How statistics lost their power – and why we should fear what comes next | William Davies
The ability of statistics to accurately represent the world is declining. In its wake, a new age of big data controlled by private companies is taking over – and putting democracy in perilIn theory, statistics should help settle arguments. They ought to provide stable reference points that everyone – no matter what their politics – can agree on. Yet in recent years, divergent levels of trust in statistics has become one of the key schisms that have opened up in western liberal democracies. Shortly before the November presidential election, a study in the US discovered that 68% of Trump supporters distrusted the economic data published by the federal government. In the UK, a research project by Cambridge University and YouGov looking at conspiracy theories discovered that 55% of the population believes that the government “is hiding the truth about the number of immigrants living here”.Rather than diffusing controversy and polarisation, it seems as if statistics are actually stoking them. Antipathy to statistics has become one of the hallmarks of the populist right, with statisticians and economists chief among the various “experts” that were ostensibly rejected by voters in 2016. Not only are statistics viewed by many as untrustworthy, there appears to be something almost insulting or arrogant about them. Reducing social and economic issues to numerical aggregates and averages seems to violate some people’s sense of political decency. Continue reading...

$460m pledged for vaccine initiative aimed at preventing global epidemics
Lassa, Mers and Nipah will be first diseases targeted by programme announced at Davos by coalition of governments, philanthropists and businessA coalition of governments, philanthropists and business is pledging to put money and effort into making vaccines to stop the spread of diseases that could threaten mankind – and to prevent another outbreak as devastating as the Ebola epidemic.At the World Economic Forum in Davos, the Norwegian, Japanese and German governments, the Wellcome Trust and the Gates Foundation announced they were putting in $460 million – half of what is needed for the first five years of the initiative. Three diseases will initially be targeted: Lassa, Mers and Nipah. All three are caused by viruses that have come from animals to infect humans and could trigger dangerous global epidemics.

The Guardian view on Trump and global warming: the right fight | Editorial
The president-elect should understand that America needs to shoulder global responsibilities, and that in doing so America will benefit by owning the technologies of the futureOn climate change, like so many other things, the world is going one way and Donald Trump is going the other. On Twitter the president-elect has claimed manmade global warming was a hoax invented by China to increase its trade surplus with the US. However, for most Americans, like most other people on the globe, daily life is increasingly impacted by extreme weather. In 2016, for the third year running, the world exceeded the previous record temperature. A remarkable 16 of the 17 hottest years on record have been this century, which scientists attribute to human activities.President Obama did much to roll back the pre-enlightenment approach to climate science that had polluted political discourse in America – giving global warming top billing during his second term, and even calling it an immediate threat to national security. His parting shot was to send $500m to prop up the Paris international accord to limit greenhouse gas emissions. Mr Trump vowed to renege on the Paris agreement and said he would cancel further payments. Continue reading...
Over half of world's wild primate species face extinction, report reveals
Researchers warn of approaching ‘major extinction event’ if action is not taken to protect around 300 species, including gorillas, chimps, lemurs and lorisesMore than half of the world’s apes, monkeys, lemurs and lorises are now threatened with extinction as agriculture and industrial activities destroy forest habitats and the animals’ populations are hit by hunting and trade.In the most bleak assessment of primates to date, conservationists found that 60% of the wild species are on course to die out, with three quarters already in steady decline. The report casts doubt on the future of about 300 primate species, including gorillas, chimps, gibbons, marmosets, tarsiers, lemurs and lorises.
The secret of Namibia's 'fairy circles' may be explained at last
Using computer models, ecologists think they have finally hit upon the reason for the strange polka dot patches scattered across the Namib desertThe marks on the ground in the Namib desert resemble a vast sheet of polka dots, or to the less romantic observer, perhaps a bad case of chickenpox.In local myths, the bare, red circles fringed with grass are footprints of the gods, or patches of land once poisoned by the breath of a subterranean dragon. But even among scientists, who strive for more convincing theories, the curious, repetitive patterns have proved hard to explain. Continue reading...
2016 hottest year ever recorded – and scientists say human activity to blame
• Final data confirms record-breaking temperatures for third year in a row• Earth has not been this warm for 115,000 years2016 was the hottest year on record, setting a new high for the third year in a row, with scientists firmly putting the blame on human activities that drive climate change.The final data for 2016 was released on Wednesday by the three key agencies – the UK Met Office and Nasa and Noaa in the US – and showed 16 of the 17 hottest years on record have been this century.

Palaeontologists solve an ancient tentacled mystery | Susannah Lydon
Exceptionally preserved fossils have enabled researchers to place a tricky group of extinct marine animals on the tree of lifeThere are some fossils it’s difficult to get enthusiastic about. Don’t get me wrong: as someone whose PhD focussed on the fossil equivalent of tea-leaves, my threshold for getting excited is a lot lower than most people. But when you’re studying undergraduate palaeontology there’s an awful lot of extinct shelly things you must learn about. Contrary to the popular conception of what palaeontologists study (dinosaurs!), marine invertebrates with mineralised hard parts are the mainstay of working with fossils.There are some familiar groups that, although they are extinct, we do know a fair bit about. Trilobites and ammonites fall into this category: we have a good sense of their evolution and diversity through time, and have inferred a fair bit about their biology. There are other groups that are less well understood. We’ve got lots of shells, but we don’t know what the soft bits of the animal looked like, and we don’t know where they fit on the tree of life. In short, they are a bit of an embarrassment. Luckily, there are palaeontologists who rise to the challenge.
Testosterone Rex by Cordelia Fine review – the question of men’s and women’s brains
The psychologist provides more evidence that the inequality of the sexes in society is cultural not naturalCordelia Fine is an optimistic writer. In her two earlier books of popular neuroscience (A Mind of Its Own and Delusions of Gender), the psychologist established a reputation for exemplary clarity on complex topics, pleasing wit, feminist principle – and beneath it all, the animating faith that people can be improved through knowledge. Testosterone Rex starts with a quote from Chimamanda Ngozi Adichie’s We Should All Be Feminists that establishes the Fine approach perfectly: “But in addition to being angry, I am also hopeful, because I believe deeply in the ability of humans to make and remake themselves for the better.”“Testosterone Rex”, Fine’s target, is the name she gives to “that familiar, plausible, pervasive and powerful story of sex and society”, which holds that inequality of the sexes is natural, not cultural. After all, testosterone makes men tall, hairy and deep-voiced; it makes a certain superficial sense to imagine it also produces other characteristics we think of as masculine, such as leadership, violence and horniness. For example, neuroscientist Simon Baron-Cohen (the Alien to Fine’s Ripley in the dispute over brain sex) calls the hormone “that special substance”, and credits it with inducing all manner of adaptive qualities in those creatures fortunate enough to produce large amounts of it. T is the king. Continue reading...

Moon Express raises $20m for 2017 voyage to the moon
So, it’s the Germans who are to blame | Letters
The word “So”, used as a “Well, …” or “Um, …” at the start of a sentence (Letters, 16 January) has been current in America for quite some time.I guess it is another of many examples of US English usage that originated with German immigrants before travelling back over the Atlantic to us. It’s very common in German to begin a sentence with an “Also …” pronounced with the emphasis on the first syllable and meaning “Well, …”. Sometimes the meaning of a German-influenced word or phrase undergoes a subtle or even radical alteration on its way into the English language. The oddest example that I can think of is our use of “half two” to mean “half past two”. In German “halb zwei” is 1.30 not 2.30.

Red meat cancer link | Charges against Lula | Robots as people | Ring pull safety | Peanut butter on WeetabixNaomi Elster writes: “There isn’t currently any strong evidence that eating too much red meat causes cancer”, before noting that Cancer Research UK is a “reliable source … for advice and support” (The truth about cancer diets, G2, 16 January). However, responding to the WHO’s October 2015 International Agency for Research on Cancer report which classified red meat as “probably carcinogenic to humans”, Professor Tim Key, Cancer Research UK’s epidemiologist at the University of Oxford, said: “Cancer Research UK supports IARC’s decision that there’s strong enough evidence to classify … red meat as a probable cause of cancer.”
Gene Cernan obituary
American astronaut who was the last human being to walk on the moonAt 1.54pm on 11 December 1972, Gene Cernan piloted Challenger, Apollo 17’s lunar module, into the Taurus-Littrow valley, near the Sea of Serenity, on the surface of the moon. In later years Cernan, who has died aged 82, would describe the valley where he had landed accompanied by the geologist Jack Schmitt as “our own private little Camelot”.Three days later, having travelled to such locations as the Sculptured Hills, and the Van Serg and Sherlock craters, the astronauts prepared to leave. Cernan marked out his daughter Teresa’s initials in the dust, where they remain. Before climbing back into the lunar module, he paused and spoke to Mission Control back in Houston: “As we leave the moon at Taurus-Littrow, we leave as we came, and, God willing, as we shall return, with peace and hope for all mankind.” Continue reading...

What lies beneath: discovering surprising jewels in the North Sea
Not far from the mouth of the river Tyne, fabulously-coloured nudibranchs and corals can be spotted amongst rusting sunken shipsAs I finned alongside the bulky remnants of the ship’s boilers - three massive blocks of northern iron – the light had almost gone. The gently rusting masses were riddled with fire-tubes, each seemingly host to a wary crab. In some, the red eyes of a velvet swimming crab (Necora puber) reflected my light; in others edible crabs (Cancer pagurus) retreated from my gaze. Small prawns and a few well-camouflaged fish moved to avoid me, drab browns revealed as reds and oranges under my torch light. And there, on a piece of deck plate, covered by a bright red encrusting sponge, was one of the jewel-like animals I’d set out to capture on film. Continue reading...
Australia's bees and wasps revealed to be as dangerous as its snakes
More than half of deaths from bites and stings between 2000 and 2013 the result of anaphylactic shock, analysis showsOf all Australia’s venomous animals, bees and wasps pose the biggest threat to public health, causing more than twice the number of admissions to hospital as snake bites and the same number of deaths.The first national analysis of 13 years’ data on bites and stings from venomous creatures has found that just over one-third (33%) of almost 42,000 admissions were caused by bees and wasps, compared with 30% by spiders and 15% by snakes.

Eugene Cernan, last man to walk on moon, dies aged 82
Former astronaut was final person to leave footprints on lunar surface as commander of Apollo 17 in 1972The last man to walk on the moon, Eugene Cernan, has died at the age of 82. The American travelled into space three times, and became the 11th person to walk on the moon and the last to leave his footprints on its surface as commander of Apollo 17, the final manned lunar landing.His death was confirmed by Nasa in a statement on Twitter that read: “We are saddened by the loss of retired Nasa astronaut Gene Cernan, the last man to walk on the moon.”
Natural selection making 'education genes' rarer, says Icelandic study
Researchers say that while the effect corresponds to a small drop in IQ per decade, over centuries the impact could be profoundTempting as it may be, it would be wrong to claim that with each generation humans are becoming more stupid. As scientists are often so keen to point out, it is a bit more complicated than that.A study from Iceland is the latest to raise the prospect of a downwards spiral into imbecility. The research from deCODE, a genetics firm in Reykjavik, finds that groups of genes that predispose people to spend more years in education became a little rarer in the country from 1910 to 1975.

The seven faces of Donald Trump – a psychologist’s view
From the chin-jut to the zipped smile, we examine the president-elect’s signature facial expressions and what they tell us about himA great deal of Donald Trump’s political success can be put down to his body language and the unusual ways he uses his face. The first thing we notice about Trump’s facial expressions is the sheer variety. The second is their dramatic, often over-stated character. This was evident before and during the presidential election. While the other candidates – Hillary Clinton included – were struggling to appear likeable and restrained, Trump was busy performing grimaces that would not have looked out of place in Japanese Noh theatre. But what are Trump’s signature facial expressions, and what do they tell us about him? Continue reading...
Killer whales explain the mystery of the menopause
A study of the whales, one of only three species whose older females stop reproducing, claims competition between offspring may be the causeKiller whales and humans would seem to have little in common. We inhabit very different ecosystems, after all. Yet the two species share one unexpected biological attribute. Females of Orcinus orca and Homo sapiens both go through the menopause.It an extraordinary aspect of our development. In contrast to the vast majority of animals on our planet, women and female killer whales stop reproducing halfway through their lives. Only one other species – the short-finned pilot whale (Globicephala macrorhynchus) – behaves this way. Continue reading...

From the Observer archive: this week in 1920
The curse of illuminated advertisementsThe suppression of the large, illuminated, advertising signs throughout London was by far the most tolerable of war restrictions. There is no question that the blinding of these staring and superfluous vulgarities enhanced the nocturnal beauty. We dispensed most comfortably with them for five years. Why were they permitted to return? One, the most monstrous of its kind, can be seen by day across the river, chained to its tower, and threatening to blaze up any night. The rest of the tribe, with additions, are back. Their lights wink stupidly and flicker in an exasperatingly mechanical rhythm. The current unrolls and rolls up again a meaningless legend in strident colours, until the passer-by is almost provoked into a vow of abstinence from the products crudely heralded. The very glare of them and the inanity of their endless repetition are mesmeric. They assault tired eyes and harry the nerves of the home-going worker. They are blatant in their ugliness as they are blatant in defiance of the coal shortage. We are very far from being fanatical supporters of the sentimental argument commercial expansion has so often to meet. But commercial advertising must recognise its limits. A limit has been reached in this impudent desecration of some of our finest City-scapes. Continue reading...
Lab notes: killer mice and interspecies sex put the 'wild' in wildlife
Many people are afraid of mice, but these ones really take the (cheese) biscuit: a study designed to examine the predatory instinct in mice successfully used optogenetics to switch their killer instincts off and on at will. In a slightly more romantic(? maybe not) vein, a male snow monkey was observed attempting to mate with female sika deer in Japan. This is only the second recorded example of sexual relations between two distantly related species, and could be down to “mate deprivation”, say researchers. In more heartwarming news, scientists have studied the impact of babytalk on dogs, concluding that that puppies respond well to it, but older dogs are unmoved. It might also shed light on the way humans communicate with actual babies. And if animals aren’t your thing, don’t despair: there’s some exciting knot news as well! Chemists have broken a world record, creating tightest knot ever made – a microscopic circular triple helix built from a strand of atoms, which could make a whole new world of materials possible. And if even that’s knot (aha!) enough to banish the January blues, perhaps the possibility of rare thundersnow might interest you. This video explains it all AND contains one of the most excitable reactions to weather I’ve ever witnessed. In more serious news, medical and legal specialists have warned that recent breakthroughs in fertility procedures could lead to “embryo farming” on a massive scale and drive parents to have only “ideal” future children – and that we must start to plan for the potential impact on society now.

Trump's vaccine conspiracy theories are a threat to your children | Celine Goudner
Vaccines have been shown safe and effective. When he hints otherwise, the president-elect is gambling with young livesThis week, vaccine skeptic Robert F Kennedy Jr announced that he’d been nominated by President Elect Donald Trump to chair a commission on vaccine safety. A few hours later, the transition team issued a statement saying that that Trump was “exploring the possibility of forming a committee on autism”. Last summer, Trump met with Andrew Wakefield, who lost his medical license and was found to have produced fraudulent research linking vaccines to autism. Whether Trump is creating a commission on vaccine safety or autism, the message is clear. Trump is offering prominent support to the conspiracy theory that vaccines cause autism.The science on vaccines is very clear: they are safe and effective. Vaccines do not cause autism. It’s a waste of our tax dollars to rehash this issue yet again. Vaccines are one of the greatest triumphs of modern medicine. Let’s consider measles, just one of many vaccine-preventable diseases. Before 1963, when the measles vaccine became widely available, 3-4 million Americans got measles each year, of whom 48,000 were hospitalized, 4000 developed encephalitis resulting in long-term brain damage, and 4-500 died. The country’s population has almost doubled since that time. Continue reading...
Poisoned, shot and beaten: why cyanide alone may have failed to kill Rasputin
Theories around the death of Grigori Rasputin still abound 100 years after the event. We examine the scientific credibility of some of the claimsThe end of December marked the 100th anniversary of the death of Rasputin, the “mad monk of Russia”, or “lover of the Russian queen” if you believe the Boney M song, though you probably shouldn’t. While the song is undoubtedly a floor-filler, unsurprisingly it is not exactly a reliable historical account of Rasputin’s life.Grigori Yefimovich Rasputin, a mystic and spiritual healer born in Pokrovskoe in Siberia, wielded huge influence over the Russian royal family, particularly Alexandra, the Tsarina, who looked to the spiritual healer to cure her haemophiliac son, Alexei. The life of Rasputin was certainly pretty strange but it is the stories surrounding his death that are the strangest of all. Continue reading...

Knotty professors: chemists break world record to create tightest knot ever made
A microscopic circular triple helix built from a strand of atoms could make a whole new world of materials possibleIn a feat that breaks one of the most obscure world records in science, a team of chemists has created a microscopic circular triple helix, or put in more simple terms, the tightest knot ever made.Researchers in Manchester in the UK built the knot from a strand of atoms which curls around in a triple loop and crosses itself eight times. Made from 192 atoms linked in a chain, the knot is only two millionths of a millimetre wide – around 200,000 times thinner than a human hair.

Scientists use light to trigger killer instinct in mice
Technique called optogenetics used to pinpoint and take control of brain circuits involved in predatory behaviourIt has all the trappings of a classic horror plot: a group of normally timid individuals are transformed by scientists into instinctive killers, programmed to pursue and sink their jaws into almost anything that crosses their path.However, this hair-raising scenario was recently played out in a study of laboratory mice, designed to uncover the brain circuits behind the predatory instinct.

From Split to Psycho: why cinema fails dissociative identity disorder
M Night Shyamalan’s new movie, Split, stars James McAvoy as a character with 23 different personalities. And, like most screen portrayals of the disorder, it is seen as dangerous and violent. But what’s the truth behind the stigma?Tom Hanks played six different characters in Cloud Atlas, Eddie Murphy played seven in The Nutty Professor and Alec Guinness notched up eight in Kind Hearts and Coronets. But James McAvoy sets a new benchmark with his new movie, Split. He plays Kevin, a man with at least 23 distinct personalities – not all of them nice. This presents extra challenges for the young women Kevin has abducted and locked in his basement. Every time he walks into the cell, they have to work out who they are dealing with. Is it “Dennis”, the frowny, buttoned-up neat-freak? Is it “Patricia”, the prim, English-accented governess? Could it be “Hedwig”, the nine-year-old Kanye West fan? We don’t get to see all of Kevin’s alter egos, but enough to get the picture and to make this lurid little horror stand out from the crowd.Split’s writer and director, M Night Shyamalan, professes to having had a lifelong fascination with dissociative identity disorder (DID), formerly known as split personality, or multiple personality disorder, and frequently mislabelled as schizophrenia (which is an entirely different condition). He is clearly not the only one. DID is relatively rare in real life, but we have all heard of it, and we all think we know what it entails because cinema and television seem to be obsessed with it.
