Monkey mariners made monumental migration 21 million years ago

By Will Dunham WASHINGTON (Reuters) - Monkeys resembling today's capuchins accomplished the astonishing feat of crossing at least 100 miles (160 km) of open ocean 21 million years ago to get from South America to North America eons before the two continents joined together. Scientists said on Wednesday they reached that conclusion based on the discovery of seven little teeth during excavations involving the Panama Canal's expansion, showing monkeys had reached the North American continent far earlier than previously known. South America at the time was secluded from other continents, with a strange array of mammals evolving in what 20th century American paleontologist George Gaylord Simpson called "splendid isolation." How Panamacebus performed the feat is a bit mysterious.

China to launch 'core module' for space station around 2018

China will launch a "core module" for its first space station some time around 2018, a senior official told the state-run Xinhua news agency on Thursday, part of the country's plan to have a permanent manned space station in service around 2022. Advancing China's space program is a priority for Beijing, with President Xi Jinping calling for the country to establish itself as a space power. The "core module" will be called the "Tianhe-1", the Chinese word for galaxy or Milky Way, Wang Zhongyang, spokesman for the China Aerospace Science and Technology Corp, told Xinhua.

Some Science Coming from Japan's Ailing Hitomi Satellite

Japan's troubled Hitomi satellite managed to collect some science data before going silent last month, scientists said. Officials haven't heard from the Hitomi X-ray astronomy satellite since late March, about six weeks after the satellite's launch, and the craft appears to have broken into several pieces. "I am aware of the situation right now with Hitomi," Hornschemeier said here Sunday (April 17), during a session at the American Physical Society's April Meeting.

Flexible Camera Wraps Around Objects to Capture 360-Degree Views

A new camera that looks like a flat sheet of paper is so thin and flexible that it could be wrapped around everyday objects, such as desks, cars, streetlights and even clothing, new research shows.

This 'Smart' Juicer Is Like a Keurig Machine for Juice

A glass of freshly squeezed juice certainly beats the mass-produced kind you'd buy off a store shelf — after all, it's both tasty and nutritious. Now, a company has developed a new high-tech juicer that can deliver fresh, organic juice with the simple push of a button. The new juice system, made by the company Juicero, operates much like a single-cup coffee brewing system, but for juice.

Google Celebrates National Park Week with Virtual Views

It's National Park Week, but for anyone who is stuck indoors and can't hit the road, Google is making it easy to virtually visit many of America's treasures. Google Street View and Google Cultural Institute have teamed up to showcase U.S. national parks and historic sites on one easy-to-navigate web page. Users can overlook the Merced River in Yosemite National Park in California, view volcanic cinder cones at Idaho's Craters of the Moon National Monument and take a virtual hike in the Everglades in Florida, among other virtual adventures.

South Africa boosts crop forecast accuracy with satellite imagery

By Ed Stoddard PRETORIA (Reuters) - South Africa's estimates for key crops such as maize have become increasingly accurate thanks to satellite imagery and as farmers' often biased input has been cut out of the picture, a conference was told on Thursday. South Africa's maize crop has been hard hit this season by a scorching drought, bringing into sharp focus the need for accurate forecasts of the harvest's size to guide government policy and markets. From 1997 to 2002, all of the maize forecasts made by the official Crop Estimates Committee (CEC) underestimated the size of the harvest, said Eugene du Preez, director of privately-held SiQ, which provides the committee with satellite and aerial data, which helps it determine the size of the area planted.

Longer Legs Linked to Cancer Risk

Colorectal cancer has been linked to a number of risk factors, such as inactivity, smoking and eating a lot of red meat. Now, a new study suggests a slightly more surprising risk factor: long legs. Compared with people who had shorter legs, those with longer legs had a 42 percent higher risk of developing colorectal cancer, according to the new study presented here today (April 19) at the American Association for Cancer Research's annual meeting.

Aspirin Linked to Lower Brain Cancer Risk

Taking aspirin regularly may reduce a person's risk for a certain type of brain cancer, a new study finds. In the study, researchers found that people who regularly took aspirin had a nearly 34 percent lower risk of a type of brain tumor called a glioma, compared with people who didn't take aspirin regularly. This is not the first study to look at the link between over-the-counter pain relievers and brain cancer risk.

How the Plants Around Your Home May Affect Your Life Span

Women in the study with the most greenness near their homes — whether it was plants, trees and other vegetation — had a 12 percent lower death rate during the study period, compared with women who had the least amount of vegetation near their homes, the researchers found. "It is important to know that trees and plants provide health benefits in our communities, as well as beauty," Linda Birnbaum, director of the National Institute of Environmental Health Sciences, which funded the study, said in a statement. For the study, researchers at the Harvard T.H. Chan School of Public Health and Brigham and Women's Hospital in Boston looked at the level of vegetation around the homes of about 110,000 women who were registered nurses living across the United States, and were participating in a large ongoing research effort called the Nurses' Health Study.

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.

Searching for the Vikings: 3 Sites Possibly Found in Canada

Three archaeological sites that may have been used by Vikings around 1,000 years ago were excavated recently in Canada. 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.

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.

'Extraordinary Find': Ancient Roman Villa Unearthed in Britain

One of Britain's best-preserved Roman-age villas was recently discovered beneath a home in southwest England. Homeowner Luke Irwin, who lives in Wiltshire, wanted to run electrical cables from his house to an old barn, where his children could play table tennis. "It was extraordinary," Irwin told Live Science.

How to Photograph Wildflowers

Bob Wick is a photographer and U.S. Bureau of Land Management (BLM) wilderness specialist. California's Carrizo Plain is an amazing canvas for wildflower photography. When conditions are right in the spring, numerous wildflowers can carpet the valley floor — and although they're short-lived, they can be breathtaking.

Moon Mosaics: Groundbreaking Science Images of Stunning Lunar Science (Op-Ed)

Mark Robinson is a professor in ASU's School of Earth and Space Exploration, LROC principal investigator, and a science team member on a number of missions including NEAR, CONTOUR, MESSENGER and Mars 2020. The Lunar Reconnaissance Orbiter (LRO) was conceived and designed a decade ago to support a human return to the moon. In late 2004 after a competitive process, NASA selected seven science instruments for the LRO, including the Lunar Reconnaissance Orbiter Camera, commonly known as LROC (pronounced EL-rock).

Collider Unleashed! The LHC Will Soon Hit Its Stride

Don Lincoln is a senior scientist at the U.S. Department of Energy's Fermilab, the United States' biggest Large Hadron Collider research institution. The world's largest particle accelerator, the Large Hadron Collider (LHC), is resuming operations after a pause during the winter months, when the cost for electricity in France is highest. So why is it such a big deal that LHC coming back on line?

Speedy eye-tracking device seeks to detect concussions

By Ben Gruber BOSTON (Reuters) - A newly-approved device using infrared cameras to track eye movements promises to help detect concussions in one minute, offering a speedy insight into whether athletes have sustained the injury. Boston-based neuro-technology company SyncThink got clearance from the U.S. Food and Drug Administration in February for its first device, "Eye-Sync", the first of its kind to get the green light from the authority amid growing concerns over brain injuries in contact sports. As the user follows the circle, the cameras follow the eyes and the data collected is compared against a baseline of normal eye movement for diagnosis.

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.

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.

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.

'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.

Your Genes May Influence When You Lose Your Virginity

Genetics may have a say in when people lose their virginity. "Clearly some of the things that impact the age of first sex are social," study co-author Felix Day, a genetics researcher at the University of Cambridge in the U.K., told Live Science.
