	(Sponsor this newsletter) 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.

If confirmed, the discoveries would add to the single known Viking settlement in the New World, located at L'Anse aux Meadows on the northern tip of Newfoundland. Excavated in the 1960s, that Viking outpost was used for a short period of time around 1,000 years agoas well. Read More » What Causes Eerie Volcanic Lightning? At nighttime, ominous lightning flashes above erupting volcanoes light up the sky like a living nightmare. Now, scientists are closer to understanding volcanic lightning, which stems from both ash and ice, two new studies reveal. In thunderstorms, the culprits are colliding ice crystals, which generate enough of an electric charge to trigger lightning.

	(Sponsor this newsletter) Ikea's New Chainless Bike Never Rusts Dealing with a rusty bicycle chain can be a messy affair, but an innovative new bike from Ikea solves that pesky problem. The furniture retail giant recently introduced its new "Sladda" bike, which uses an oil-free and corrosion-resistant drive belt rather than a metal chain. The drive belt is designed to last about 9,320 miles (15,000 kilometers), which is about two to three times longer than a typical steel chain, according to Ikea. Read More » 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. Read More » 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. Read More » '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. Read More » 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.

"These might be the remains of people who were part of this coup in Athens in 632 [B.C.], the Coup of Cylon," said Kristina Killgrove, a bioarchaeologist at the University of West Florida, in Pensacola, who was not involved in the current study. The mass grave was uncovered as archaeologists were excavating a huge cemetery in the ancient port city of Phaleron, just 4 miles (6.4 kilometers) from Athens.

In what was widely seen as a key milestone for artificial intelligence (AI) researchers, one system beat a former world champion at a mind-bendingly intricate board game. In early March, a Google-made artificial intelligence system beat former world champ Lee Sedol four matches to one at an ancient Chinese game, called Go, that is considered more complex than chess, which was previously used as a benchmark to assess progress in machine intelligence.

The Wright brothers didn't wait for the patent to be granted to take flight. On Dec. 17, 1903, the brothers lofted their flying machine into the air for 12 seconds, flying 120 feet at Kitty Hawk, on North Carolina's Outer Banks. Read More » Does The Full Moon Make Kids Hyper? Here's What Science Says Kids really do sleep less when there's a full moon, but only by a few minutes, according to a new study that included children from a dozen countries. What's more, the study failed to find a link between the occurrence of the full moon and kids' activity levels, debunking the myth that kids are more hyper during a full moon. The study "provides solid evidence … that the associations between moon phases and children's sleep duration/activity behaviors are not meaningful from a public health standpoint," the researchers, from the Children's Hospital of Eastern Ontario Research Institute in Ottawa, Canada, wrote in the March 24 issue of the journal Frontiers in Pediatrics.

People who eat fast food may be ingesting potentially harmful chemicals called phthalates, a new study finds — another reason to avoid eating these typically unhealthy foods, experts say. However, experts emphasize that most Americans are exposed to phthalates every day, and it's not clear exactly how much of this exposure comes from fast food. Still, for people who want to reduce their exposure to phthalates, a chemical used in plastics that can leach into foods, reducing fast food consumption could be one way to do this, said Dr. Kenneth Spaeth, chief of occupational and environmental medicine at Northwell Health, a health care network headquartered in Great Neck, New York.

The seven-meter high metal sculpture named "Unbearable" depicts a graph of carbon dioxide accumulation in the atmosphere sky-rocketing into the belly of a polar bear, gutting its abdomen and almost penetrating the back of the beast. Polar bears are among the animal species most threatened by the increase in global temperatures. Read More » Why Do So Many Earthquakes Strike Japan? A magnitude-7.0 earthquake struck southern Japan today, less than two days after a 6.2-magnitude temblor rocked the same region, triggering tsunami advisories in the area. The most recent earthquake struck the Kumamoto region on Japan's Kyushu Island early Saturday (April 16) at 1:25 a.m. local time (12:25 p.m. ET on April 15), according to the U.S. Geological Survey (USGS). With residents of the Kumamoto region reeling from two sizable earthquakes in as many days, and with memories of the massive 9.0-magnitude earthquake and tsunami that devastated Tohoku, Japan, in 2011 not far from people's minds, what is it about this part of the world that makes it so seismically active? Read More » Experimental inflatable module attached to space station By Irene Klotz CAPE CANAVERAL, Fla (Reuters) - A NASA ground-control team on Saturday used a robot arm to unpack an expandable module and attach it to the International Space Station, setting the stage for a novel test of a habitat for astronauts, researchers and even tourists. The 3,100-pound (1,400 kg) module, manufactured and owned by Bigelow Aerospace, was launched aboard a SpaceX Dragon cargo capsule that reached the station on Sunday.    The module was attached to the station at 5:36 am EDT (0936 GMT) as the station flew about 250 miles (400 km) above Earth, the U.S. space agency said during a live broadcast on NASA TV. The Bigelow Expandable Activity Module, or BEAM, is scheduled to be inflated with air in late May, beginning a two-year experiment to see how it holds up in the harsh environment of space.
