp.aU\ is inhaling toxic gases carbon monoxide, carbon dioxide and even hydrogen cyanide - together with the suffocating lack of oxygen.

Depending On the size of the fire and how dose you are to It, concenl.rations of carbon monoxide could start to cause headache and drowsiness in minutes, eventually leading to unconsciousness.

Explosive decompression Death due to exposure to vacuum is a staple 01 science fiction plots, whether the unfortunate gets thrown from an airlock or ruptures their spacesuit.

This occurred on the Russian SoYUZ-11 mission in 1971, when a seal leaked upon te-enny into the Earth's atmosphere; upon landing all three flight crew werdound dead from asphyxiation. When the external air pressure suddenly drops, the air in the lungs expands, tearing the fragile gas exchange tissues. This is espeoally damaging if the victim neglects to exhale prior to decompression or tries to hold their breath. Oxygen begins to escape from the blood and lungs. Up to 40 seconds after the pressure drops, bodies begm to swell as the water in tissues vaporises. though the tight seal of skin prevents them from 'bursting'.

Dying is painful, deeply distressing and may take several minutes. Electrocution was first approved by the state of New York in '1.888, and several hundred people .. year were executed in the US for rape and armed robbery, as well as murder, until the end of the lC}60s. The prisoner is fastened to a chair by his chest, groin. arms and legs to prevent violent movements and to keep the electrodes in place . These are moistened copper terminals attached to one calf and a band round the head. Jolts 014 to 8 am peres at levels between 500 and 2000 volts are applied for half a minute at a time, and 11 doctor inspects the condemned to decide if death has occurred or another jolt should be adm.ini!tered. In 1.982. John Louis Evans was shocked for half a mmute. Th.is broke the leg electrode, which was reattached. A second attempt failed to kill him and smoke was seen coming out of his mouth and left leg. He was given a third dose. II took ten minutes before the attending physician certified him as being

dead. The. effects of accidental eJectrocution are bums, respiratory paralysis and cardiac arrest. l1\e electric chair was introduced because it was believed. II causes instant and painless death. Close observation has shown this is clearly not the case. There is no reason whatsoever to believe that the. condemned person docs not suffer severe and prolonged pain. The prisoner is SO firmly fastened to the chair that he cannot move. The large amount o f energy in the shock paralyses the muscles, presumably leading to the belief that the failure to move meant the prisoner was not suffering pain.

The first is intravenous injection. In December 1982, Charlie Brooks of Texas had his vein cannulated by il physician. Then.. from outside the execution chamber and unseen by the prisoner. a mixture was injected; this consisted of the rapidly acting anaesthetic Pentothal-(:urart' to paralyse the muscles, and potassium chloride to stop the heart. The condemned man would have gone off to sleep in to to 15 seconds, ne\-er to wake again. 1l\t~ prisoner would have suffered no more pain than a patient being given Pentothal before an operation. However, the physician gave an overdose and the condemned man died under anaesthetic from central respiratory depression. Other states have chosen gassing In September 11)8). Jimmy Lee Gray was strapped to a ch3ir in an airtight room. Sodium cyanide crystals were dropped mto II bath of sulphuric add below his chair by depressing a lever from outside. This c:reated hydrogen cyanide gas and the condemned man inhaled it, A sllfficient concentration to ronstitute a lethal dose would take several seconds to accumulate, depeu:ling on how hard he bied to avoid inhaling. It would cause. acute difficulty in breathing, ilSphyxia and, possibly. pain in the stomach. The prisoner wouJd be severely distressed and in pain during the whole procedure. The resuJting hypoxia would cause tum to have spasl)lS as in an epileptic fit, visible if he were not bound firmly. The prisoner would have cUed of inhibition of respiratory enzymes.

But she did not lie. The Times ran 8 follow-up under the headline 'Dead Spirituali!:tSilent'. A better-pedigreed variation of the Bradford experiment was undertaken by the phYSicist Oliver Lod~, once the pnncipal of the University of Binmingharn. Prior to his dE'ath in 1940, he devised the Oliver Lodge Posthumous Test. The goal, again, was to prove the existence of life after death. Lodge composed a secret message and sealed it in a packet (the Oliver Lodge Posthumous P'acket) SO that when,. after his dea Ul, he told mediums (four of them, recruited by the Oliver Lodge Posthumous Test Committee) what the message was. their stories could be checked.

As patients came outof anaesthesia, psychologist Bruce Greyson interviewed them about what they remembered of their time in the operating room. So far there have been no surprises. Other, that is, than the surprising cooperation of a team of cardiac surgeons. Heart surgeons who believe that a consciousness can ocr:asionally perce.iVl' things in an extrasensory manner, independent of a brain and eyeballs, are less rare than you might tltink.

This is exactly what a Massachusetts physlcian named Duncan MacDougall did, beginning in 19(>1, using a trickedout industrial silk scale (see page 43) HJs post at a tuberculosis sanatorium provided MacDougall with ;J steady source of study subjects.. He weighed six m('(l as they rued" and there was, he said in a series of articles in Americnu Medicine, always a down-tick of the needle.

: Hard to swallow J\s a junior doctor at the Royal Perth Hospital,. Western Australia, Barry Marshall was so sure the medkal establishment was wrong about the cause of stomach ulcers that he swallowed the bacteria he believed were to blame. It still took years to convince everyone - but it was to win him it share in a Nobel prize, alongside Robin Warren. New Scientist interIfiewed him in 2006. What made you decide to swallow the bacteria? It was so frustrating to see ulcer patients having surger/. or l'ven dying, when I knew a simple antibiotic t:reatment could (j)( the problem. Back in 1984, conventional medical wisdom was that ulcers were caused by stress, bad d iet, smoking.. alcohol and susceptible genes - and that no bacteria could survive in the stomach. Working with pathologist Robin Warren, I found a bacterium caUed Helicobacter pylori in all duodenal ulcer patients and in 71 per cent of those with gastric ulcers. We tried. to infect animals to prove this bacterium was the culprit but that failed, so we had to find a human volunteer. Why did it have to be you? I was the only person informed enough 10 consent, 50 I decided to be my own guinea pig. J didn't seek approval from the hospital's ethics committee because I didn't want to risk being turned down, and I didn't even tell my wife until I had swallowed the baderia . By then I had successfully treated several patients suffering from H. pylori infections using antibiotics. so it seemed that 1 had a cure. WhJ:t happened ;after you swallowed the bacteria? I was fine for three days, then began to feel nauseous, and soon began vomiting. My wife told me I had 'putrid breath'.

After"len days, a biopsy confirmed the bacteria had infected my stomach, and the stomach wall was inflamed with gastritis, which can eventually lead to ulcers. My experiment overturned 100 years of knowledge about uiceJ'S. We published our results in The uwut. Was it hard to convince the world that such a 'miracle CUJ'e' existed? Yes. When The Lancet finally used the word 'cure' in ]1)89 we thought that everybody must believe us now, but it was another 8 long years before most people in western countries W(!J'e aware that H . pylori caused ulcers. In the meantime, millions of people had taken unnecessary drugs or had sUigery, at a cost of billions of dollars. Did you find that infuriating? At the time , thought it was somewha t immoral. because doctors who were sceptical about H. pylori were making decisions that permanently affected the Jives of their patients. It was very easy for them to stick with the old treatments.

Having observed that yeUow fever ran riot during the summer, hut disappean?d OYer the- winter, Ffirth hypothesised it was not a contagious disease. He reckoned it was caused by an excess of stimulants such as heat, food and noise. To prove his hunch, Hirth set out to demonstrate that no matter how much he exposed himself to yellow fever, he wouldn't catch it. He started by making a small incision in his ann and pouring ' &esh black vomit' obtained from a yellow·fever patient inlo the cut He didn't get sick. But he didn't stop there. His experiments grew progressively bolder. He made deeper incisions in his arms 1010 which he poured black vomit. He dribbled the stuff in his eyes. He filled a room with heated 'regurgitation vaJ'Qurs' - a vomi t sauna - and remained there for Iwo hours, breathing in the air. He experienced a 'greatpain in my head, some nausea, and perspired very freely', bUI was OthC!JWLSe OK. Next pfirtJ\ began ingesting the vomit. He fashioned some of the black matter into pills and swallowed them down. He nuxed half an ounce of fresh vomit with water and drank it. 'The taste was vcry slightly acid,' he wrote. 'II is probable that if I had not, previous to the two last experiments, accustomed myself to tasting and smelling it, that emesis would have been the consequence' Fmally, he gathered his courage and quaffed pure, undiluted black vomit fresh from a patient's mouth.

Two surgeons had finished work for the day. But instead of going home, they began to prepano for one more operation - a little out-of-hours experiment intended, to advance the art of anaesthesja. August Bier was a rising star at the Roya1 Surgical Cliruc in Kiel, north Germany. HJs young assistant, August Hildebrandt, had agreed to help him. What happened next was not so much heroic as comic. Just one little mistake and courageous selflessness turned to black comedy. It made Bier 's name. But the events of thai evening wouJd be forever etched on Hildebrandt's memory, not to mention several other parts of his body. In the lB90s, general anaesthesia was decidedly d cdgy. Olioroform sent patients gently to sleep - but there was no room for mistakes. A few drops too many and the patient would be dead befon! the surgeon picked up the sca1pel. Ether wasn't quite so dangerous, but it was slow to act - surgeons sometimes started to operate before their patients had gone under. The survivors suffered unpleasant ~ide eHectsfrom violent headaches and vomiting to ether pneumonia. Bier reasoned it should be possible to banish sensation from most of the body without knocking the patient out com· pletely by injecting a small dose of cocaine into the cerebrospina1 fluid that bathes the spinal corel. He tried his technique on ha1f a dozen patients. They lost sensation from the lower

part of their bodies long enough for him to carve out chunks of diseased bone from their ankles, knees and shins - and even the thigh and pelvis. 'On the other hand, so many romplaints had arisen in association with this method that they equalled the complaints usually occurring after general anaesthesia: he wrote. 'To arrive at a valid opinion, 1decided to conduct an experiment on my own body.' The procedun! was simple enough. Hildebrandt had to mdke a lumbar pWlCture by plunging a large needle through tht! membranes that protected Bier's spinal cord into the Ouid·filled space bf:...neath l1'\t>rI tw had to fit it syringe on tlw needle and inject a solution of cocaine. But preparations for the experiment had been less than meticulous. Hildebrandt made the lumbar puncture. Then.. with his finger over the hub of the needle to prevent fluid from leaking out, he took up the syringe of oocai.ne -only to find. it was the wrong lit. As he fumbled with the needles, Bier's cetebrosp~ nal fluid began to squirt out. Horrified, Hildebrandt stoppffi .1nd plugged the wound. This was when the pair should have called it a day. Instead. Hildebrandt offered to take Bier's

After 4) minutes. the effect of tM roaine began to wear off. The two surgeons, one missing a significant amount of

cerebrospinal fluid, the other battered, burnt and suffering from serious stab wounds, went out for dinner. 'We drank wine and smoked several agars,' wrote Bier. The next moming.

When he finaUy gOI up again he felt quite well. 'I was perfectly able to tolerate the strain of a week's hunting in the mountains,' he wrote. Hildebrandt didn't escape so lightly. The first night he was violently iU. He had a splitting headache and was sick. But someone had to tend to the cUnic's patients and, with Bier in bed. the job fell to him. Each morning for the next week, Hildebrandt dragged himself to work. Each afternoon, he staggered home and collapsed into bed. 'Dr Hildebrandt's legs were painful and bruises appeared in several plares,' wrote Bier, rather understating the case. When Bier wrote his ground-breaking paper dnc:ribing the experiment, he gave a blow-by-blow account or what Hildebrandt had endured. As far as Bier was concerned, the experiment was a huge success. He had shown thai a tiny dose of cocaine could deaden sensation for long enough to perform a major operation. Spinal anaesthesia was far safer than general anaesthesia, and within two years surgeons amund the world were wing it. Bier put the headaches down to the loss of cerebrospinal Awd, and he was right - this was finally proved in the 19)05.

Hildebrandt, though. had gone right off Bier and became one of his most vehement critics. When a row blew up over who had really been first to invent spinal anaesthesia, HildebrAndt championed Bier 's rival, an American neurologist called Jame!! Coming. Hildebrandt never said why. Perhaps he wasshoc:ked by the zeal with which Bier had battered him. Maybe he was mUled because in the end Bier was recogrused as a pi()n~ring surgoon,. while he was forever known as the man whose boss had rugged his testicles.

But they didn't say when or how. 'We have 10 be pretty devious,' he said. An assistant uncoiled a rope, laid it across the lab and instructed thevolunteers to walkover it normally. Thevictims approached the rope cautiously, but relaxed once they had passed it, thinking they were safe. 'And then we trip them.' Grabiner said. An aluminium box popped out of the Ooor, ca tchmg the unsuspecting victim's foot as they 5W\mg it forward. This work produced pU7..z.ling results. When people trip, the upper body pitches forward. BecauSE' older people have weaker muscll!S, they are less stable when they walk. So Grabin~r expected 10 find that weak: people would pitch further forward than st:rong~ JX.'Ople But this was not what his results showed. Weak or strong, people always tilted to about the same angle when they were tripped. He also found it- as difficult to get strong young people to fall down as their weaker cohorts. Unlike the younger participants, most of the elderly vol· unteers were easily Ooored. But there was 3 complication. 1l\e study Iound there were two categories of older falle r; the slow and the fast.

Prom this. she Found that people used the leg that had not been tripped to win them some extra time to recover. When one leg was tripped, they immediately pushed off with the other leg, as if hopping. but also bending their knee.

;$ Effects of hallucinogenic drugs in blind people How do drugs such as LSD and rnescaline produce their unusual psychedelic effects and visual hallucinations? These consist of brightly coloured lights, geometric dcsigns and impainnent of colour values and space perception.. In 1961, Dr Adrian M. OstfeJd of the University of illinois showed that hallucinogenic drugs produce abnormal changes in the retina, affKting the functions of the rod-cell Light receptors of the retina, probably by interfering with their oxygen supply. He then gave LSD to 18 blind people who had not been blind from birth. A number reported 'seeing' white lights and coloured flashes, simUar to those described by sighted patients who had the visual area in the occipital part of their brain stimulall.>d elt!ctrkally wtder local ana~th~ia . But when people who had been blind since birth were given 1..50 they did not experience these visual hallucinations, p resumably because they had no appreciation of light o r colour. They did, however, experience auditory, olfactory and tactile hallucinations.

In a paper published in the journal Nature, they suggested that it wasn't quite as simple as one might have expected. Charles Oanvin WAS intrigued by the ineffectiveness. of theself-administererl tickle, but his interest was mainly in the biological value of ticklishness and laughter. The au~ of the Nntlm paper (L. W~skrantz and C. Darlington of Oxford, and J-Elliott otSheffield), on the other hand, set out to analyse

whM mechanisms are actually involved. To do this they lined up JO intrepid volunteers brave enough to be stimulated by a He;)th Robinson-type bclde: apparatus..

Three types of tickJe were administered: the first by an experimenter, the tickled subject remaining passive; the next was self-administered. by the subject who moved the handle of the tickle apparatus; the third was done by an experImenter, but with the tickled subject's hand on the handle. The idea of this last method was to see if there was any effect on the ticklishness when the subject went through the motion of tickling but was not actually in command. Sure I..'nough., the efficacy of tickling was greatest when done by someone else, least when self-administered, and Intermediate when the subject participated in arm movements. Clearly, this participation helped eliminate ticklishness, but not completely. Weiskrantz and his colleagues thought there might be two factors at play m self-tickling. One was a sorl of negative fuedback from the afm movements doing the tickling (Of going through the motions, as in the experiment). 1be other was the 'c:onunand signal' generated when the subject deddl,>d to tickle himself.

AU but the saintliest of us have had them. Hangovers approaching nt'ar-death experiences. Raging thirst, thump"" ins headache, wobbly limbs and nausea. Worse, there's no magic bullet to make us instantly well Thousands of years after the first 'morning after the night before', we can send people to the Moon and create computenJ o f mind-numbing power. yet we are still far away from a science-based, expenmentally \"l.'rified h.:mgOVC1' CUl't. Why? The simple answer is thalln the eyes of most governments, doctors and industries, a hangover cure would trigger a catastrophic upsurge in alcohol abuse, tempting mild drinkers to overinduJge. Hanguven; are, aft!:"c all, nature '~ way uf ltily ing 'dun' t do tillS tu youl"5f'U' So don't expect to find the nlilglCbullet nesUing anywhere in the scientific literature. The research hasn' t been done nor is it ever likely to be done. But there is plenty of research on what a1cohol does to the body. Armed with this knowledge, many alcohol researchers have speculated about the best hangover remedies. In the interests of easing global pain, New Scientist decided to test some af the top tips to emerge from this research. A panel 01 it dazen or so intrepid volunteers agreed to averindulge an faW" successive weekends, trying a different '1!Un!" each time.

Most sore heads will have to be soothed with the Ira~ ditional remedies our researchers tried - plenty of water before beet something sugary, plus cysteine-rich foods sud, as eggs, which help mop up any damaging chemicals. To take the edge off headaches, pop an aspirin or ibuprofen before bed.

But presumably he'd empathise with the plight of Mr WOTthing. After aU it wasn't just one, but two careJessly lost empty bottles of beer that caused his collider to, er, faiJ to collide after its very expensive upgrade. Oh. it's easy to mock, of course.

WhUe we're on the subject of mockery, it is instructive to recall that the art has a long history in the field of science. Back in the IB90s, before the nature of electricity was truly understood, an aspiring student was sitting an oral exam at Oxford University. He was asked if he knew what electricity was. ' I' m sure I've learnt what it is: s tuttered the nervous candidate. 'but now I've forgotten.' 'How very unfortunate; replied the unimpressed examiner. 'Only two people have

unfortunate scientific endeavours. However. a charge of 'being a little unfair' cannot be levelled at us when we consider the case of Pierre Pumpille, who provides one of the stories that fail to make II into this chaplet. In a feature on the excesses that men wiU go to in order to prove their machismo, Ntrtll SciCli/1St told the story 01 the headstrong Frenchman who had shunted a stationary car a distance of 2 feet by headbutting it. 'Women thought I was a god: he explained from his hospItal bed . We disagree, and despite using his head in a way that scientists usually do not in order to prove his point. he fails to make Ule grade_ For while stupid, his researeh cannot be declared a 'blwlder ·. !-Ie actually meant to headbutt the car.

That might, in most people's books, constitute a strong case for inclusion in this chapter. but we are not so presumptuous.

1EThe trouble with rockets Rocket science has a deserved reputation for being tough, SO it should be no surprise that things can gel a little bumpy when it comes to designing and testing a launcher. Just ask Elon Musk, the millionaire founder of PayPal and rocket company SpaceX. His fll'S! rocket, Falcon r, was scheduled to lift off £rom the Pacific atoll Kwa~lein in November 2005. at which point the problems began. First. unplanned engine tests used up more hquid oxygen (LOX) fuel than expected, then the LOX generator broke down. A shipment of fuel was ordered from Hawaii, but the tanker sprang a leak and arnved onJy onefifth full . There was just enough to launch, but a valve was left open during the final preparations, allowing mort' fuel to waste away, so the launch had to be cancelJed. A fresh shipment of LOX arrived a month later but disaster struck again. High winds hit the atoll, and to be on the safe side, engineers decided to drain the fuel from the rocket. A faulty pressure valve caused a vacuum to fonn inside the main fuel tank, sucking in its soft sides like a crushed beer

can. After three months of repairs, by March 2006 Falron 1 was ready to go. Seconds after launch., howeYV, the main engine sprang a fuclleak. leaving a trail of flame in the rockers wake as it spiralled off course and crashed v.'ithin sight of the disappointed engmeers.

The torpedo was a research tool taken to Antarctic waters on board the Aurora AIlStfalis, the research vessel of the Australian Antarctic Division. The ship returned to Hobart without the torpedo and the AS)5,OOO worth of computet equipment it carried. On its maiden voyage, the torpedo failed to return as it was programmed to. The obsolete weapon was bought from the Royal Australian Navy for A$150 and fitted with sonar equipment. The aim was to bounce signals off the bottom of the ice pack to measure its depth. It was programmed to do a V-turn under the ice before being retrieved. In open water, the device performed perfectly, but under the ice it failed the test. 'There was one bright spot,' said Garth Paltridge, director of the institute. 'Part of the exercise was to test the logistics of operating in such a hostile environment. In that sense it worked perfectly.' After being lowered into the water and before its motor started, the waves turned the torpedo about 90 degrees from its course. Its guidance system never brought it back on track. Also, it was so cold, about -20 DC, that the ship's tracking system stopped working.

Particle beams hit the bottle Physicists starting up Europe's most powerful particle acrel· erator in 1<}96 hoped to detect fundamental particles not seen since the beginning of the universe. But when the Large EIec-tron Positron (LE P) collider at the CERN particle physics Laboratory in Geneva resumed operation after a £210 million upgrade, nothing happened. The faull , it emerged, was due 10 two empty bottles of Lager. LEP sits in a 27·kilometre circular tunnel. In the 19&5, physicists used the accelerator to pmve the existence of the W and Z particles, whi.ch carry the weak nuclear force. With the enCTgY of LEP's particle beams nearly doubled to 162 gigaelectronvolts, the _ccelerator had a chance of uncovering the Higgs boson, which was thought to endow other particles with mass. When LEP2. as the upgraded machine was known, was switched on.. beams of electrons and positrons were supposed

to travel in opposite directkms round the giant circuit, but neither beam made it. CERN's investigators homed in on the section of the ring causing the trouble. When they dismantled ii, they found that the high-vacuum tube through which the beams travel had been blocked by two beer bollle;. No damage bad been done to LEP2. Bul the incident had a 5cicntific cost. 'We lost five valuable da)'5 of physics: said Stephen Myers, who was in charge of LEP2.

The images were sharp in the centre, but far more blurred than expected at the sides. A laborious investigation (ollowed, with engineers dismantling the optics and reassembling them daily, but finding no answer. Then one day, an engineer mistakenly replaced one of the four lenses back.-to-front. The images improved spectacularly, 'The oext observations were just "Wow!",' said Christian VeilJet, the observatQry's director. 'The image quality was just what it should have been.' No one understood why the back-Io-front lens worked SO well, or why it didn't work when it was oriented as planned. 'Th.iIIt has been frustrating. but it would bea waste of resources

~ Elephants on acid What happens if you give an elephant LSD? Researchers solved this mystery in August 1962, when Warren Thomas, director of Lincoln Park Zoo in Oklahoma City, fired a cartridge-syringe containing 297 milligrams of LSD into the rump of Thsko the e1ephant. With Thomas were two colleagues from the University of Oklahoma School of Medicine, Louis Jolyon West and Olester M. Pierce. The dose was about 3000 times what a human would typically take. Thomas, West and P;erce figured that if they were going to give an elephant LSD they'd better not give it too little. They later explained that the experiment was d esigned to find out if lSD would induce musth in an elephant - musth being a kind of temporary madness male elephants sometimes experience dunng which they become highly aggressive a,nd secrete a sticky fluid from their temporal glands.

In an article published four months after the event in Seu!rIct, the three scientists sheepishly concluded: ' It appean; that the elephant is highly sensitive to the effects of LSD: The experiment instantly made heacUines.

,1: Furry submarines embarrass Swedish navy When IS a sub not a sub? The answer, as an embarrassed Swedish navy had to admit in 1996, is when it's a mink or an otter. What the navy thought was the sinister sound of Soviet propellers was, in fact, the furious paddling of little legs. A scientific commission set up by the government .1nd chall"ed by the former djrector of the SwedISh Engmcenng Science Academy, Hans Forsberg. concluded that most o f the invading !lubmarines ~ported by the navy were mythical Of more than 6000 reports of 'alien underwater activity' between -19fjl and 1994. the commission found firm evidence for only sur. incidents. In every oth~ case the eVidence, often based on sightings by the public, was unreliable. The navy claimed that one underwater noise. similar to the sound of frying eggs, was caused by bubbles from submruines. It was more likely to have been caused by the natural movement of water, said the commission.

On 40 occasions between 1992 and 1994, a defence network of microphones attached to buoys detected the sound of bubbles caused by a rotational movement in the water. The navy estimated the speed at up to laO revolutions per minute, and assumed it must be submarine propeUers. But Ule navy was wrong.. said the commission. According to its secretary, lngvar Akesson, tests with swimming mink or otters showed that they could produce the same readings as propellers. 11 is very pw:zling, but they do,' he said. The navy accepted that in some cases it might have confused the two sounds.

But once scientists got their teeth into it, just as with any discipline, there was going to be no lying back and thinking of Einstein. It's possible that scientists were desperate to prove that they were as normal (or at least as open-minded) as the next person. a process that perhaps reached. its apotheosis when, in the mid-1990S, an American science radio show thought it prudent to release the annual beefcake calendar Studmllffins ofSdenu. Science has been apologising ever since. But in the noughties we are all a little more grown up than we were. Or at least we hope weare.

The resuJts appeared to fly in the face of reseatcll such as the Hite Report on women's experience of sex. Over the past decade or so it has become recognised that women have a right to express their requirements as fa r as lovemaking isconcerned. and that this does not usually entail just being banged into from behind with maximum penetration. It has been well established that orgasms of mammoth proportions can be produced from cUtoral stimulation. without any need for penetration by a penis at aU. Was there any clitoral stimulation during the experiments you quote? If

not, how long did it take before these women reached orgasm, as I should think it would be longer than most men could manage.

One of the patients, a woman, had been depressed for thrt'e months. 1he drug cured her problem, but s he asked if !Ike could be allowed to continue using it since she enjoyed the side effect so much. She had even found she could experi\'nce an orgasm by deliberate yawning. Another patient, a male, was also highly satisfied both with the drug's clinical dft.'Ctiveness and its side effect. He asked to continue taking the drug, solving the 'awkward and embarrassing' problem of repeated spontam.'Ous climaxes by wearing a condom all day. Apparently some 5 per cent of users of clomipramine reported the side effect.. which had also been observed in users of Prozac, although for the majority the ability to orgasm was inhibited by these drugs. One writer suggested that the effect, if it became widespread, could have had inter1!SHng social consequences.

Frozen stiff A frozen penis was the key to discovering the male impotence drug Viagra, according to three patent applications filed by Pfizer of Sandwich in Kent.lnjune 1990, Andrew Bell, David Brown and Nicholas Terrett described a range of pyrazolcr pyrimidinones that relieved angina and high blood pressure by inhibiting an enzyme called phosphodiesterase. Three years later. Terrett and Peter Ellis tested the drug on a detached frozen human penis. They found it inhibited a similar enzyme in tht' corpus cavemosurn tissue. When this tissue becomes engorged with blood it produces an erection. In a June 1997 patent, Peter Dunn and Albert Wood d.lscovered a better way 01 making the drug which was to become Vtagra.

Hydrogen sulphide (H.S) causes l'f'eClions in rats and may one day provide an alternative to Viagra for men. The penis is packed with spongy tissue that produces an erection when it fiUs w ith blood. Nitric oxide (NO) helps relax the walls of arteries that supply the penis, allowing extra blood to flow in. Viagra works by blocking an enzyme that destroys NO. In 2009, HaS had been shown to relax the walls of major blood vessels too. Giuseppe Cirino at the University of Naples Federico II in Italy and his coUeagues found enzymes that product' H.S in human penile tissue. lnjccting this tissue with H.S dilatoo the blood vessels, while injecting it into the penises ot Ih'e rats produced eTl!Clions.

In 2(0), psychologists at the University of Glasgow, UK, published iI study in which they asked heterosexual students in campus bars and cafes whether they had been dnnking. and then got them to rate photos of people for attractiveness. While the results supported the beer goggles theory, another explanation is thai regular drinkers tend to have personality traits that mean they find people more i1 ttrilctiVC, whether or not th£>y are under the influence of alcohol at the ti.Jne.

:The little shock that's too much for a sperm in 1990, a contraceptive which worked by eiectTocuting spenn was developed m the US. it had already been successfully tested in baboons. The device, similar to a tiny heart pacemaker, consisted of a lithium/iodirle battery - which was half a centimetre long and as thick as a cotton bud - and two electrodes. The plastic cylindrical battery was placed in the cervix and is anchored by two plastic lugs. The 2.S.VOIt battery generated a conslantclectrical cu,rrent of 50 microamps. This was conducted across the cervix by mucus or seminal fluid, irnmobilising sperm in three to four minutes, according to researchers a t the Women's Medical Pavilion in New York who developed the device. They believed the current would prevent the sperm passing through the cervix and fertilising the ovum: their in vitro studies showed that 1.00 per cent of sperm were stopped in their tracks by this level of rurrent, and studles in baboons seemed to back up the findings. The batteries were a modified form of a pacemaker. However, while a pacemaker lasts for up to ten years, the contraceptive baHeries would run oul after a year.

But research conduc~ in 2(0) had even better news for young men; frequent self-pleasuring could protl.'d: against the most common l.ind of cancer. A team in Australia led by Graham Giles of The Cancer Council Victoria in Melbourne asked 1.0 ']9 men with prostate cancer to fi ll in a questionnaire detailing their sexual habits, and compared their responses with those of 1.259 healthy men of the same age. The teilIT\ concluded that the more men ejaculated between the ages of 20 and ,)0, the less likely they were to develop prostate cancer. The protective effect was greatest while men were in their twenties: those who had ejaculated

LoVe. sex and all that swff 159

more than five times per week in their twenties, for instance, were one-third less likely to develop aggressive prostate cancer later in life. The results contradicted those of previous studies, which !>uggested that having had many sexual partners, or a high trt!quency of sexual activity, increased the risk of prostate cancer by up to 40 percent. The leey difference was that these earlier studies defined sexual activity as sexual intercourse, whereas the more recent study focused on the number of C'f aculations, whether or not intercourse was involved . The leam speru.iated that infections-caused by intermUl'S(' may increase the risk of prostate cancer. 'Had We been able to remove ejaculations associated with sexual intercourse, there should have been an even stronger prote(:tive effect of other I.iaculations,' they suggested. 'Men ha.ve trulny wOIYs of using thcir prostate which do not involve women or other men,' Giles added. But why should ejaculating more often cut the risk of prostate cancer? The team speculated that ejaculation prevents carcinogens building up in the gland. The prostate. together with the seminal vesicles, secretes the bulk of the Ouid in semen, which is rich in substances such as potassium, zinc, fructose and citric acid . Generating the fluid involves concentrating these components from the bloodstream up to Iioo-fold - and this could be where the trouble starts.

~ Frequent ejaculation may protect

against cancer Frequent sexual intercourse and masturbation could prota"t men against a common form of cancer, suggested a 2004 study or the issue. The US study, which foUowed nearly JOPOO men over eight years, showed that those w ho ejaculated most frequently were significantly 1($8 like1y to gct prostate cancer. The results backed. the fmdings of the Australian study dted above which asserted tha t masturbation was good fO'l" men. In the US srudy, the group with the highest lifetime averageofejaculation - 21 times per month-were a third less likely to develop the cancer than the reference group, who ejaculated four to seven times a month. MJchaeJ Leitzmann, at the National Cancer Institute in Bethesda, Maryland, and coUeagues set out to test a long-twld theory that suggested the opposite - that a higher ejaculation rate raises the risk of prostate cancer. The good news is it is not related to an increased risk.' he said. In fact, it 'may be associated with a lower risk'. 11 goes a long way to confirm the findings from our recent case-control study,' said Graham Giles, who led the Australian stud y; He praised the study's large size-including about

1500 cases of prostate cancer. Furthermore, it was the first study to begin by foUowing thousands of healthy men.

Bad guys really do get the most girls Nice guys already knew it, and in 2008 tv.·o studies confirmed it: bad boys get the most girls. The finding may help explain why a nasty suite of antisocial personality traits known as the 'dark triad ' persists in the. human population, despite their potenllally grave rulturaJ costs.

The traits are the seU-obsession of narcissism; the impulsive, thrill-seeking and callous behaviour of psychopaths;

and the dl'Ct?llful and exploitative nature of Machiavellianism. At their extreme, these tTa.its would be highly detrimental for life in traditional human societies. People with these personalities risk being shunned by others and shut out o f relationships, leaving them without a mate, hungry and vulnerable to predators. But being just slightly evil could have an upside; a prolific sex life, according to Peter Jonason al New Mexico State University in Las Cruces. 'We have BOrne evidence that the three hails are really the same thing and may represent a successful evolutionary strategy.' Jonason and his colleagues subjected 200 college students to personality tests-designed to rank them foreach of the dark triad traits. They also asked about their attitudes to 5elCuai relationships and about their sex hves, including how many !"'rtnel'S they'd had and whether they were seeking brief affalrs. High 'dark triad' scorers are more likely tn try tn poach othl!l' people's partners for a brief affair. The study found that those who scored higher on the dark triad personality traits tended to have more !",rmers and a greater desire for short·tenn relationships. But the correlation only held in

ma.les. Jilmes Bond epitomises this set of traits, Jonason said. ' He's clearly disagreeable, very extroverted and likes trying new things - killing people, new women.' Just as Bond seduces woman alter woman. people with dark triad traits may be more successful with a quantity.-style or shotgun approach to reproduction, even if they don't stick around for parenting. The strategy seems to have worked. We still have these traits: Jonason said. This observation seemed to hold across cultures. But questions remained as to its effectiveness. They still have to explain why it hasn't spread to everyone,' sa id Matthew Kelll!l' of the University of Colorado in Bou.lder. 'There must be some cost of the traits.' One possibility, both Keller and Jonason suggested, is that the strategy is most sue-

Unlver.>ity discovered thai male members of thai Specie. truly iU't' nol fussy. When placed in a room with a lifelikt' model of a female turkey, the birds mated with it as eagerly as they would the real thing. Intrigued by this observation, Schein and Hale embarked on a series of experiments todetennine the minimwn stimul~ it takes to excite a male turkey. involved removing parts from the turkey model one by one until the male bird eventually lost interest. TaD, feet and wings-Schein and Hale remov«J them all, but still the clueless bird waddled up to the model, ~ out an amorous gobble, and tried to do his thing. Finally,only a head on a stick remained. The male turkey was still keen. In fact, it preferred a head on a stick to a l'eadless body. The researchers speculated that the males' head fixation stemmed from the mechanics of turkey mating. When a male turkey mounts a female, he is so much larger than her that he covers her completely, except for her head. Therefore, they suggested, it is her head that serves as his focus of erotic attention. Schein and Hale then went on to investigate how minimal they could make the head before it failed to excite the turkey. lhey discovered that a freshly severed head on a stick worked best. Next in order of preference was a dried-out male head, followed by a two-year-old 'discolored. withered, and hard' female head. Last place went 10 a plain balsa wood head, but even that elicited a sexual response. They published their results in 1965 in a book called SaRlla 8tJvztJior. Before we humans snigger at the sexual predilections of turkeys, we should remember that our species stands al the sumO'l,/.I of the bestial pyramid of the perverse.

Double the fun Male lizards and snakes have to make a choice when they male; which penis shouJd they use? They have two, One is (onnccted. to their righl testis, and one to their left. In lCJ90, IWO biologists &om the US found thai some lizards alternate their penises when each is depleted. of sperm. In this way, they maxi~ their chance of fe rtilising a female. Richard 'rorkaz and Joseph Slowinski of Miami University studied the lit.ard Ano/u CIllUiintnSis. They found that the penis a lizard used depended on which they had used last time they mated, and how long ago they had last used it. Torkaz and Slowinski believed that such behaviour could be explained by 'sperm competition'. Zoologists have real· tsed. that competition for a female's favour does not simply involve fights among males or displays o f bright plwnage; it DIO continue inside the female's reproductive tract as sperms compete to be first to the egg. In response to such sperm competition, males of some species d eveloped sperm that formed into a hard plug, blocking the way for the sperm of any other males. In other species. males produced a lot of sperm, so that theSe oumumbered and swamped the opposition. However, keeping up a high level of sperm production can be a problem. If successive copuJations foUowed on too quickly from one another, this could resul t in the nwnber of sperm in the ejaculate dropping sharply. By alternating their penises, lizards of A. CDrolinOlSis may overcome this problem. Torkaz and Slowinski found lhat males alternated the use of their right and left pmises only if one copuJation {allowed less than 24 hours after another. If

168

HowtoMake~Toffl~do

the interval between copulations was longer, then they used the same penis. The biologists carried out an experiment in which they prevented penisaitemation. Theydid this by taping over one half of a male's cloacal vent, through which the penis protrudes when aroused. This stopped the animal from using the prois on thai side. The biologists found that males which were forced to reuse the same penis within 24 hours transferred fewer sperm in the later copulations. However, the researchers found no such drop in the numbers of speml when sucCt!ssive copulations were as long as 72 hours apart. In this siruation, they said, the sperm duct had time to be restocked with sperm. According to Torkaz and Slowinski. their research demonstrated that the lizards adjusted their behaviour in response to sperm competition, using thei r penises alternately to ensure that maximum sperm transfer was kepi up, even if the gap between copulations was short.

:'!¥ Big attraction Few birds have penises, but the Argentine lake duck Oxyura vittntn is one sizeable exception. Its corkscrew-shaped member was thought to be about 20 centimetres long - haJj the duck's body length. But in 2001, Kevin Md:racken of the University of Alaska found one aroused specimen whose penis was hanging out of the body sac where il usually resided. It measured a whopping 42.5 centimetres. This is the first record of the penis "hanging out" in its natural form: said McCracken. He suggested thai this highly promiscuous bird displayed its penis to attract females, which oUght explain why evolution has favoured length.

~ Exhibitionist spiny anteater reveals

bizarre penis In 2DO']. the bizarre sex Ufe of the spiny anteater was exposed when it was discovered that the male ejaculates using only one haJi of its penis. These fincJjngs about the creature's sex life may seem salacious but they could help shed light on an evolutionary mystery. It seems that the way the mammaJ ejaculates is similar to the way reptiles do - by shutting down one side of its penis before secreting semen from the other side. Reptiles have a pair of male members mlled hemipenes for sex. and they use only one of the two during eadl act of copulation (see page

'67)· The spiny anteater (Tachyglossus lICufaztus), also known as the short-beaked echidna.. is a primitive mammal found in Australia and New Guinea. Like the platypus, it is a monotreme, laying eggs instead of bearing live young. Monotremes have many features in common with reptiles, and the hope is that by studying them, scientists may find dues as to how mammals evolved. The spiny anteater, however, is notoriously difficult to observe in the wild and shows hH1e enthusiasm for breedmg in capbVlty, so, pnor to 20tYJ, nobody had managed to observe them ejaculate.

Fortunately. Steve Johnston of the University of Queensland in Galton, Australia, and his colleagues inherited a m<\le spiny anteater that was not so shy. The creature had been 'retired' from a zoo because it produced an erection when being handled at public viewing sessions, bemusing its vh;itors. By filming this animal, the researchers were able to describe the unique spiny anteater erection and ejaculation behaviour for the first time. The spiny anteater 's four-headed phaUus had been puzzling scientists. 'When we tried to collect semen by eledrically stimulated ejaculation before, not only did we oot get a single drop, but the whole penis swelJed up to a four-headed monster thai wouldn't fit the female reproductive tract, which has only two brandles,' said Johnston. 'Now we know that duri..ng a nor.tJ\ill erection, two he;Jris g('t shut down and the other two fit.' The heads used are swapped each time the mammal has sex. The evolutionary significance of one-sided ejaculation was unknown, but may playa role in sperm competition where sperm from many males may compete to fertilise an egg. Indeed, in the spiny anteater, up to 11 males may form a queue behind one female to copu1ate with her. lhe researchers also observed that hundreds of sperm team up to form bundJes thai swim much faster than individual speno in the spiny anteater's semen - .mother possible ad"ptation for sperm competition. 'We can now study echidna sperm much better, which should offer fascinating insights into the evolution of mammals: said Russell Jones from the University of Newcastle in New South Wales, who first dissected spE'rm bundles from dead echidna in the lCj80s.

'f): Why a big horn gives beetles a tiny organ Ra pid metamorphosis may explain why beetle species are numerous enough to overwhelm almost any other creature on Earth. The superfast evolution of the male dung beetle's penis to wildly differing sizes in the same species could mean that new species appear within a few years rather than over millennia. In 2008, Annin Mocze:k from lndiana University, BloomIngton, and colleagues studied four popuJations of one species of homed beetles in Eastern and Western Australia.. Italy and the US. The most striking difference was between beetles in Western Australia, which had small horns and big genitals. and those in the US, which had the complete opposite. Th~ variation in genita l size between these two pupulations was as pronounced as that between ten other species in countries across Asia, Ewope. and South America. Organs developing within the pupa must compete for a limited supply of nutrients. So if one organ grows bigger, another is stunted. Thus, males with large horns tend to have smaller genitals, and vice versa. Strong male bt.'etles use their horns to fight for females, but weaker males prefer to sneak off to mate while competitors are fighting. Which strategy works best depends on the size of the population. In those with more females, fighting is most successful, and big-homed beetlL'S win most mates. But when there are nol enough females, fi ghting isoften fruitless. 50 evolution favours beetles with smaller horns but cunning lactiCS.

Because bL-etles with genitals of differenl sizes cannot mate, Moczek thought the four populations might soon split into di5t:iru:t species. ' It's unprecedented that 50 years would be long enough to generate variation nonnally only found in

~ Hen night A 1958 report from Germany threw an unexpected sidelight on the behaviour of hens. The agricultural research institute at Wiirzburg had been studying what, if any, were the harmful effects of wines produced from hybrid grapes. Gennany. like France and Switzerland, was plagued with a sizeable output of wine of extremely low quality and dubious potability. In the experiments hens, spiders and goldfis h were all used, and the hens in particular consumed astounding quantities of wine. They were divided into three groups, the controls being given water only and the others pure wine and hybrid wine respectively. Each hen was given half a pint of liquid a day. [ncredibly. 16 hens got through 600 pints of red wine in four months. seemingly in radiant health. These 16 did not, however. include any of the hens that drank hybrid wine these died early in the stud y. The fate of the spiders and goldfish was not disclosed.

:'l: Not tonight Wh ile making a 'standard observation of sexual bcltavioUI' in 1972, Ronald Barfield and Lynette Geyer noticed that the male of the species under study sang an ultrasonic song after his ejaculation. Following up Ihis chance observation.. the Rutgers University biologists found thai this post~aculatory ultrasonic chant - which appeared to correlate with the indivldu· aI's contented stertorous breathing - was rommon to all the males they studied. The duration of the song. and the behaviour or the female partners during its performance, suggested that it functioned as a desist-contact - or 'leave me atOIle' signal, while the male recovered for another bout of sexplay. The species involved in the experiments was the rat, whose sexual behaviour, according to the authors, had bet.."fl 'exhaustively studied'. A series of mount bouts led to intromission and subsequent ejaculation, followed by a refractory period during which the male recuperntcd. The female hopped, darted about and wiggled her ears during copulation. but in the male's refractory period - when he usually either stretched out for a doze on the floor or groomed quietly - she refrained from such provocative behaviour Barfield and Geyer showed that for at least three-quarters of the interval between copulatory bouts the male emitted a series of calls at 22 kilohertz, apparently arising from the long exhalations of its languid breathing. Since the length of this calling period coincided neatly with the time during which the male was quire incapable of perfonning again, and since

the behaviour of the female changed during this period too, the researchers suggested that the call conveyed a positive 'I'm out of action' type of message to the female. Their conclusion was reinforred by the [act thai a :u-kilo-hertz call was also characteristic of mall!S that have been roundly defeated in a fight, and in females who were attempting to resist the mount!! of overly attenthe maJes. Perhaps, Barfield and Geyer suggested, the call generally reflected a state of social withdrawal; that '.u kilohertz. isa basic '"'carrier frequency" for signals denoting <;tates of contact 'YOidanu" It would be jnte~lm!l; to know what would happen if , r:ll colony was played continuous recordings of these anlbocial signals.

Nuclear digging on trial i'roject Gasbuggy, the world's first commercially sponsol\.'CJ nuclear explosion. is scheduled to take place on 14 November 1¢7 on a lonely plateau in northern New Mexico. Gasbuggy (~the most advanc.?d test vet in the US Atomic Energy Comrnission's Plowshare programme, which aims to find peaceful USE'S fat nuclear explosions. Its objecl is to determine how l'ffectively nUdl::3r explosions can release natural gas from IIl)rmcilly impermeable rock.

The blast is expected to create 3 'chimney' of broken rock. greatly increasing the flow of natural gas through a well to the surface The most troublesome problem is radioactivity - nol from the venting of the e>.-piosion, but from the isotopes that will be c~ated in the undergrOllOd chimney. When the explosive goes off. it will produce a bubble tOo fet'l in diilml'let. As the cavity cools., its ceiling will cr>llapse to create the cltimney Most of the radioisotopes produced by the blasl will disappear quickly, but three will remain - iooine-131, krYPtoO-tl5 ilnJ tritium. The iodine will decay to a ~ta.ble form wjlhjn months and the krypton may be trapped in the molt~ rock that flows to the bottom 01 the chimney, but the bitiwn will linger on.

The plans envisa~e a locomotive 35 metres ton~ and .3 metres wide, wluch will weigh approximCondary safety devices. A further weight saving is also possible if the deSigners elect to use mechanical-hydraulic transmission instead of the heavier electrical type. The reactor will be a Babcock and Wilco)! design that is )05 millim~tres long. Instruments will be Installed U1 the locomotive to detect dnd measure radioactive t!manatlon from the power plant. TIle crew will be provided with special clothing, and the driving compartment wiJI be insulated against radiation, noise and heat. The running costs of the locomotive are e.'(pected to be low£'r than the cost ot operatmg a steam locomollve in Western Gennany but somewhat higher than an electric one.

No information is yet available about when construction will begin nor when th.. new design is likdy to come mto passenger service.
