A Medieval Recipe Could Kill Hospital Superbugs. No, Really. 

Staph infections are one of the most pervasive and annoying bacterial infections faced by hospitals every year. It infects half a million people in the US every year, with symptoms ranging from skin infections to heart problems — and worse, some strains (commonly known as MRSA) have evolved to resist common antibiotics.

First Prototype of a Working Tricorder Unveiled At SXSW

the_newsbeagle writes The $10 million Tricorder X-prize is getting to the “put up or shut up” stage: The 10 finalists must turn in their working devices on June 1st for consumer testing. At SXSW last week, the finalist team Cloud DX showed off its prototype, which includes a wearable collar, a base station, a blood-testing stick, and a scanning wand. From the article: “The XPrize is partnering with the medical center at the University of California, San Diego on that consumer testing, since it requires recruiting more than 400 people with a variety of medical conditions. Grant Campany, director of the Tricorder XPrize, said he’s looking forward to getting those devices into real patients hands. ‘This will be a practical demonstration of what the future of medicine will be like, ‘ said Campany at that same SXSW talk, ‘so we can scale it up after competition.'” Read more of this story at Slashdot.

Hundreds Expelled, Many Arrested, For Cheating In India’s School Exams

Etherwalk writes Sources conflict, but it looks like as many as 300 people have been arrested for cheating in the Indian state of Bihar after the Hindustan Times published images of dozens of men climbing the walls of a test center to pass answers inside. 500-700+ students were expelled and police had been bribed to look the other way. Xinhau’s version of the story omits any reference to police bribery, while The ABC’s omits the fact that police fired guns into the air. Read more of this story at Slashdot.

Scientists Have Worked Out How Chameleons Change Color

The changing color of a chameleon’s body is an impressive sight—but how it happens has long been a significant scientific question without a compelling answer. Now, researchers have finally identified a thin layer of deformable nanocyrstals in their skin which gives rise the phenomenon. Read more…

The World’s Oldest Mummies Are Suddenly Turning Into Black Goo

Having survived 8, 000 years, the Chinchorro mummies found in modern-day Chile and Peru have started decaying more quickly than ever before—in some cases even melting into gelatinous “black ooze.” Scientists at Harvard think they’ve found the reason why. Read more…

Yik Yak Raises Controversy On College Campuses

HughPickens.com writes Jonathan Mahler writes in the NYT that just as Facebook swept through the dorm rooms of America’s college students a decade ago, the social app Yik Yak, which shows anonymous messages from users within a 1.5-mile radius is now taking college campuses by storm. “Think of it as a virtual community bulletin board — or maybe a virtual bathroom wall at the student union, ” writes Mahler. “It has become the go-to social feed for college students across the country to commiserate about finals, to find a party or to crack a joke about a rival school.” While much of the chatter is harmless, some of it is not. “Yik Yak is the Wild West of anonymous social apps, ” says Danielle Keats Citron. “It is being increasingly used by young people in a really intimidating and destructive way.” Since the app’s introduction a little more than a year ago, Yik Yak has been used to issue threats of mass violence on more than a dozen college campuses, including the University of North Carolina, Michigan State University and Penn State. Racist, homophobic and misogynist “yaks” have generated controversy at many more, among them Clemson, Emory, Colgate and the University of Texas. At Kenyon College, a “yakker” proposed a gang rape at the school’s women’s center. Colleges are largely powerless to deal with the havoc Yik Yak is wreaking. The app’s privacy policy prevents schools from identifying users without a subpoena, court order or search warrant, or an emergency request from a law-enforcement official with a compelling claim of imminent harm. Esha Bhandari, a staff attorney at the American Civil Liberties Union, argues that “banning Yik Yak on campuses might be unconstitutional, ” especially at public universities or private colleges in California where the so-called Leonard Law protects free speech. She said it would be like banning all bulletin boards in a school just because someone posted a racist comment on one of the boards. In one sense, the problem with Yik Yak is a familiar one. Anyone who has browsed the comments of an Internet post is familiar with the sorts of intolerant, impulsive rhetoric that the cover of anonymity tends to invite. But Yik Yak’s particular design can produce especially harmful consequences, its critics say. “It’s a problem with the Internet culture in general, but when you add this hyper-local dimension to it, it takes on a more disturbing dimension, ” says Elias Aboujaoude.” “You don’t know where the aggression is coming from, but you know it’s very close to you.” Read more of this story at Slashdot.

Nanotech Makes Steel 10x Stronger

An anonymous reader writes: A new metal-making process currently in testing at oil fields uses nano-scale plating to make metals like steel as much as ten times stronger than they would be without it. “[The process] uses an advanced form of electroplating, a process already used to make the chrome plating you might see on the engine and exhaust pipes of a motorcycle. Electroplating involves immersing a metal part in a chemical bath containing various metal ions, and then applying an electrical current to cause those ions to form a metal coating. The company uses a bath that contains more than one kind of metal ion and controls how ions are deposited by varying the electrical current. By changing the current at precise moments, it can create a layered structure, with each layer being several nanometers thick and of different composition. The final coating can be up to a centimeter thick and can greatly change the properties of the original material.” Read more of this story at Slashdot.

Researcher Developing Tattoo Removal Cream

BarbaraHudson writes During tattooing, ink is injected into the skin, initiating an immune response, and cells called “macrophages” move into the area and “eat up” the ink. The macrophages carry some of the ink to the body’s lymph nodes, but some that are filled with ink stay put, embedded in the skin. That’s what makes the tattoo visible under the skin. Dalhousie Uiversity’s Alec Falkenham is developing a topical cream that works by targeting the macrophages that have remained at the site of the tattoo. New macrophages move in to consume the previously pigment-filled macrophages and then migrate to the lymph nodes, eventually taking all the dye with them. “When comparing it to laser-based tattoo removal, in which you see the burns, the scarring, the blisters, in this case, we’ve designed a drug that doesn’t really have much off-target effect, ” he said. “We’re not targeting any of the normal skin cells, so you won’t see a lot of inflammation. In fact, based on the process that we’re actually using, we don’t think there will be any inflammation at all and it would actually be anti-inflammatory.” Read more of this story at Slashdot.

Facebook Will Soon Be Able To ID You In Any Photo

sciencehabit writes Appear in a photo taken at a protest march, a gay bar, or an abortion clinic, and your friends might recognize you. But a machine probably won’t — at least for now. Unless a computer has been tasked to look for you, has trained on dozens of photos of your face, and has high-quality images to examine, your anonymity is safe. Nor is it yet possible for a computer to scour the Internet and find you in random, uncaptioned photos. But within the walled garden of Facebook, which contains by far the largest collection of personal photographs in the world, the technology for doing all that is beginning to blossom.
