Sperm whales are among the biggest living things on the planet and, surprisingly for these gentle giants, once must have been among the most fearsome. Palaeontologists working in Peru have uncovered the remains of an extinct long lost relative of today’s sperm whale that had 30-40 cm long teeth in both jaws (the modern form has much smaller teeth in the lower jaw only). With jaws more closely resembling those of a killer whale than its thrust/suction feeding relative, scientists believe the newly named Leviathan melvillei was a 15 m long hunter of large prey, probably other whales. Its size, jaws and undoubted intelligence would have made this marine monster more than a match for the giant shark Megalodon with which it shared its home (Science [article], Nature [paper]).
Sperm whales are still the largest animal ever to have teeth, but today their diet consists mostly of squid – including the infamous giant squid – and therein lies a problem. Whereas most land dwelling creatures live on plant material, or some juicy meaty derivative thereof, and hence are essentially “carbon-neutral”, marine animals from penguins to whales feast upon carbon that was probably sequestered in the oceans hundreds if not thousands of years ago, or has weathered out of rocks that are millions of years old. One upshot of this is that carbon dating is notoriously inaccurate on marine organisms, what scientists call the “reservoir effect”, another is that unlike water breathers such as fish, who return this carbon to the oceans, air breathing animals like whales will release this carbon to the atmosphere as CO2 and so contribute to global warming. However in new research published by the Royal Society of London, researchers have calculated that whales have actually offset their carbon emissions with emissions of another kind. Whale poop is iron rich and comparatively liquid, hence returns the excess iron in the whale’s diet back to the oceans in a form that is readily usable by phytoplankton. The team, led by Trish Lavery of Flinders University in Australia, estimate that sperm whales are responsible for removing 200,000 more tonnes of carbon from the atmosphere annually than they actually emit (Royal Society).
But it’s not all good news for the tree-huggers for while whales might be a boon in the fight against climate change, their free-range, organic farming practices of preference are almost certainly not. In a paper published by the National Academy of Sciences, Jennifer Burney of Stanford University and her colleagues have found that intensive farming is by far the most land and carbon efficient method of agriculture. Because agricultural land use is a major contributor to global warming, increasing the yields from farmland, and thereby reducing the amount of land farmed, strongly outweighed the extra carbon emissions of the intensive farming needed to achieve this. Doing the sums on farm outputs since 1961, the team found that increased yields have produced the same as cultivating an additional area the size of Russia at 1961 levels, which would have led to the release of 590 billion more tonnes of CO2, equal to about a third of all man-made emissions since the industrial revolution (PNAS).
And modern farming may be coming to our rescue in another way, as a source of cheap batteries. Almost since Ben Franklin gave up kite-flying, kids in schools the world over have been making batteries out of apples or a potatoes. Now a trio of researchers from the Hebrew University of Jerusalem, led by Alex Goldberg, have found a way to turn these vegetable power sources from classroom curiosities into a viable product. What’s more amazing is the method they discovered to generate a tenfold increase the output of their potato power-pack, they boil the potato first. How did no-one think of this before (AIP)?
Another new idea, albeit a less welcome one, is that one should prosecute scientists for not knowing everything. At least that seems to be the approach taken by the public prosecutors of the Italian city of L’Aquilla, which last year was hit unexpectedly by an earthquake that killed over 300 people and injured 1600 more. The defendants include the head of Italy’s National Institute of Geophysics and the director of the National Earthquake Center along with four other equally prominent scientists and Bernardo De Bernardinis then deputy head of the Civil Protection Agency, who together are looking at being tried for manslaughter for not alerting the population to the imminent disaster at a meeting held one week before the quake struck. It was Bernardinis, a government official, who claimed in a press conference held immediately after the meeting that the scientists had said there was “no danger”, despite the minutes of the meeting clearly showing that at no time was the chance of a major shock ever ruled out (Nature).
President Obama’s recent fall in approval rating may have an unusual cause, he may possibly be too thin. In a recent study by Elizabeth Miller of the University of Missouri, voters prefer their male politicians to be portly, while women representatives should be more wasp-waisted. In an experiment involving 120 volunteers, people were asked to assess fictitious male and female candidates from a brief bio and a picture, crucially two pictures of each candidate were used, a natural one and one manipulated to portray the person as overweight. People shown the heavier male scored him an average 10% higher for reliability, honesty, dependability and inspiration than his thinner doppelganger, but this relationship was reversed in the woman candidate. In the journal Obesity, Miller puts this down to societal expectation and stereotyping (Telegraph).
Social pressure also crops up in explaining another finding this week, this one by Meridith Young of McMaster University in Ontario, that what single women eat depends a lot on whom they are eating with. After covertly monitoring the canteen behaviour of 470 undergraduates, Young found that women significantly lowered their calorie intake when sat with men compared with all women groups. Moreover, the more men a woman sat with, the less on average she consumed. In the journal Appetite, she puts the discrepancy down to women unconsciously advertising themselves to men, adding "the salad leaves are meant to say, I'm pretty, I'm attractive, I take care of myself" (Guardian).
Of course, we all know what men really like in a woman; that she not appear too powerful. Or so says a study by Brian Meier and Sarah Dionne of Gettysburg College in Pennsylvania. In the study, eighty 19 year-olds were asked to rate the attractiveness of a number of images presented in random order, some of which would be repeated. In fact the subjects saw each image twice, once near the top of the screen and once low down. The researchers found that men rated women 1.8% more attractive when observed near the bottom, and women found men 1.5% better looking when higher up. They suggest that their findings might explain why men are taller than their women partners more frequently than would be expected by chance (Times of India).
As to what women really like in men, perhaps not being British should be somewhere on the list. After champagne controversially lost out to an English wine earlier this week, French scientists have hit back at British research that concluded that the mythical “G-spot” did not exist. “Of course it exists,” say French gynaecologists, “you just can’t find it!” The original study by King’s College in London looked at over 900 pairs of identical or non-identical twins in the expectation that the identical siblings should both report having a G-spot more frequently than the others, they did not. The French however claim their cross-channel colleagues have got the wrong end of the speculum, “It is not a question of genetics but of use," said one (Telegraph).
One of my college courses this year is called "Posthumanism in Science Fiction" (it actually counts towards the core classes needed to graduate). The instructor, Dan Dinello, used to work with Stephen Colbert back in the 1990s, and recently he decided to show the class one of the short films he made with Colbert, a strange dark comedy called Shock Asylum. Like everything else, it happened to be on YouTube (though this version is shorter than the one I saw), so enjoy:
I wonder what would have happened had Dr. Sherman's plan been put into action? It would certainly relieve stress -- and provide a much more realistic view of the world -- if we were all taught from day one to accept our mediocrity. Reported in the Newark Advocate, Dec. 1, 1936:
Training for Failure
It seems that parents are wrong in counseling their youngsters to study hard and aim for the presidency.
Anyway, Dr. Mandel Sherman, mental hygiene specialist at the University of Chicago, advises that young people be trained to become failures, in the ordinary sense of the word.
"Our educational system is suffering from an overdose of success stories," he contends. "One person in 10 is neurotic, one in 22 insane today because we train only for success. And only a few can be successful from a material standpoint."
Youth perhaps should be taught that a successful life need not include fame and riches. But history, studded with instances of handicapped youngsters who fought their way to success, indicates that it would be difficult to get the younger generation to bow its head to the inevitability of failure.
Paradoxical undressing is a term for a phenomenon frequently seen in cases of lethal hypothermia. Shortly before death, the person will remove all their clothes, as if they were burning up, when in fact they are freezing. Because of this, people who have frozen to death are often found naked and are misidentified as victims of a violent crime.
The reason for this paradoxical behaviour seems to be the effect of a cold-induced paralysis of the nerves in the vessel walls, which leads to a vasodilatation, giving a feeling of warmth. Another theory proposes that the reflex vasoconstriction, which happens in the first stage of hypothermia leads to paralysis of the vasomotor center giving rise to the sensation that the body temperature is higher than it really is and in a paradox reaction the person undresses.
But wait! It gets even weirder. Once they've undressed, the dying person will frequently try to crawl into a small, enclosed space. For which reason, victims of hypothermia are often found naked, squeezed into cupboards or beneath beds. This is called Terminal Burrowing Behavior. Again from Rothschild and Schneider:
In 20% of our cases of death due to hypothermia the bodies were found in a position, which at first induced the suspicion of an attempt to hide the body. But after all our examinations together with the police investigations it was clear that no other person was involved. Obviously the strange positions in which the bodies had been found, were the result of a (pre-)terminal behaviour, which - for lack of comparable descriptions in the literature - we have called "terminal burrowing behaviour". The discovery positions always gave the impression of a protective burrow-like or cave-like situation, as the bodies were found under the bed, behind the wardrobe, in a shelf etc.. The clothes of the bodies were always strewn on the ground in front of the final position, sometimes forming a trail. In every case the paradoxical undressing had obviously happened before this self-protective "burrowing behaviour". This is sustained by the fact that the removed clothing was never found at the final position where the body was found, and some of the victims due to cooling had obviously been crawling around. In most cases the final position in which the bodies were found could only be reached by crawling on all fours or flat on the body, resulting in abrasions to the knees, elbows, etc. This crawling to the final position seems to have happened after undressing as there were abrasions to the skin but no damage to the corresponding parts of the removed clothing.
The body of a 91-year-old man was found beneath a bed in the corner of a shed. The man had burrowed there.
I came across a description of this experiment in an old newspaper (Reno Evening Gazette, Sep 8, 1941) and have never found any other references to it. The experiment was conducted by British psychologists who wanted to find out if "civilian populations can be made immune, through familiarity, to fear caused by air raid noises." The methodological problems with the design of the experiment are obvious, but it's interesting that it was conducted nevertheless. The details follow:
The London experiment consisted of herding workers, children and bomb-shocked neurotics into underground vaults and there subjecting them to an 'artificial blitz bombing.'
Sound effects used in the test were recordings made during one of London's worst air raids last year, amplified to simulate the real thing. An Associated Press writer who witnessed the experiment reported:
"The sounds swelled in the dark vault. The guns kept banging. Then big bombs burst. The guns kept up. More bombs. Then the crackle of flames. Next clanging fire engines added their noise, the other sounds continuing."
According to the reporter, the subjects stood the test very well: 'No one was crying out. A flashlight swung around the room, revealing drawn faces and frightened eyes. But no one was swooning. The experimenters stepped up the amplification.'
The British psychologists responsible for the experiment were reported delighted with the results. They said it proved their theory that whole populations could be exposed to 'artificial blitzkriegs' and thus rendered immune to fear during air raids.
Hugmachine.org offers complete instructions on how to build your very own, low-cost hug machine. For those times when you need to feel the comforting press of two mattresses around you.
The Hug Machine was invented by Temple Grandin as a way to treat her autism. From Wikipedia:
The idea for the hug machine was devised during a visit to her aunt's Colorado ranch, where she noted the way cattle were vaccinated while confined in a squeeze chute, and how some of the cattle immediately calmed down after pressure was administered. She realized the deep pressure from the chute had a calming effect, and decided that might well settle down her own hypersensitivity. Whereas psychologists at her high school sought to confiscate her prototype hug machine, her science teacher encouraged her to determine just why it helped resolve her anxiety and sensory issues.
