A Nasa animation demonstrates how a star would be ripped apart if it got too close to a black hole in space. When a star enters close proximity to a black hole, intense tidal forces rip the star apart. Stellar debris is flung outward at high speed while the rest of the star descends towards the black hole, causing a flare Continue reading...

A genetic study of giant tortoises on the Galapagos island of Santa Cruz reveals two different species and causes some head scratching amongst taxonomistsIn 1902, American naturalist Rollo Beck stepped ashore on the Galapagos island of Santa Cruz. He’d been urged by his patron Walter Rothschild “to leave no stone unturned” in his efforts to collect giant tortoises from the island and “after a long and wearisome hunt,” he came up trumps. One of the seven specimens Beck collected became the type specimen for the tortoises on this island, now referred to as Chelonoidis porteri.But just over a century later, in 2005, geneticists demonstrated that there appear to be two distinct species on the island. The two lineages live just 20 km apart yet the clear genetic differences indicate they have been heading in different evolutionary directions for at least 1.7 million years. Continue reading...

Father of the space shuttle who played a vital role in the Apollo 11 moon landingOn 21 May 1961, soon after the Soviet Union had launched Yuri Gagarin into space and in the aftermath of the abortive Bay of Pigs invasion of Cuba, the beleaguered US president, John F Kennedy, made a rash promise to Congress. He pledged that the US would land an American on the moon and get the astronaut safely back “before this decade is out”. The systems engineer George Mueller, who has died aged 97, was a key reason why Kennedy’s pledge was fulfilled on 20 July 1969, as Neil Armstrong and Buzz Aldrin stepped on to the moon.Mueller arrived at Nasa as associate administrator for manned space flight in September 1963, just weeks before Kennedy’s assassination. He immediately commissioned an assessment of the prospects of fulfilling Kennedy’s goal. The odds were one in 10, he was told. Between 1963 and 1966, Mueller, drawing on his experience of US air force methods, transformed Nasa. Continue reading...

After nine years of government attacks on Canadian research, the science community is looking forward to a fresh start under Justin Trudeau.There was a palpable outpouring of relief from Canadian scientists as the Liberal Party won a majority on Monday night, bringing to an end nine years of escalating hostility by the Harper government towards its own research base. Drastic cuts to funding and constraints on scientific freedom have significantly damaged Canadian research and its capacity to develop science-based public health and environmental policies.Harper’s assault on science was extensive: with government scientists censored, budgets chopped, data monitoring programs eliminated, scientific libraries shuttered and the contents thrown into dumpsters. The long form census was axed, depriving decision makers of vital information about their citizens. Continue reading...

The Wellcome Trust today unveils its new strategy, with a commitment to spend more and spend smarter in areas where it can make the biggest difference.A month out from the November spending review, Britain’s scientists are braced for bad news. Rumours continue to swirl about another five years of flat budgets, a likely merger of research councils, and the culling of other funding bodies. Next Monday, the pressure group Science is Vital is hosting a rally at Conway Hall in London where prominent voices from across the research community will spell out the case for public investment.So in these uncertain times, today’s announcement by the Wellcome Trust is a shot in the arm for UK science. The trust, which is now the second highest-spending foundation in the world, will significantly boost the amount it invests in research, to a total of £5 billion over the next five years. The ambition of this is clear when set against £6 billion that the trust has spent over the past decade, and £11 billion since it was first set up in 1936. Continue reading...

My father, Raymond Smith, who has died aged 90, was a major figure in postwar social anthropology. His work, and his life, were focused on kinship in the Caribbean and the US. His gift and his good fortune was to be a friend and supporter of the first generation of West Indian scholars to reach maturity as independence became a reality. Together they put social sciences on the map at the University of the West Indies in the 1960s.Undertaking field work in British Guiana (now Guyana), he met Flora Tong, a social worker and teacher seconded to work with him as a research assistant, and began his long engagement with the politics and sociology of the Caribbean. One of his earliest books, British Guiana (1962), combined an account of the country’s social history with an analysis of its racial politics, which are depressingly familiar 60 years later.

Prey species evolve a variety of ways to avoid predators, including camouflage, conspicuous colouration, and chemical toxins. But a new study of amphibians indicates that evolving toxins against predators increases the rate of extinction for prey speciesPrey species evolve a variety of ways to avoid their predators, including chemical toxins, camouflage, and conspicuous colouration. But what are the potential costs associated with anti-predator defences? According to a study of amphibians published today in the journal, Proceedings of the National Academy of Sciences, chemical defence and conspicuous colouration enhance speciation rates in prey species, as predicted. But unexpectedly, evolution of chemical defences also increases extinction rates -- even above the rate of speciation. As a result, developing chemical defences against predators increases the overall risk of extinction for prey species. Continue reading...

In the social media age, we know how to connect: but are we forgetting how to talk to each other? Leading US psychologist Sherry Turkle wants to fight backFor nearly 30 years now, Sherry Turkle, professor of social psychology at the Massachusetts Institute of Technology, has been exploring the effects of digital worlds on human behaviour. Her books, Life on the Screen, The Second Self and Alone Together, have charted the seductions of “intimate machines”, the advance of social media and virtual realities and the all-pervasive internet, and the effect these things have had on our culture and our lives. Her latest book, Reclaiming Conversation: The Power of Talk in the Digital Age, is a call to arms to arrest what she sees as the damaging consequences of never being far from email or text or Twitter or Facebook, in particular the impact it has on family life, on education, on romance and on the possibilities of solitude. Using extensive interviews and half a lifetime of research, she suggests – with reference to the birth of the environmental movement in the 1960s – that we are at a “Silent Spring” moment in our infatuation with life on screens rather than life in the real world, never wholly in one or the other. She measures these effects in a breakdown of empathy between children, in the consequences of increasingly distracted family interaction and a growing need for constant stimulus. Her antidote is a simple one: we need to talk more to each other. This interview took place by telephone last week.You have been writing about these issues for a long time now. Has it always felt like a losing battle?

Visionary scientist Alfred Wegener was ridiculed for his radical theory of continental drift. A century later, his icy grave proves his pointOne hundred years ago, a German explorer and scientist published a work that would revolutionise our understanding of our planet. In The Origin of Continents and Oceans, Alfred Wegener proposed the radical idea that Earth’s continents had, hundreds of millions of years before, formed a vast single land mass that had subsequently broken apart, with those broken pieces eventually drifting to their current locations. Our world’s mountains, forests and civilisations rest on a bedrock that is not immutable but shifts, albeit very slowly, Wegener argued.David Attenborough recalls asking a lecturer in the 40s about continental drift. 'It was moonshine, I was informed.' Continue reading...

Cookery programmes put us in a hallucinatory state where we think we can smell the food we seeSince the The Great British Bake Off finished, you may miss the delicious cake smell that seemed to waft out of the television every time Nadiya opened the oven. Thinking about it right now may have a similar effect - you can almost taste the butter icing, can’t you? This isn’t smell-o-vision but a kind of hallucination. The smell of cooking is particularly enticing and memorable because it reminds humans that we were clever enough to create fire. This meant we didn’t need to evolve a second stomach to liberate energy from ingredients, like cows. So memories in the brain’s sensory cortex are stimulated when we see, hear or imagine a cake being baked on TV in a similar way to when we’re in an actual kitchen. It may not feel quite the same, and, of course, the inability to distinguish between the physical world and our sense memories is a form of mental illness. But as far as parts of your brain are concerned, as you watched the contestants put the finishing touches to their entries, there might as well have been a real cake in front of you. Just with far fewer calories and no washing-up. Maybe that’s why the show is so popular…Dr Daniel Glaser is director of Science Gallery at King’s College London Continue reading...

We may put beautiful people on billboards, but it’s the average looking we’re drawn to, says Richard Stephens

Does it matter if you are left or right handed? Take this simple test to see what your level of ‘handedness’ reveals about youWe’re often told that left-handed people are more creative. When it comes to evidence, the jury’s still out, but the hand you prefer is less important than how much you prefer it: that is, whether you’re one-handed or ambidextrous. For each of these activities, which hand do you use – always left, usually left, both equally, usually right or always right?

There is still not enough money going into research and developmentAs a nation, our productivity has stalled. This stagnation directly affects the nation’s financial health and our citizens’ quality of life. As the government ponders where to wield the axe on departmental budgets in the run-up to the comprehensive spending review (CSR), the importance of government funding for research and development (R&D) needs to be kept in sharp focus.Last week, I had the pleasure of receiving an honorary degree from the University of Manchester, a university that sits at the very centre of the so-called northern powerhouse. As I waited to be honoured, I reflected on the patchiness of current government policy towards R&D investment. Continue reading...

Opponents of Transatlantic Trade and Investment Partnership say EU negotiator has admitted to approving entry of banned goodsEU negotiators will resume controversial trade talks with the US on Monday amid claims that multinational companies have jumped the gun in advance of any agreement to import goods that are currently banned – including genetically modified crops and chemically washed beef – into European markets.

In Denmark, letting a child see zoo animals being cut up is normal - what can it teach a young child?My three-year-old daughter is transfixed by a bandage tied around the lion’s rear shin, there to hide the spot where the zoo has cut away a strip of fur from the ligaments in advance.“It’s got a big plaster,” she says over and over again. “Little lion, little lion. It’s got a big plaster.” She likes plasters, Eira. They’ve been an obsession ever since she gashed her forehead a year ago and sported one for several weeks. Continue reading...

Ancient teeth found in China suggest Homo sapiens was outwitted by its rivalsThe discovery of a hoard of ancient human teeth in a Chinese cave has forced scientists to reconsider our species’ relations with our closest evolutionary cousins, the Neanderthals. The find, revealed in the science journal Nature, shows modern humans must have left their African homeland and reached southern China more than 80,000 years ago.This unexpectedly early date contrasts with our ancestors’ far more recent arrival in Europe - about 45,000 years ago – and suggests Homo sapiens was prevented, for some reason, from moving there for tens of thousands of years. Anthropologist María Martinón-Torres, from University College London – a member of the team that made the discovery – is confident of the reason. She blames the Neanderthals. Continue reading...
