How to solve the maths puzzle for Vietnamese eight-year-olds that stumped parents and teachers
I set this maths puzzle yesterday. Now for the solution. It wasn’t pretty, folks, but we got there in the endThe challenge was to fill in the above snake with the digits 1 to 9, using each digit only once. The colon “:” means divide, and you must follow the standard order of operations, meaning that multiplication/division comes before addition/subtraction.Related: Can you do the maths puzzle for Vietnamese eight-year-olds that has stumped parents and teachers?

Study of attitudes to same-sex marriage retracted over 'fake data'
Prof Donald Green ‘embarrassed’ over claims of errors by his co-author in study that found a conversation with a gay canvasser could soften attitudesThe senior author of a study claiming to find that a brief, face-to-face conversation with a gay political canvasser had the ability to soften the opinions of those opposed to same-sex marriage has retracted its findings, claiming there were errors in his co-author’s work.The study, which was published in Science in December and was widely covered in the media, found support for same-sex marriage climbed among voters who had a single conversation with a gay or lesbian canvasser. In addition, the authors found that the changed views not only lasted for at least a year, but also positively influenced the opinions of other members of the household.(1/2) I read "Irregularities in LaCour (2014)," posted at http://t.co/SJ3jE89XeD on May 19, 2015 by Broockman et al.

Hard to bear: pandas poorly adapted for digesting bamboo, scientists find
Adding to their extinction woes, study finds pandas have a carnivorous digestive system and lack the gut flora for extracting maximum energy from plantsThe panda’s woes are well-documented. Their habitat is shrinking, they are incredibly fussy eaters and they have an unusually lacklustre approach to sex.Now scientists have discovered that the bears are also poorly adapted for digesting bamboo, despite the plant being almost the only thing they eat. The research shows that two million years after shifting to a herbivore lifestyle, the giant panda still has carnivore-like gut bacteria, which is better at breaking down protein. Continue reading...
Science on stage: should playwrights respect history and truth?
Critics of science plays cannot accept that playwrights are free to depict real historical events and people as they likeTheatre and science have had a long history together, but in recent decades there has been a sharp surge of interest in putting scientific ideas on the stage. Just this year two new “science plays” have premiered: Tom Stoppard’s The Hard Problem opened at the National Theatre in January, set in the high-pressured world of a cutting-edge brain research institute, and a few months later Tom Morton-Smith’s play Oppenheimer opened at the Royal Shakespeare Company and then transferred to the West End. It has been praised for merging “real” science, biography and history while not skimping on, or dumbing down, the scientific ideas it depicts.In contrast, several films that have had meaty scientific subjects like The Imitation Game, depicting Turing’s code-breaking efforts at Bletchley, or the Stephen Hawking biopic The Theory of Everything, have actually contained very little science and focused instead on biography.
Are we products of nature or nurture? Science answers age-old question
Twin studies collated over the past 50 years reveal human traits and disease are almost equally determined by genetic and environmental factorsThe age-old question of whether human traits are determined by nature or nurture has been answered, a team of researchers say. Their conclusion? It’s a draw.By collating almost every twin study across the world from the past 50 years, researchers determined that the average variation for human traits and disease is 49% due to genetic factors and 51% due to environmental factors.

Health and data: can digital fitness monitors revolutionise our lives?
From granular microchips to voice analysis, health-tracking technology offers medical benefits but doubt persist about the quality and security of data gatheredFrom the instant he wakes up each morning, through his workday and into the night, the essence of Larry Smarr is captured by a series of numbers: a resting heart rate of 40 beats per minute, a blood pressure of 130/70, a stress level of 2%, weight of 87kg, 8,000 steps taken, 15 floors climbed, eight hours of sleep.Smarr, an astrophysicist and computer scientist, could be the world’s most self-measured man. For nearly 15 years, the professor at the University of California at San Diego has been obsessed with what he describes as the most complicated subject he has ever experimented on: his own body.

Equality and polyamory: why early humans weren't The Flintstones
A study released last week presented evidence that prehistoric men and women lived in relative equality. But is the truth even further from the nuclear narrative?Last week, scientists from University College London released a paper presenting evidence that men and women in early society lived in relative equality. The paper challenges much of our understanding of human history, a fact not lost on the scientists. Mark Dyble, the study’s lead author, stated “sexual equality is one of the important changes that distinguishes humans. It hasn’t really been highlighted before.”Despite Dyble’s comments, however, this paper isn’t the first foray into the issue. In fact, it represents another shot fired in a debate between scientific and anthropological communities that has been raging for centuries. It’s a debate that asks some fundamental questions: who are we, and how did we become the society we are today?Related: Early men and women were equal, say scientistsRelated: Being polyamorous shows there's no 'traditional' way to live | Laurie Penny Continue reading...

The truth about poo: we’re doing it wrong
Who knew sitting on the toilet was bad for you? In her best-selling book Charming Bowels, microbiologist Giulia Enders explains how to go to the looIn my large Italian family, I grew up with the subject of poo, bottoms and constipation readily – and far too frequently – discussed at the dinner table. I’d be about to raise a raviolo to my mouth, only to hear how someone’s piles had popped, just that morning.This doesn’t mean I’m anal (sorry) about the subject. It’s fascinating away from the lunch table. Late last year, I read that we are pooing all wrong: we should be squatting, not sitting, on a toilet bowl. Then a book called Charming Bowels by Giulia Enders caused something of a storm in its native Germany and I got fully immersed in the subject. Continue reading...

'You think I'm mad?' – the truth about psychosomatic illness
Yvonne went blind overnight, Matthew couldn’t walk, Shahina lost the use of her hand – but doctors found nothing wrong. Were they faking it, or was the mind playing tricks? A neurologist on her most intriguing casesI was a junior doctor when I encountered Yvonne. She was 40 and worked in a supermarket. One Tuesday she was reorganising produce in a refrigerated unit while a colleague cleaned the glass. Yvonne turned to talk to her just as she released a small spray of window cleaner. Yvonne felt the liquid splatter on her face and a burning in both eyes. Another colleague led her to the bathroom and washed her eyes with water. Yvonne was taken by ambulance to hospital, where she was examined and had her eyes bathed. Her husband was called, and by the time he arrived she was feeling better. Her eyes were red and full of tears, but she could see normally and the pain had lessened. Her husband took her home.He told her not to go in to work the next day, and during the morning Yvonne noticed her vision blurring. By lunchtime, she was struggling to read the digital clock. Her husband and children came home that evening and encouraged her to have an early night. When Yvonne woke up and opened her eyes, everything was black. She cried out for help and heard the noise of people entering the room, but could not see them. She was completely blind.I noticed increasingly that when she spoke, she looked me in the eye. It was more than a glance; I felt our eyes connectDo you really think my daughter could hold her hand like this for weeks? She's in pain. I know my own childI can't believe it! I came to this hospital with muscle spasm and now I'm being told I'm doing it on purposeFantastic news: none of his tests had shown evidence of MS. I could see his face darken and his wife's eyes roll Continue reading...
Jane Hawking: ‘There were fourof usin our marriage’
Motor neurone disease and physics both played a part in her split from her husband Stephen Hawking, she says. She talks about the challenges they faced in their 30-year marriage and about how close The Theory of Everything was to realityHere is Stephen Hawking’s verdict on the movie about his marriage: it needed more science. And here is Jane Hawking’s verdict: it needed more emotion. Those opposing views on The Theory of Everything, which brought Eddie Redmayne an Oscar and a Bafta for his portrayal of Stephen and Felicity Jones Oscar and Bafta nominations for her portrayal of Jane, reveal a great deal about not only the personalities of the world’s most famous scientist and his former wife, but also one of the major strands of difference in their relationship.But the truth is that science is probably more absent from the film than emotion, because what the film represents is a triumph of Jane’s experience and persona after decades in which the family was viewed solely through the prism of Stephen’s genius, who as well as being the world’s best-known scientist is also the world’s best-known sufferer of motor neurone disease (MND).Related: Dear Katie Hopkins.
