Astronauts look forward to the arrival of cargo missions carrying fresh produce to liven up their diets as well as experiments and other suppliesTwo supply vessels blasted off within days of each other this week – both heading for the International Space Station (ISS).On 19 February at 14:39 GMT, Space X, a private company, launched a Falcon 9 rocket from pad 39a at NASA’s Kennedy Space Centre in Cape Canaveral, Florida. The launch pad is historic because it was built for the Apollo moon landing programme of the 60s and 70s. It was then used for space shuttle launches. Since April 2014, the launch pad has been used by Space X, which signed a 20-year lease with NASA. Continue reading...

I began studying economics at night school in Leeds in the 1950s and continued, at various institutions, as an external student of London University. Our courses were broadly, but not uncritically, Keynesian. We abjured fancy equations and sprinkled our essays with phrases like “a tendency to” and “pressure towards” this or that as a consequence of some other event. As a teacher I have tried to keep reasonably up to date, and learned in the early 70s, for example, to regard most monetarist nonsense as the fantasies of “Friedmaniacs”.With this background, and aware of the influence on our leaders of Oxford’s PPE (philosophy, politics and economics) course, I have often wondered what on earth they taught them. Andy Beckett’s article (The degree that runs Britain, 23 February) gives the answer. PPE graduates are “intellectually flexible”. Or, to put it another way, they sway with the wind. And the winds of monetarism and arrogant attempts to make human behaviours as subject to mathematical predictions as the laws of physics, have captured economics academia for the past 40 years. Conservative, Labour and, to our eternal shame, Liberal Democrats have been equally culpable, as the damage done to the bottom 20% in this country, and to 80% of the population of Greece, so clearly demonstrates.

Over time, the encyclopedia’s software robots can become locked in combat, undoing each other’s edits and changing links, say researchersFor many it is no more than the first port of call when a niggling question raises its head. Found on its pages are answers to mysteries from the fate of male anglerfish, the joys of dorodango, and the improbable death of Aeschylus.But beneath the surface of Wikipedia lies a murky world of enduring conflict. A new study from computer scientists has found that the online encyclopedia is a battleground where silent wars have raged for years.

Bees are better at problem solving than previously thought, and can learn tasks totally unlike their natural behaviour, say researchersBumblebees can learn how to manoeuvre a ball just by watching others carry out the task, researchers have discovered in the latest study to shed light on the insects’ surprising talents.While bees have already been shown to be able to learn how to pull on strings, push caps and even rotate a lever to access food, researchers say the new study shows that bees are better at problem solving than we thought.

Recent reports that it might be possible to use MRI to identify at-risk children are exciting, but we are still a long way from autism diagnosis by brain scanWhat if I told you that we can now identify babies who are going to develop autism based on a simple brain scan? This, in essence, is the seductive pitch for a study published last week in the journal Nature, and making headlines around the world.Early identification and diagnosis is one of the major goals of autism research. By definition, people with autism have difficulties with social interaction and communication. But these skills take many years to develop, even in typically developing (i.e., non-autistic) children. Potential early signs of autism are extremely difficult to pick out amidst the natural variation in behaviour and temperament that exists between all babies. Continue reading...

Study sheds light on approaches, revealing ‘orgasm gaps’ both between the sexes and those with different sexual orientationsThe female orgasm has often been described as elusive, but researchers say they might have discovered how to boost the chances of eliciting the yes, yes, yes.A study from a team of US researchers suggests that a combination of genital stimulation, deep kissing and oral sex is the “golden trio” for women when it comes to increasing their likelihood of reaching orgasm with a sexual partner.

Research by Dundee University and Derbyshire Fire and Rescue found that over 80% of the children tested did not respond to the sound of an industry-standard smoke detector operating. More than 500 volunteer families are being sought across the UK to join a study testing new fire alarm sounds which have a lower pitch and a woman’s voice

Scientists say even just 2.5 portions daily can lower chance of heart disease, stroke, cancer and premature deathFive portions of fruit and veg a day is good for you, but 10 is much better and could prevent up to 7.8 million premature deaths worldwide every year, say scientists.The findings of the study led by Imperial College London may dismay the two in three adults who struggle to manage three or four portions – perhaps some tomatoes in a sandwich at lunchtime, an apple and a few spoonfuls of peas at dinner.

Almost a fifth of land with the designation is neglected, but there are examples of rehabilitation with industrial sites being transformed into nature reservesGreen belts are coming under intense pressure from government plans to build thousands of homes. It conjures up an image of a tide of concrete being poured over beautiful rolling fields of wild flowers, but the original idea of the green belts was to prevent urban sprawl, not for nature conservation or even beautiful landscapes.Much of the green belt is not even green – 18% is classed as “neglected” with derelict buildings, rubbish, electricity pylons and other blots on the landscape. Only 45% is green and much of that is monoculture farmland too harsh for most wild plants to survive. Continue reading...

Nasa announced the discovery of seven Earth-like planets orbiting a star called Trappist-1, about 39 light years away, on Wednesday. The find has widely excited the astronomy community because of its implications in the hunt for alien life beyond the solar system. Three of the planets in the Trappist-1 system are in the habitable zone near the star and so could have water on their surfacesThrilling discovery of seven Earth-sized planets orbiting nearby star Continue reading...

There was an omission from your excellent obituary of Sir Peter Mansfield (21 February), the inventor of magnetic resonance imaging: the role played by the British Technology Group (BTG) in protecting his work. The commercial value of Peter Mansfield’s MRI invention was identified early on by an executive in BTG (previously the National Research Development Corporation), which at that time was entitled to all the intellectual property of university and government research in the UK funded by the public purse.BTG filed patents to protect the work and then found them being infringed by a major US company which was manufacturing MRI equipment. BTG spent several million pounds on litigation to defend the intellectual property. It was successful in doing so and subsequently licensed the company concerned that company and other international companies who were using the invention, achieving significant income as a result, which it shared with the inventor and his university.

My father, Ted Wilson, who has died aged 78, was a pioneering particle physicist at the European Organisation for Nuclear Research (Cern) in Geneva and a visiting professor at Oxford University.In 1967, Ted worked with Sir John Adams on one of the first giant particle accelerators, the Super Proton Synchrotron (SPS), which is 7km in circumference and stretches across the border between Switzerland and France. Revolutionary for its time – it was a predecessor of the Large Hadron Collider (LHC) – the SPS was switched on in 1976 and led to the discovery of the W and Z boson particles. It remains the second largest machine in Cern’s accelerator complex, after the LHC. Continue reading...

This week, Ian Sample explores the psychology behind ‘nudging’, its usage by governments, and some of the ethical quandaries involvedSubscribe & Review on iTunes, Soundcloud, Audioboom, Mixcloud & Acast, and join the discussion on Facebook and TwitterEvery day, each one of us is “nudged” by external factors and actors to change how we behave. Whether it’s the weather forecast, an advert on the train, or advice from a friend, we are all influenced by nudges. But what is a nudge? What is the human psychology behind their effectiveness? And when does a nudge become something more sinister – such as coercion or manipulation? Continue reading...

Research showed most people prefer not to glimpse the future, whether for the results of a football match or to find out if their marriage will lastWhether anticipating good news or bad, it turns out that most people would prefer to remain in the dark than sneak a glimpse of the future.According to research involving more than 2,000 participants, more than 85% would not want to know if their marriage would end in divorce, while a similar proportion wanted to remain ignorant of when they would die. Even for happy events, ignorance was often prized, be it in the case of Christmas gifts, or the upshot of a football match. Continue reading...

Don’t book your tickets for Pleistocene Park just yet: de-extincting mammoths is a nice thought experiment that’s overstayed its welcomeDe-extincting mammoths is back in the news this week. It’s been a few years so it was time for a return to science-fiction-land, much to the undoubted chagrin of science communicators, palaeontologists and museum professionals who are probably already fielding questions about mammoths’ proposed return to the land of the living.We’re told that scientists are “on the brink” of resurrecting mammoths through some whizz bang science and some nice juicy quotes about the breakthrough being “in a couple of years”. The rest of the story and headlines write themselves. Continue reading...

Funding response follows UN warnings that 40% of South Sudan’s population are in urgent need, with people already dying from hungerNew and existing funds provided by the EU and the UK government will be made available to South Sudan following the declaration of famine in the country.The UN has warned that about 40% of South Sudan’s population are in urgent need of humanitarian assistance and that people are already dying from hunger caused by famine in parts of the country.

To counter Trump’s administration, scientists need counter-propaganda, evidence-based alternative policies and political representationIt would surprise very few if surveys revealed that the vast majority of scientists and academics find the US presidency of Donald Trump abhorrent. After all, the scientific community shares values that are clearly not held by the Trump administration and its supporters: among them, the importance of diversity and the crucial role of evidence in the process of making smart decisions.What has been surprising is that the scientific community has not fully upheld these values in their initial responses in opposition to the Trump administration’s words and deeds over its first month in office. We need to up our game. We need more diverse ideas, more critical debate and more effective actions backed by evidence of what works. Continue reading...

Has the great urbanisation of our species over the last 5,000 years been good for humanity or bad? It’s a story that can be told by examining ancient skeletons – which reveal incredible dangers, but also point to a bright futureThe UN human settlements programme predicts that homo sapiens will soon be a majority urban species: 60% of humans will live in cities by 2030. More than 10 millennia of adaptations have gone into changing our lives from free-range to metropolitan. Yet in evolutionary terms this is a blindingly swift change of habitat, and to understand what it means for our future we must turn to the long view of archaeology.The accumulation of humans in dense habitations – cities – has had enormous and frequently fatal consequences. Problems of access to resources, disease transmission and pollution follow rapidly on the heels of our great urban experiment. And it is precisely these problems, originating many thousand of years ago, that we must come to terms with if we are going to survive as a species.

DNA sequencing shows insects crossed oceans then migrated from treetops to the ground to adapt to ancient climate changeA new paper shows that the ancient ancestors of termites found in northern Australia crossed vast distances over oceans, and then followed an evolutionary path similar to humans, migrating from tree-tops to the ground.Mounds sometimes reaching as high as eight metres and housing millions of individual insects are seen in the Northern Territory, Western Australia and far north Queensland, built by cathedral termites. Relative to the animals’ 3mm height and the average human height the termite mounds are the equivalent to four of the world’s tallest structure, the Burj Khalifa skyscraper in Dubai, stacked on top of each other.

Archaeologists say pair unearthed in London plague burial ground may have been related by blood or marriageThe skeletons of two men who were buried apparently hand in hand during an outbreak of the Black Death have been excavated from a plague burial ground in London.The men, believed to have been in their 40s, were buried in the early 15th century in a carefully dug double grave, in identical positions, with heads turned towards the right and the left hand of one man apparently clasping the right hand of the other.

Study shows significant increase in lifespan, with South Korea top of league table and other countries not far behindLife expectancy will soon exceed 90 years for the first time, scientists have predicted, overturning all the assumptions about human longevity that prevailed at the beginning of the 20th century.Women born in South Korea in 2030 are forecast to have a life expectancy of 90, a study has found. But other developed countries are not far behind, raising serious questions about the health and social care that will be needed by large numbers of the population living through their 80s.

Neuroscientist who carried out pioneering research on how damage to the central nervous system might be repairedIn 1969 Geoffrey Raisman, who has died aged 77, introduced the term “plasticity” to describe the ability of damaged nerve tissue to form new synaptic connections. He discovered that damaged nerves in the central nervous system (CNS) could be repaired and developed the theory that white matter (nerve fibres and supporting cells) is like a pathway – when it is disrupted by injury, such as spinal cord injury, growth of the regenerating fibres is blocked.In 1985 he described how olfactory ensheathing cells (OECs) “open doors” for newly formed nerve fibres in the nose to enter the CNS. Believing that reconstruction of the damaged pathway is essential to repair of the injured CNS and using the unique door-opening capability of OECs, in 1997, together with colleagues, Geoffrey showed that transplantation of OECs into the damaged spinal cord in experimental models repairs the damaged pathway and results in the regeneration of severed nerve fibres and the restoration of lost functions.

Are your pupils prone to feeling like a fraud when they succeed? Try these ideas to help them realise their potentialEver felt like a fraud at work? As if at any moment, everyone else is going to realise that you’ve bluffed your way to your current position? This phenomenon is known as the impostor syndrome, and even those who are at the top of their professional game feel it. Emma Watson recently admitted that she’s uncomfortable receiving praise because she feels like an impostor, and Rénee Zellweger and Kate Winslet have also acknowledged similar feelings.

Research finds distinctive language deficits in people with mild cognitive impairment, a precursor to dementiaRambling and long-winded anecdotes could be an early sign of Alzheimer’s disease, according to research that suggests subtle changes in speech style occur years before the more serious mental decline takes hold.The scientists behind the work said it may be possible to detect these changes and predict if someone is at risk more than a decade before meeting the threshold for an Alzheimer’s diagnosis.

To its critics, it is dangerous pseudoscience. To its supporters, it offers unique insights. What is the future of this controversial psychological test?Victor Norris had reached the final round in his application for a job working with young children, but he still had to undergo a psychological evaluation. Over two long November afternoons, he spent eight hours at the office of Caroline Hill, an assessment psychologist working in Chicago.Norris had seemed an ideal candidate in interviews – charming and friendly, with a suitable résumé and unimpeachable references. Hill liked him. His scores were normal to high on the cognitive tests she gave him, as were his results on the personality test he took. When Hill showed him a series of pictures without captions and asked him to tell her a story about what was happening in each one – another standard assessment – Norris gave answers that were a bit obvious, but harmless enough.

App development likened to the ‘wild west’ as researchers raise concerns over one-size-fits-all targets and absence of sound scienceFitness trackers and mental health apps could be doing more harm than good because they are not based on sound science, researchers have warned, comparing some health app developers to “snake oil salesmen of the 1860s”.Greg Hager, professor of computer science at Johns Hopkins University, said that in the absence of trials or scientific grounding it was impossible to say whether apps were having the intended effect.

With unprecedented access to news and knowledge, how do we make judgements about what we read? Neuroscience news is a case in pointIn an era of fake news and alternative facts, it seems as if our collective ability to critically assess information is starting to falter. We have unprecedented access to news and knowledge on a daily basis, but how do we make judgments about whether to accept what we read? There’s still a lot of work to do in this area, but an influential psychology experiment from 2009 might provide a good starting point – at least when it comes to thinking about how neuroscience is presented in the news.

Suicide attempts among high school students fell by an average of 7% following implementation of same-sex marriage laws, say researchersLegalisation of same-sex marriage in US states has been linked to a drop in suicide attempts among teenagers.Researchers say suicide attempts among high school students fell by an average of 7% following the implementation of the legislation. The impact was especially significant among gay, lesbian and bisexual teenagers, for whom the passing of same-sex marriage laws was linked to a 14% drop in suicide attempts. Continue reading...

Jealous rivals’ rumours about the supposed effeminacy of popular figures such as Humphry Davy left an enduring legacy, says Dr Heather EllisJealous rivals’ attempts to destroy 19th-century chemist Sir Humphry Davy’s popularity by insinuating he was gay have left a legacy that means the so-called hard sciences remain a bastion of sexism, a new book claims.Evidence unearthed by Dr Heather Ellis for her book Masculinity and Science, published by Palgrave, from the archives of the British Science Association, shows that Davy’s popularity created enemies who tried to destroy his reputation. Popular magazines, like the John Bull, launched vicious personal attacks on the chemist’s flamboyant dress and the charismatic delivery at lectures that had brought him a wide female following.

Physicist awarded the Nobel prize for his work as the inventor and main architect of the revolutionary MRI scannerMagnetic resonance imaging (MRI) is familiar to us all, and with some 36,000 scanners and 100m scans undertaken annually, it is hard to imagine a world without it. Yet it is only 40 years since the development of the MRI scanner, which revealed internal human anatomy in exquisite detail and revolutionised diagnostic medicine. Sir Peter Mansfield, who has died aged 83, was its inventor and principal architect.MRI uses the magnetic properties of hydrogen nuclei and in particular, those found in the water molecules that constitute more than half of our bodyweight. In a magnetic field they have two possible states, parallel and opposed to the magnetic field. A radiofrequency field precisely tuned to the energy difference between them will induce a transition (resonance). Mansfield realised that, in a magnetic field gradient, the resonance frequency would correspond to position, enabling an image to be generated. Continue reading...

For women, phone calls can keep long-distance friendships going, but men need to meet face-to-face, study showsMuch like a long-distance romance, it can be difficult to keep the spark alive in a friendship with someone living in a different city. Now scientists say they have uncovered the key to staying close – and it appears to be different for men and women.Men need to meet up face-to-face and bond over activities, according to the study of students leaving home for the first time, while for female friendships, long phone conversations can bridge the physical distance.

A new exhibition charts the changing place of electricity in our lives, our homes and in literatureImagine an invisible power. A force that can affect the world at a great distance, cause damage and healing, bring objects to you, show you images of faraway lands, cast light in dark places, even – sometimes – bring the dead back to life. There used to be a name for a force like that; the name was magic. But of course, that flexible, useful, intangible power has now been our servant for decades, in the form of electricity.In my novel, The Power, I imagine the changes that come to pass when all of a sudden almost all the women in the world develop the power to electrify – and electrocute – people at will. I liked the idea as soon as I thought of it; it seemed supple enough to bear some metaphorical weight, and less comic than giving women enormous muscles or the ability to emit poisonous gas from their nostrils. But the more I’ve learned about the history of electricity – fact and fiction – the more I’ve understood why the image of the electrified woman was such a perfect fit. It’s about women and magic, about women’s liberation via the promise of the “electrified home”, and about the way that electric power makes the weak strong. Although I hadn’t put this all together when I started work on the novel, I’m not the first person to imagine women’s empowerment as literally electric. Continue reading...

Ambitious Mosaic expedition will study weather patterns and life in melt ponds from vessel drifting with the ice currentIn 1893 the Norwegian explorer Fridtjof Nansen embarked on a mission of extraordinary boldness and ingenuity. He planned to become the first person to reach the north pole by allowing his wooden vessel, the Fram, to be engulfed by sea ice and pulled across the polar cap on an ice current.Ultimately, Nansen ended up abandoning the Fram and skiing hundreds of miles to a British base after he realised he was not on course to hit the pole, but the ship made it across the ice cap intact and the expedition resulted in groundbreaking scientific discoveries about the Arctic and weather patterns.

Scientists rally in Boston amid alarm over president’s views and fears for the future of the EPA, as ecologist likens current struggle to Galileo’sHundreds of scientists rallied in Boston on Sunday to protest what they call the “direct attack” of Donald Trump and Republicans on research, scientific institutions and facts themselves, as a community reckons, and argues, with a new era of American politics.Gathering in Boston’s Copley Square, outside the annual meeting of the American Association for the Advancement of Science (AAAS), several scientists gave speeches to a crowd holding signs shaped like beakers and reading “Stand up for science”. The speeches reflected a sea change in the culture of many labs and universities, where many researchers long maintained that good scientific work could speak for itself. Continue reading...

The president’s hyped-up behaviour at his Florida rally was an alarming display of his neediness. Maybe he should have his own theme parkTherapy has never been so expensive. At the weekend, it cost American taxpayers millions of dollars to fly Donald Trump down to Florida so he could hold a session with thousands of adoring fans after another trying week in the White House. At a cost of roughly $3m per trip, it would have been cheaper to hire Dr Freud but, sadly, aides who tried to contact him discovered he has been dead since 1939.Instead, the 45th president of the US invited on stage a man who later revealed he has a 6ft cardboard model of his hero and talks to it every day.

You wait longer when other people are behind you, we should stand on both sides of an escalator, and we usually get away with pushing in. Psychology professor Adrian Furnham explains what studies show us about standing in lineEvery Saturday at 7am, Adrian Furnham, professor of psychology at University College London, can be found shopping at his local supermarket. “It’s the same sad old gits, who recognise me,” he says. “But we know it’s very efficient. Although there are only two people on the till, I’m through the whole thing and back home within 20 minutes. I’ve tried shopping at different places and different times, and that is optimal.”Furnham studies queueing, but is not immune to its stresses. Last week, his latest research was widely reported as revealing a “rule of six” behind queueing behaviour: people will wait for only six minutes in a queue, and are unlikely to join one with more than six people in it. This simplification has a grain of truth. Six minutes of queueing does make people impatient, but it is not a magic length of time beyond which people stop waiting. For one thing, it depends what they are waiting for. “You won’t wait for six minutes at an ATM machine,” Furnham says, “but you will if you want concert tickets. Six minutes was the sort of average.” Continue reading...

This roving study of our enduring fascination with time travel covers well trodden ground but finds the concept constantly evolvingAre we trapped in the present, free to move in space yet unable to travel in the fourth dimension? Or is there a chance, a glimmer of a possibility, that the past and future could unfurl to our physical experience at will? Despite the punchline being apparent from the off – lest we forget, such journeys are impossible – James Gleick’s latest offering sets out to question the questions, probing how the idea of time travel emerged, gripped our imaginations and shaped our society.Our relationship with the slippery concept of time is far from static: technology continues to shape our view, even now Continue reading...
