Two hundred years ago a volcanic eruption cooled the Earth. Could it help us tackle global warming today?The island of Sumbawa in what is now Indonesia began to crack apart 200 years ago this week. On 10 April 1815, an explosion that could be heard a thousand miles away announced the largest volcanic eruption in recorded history. Mount Tambora, once among the highest peaks in the East Indies, was blown in half. Thousands in the immediate vicinity were killed by lava, wind, ash, fire and tsunamis, but the volcano’s effects echoed far further and longer. The force of the explosion catapulted millions of tonnes of sulphur miles upwards into the stratosphere where it was held aloft. A haze encircled the planet, providing it with a temporary sunshade. Over the next three years, Tambora cooled the surface of the planet by a degree celsius.In Europe and America, crops failed, diseases flourished and riots and famine broke out. The year 1816 became known as the “year without a summer”. Farmers, philosophers, artists and writers struggled to make sense of their new weather. In a recent book Gillen D’Arcy Wood describes the indelible mark the volcano has left on our culture. In England, Constable and Turner used unusual quantities of red paint as they reproduced the vivid volcanic sunsets. In June 1816, as snow fell in New York, four friends on the shores of Lake Geneva were kept inside by relentless rain and storms. The ghost stories that they told one another led to Tambora’s most famous cultural offshoot, Frankenstein. Mary Shelley described in her introduction the “wet, ungenial summer” that inspired her parable of irresponsible science, which she subtitled “The Modern Prometheus”. Continue reading...

The processes in their brains during hibernation are exciting scientistsThis month, Arctic ground squirrels emerge in Alaska after eight months’ hibernation. It hasn’t been easy: during hibernation, their body temperature can drop as low as -2.9C, a record for mammals, and stay there for two to three weeks before they undergo a bout of shivering to warm up. Scientists are scrutinising this mechanism to see how temperature management can help humans to recover from cardiac arrests and strokes.“We and others have identified at least one mechanism that the [squirrel] brain uses to control this onset of hibernation,” says Professor Kelly Drew, who studies hibernation biology at the University of Alaska Fairbanks. “That mechanism has potential to guide development of drugs that uses the same mechanism to cool people.” Continue reading...

Although it seems counterintuitive, tests indicate that plucked follicles ‘communicate’, causing an immune response that leads to regrowthBaldness is often dreaded by men and there are few, if any, satisfactory options for reversing it. Now scientists have discovered a potential solution, after showing that plucking hair out could actually stimulate growth.The counterintuitive discovery, in mice, demonstrates a previously unknown method for triggering hair regeneration. Although the work is at an early stage, the authors believe the same process could be helpful for tackling hair loss in men or people with alopecia. Continue reading...

Although an effective therapy is still some years off, trial using high doses of antibody reduced HIV levels in patients’ blood systems 300-foldResearchers are a step closer towards an antibody treatment for HIV, after trials of an experimental therapy reduced the amount of virus in patients’ blood.A small trial in 17 HIV patients found that high doses of an antibody could slash levels of virus in patients’ bodies, though scientists warned that an effective therapy was still years off.

Lynne Featherstone accepts advisory council’s recommendation of 12-month ban on substances including most widely used alternative to cocaineFive legal highs, including an alternative to cocaine that is one of the most common in Britain, are to be banned from midnight on Thursday, ministers have announced.The drug minister, Lynne Featherstone, said she had accepted a recommendation from the government’s official drug advisers that the five legal highs should face a temporary ban of 12 months while a full assessment of the harm they posed was undertaken.Related: The hidden dangers of legal highsEthylphenidate-based products are a growing issue and their use is associated with bizarre and violent behaviourRelated: Legal high drug deaths soar in UK Continue reading...

Fully autonomous weapons should be banned by international treaty, says a report by Human Rights Watch and Harvard Law SchoolFully autonomous weapons, already denounced as “killer robots”, should be banned by international treaty before they can be developed, a new report urges the United Nations .Under existing laws, computer programmers, manufacturers and military commanders would all escape liability for deaths caused by such machines, according to the study published on Thursday by Human Rights Watch and Harvard Law School.

Male relatives of sex offenders five times more likely to commit similar crimes, and 40% of risk is genetic, study suggestsBrothers of men convicted of sexual offences are five times more likely than average to commit the same types of crimes, scientists have found.The study suggests that genetic factors are largely responsible for the effect and that environmental factors, such as sons learning from fathers, have only a minor influence. The authors urged authorities to consider interventions for the male relatives of sexual offenders, including counselling on appropriate sexual behaviour or even offering medications designed to lower sex drive.

Despite its relegation to a subset of the Apatosaurus family in 1903, new research suggests that the Brontosaurus is distinct enough to be a genusThe Brontosaurus has been consigned to extinction not once, but twice – the second time when scientists concluded it was too similar to other long-necked dinosaurs to deserve its own genus.Now the “thunder lizard” looks set to make a comeback, after a new analysis suggests that Brontosaurus specimens are sufficiently distinct from other species after all.

Drawing on the widest survey of sexual behaviour since the Kinsey Report, David Spiegelhalter, in his book Sex By Numbers, answers key questions about our private lives. Here he reveals how Kinsey’s contested claim that 10% of us are gay is actually close to the markFor a single statistic to be the primary propaganda weapon for a radical political movement is unusual. Back in 1977, the US National Gay Task Force (NGTF) was invited into the White House to meet President Jimmy Carter’s representatives – a first for gay and lesbian groups. The NGTF’s most prominent campaigning slogan was “we are everywhere”, backed up by the memorable statistical claim that one in 10 of the US population was gay – this figure was deeply and passionately contested.Related: Gay Britain: what do the statistics say?The proportion of people with same-sex experience is higher than the proportion who identify as gay and bisexual Continue reading...

The underlying realities of the world – from Earth’s rotation around the sun to Darwin’s theory of evolution – are rarely obvious or expectedAll is not what it seems. Much of the universe – from the unimaginably small to the cosmological – is not how it appears to us, and our view is lamentably limited. The Earth’s rotation around the sun has been accepted for less time than it was not, and we still don’t yet know what makes up most of the cosmos. The knowledge that all life is built of cells is less than two centuries old, that all life is encoded in DNA has been known for just 50 years. When Darwin came up with evolution by natural selection, his loyal ally TH Huxley exclaimed “How extremely stupid, not to have thought of that!”But evolution is not obvious at all, and it took thought and experiment and hard tenacious graft to reveal that truth. The real structure of the universe – the atomic, subatomic and quantum – was concealed from our eyes for all but the tiniest fragment of our tenure on Earth. We humans are awful at perceiving objective reality. We come with inbuilt preconceptions and prejudices. We’re dreadful at logic, and see patterns in things that are not there, and skip over trends that are. We attribute cause and agency to chance and coincidence, and blame the innocent as the root of all manner of evil. We use the phrase “common sense” as an admirable quality for scrutinising the world in front of us.Our senses and psychology perceive the world in very particular ways that are comically easy to fool.Related: Why racism is not backed by science Continue reading...
