Half Australia's Great Barrier Reef coral 'dead or dying': scientists

By Colin Packham SYDNEY (Reuters) - Australian scientists said on Wednesday that just seven percent of the Great Barrier Reef, which attracts around A$5 billion ($3.90 billion) in tourism every year, has been untouched by mass bleaching that is likely to destroy half the coral. In the northern Great Barrier Reef, it's like 10 cyclones have come ashore all at once," said Professor Terry Hughes, conveyor of the National Coral Bleaching Taskforce, which conducted aerial surveys of the World Heritage site. "Our estimate at the moment is that close to 50 percent of the coral is already dead or dying," Hughes told Reuters.

'Magic Mushroom' Drug Psilocybin May Ease Pain of Rejection

During this game, people reported feeling less social pain when they received psilocybin, compared with when they received a placebo, or "dummy pill." In addition, participants' brain scans showed less activity in brain regions linked with feelings of social pain after they took psilocybin compared with after taking a placebo. Such treatments could be important for people with certain psychiatric disorders, who often encounter social rejection, and who may react more strongly to rejection than a healthy person, which can worsen mental health, the researchers said. "Social ties have repeatedly been shown to be crucial for physical and mental health," the researchers, from the University of Zurich in Switzerland, wrote in their findings published today (April 18) in the journal Proceedings of the National Academy of Sciences.

Eating Nuts Linked to Lower Risk of Colon Cancer

Now, new findings from South Korea suggest that a nut-rich diet may also reduce a person's risk of colon cancer. Eating a serving of nuts three or more times a week appeared to have a big effect on risk, said Dr. Aesun Shin, an associate professor of preventive medicine at Seoul National University College of Medicine in South Korea and an author of the study. This may be due to the availability of peanuts in South Korea, the researchers said.

Earthquakes in Japan and Ecuador Aren't Related: Here's Why

They may have happened within days of one another, but the devastating earthquakes in Japan had nothing to do with the strong temblor that struck Ecuador over the weekend, experts say. Both Japan and Ecuador are located along the so-called Pacific Ring of Fire, which spans the coasts lining the Pacific Ocean. The regions along the Ring of Fire are prone to earthquakes, but it's extremely rare for an earthquake on one side of the world to trigger earthquakes on the other, said Ross Stein, CEO and co-founder of Temblor.net, a free website and smartphone application that helps people understand locations' seismic risk.

Ultrathin 'E-Skin' Turns Your Hand into an Electronic Display

Your smartphone could one day be replaced by an electronic display laminated to the back of your hand, if the inventors of a new ultrathin "e-skin" have their way. For the first time, Japanese scientists have demonstrated a superflexible electronic skin (or e-skin) display, made from organic electronics, that doesn't degrade when exposed to air. Organic electronics, made from carbon-based polymers, hold huge promise for wearable devices because they are far lighter and more flexible than traditional electronics made from inorganic materials, such as silicon and gold.
