New model suggests that as the universe expands everything from galaxies to space-time itself will be torn apart - but not for about 22 billion yearsEverything we know, and everything else besides, burst into existence at the Big Bang. Now scientists have concluded that we could be heading for an equally dramatic cosmic finale: the Big Rip.A new theoretical model suggests that as the unive
Trial showed healthy people given a Parkinson’s drug became more selfish, while people given a serotonin-boosting drug were more protective of others Common drugs for depression and Parkinson’s can sway people’s moral judgments about harming others, according to research that raises ethical questions about the use of the drugs. The study found that when healthy people were given a one-off
Vaccine may have caused narcolepsy by triggering the production of antibodies which destroy a sleep-regulating part of the brain, a new study suggestsScientists appear close to pinpointing why a swine flu vaccine given to six million people in Britain triggered the devastating sleep disorder, narcolepsy, in rare cases.The Pandemrix vaccine, made by GlaxoSmithKline (GSK), and which was reco
The founder of Africa’s first drug discovery and development centre explains why scientific research is key to unlocking the continent’s potentialThe continent of Africa suffers a crippling disease burden, which continues to choke economic growth in addition to causing high morbidity and mortality. It is therefore vital for Africans to contribute to finding solutions to their health problems.
Discovery rules out many theories of comet formation by demonstrating that comets have substantial variations in their internal structuresCameras on the Rosetta spacecraft have spotted a series of enormous pits on comet 67P/Churyumov-Gerasimenko that plunge hundreds of metres down into the body’s cold interior.Scientists on the mission believe the pits formed in the same way as sinkholes o
The survey of 350,000 people across four continents did not, however, confirm a belief of a link between genetic variety and high cholesterol or blood pressureThe children of parents who are more distantly related tend to be taller and smarter than their peers, according to one of the largest studies to date into genetic diversity.The study suggests that height and intelligence may be incr
Studies on mice show two existing medicines could help restore protein production in brain and prevent memory loss, speeding up search for cureTwo licensed drugs have been shown to halt brain degeneration in mice, raising the prospect of a rapid acceleration in the search for a medicine to beat Alzheimer’s disease.The results, presented on Tuesday at the Alzheimer’s Society annual research
Hermaphrodite flatworm is able to self-fertilise thanks to an evolutionary development resulting in a needle-like penis, scientists have discoveredThe pursuit of reproductive success in the animal kingdom sometimes calls for extreme measures. But few creatures can match the hermaphrodite flatworm, which scientists have discovered can reproduce by injecting sperm into its own head.The tiny
Campaigners including Brian May and Lord Rees are marking Asteroid Day by raising awareness of the the threat posed to the planet by speeding space rocksThe search for deadly asteroids that could slam into Earth must be speeded up 100-fold to help protect the future of life on Earth, according to an influential group of scientists, astronauts and rock stars.

With LGBT civil rights in the news, Georgina Voss argues that science institutions need to extend their equality initiatives to queer scientistsWhen Sir Tim Hunt’s comments about women in science broke, one element in particular jumped out at me. Hunt was, he said, in favour of gender-segregated laboratories as a way of sidestepping the mess arising from scientists in love. The notion that sa

The UK is currently experiencing something of a heatwave. However, as much as people claim to look forward to and enjoy hot weather, the evidence suggests that people are actually far more aggressive and violent when the temperature rises. What is it about the heat that makes people so angry?Wednesday 1 July saw the hottest July day in the UK on record, and of course the population and the me
Spiders can use their legs or abdomens as “sails”, helping them to disperse across large bodies of waterIf, last week, you’d quizzed me about the dispersal strategies of spiders, I would have told you all about “ballooning”, how Charles Darwin, at sea on the Beagle in 1832, was stunned to see thousands of tiny, dusky red spiders come floating on board, borne on silky parachutes that trapped t
Asteroids could potentially cause substantial damage to the planet. Better observational data and analysis could help us to avert disastrous strikesThe aim of Asteroid Day is to inform the public and raise awareness about the possibility that asteroids can collide with the Earth in the future. Today was chosen to highlight the risk because on the same day in 1908, a 30m object entered the atm
Astrophysicist Dr Brian May has spoken to the Guardian about Asteroid Day, and saving the planet from the threat of incoming space rocksBefore Queen, Brian May was an astrophysicist. He has held a life-long fascination with space and is now devoting more time promoting the study of the cosmos to others. He is a key figure behind Asteroid Day, a series of almost 100 events around the world.
Queen guitarist and astrophysicist Brian May warns of the threat to Earth from a meteor strike. He's among a group of experts calling for more effort to find and track potentially dangerous asteroids. 'We are under threat from a meteor strike. This is a catastrophe that could be averted,' he says to mark the first ever 'asteroid day' Continue reading...
