I DON’T WANT TO BE RIGHT: why do people persist in believing things that just aren't true? The New Yorker asks. Alternatively, a BBC Future author offers up some beguiling and subtle solutions in The best way to win an argument.
HP scaling memristor and photonic computing: "the device is essentially remembering 1s or 0s depending on which state it is in, multiplying its storage capacity. HP can build these chips with traditional semiconductor equipment and expects to be able to pack unprecedented amounts of memory—enough to store huge databases of pictures, files, and data—into a computer. In theory, that would remove the need for a conventional slow disk/fast memory system. With the Machine's main chips sitting on motherboards right next to the memristors, they can access any needed information almost instantly..." [more inside]

We have released 7 hoax videos which appear to demonstrate paranormal phenomena. In fact they're all based upon real scientific principles. Over the past few months this hoax footage has been posted all over the internet in an attempt to find out if people would either accept it as genuine or question it in an attempt to discover the real truth. Can you find the hoaxes before we reveal the secret science behind these scams?Ghost on film (4:28)

There is a place in Russia called the Kola Penninsula that is just a jump away from both Norway and Finland. At this remote locale, people can visit a crumbling cinder block building in the middle of nowhere that is surround by debris. Amongst this debris is a nondescript metal cap secured with a dozen rusting bolts. Beneath this cap is the deepest hole in the world. [more inside]
Humans have co-evolved with the resident microbes that call us "home", known as the microbiota, consisting of trillions of cells that colonize our bodies. The microbiota carry out many beneficial functions, such as producing vitamins, aiding in digestion, and protecting against invading microbes, but disruption from antibiotics or delivery by Caesarian section may have consequences for human health. Recently, antibiotic use has been linked with obesity and asthma. Using both human studies and experimentally observed mice, we are beginning to understand how antibiotics may lead to the disappearance of microbes and to identify key microbes that impact our health.[more inside]

The Journal of Interdisciplinary Science Projects has been tackling this and other vital subjects from the world of popular culture. As well as the Winnie the Pooh question, they consider whether Miley Cyrus really can come on like a wrecking ball, where a tiny frog gets the extra mass to turn into a human prince, Sherlock's ability to see dog hairs at a great distance, how many lies Pinocchio could tell before the weight of his enlarged nose caused his neck to snap and the feasibility of Gus Fring's last walk. Word of warning: they're all PDFs. [more inside]
Jeffrey Mogil’s students suspected there was something fishy going on with their experiments. They were injecting an irritant into the feet of mice to test their pain response, but the rodents didn’t seem to feel anything. “We thought there was something wrong with the injection,” says Mogil, a neuroscientist at McGill University in Montreal, Canada. The real culprit was far more surprising: The mice that didn’t feel pain had been handled by male students. Mogil’s group discovered that this gender distinction alone was enough to throw off their whole experiment—and likely influences the work of other researchers as well. [more inside]

Whether it's the constant fretting over Miley Cyrus' influence on school girls or the growing (and troubling) tradition of Purity Balls, it's clear that society has a fascination with young women's sexuality — especially when it comes to controlling it. But what are we actually teaching today's girls about sex? Fueled by outdated ideals of gender roles and the sense that female sexuality is somehow shameful, there seem to be certain pernicious myths about girls and sex that just won't die. That sex education in America has gaping holes in its curriculum hasn't helped much, either; in a recent Centers for Disease Control (CDC) report just 6 out of 10 girls said that their schools' sex ed program included information on how to say no to sex. This lack of personal agency was reflected in a forthcoming study by sociologist Heather Hlavka at Marquette University as well, which found that many young girls think of sex simply as something that is "done to them." Knowledge is power, and we can promote a healthier relationship with sex by encouraging a more open dialogue, teaching girls to feel comfortable with their sexuality and, most importantly, emphasizing that their bodies are theirs and theirs alone.

The American Museum of Natural History will unlock thousands of old photos from their vault, they announced this week. The new online image database (officially launching on Monday the 28th) will take you behind the curtain, delivering images that span the 145-year history of the Museum. The collection features over 7,000 images—many never before seen by the public—and includes photos, rare book illustrations, drawings, notes, letters, art, and Museum memorabilia. They say "it’s like stepping into a time machine and seeing a long ago NYC or just catching glimpses of ghosts from a forgotten world now seen only by researchers and Museum staff." Previously.

Can you ever be reasonably sure that something is random, in the same sense you can be reasonably sure something is not random (for example, because it consists of endless nines)? Even if a sequence looked random, how could you ever rule out the possibility that it had a hidden deterministic pattern? And what exactly do we mean by “random,” anyway?

Most of these bacteria were benign at some point in their evolutionary past, and we don’t always understand what turned them into disease-causing pathogens. In a new study, researchers have tracked down when this switch happened in one flesh-eating bacteria. They think the knowledge might help predict future epidemics. [more inside]

Four women have had new vaginas grown in the laboratory and implanted by doctors in the US. "A tissue sample and a biodegradable scaffold were used to grow vaginas in the right size and shape for each woman as well as being a tissue match. They all reported normal levels of "desire, arousal, lubrication, orgasm, satisfaction" and painless intercourse. Experts said the study, published in the Lancet, was the latest example of the power of regenerative medicine. "

Harvard University and XVIVO have come together again (Previouslyw/ a commercial focus, Previouslierw/an Academic focus) to add to the growing series of scientific animations for BioVisions -- Harvard's multimedia lab in the department of Molecular and Cellular Biology. 'Protein Packing' strives to more accurately depict the molecular chaos in each and every cell, with proteins jittering around in what may seem like random motion. Proteins occupy roughly 40% of the cytoplasm, creating an environment that risks unintentional interaction and aggregation. Via diffusion and motor protein transport, these molecules are directed to sites where they are needed.

Ben Goldacre, The Guardian: "Today we found out that Tamiflu doesn't work so well after all. Roche, the drug company behind it, withheld vital information on its clinical trials for half a decade, but the Cochrane Collaboration, a global not-for-profit organisation of 14,000 academics, finally obtained all the information. Putting the evidence together, it has found that Tamiflu has little or no impact on complications of flu infection, such as pneumonia." [more inside]
