Children and their mobiles: psychologists' views on a modern obsession
Psychologists discuss how parents and teachers can limit the impact of smartphones on young people’s wellbeing and learningTeaching talk turned to smartphones this week, with the announcement of a new government study into the impact of mobile devices on behaviour and the news that a fifth of secondary school pupils are using social media in the middle of the night, with predictable consequences for sleep quality and concentration at school.The majority of teachers did not grow up in the digital era. That’s not to say that behaviour and bedtimes were trouble-free before smartphones – hands up if you ever got told off for reading under the duvet with a torch – but it does mean they’re facing an unfamiliar issue. We spoke to educational psychologists to get their ideas and advice on the way to approach this 21st-century problem. Continue reading...
'Sonogenetics' allows brain cells to be controlled by sound waves
Scientists have used genetically modified worms to show that ultrasound can be used to activate brain, heart and muscle cells from outside the bodyScientists have bred worms with genetically modified nervous systems that can be controlled by bursts of sound waves.The tiny nematodes change direction the moment they are blasted with sonic pulses that are too high-pitched for humans to hear.
Clarity must begin at home if England are to win Rugby World Cup | Robert Kitson
Experts say hosting the World Cup ‘could be an extraordinary advantage’ for England – but only ‘if they’ve managed the psychology in the right way’It’s World Cup anthem time. There is a red rose on your chest and you are standing on the pitch at Twickenham. Up in the stands all you can see are tense English faces. Failure is unthinkable. As the New Zealand coach, Steve Hansen, correctly observed the other day: “The big thing England have to cope with is the massive expectation on them at home … the English will expect them to win.”If anyone understands the pros and cons of home advantage it is the All Blacks. Four years ago they lifted the Webb Ellis Cup despite knowing an entire nation would never forgive them if they fell short. Brazil’s footballers, in a similar situation last year, coped rather less well. Playing at home only takes you so far, as England will shortly discover. “This World Cup has several potential winners which means the quality of their mental preparation could make all the difference,” says Jeremy Snape, the former England cricketer turned performance coach.

Fungus: the stuff of life
Claxton, Norfolk They process the hard lignin and resistant woody tissues, converting it into elements that trees and flowers can re-useIt seems apt that mushrooms are made from the same stuff as insects – chitin – because, like insects, they have a gift for sudden appearance. One moment nothing, then, as if on wings, they descend everywhere. We must acknowledge that this fungal sense of the dramatic relies partly on us. We simply fail to notice something so lowly, so brown, so inhuman, and yet so fundamental to life, until it does something eye-catching.In our garden the best display has been mounted on the back lawn. Despite a fey hint of Gallic artistry or culinary sophistication in the name – and they are said to be delicious – some of these fairy ring champignon look like small crumpled turds.

No silver jubilee for Queen Victoria | Letters
Queen Victoria did not enjoy a silver jubilee (Who is the UK’s queen of queens?, 5 September). Apart from her not being in a condition to enjoy anything in 1862, a few months after Prince Albert’s death, the concept was unknown. “Jubilee” still meant a 50-year event, as in Leviticus, or an occasional year decreed by the pope for particular purposes. The first royal “silver jubilee” was that of Kaiser Wilhelm I in 1886; the next noted by the Times was that of the King of Siam in 1893; the first British royal “silver jubilee” was that of George V in 1935.

Birds in love produce more babies, study shows | @GrrlScientist
A new study finds that birds who freely choose their own mates have 37 percent more offspring than those which were paired up by researchers in a sort of avian ‘arranged marriage’ — findings that have far-reaching implications for conservation and captive breeding practicesBirds who freely choose their own mates produce 37 percent more offspring than those which were paired up by researchers in an avian “arranged marriage”, according to research published today in the peer-reviewed journal, PLoS Biology. Additionally, cross-fostering experiments revealed that embryo mortality depended upon the compatibility of the genetic parents, whereas chick mortality depended upon the the behavioural compatibility of the foster parents. Further, although parents that freely chose their own mates had similar rates of embryo mortality to that of birds in “arranged marriages”, those birds that had freely chose their own mates were much better at raising their chicks. This suggests that birds may be choosing mates based on behavioural compatibility -- a finding that has important implications for conservation of animals that form pair-bonds. Continue reading...

I'm striking for the first time because government scientists are so poorly paid
Researchers who plan for natural disasters and climate change are stuck with the public sector pay freeze, while our colleagues in universities enjoy risesThis week, on 14 September, I walked out of my job for a half-day of strike action, alongside my colleagues at the Natural Environment Research Council (NERC).I’ve worked within the council and its precursors for 23 years and this is the first time we’ve ever balloted members about taking action on pay. It’s not something that’s generally a big motivator. NERC members – scientists and researchers – enjoy their work and are proud to contribute to the likes of the British Antarctic Survey, the Geological Survey, the National Oceanography Centre, the Sea Mammal Research Unit.

SchoolDash: the school performance data tool for teachers, parents - and even estate agents
A new website from the founder of Digital Science aims to make it easier for a range of school stakeholders to sift through the huge amount of data about education performance across EnglandThe problem with big data is that it’s not always that easy to wade your way through it. The UK Department for Education, for example, provides a mammoth amount of information about schools – average class sizes, absence levels, details on how many pupils are eligible for free school meals (and how many are actually having them), and a wealth of measures that aim to assess how well children are performing across the school years. But trying to make sense of a sea of numbers in spreadsheets and tables doesn’t always help you to get a sense of what’s actually going on in schools around the country.This is where Timo Hannay comes in. “About 18 months ago some local schools where I live in East Finchley asked for help in data analysis. Being the slightly obsessive geek I am, I ended up downloading reams of data from the DfE website and building a huge database covering every school in the country”, he says. Hannay has an eye for data. He has a PhD in neuroplasticity, and for a number of years was the director of web publishing for Nature Publishing Group. He then went on to found Digital Science, a startup company focusing on software and services aimed at scientists and research administrators. Now, he can add educational cartographer to the list.

I have cancer in my 20s. How am I supposed to cope? | Kathleen Brady
I’ve been forced to pause my life before it’s barely begun. Facing the unknown is petrifying – but facing my friends is almost as hardWhile it’s fair to say that a cancer diagnosis at any age seems unfair, to be diagnosed in your 20s goes against everything we expect. You’re supposed to be getting started in life, finally finding a job you enjoy, learning how to scrape together some savings, maybe finally moving in with a partner. Perhaps you’re buying a home, trying new things and meeting likeminded people. You’re meant to be healthy: healthy enough to hold down a good job, go out every weekend, travel at a whim and generally enjoy your life.The most frustrating and isolating thing is that no one knows how to react. I’m the first Continue reading...

Five years: five reasons to be angry about science funding
Failure to commit to a reasonable level of public investment in research is bad for science – and bad for Britain. Here’s what you can do about itIn September 2010 the Government threatened cuts to the UK’s research budget, igniting the Science is Vital campaign and rallying thousands to protest against policies that would harm the floundering economy. Five years later – incredibly – we appear to be facing exactly the same predicament. So Science is Vital is campaigning once again, calling on scientists and supporters of science to join us at a public event (in London and online) next month.Back in 2010 our efforts, along with that of many others, resulted in a ring-fence for the publicly funded science budget – a freeze rather than a cut.

This face tells us why we must rethink our views on our ancestors
The discovery of at least 15 individuals’ bones in a South African cave has been hailed as a major findMore than 1,500 fossils from the Rising Star cave system in South Africa have been named as a new human species, Homo naledi, one which displays a unique combination of human and non-human traits throughout the skeleton.In September 2013, two cavers discovered bones in an almost inaccessible chamber deep within the Rising Star cave system, about 25 miles from Johannesburg in South Africa. Two months later a team led remotely by palaeoanthropologist Lee Berger of the University of Witwatersrand (remotely because only excavators much slenderer than Berger could squeeze themselves into the chamber) was recovering a haul of fossil human bones. The extraction of the remains was widely publicised, along with numerous videos and live feeds, and I’m sure I wasn’t the only one who thought that the coverage had more hype than substance.

The nudge theory and beyond: how people can play with your mind
Mental manipulation can be backed by good intentions – but when used with stealth, it is deceitful and wrongA couple of decades ago, a class of psychology undergraduates played a mean trick on their lecturer. The students on the right side of the room gently nodded, smiled, and looked thoughtful, while those on the left seemed bored and glum. Before long, the unsuspecting lecturer was addressing the “right” students with enthusiasm, with only the odd uncomfortable glance to the rest. On some secret sign, the students changed roles – and the lecturer duly switched to addressing students to the left. Memories are vague on how often the hapless lecturer was pushed to and fro.The students’ hilarity was no doubt considerable, especially as the trick used one of the key principles they were being taught: that pigeons, rats or lecturers do more of what is rewarded, and less of what is punished. But how did the lecturer feel when the trick was revealed? In his shoes, I imagine myself trying to summon a brave laugh, but feeling pretty dreadful. Even where no malice is intended, the sense of having been manipulated is hurtful indeed. Continue reading...
Blue moods may be connected to our perception of the colour
Dopamine, which stimulates the pleasure centre in the brain, is also involved in transmitting visual information“Feeling blue” might be more than just a metaphor. Indeed, how we feel about the world can play a huge role in how we see it, according to a study in the journal Psychological Science. Feeling sad can keep us from seeing in certain colours, as though we live in Dorothy’s Kansas. But a good mood can bring those colours back into the world, just like a tornado trip to Oz.Related: How we all could benefit from synaesthesia Continue reading...

Blind cave fish evolved a shrunken brain to save energy
The Mexican tetra lost its eyes - as well as a significant portion of its brain - to ensure survival in a subterranean environmentAt some point back in deep time, a group of fish were washed into a limestone cave somewhere in northeastern Mexico. With no way out and little more than bat droppings to eat, the fish began to adapt to their new troglodytic lifestyle. Unable to see other members of their group in the dark, they lost their colourful pigmentation. Then they lost their eyesight, their eyes gradually got smaller, and then disappeared altogether.This was accompanied by a dramatic reduction in the size of the brain’s visual system. Yet, the question of why the blind cave fish lost its eyes and a large part of its brain remains unresolved. Now, biologists in Sweden believe they have found the answer. In new research published today, they report that loss of the visual system saves the fish a substantial amount of energy, and was probably key to their stranded ancestors’ survival.

The good news from Homo naledi: we humans are not alone | Julian Baggini
If ancient hominids really buried their own dead, it could transform attitudes to our evolutionary presentOne of the curious features of science news is that the excitement it generates bears little or no relation to our ability to understand it. Kudos to you if you can explain to me what a Large Hadron Collider actually is, but anything more precise than “a huge ring under a mountain for smashing particles into each other”, and you’re a member of the cognoscenti. Yes, I know it resulted in the discovery of the Higgs boson, but just because I can say it doesn’t mean I understand it.A similar kind of uncomprehending buzz has greeted the discovery of the bones of at least 15 individuals in a South African cave system. These may be members of a hitherto unknown species, Homo naledi – perhaps our earliest ancestor, living as long as 4 million years ago. Continue reading...
Lake District forests hit by ash dieback disease
Sites affected by Hymenoscyphus fraxineus fungus include areas of woodland near Ambleside and Keswick, with disease already widespread across EuropeTrees at four different sites in the Lake District have been found infected with ash dieback disease, according to the Forestry Commission. The sites include areas of woodland near Ambleside and Keswick.It is not known how the trees became infected with the Hymenoscyphus fraxineus fungus (which was originally called Chalara fraxinea). Charlton Clark, a spokesman for the Forestry Commission, said: “The disease can be spread either by spores of the fungus being carried by the wind or by movement of infected ash plants, whose spores can then be blown to neighbouring trees. It could have arrived in the Lake District by either or both these means.” Continue reading...
Burning all fossil fuels will melt entire Antarctic ice-sheet, study shows
Oceans would rise by over 50m sinking land inhabited by a billion people and changing the face of planet Earth, say scientistsBurning all the world’s coal, oil and gas would melt the entire Antarctic ice-sheet and cause the oceans to rise by over 50m, a transformation unprecedented in human history. The conclusion of a new scientific study shows that, over the course of centuries, land currently inhabited by a billion people would be lost below water.“For the first time we have shown there is sufficient fossil fuel to melt all of Antarctica,” said Ricarda Winkelmann, at the Postdam Institute for Climate Impact Research in Germany, who led the research published in the journal Science Advances. “This would not happen overnight, but the mind-boggling point is that our actions today are changing the face of planet Earth as we know it, and will continue to do so for tens of thousands of years to come. If we want to avoid Antarctica to become ice-free, we need to keep coal, gas and oil in the ground.” Continue reading...
Why I'm sceptical about the idea of genetically inherited trauma
A recent scientific paper claiming that the children of Holocaust survivors showed evidence of inherited stress was deeply flawed - here’s whyRecently, the Guardian published a story based on a scientific paper that claimed the stress experienced by Holocaust survivors somehow was detectable in their children through a process known as epigenetics. The paper was riddled with flaws: the scientists studied blood, which is a mixture of cell types, meaning there are any number of causes for the changes reported. The scientists only looked at a tiny subset of genes. They had an absurdly small sample size of 32 people, a tiny eight-person control group, who didn’t really look like good controls, and produced a contorted argument for why their data supported their original hypothesis. The paper probably shouldn’t have made it through to the scientific literature, and it certainly shouldn’t have made it to your Saturday breakfast reading. I don’t believe it and I’ll outline some reasons why below.The scientific paper and newspaper story point to a rising interest in epigenetics. This is a seductive but rather slippery word that has come to mean a variety of things in relation to how molecular structures close to DNA work, in particular modification of DNA bases by methylation. It is certainly exciting, and has become a leading mechanism to explain how the environment communicates with our genes. But it’s also easy to oversimplify, and has been set up by some people as an inaccurate alternative to genetics.

Making the weather in English writing and art
From icy ground gleaming in early literature to our idea of a data cloud … the portrayals of weather in different eras are full of surprisesOn the last night of the 18th century, the heroine of Virginia Woolf’s Orlando leans out from her London window. In the cool, clear air she surveys the smooth domes and magnificent vistas of the city. All is “light, order, and serenity”. But then, as she watches, a rapid gloom starts to close in. Within moments, there comes a dramatic meteorological alteration. “A turbulent welter of cloud covered the city. All was darkness; all was doubt; all was confusion. The 18th century was over; the 19th century had begun.”This is how time passes in Woolf’s historical pageant: the atmosphere of English life in different eras is established through changes in the air. It is a masterstroke of literalism. Life changes in accordance with the newly Victorian weather: skirts are worn to the ground and tablecloths follow suit; ivy grows in profusion; in the muffled gloom, evasions and concealments are bred almost as quickly as children. Continue reading...
Why don’t we take our own advice?
‘There’s a huge gulf between grasping something intellectually and really feeling it in your bones’“Why is it so hard to take your own advice?” the psychology writer Melissa Dahl asked in a New York magazine essay some months ago, and the question’s been bugging me ever since. I have the towering arrogance to imagine that if you followed some of the suggestions made each week in this column, you might be moderately happier or more productive, with a little less relationship drama, a little more inner calm. (From my email inbox, I know this happens at least occasionally.) But were you to infer from this that I follow such advice flawlessly myself, you’d be hilariously mistaken. When friends mention their difficulties with partners or bosses, Dahl wrote, she always tells them to talk to the person involved. Just say something! “And probably, this is good advice,” she mused. “I wouldn’t know, as it’s something I rarely do myself.” I can relate. I suspect most of us can. As the old wisecrack has it: “Take my advice – I’m not using it.”The cynical take on this is that we ignore our own advice because it’s rubbish: we dispense it to seem wise, when in fact it’s glib nonsense. (All exhortations to “try harder” or “snap out of it” or “look on the bright side” fall into this category: if the recipient could do so, he or she already would have, without your so-called help.)

Threat to oceans from climate change must be key to Paris talks, say scientists

Richard Dawkins interview: 'It must be possible to construct life chemically, or in a computer'
Richard Dawkins has always been a figure of controversy. Part two of his autobiography, now out, picks up from the publication of The Selfish Gene. A combative presence on Twitter, he is a surprisingly much quieter personality behind the scenes, writes Carole CadwalladrBritain’s most famous atheist is surprisingly low-key. The public Richard Dawkins – combative, outspoken, relentless – is, it turns out, a different beast from the private one.Anyone who’s witnessed a Dawkins intervention – on television, in print, or in 140 characters or fewer on Twitter – will have experienced him on fighting form: sure of his facts and opinions, unflinching in his deployment of both. In the flesh, in a room in New College, Oxford, his base for pretty much his entire working life (though he is now theoretically retired), he’s quieter, less bombastic, more human. He’s reflective, weighing up answers and expressing that most un-Dawkins-like sentiment: doubt. When I bring up his Twitter controversies, he cringes. It’s not deliberate, he says. “I genuinely and honestly don’t want to annoy people. I do want to clarify and it’s true that clarifying sometimes backfires, but my aim is always to clarify.” Continue reading...

Southern Ocean showing 'remarkable' revival in carbon absorption ability
Unexpected findings show oceans’ potential to absorb CO2 fluctuates more over time than previously thought, researchers sayThe Southern Ocean, which acts as one of the natural world’s most effective sponges for absorbing carbon dioxide, is showing signs of an unexpected revival in its ability to do so, according to scientists.The oceans absorb around a quarter of emissions caused by human activities, such as the burning of fossil fuels, reducing the speed of climate change. About 40% of this occurs in the Southern Ocean, which surrounds the Antarctic, making it the planet’s strongest ocean carbon sink.
'Small spelunkers required': the ad that led to the discovery of Homo naledi
