Philosophy of the Large Hadron Collider | Michael Krämer | Life & Physics
There have been many tedious discussions about the value of philosophy for modern science. I find it much more interesting to ask if and in what way modern science can advance philosophyThe Large Hadron Collider (LHC) at the European Organization for Nuclear Research CERN in Geneva is the world’s largest and most powerful particle accelerator and possibly the most complex scientific instrument ever built. The LHC has just begun its second three-year run, at the record-breaking collision energy of 13 TeV. About 10,000 scientists from 60 countries will search for new phenomena beyond the Standard Model of particle physics, in pursuit of a simple, beautiful and all-encompassing theory of nature.Related: Live webcast of the 13 TeV restart of the CERN Large Hadron Collider Continue reading...
Are we really wrong to blame processed food for the rise in allergies? | Joanna Blythman
Sense About Science talks about ‘perceived food allergies’. But I’m not just another muesli-belt middle-class neurotic who doesn’t understand scienceOn the bus the other day I watched a mother hand her toddler a packet of salt and vinegar crisps. The little girl obviously liked them, doubtless relishing their salty-sweet crunch, but suddenly her face reddened, her eyes watered and she began coughing and spluttering, an episode that must have lasted a good two minutes. The volatile pungency of the crisps was getting up my nose a couple of seats away, so was it any wonder that a child’s immature lungs reacted like that?Related: Why does the media have a blindspot on food science? | Robin Bisson Continue reading...
Spectacular new species of waterlily discovered in Australia
Scientists from Kew and Western Australia stumbled upon the as yet unnamed flower during a three week expedition to collect waterlily specimensA perilous expedition in northwestern Australia that had researchers wading through lakes, ponds and creeks stalked by meat-eating crocodiles has ended with the discovery of a stunning new species of waterlily.
Newly discovered vessels beneath skull could link brain and immune system
Decades of textbook teaching could be overturned by discovery, which might also explain links between poor health and brain disorders such as Alzheimer’sScientists have discovered a previously unknown link between the brain and the immune system that could help explain links between poor physical health and brain disorders including Alzheimer’s and depression.The discovery of vessels, nestled just beneath the skull, overturns decades of textbook teaching and could pave the way for new approaches to treating brain diseases. The scientists behind the discovery described their surprise at having uncovered a major anatomical structure that until now had been entirely overlooked. Continue reading...

Solar power to the people: how the sun can ease Africa's electricity crisis
The scale of the continent’s energy deficit often fuels a sense of fatalism and paralysis. Yet on the flipside of this crisis are enormous opportunities“We shall make electric light so cheap that only the wealthy can afford to burn candles,” said Thomas Edison, inventor of the modern lightbulb. That was almost a century and a half ago.

Regaliceratops 'Hellboy' dinosaur discovered in Canada - video report
A new species of dinosaur has been discovered in Canada, nicknamed Hellboy because of regaliceratops' resemblance to the comic book character. It has short horns over its eyes and a long nose horn, unlike the features of close relative triceratops. The near-complete skull of the 70-million-year-old beast was spotted by chance 10 years ago, protruding from a cliff that runs along the Oldman river south of Calgary in Alberta Continue reading...

New dinosaurian royalty crowned - meet Regaliceratops
Horned dinosaur from Canada sports a ‘crown’ on the frill and reveals a unique evolutionary patternTyrannosaurus is known as the tyrant king, but palaeontologists have generally refrained from naming other dinosaurian royalty until now. Regaliceratops whose name translates as ‘royal horned face’ is a horned dinosaur from Alberta, Canada and has been named in a paper published last night. Like all of the horned dinosaurs, it has a number of horns on its face but also sports a frill of bone extending from the back of the skull that fans out behind the head. In Regaliceratops this frill is both large and has unusual pentagonal plates arranged around the edge, giving it something of a crown-like appearance. The name also commemorates the fact that 2015 marks the 30th anniversary of the opening of the Royal Tyrrell Museum of Palaeontology in Alberta where the specimen resides.

New species of dinosaur, the regaliceratops, discovered in Canada
Nicknamed Hellboy, the dinosaur had short horns over the eyes and a long nose horn, the opposite of the features sported by its close relative triceratopsWhen fossil experts first clapped eyes on the skull, it was clearly from a strange, horned dinosaur. When they noticed how stunted the bony horns were, its nickname, Hellboy, was assured.

How scientifically accurate is San Andreas? Rock solid or a bit faulty?
Dwayne Johnson’s disaster drama might have other films quaking in their boots at the box office, but there are seismic cracks in its geological accuracy, writes a professor of earthquake engineeringFirst of all, San Andreas is a fun film. It’s interesting. But it has a bit of a fatalistic scenario of destruction – one we hope will never actually happen – and the film makes several scientific errors.Related: The word from Hollywood: sensible is the new sexy | Catherine Shoard Continue reading...

The Undercurrent: why are we being fed by a poison expert? Monsanto and Roundup – video
The Undercurrent delves into the world of mass agriculture to ask how one company has such huge control over the world's food supply. The name Monsanto was once synonymous with Agent Orange, but in today's world it's the dominance of the widespread pesticide Roundup which helps keep the company on top of the pile. But is the World Health Organisation's claim that Roundup 'probably' causes cancer, cause for concern? And what about the company's stance on patenting which sees farmers in developing countries unable to hold on to their seeds for the next season? Guardian Australia has joined forces with The Undercurrent – an online news show billing itself as an antidote to the five-second soundbite – for a four-part series over June and July. Brisbane creators Jen Dainer and Dan Graetz say it is the show they wish existed – so they created it themselves Continue reading...

Breast cancer screening cuts chance of dying from disease by 40%, say experts
However, critics suggest panel may be over-stating effectiveness of screening as debate over exact value of mammograms continuesWomen who undergo breast cancer screening cut their risk of dying from the disease by 40%, according to a global panel of experts attempting to end a long-running controversy about mammograms.IARC, the International Agency for Cancer Research, an arm of the World Health Organisation, has weighed in with strong support for mammography screening, which has divided scientific opinion in recent years. Some scientists argue that few lives are saved and that screening does harm by identifying some small slow-growing cancers which are then treated with surgery, radiotherapy and drugs, but which would never have disturbed the woman in her lifetime.

The ‘choices’ facing women who want children | Letters from Dr Geeta Nargund and others
Harriet Minter writes (2 June, theguardian.com), of my campaign to see fertility issues added to the secondary school curriculum, that “the last thing we need is more scaremongering”. I am delighted that my call for fertility education has provoked such a widespread response. But this storm of opinion must not cloud focus on the underlying facts, and we need to correct some misconceptions and inaccuracies in media reporting.Harriet writes: “If you’re someone who is relatively fertile, your chances of having a baby in your 30s, or even your 40s, are not significantly lower than they would have been when you were younger.” This is inaccurate and references an article by Twenge in The Atlantic that itself misinterprets two important scientific papers. The first by Dunson and colleagues demonstrates significant reductions in a woman’s fertility with age. A second study by Rothman and colleagues shows that a couple’s fertility peaks around 30 years and at age 40 declines by approximately half with most of this decline attributable to the female partner. Both these complex academic studies clearly confirm the decline in fertility in women (and to a lesser extent men) over the age of 35. Continue reading...

Genetics plays role in deciding at what age women have first child, says study
Delayed motherhood has often been ascribed to sociological factors, but new findings show a genetic component, which also links to number of childrenWomen are starting families later in life despite an apparently stronger genetic drive to have children when they are younger, according to Oxford researchers.The team arrived at the conclusion after studying the DNA of nearly 7000 women and working out how large a role genetics plays in the age at which women start a family and the number of children they have.

We shouldn’t focus on assisted dying, but rather help others find value in life | Andrew Brown
Stephen Hawking’s restated position on assisted dying poses important questions about how the rest of us mere mortals gain a sense of self-worthWhat’s a life worth, and to whom? Professor Stephen Hawking has said once more that he would consider ending his life if he felt he could no longer make a contribution to the world; and although it’s obvious that he means by the world his loved ones as well as the theoretical physics community, it does seem a high bar to set. Not many of us are much use to the world as a whole; almost everyone has a job in which they could be replaced without too much strain and that may nowadays disappear without warning.Related: Stephen Hawking: 'I would consider assisted suicide' Continue reading...

The sawfish virgin births are not unnatural – they are a survival strategy | Aarathi Prasad
Many tiny species reproduce without sex, but in the case of these larger, endangered creatures, it is inbreeding born from necessityThe news this week that sawfish have been found to have had virgin births in the wild is not a niche occurrence. For many of the planet’s animal species, reproduction is not always what it seems. Some, such as bdelloid rotifers have successfully reproduced for millions of years without sex. In others, such as stingless wasps, little fire ants and some fish, the need for sex to reproduce and even their gender, can be changed by fungal infection or bacteria.Related: Sex and the sawfish: the world of wildlife virgin births Continue reading...
Chimps like chips. They would be cooking if they could
Chimpanzees prefer their vegetables lightly roasted. Clever experiments reveal that if our closest living relatives could only control fire they would probably be cookingAs far as we can tell, chimps don’t cook. Yet a series of clever experiments show that Pan troglodytes have a taste for cooked food and the cognitive capabilities to cook. The implication is that the common ancestor of chimps and humans that lived around 2 million years ago was poised to cook. The lineage that led to humans figured out how to control fire. The chimp lineage did not.The Guardian’s science correspondent Hannah Devlin has already written an excellent article about the research, but I thought I’d share with you some of the video clips that accompany the study, published today in Proceedings of the Royal Society.

Why do we dream? You asked Google – here's the answer | David Shariatmadari
Every day, millions of people ask Google some of life’s most difficult questions. In this series, our writers answer some of the most common queriesMaybe we should ask the duck-billed platypus.Back in the 1950s, scientists working on humans identified a state marked by increased brain activation, accelerated breathing and heart rate, and muscular paralysis. But perhaps the most remarkable feature was a flickering of the eyes beneath closed eyelids – because all these physiological changes took place while the subjects were fast asleep.

Most dinosaurs had scales, not feathers, fossil analysis concludes
Despite recent theories suggesting a common feathered ancestor or proto-feathers on all dinosaurs, new survey confirms that scales were the normResearchers have called time on a growing suspicion that many dinosaurs were not the dry, scaly animals of popular conception, but fluffy, feathered beasts instead.Remains unearthed in recent years have revealed feathers or proto-feathers on a range of dinosaurs, leading some paleontologists to wonder if all of the animals evolved from a feathered ancestor and sported some kind of plumage themselves.
