Moderate Drinking Has No Health Benefits, Large Review of Studies Concludes

Researchers reviewed 87 studies that found a link between moderate drinking and longevity, and they found major problems with way the studies were designed. "From a scientific standpoint, the relationship between alcohol consumption and health is obviously very important, and is a very controversial area," Dr. Tim Naimi, a physician and researcher at Boston Medical Center and co-author of the new review, told Live Science.

Mindfulness Meditation May Reduce Low Back Pain

People with chronic low back pain may benefit from meditating, a new study finds. In the study, a group of people with chronic low back pain participated in an eight-week program called mindfulness-based stress reduction, which involved using meditation to increase their awareness of the present moment, and their acceptance of difficult thoughts and feelings, including their pain. About six months after the start of the study, the people who participated in the meditation program were more likely to experience at least a 30 percent improvement in their ability to carry out daily activities, compared with the people who received only standard treatments for low back pain, such as medication.

'Japanese Diet' Linked to Longer Life

Eating the traditional Japanese diet may lead to a longer life, a new study finds. Adults in Japan who closely followed that country's government-recommended dietary guidelines had a 15 percent lower risk of dying during a 15-year time period, as compared to people who didn't follow the guidelines, according to the new study. In particular, those people who most closely followed the dietary guidelines were 22 percent less likely to die of stroke during the time period, according to the study, published today (March 22) in The BMJ.

Wireless mice leave billions at risk of computer hack: cyber security firm

By Ben Gruber San Francisco, CA (Reuters) - Marc Newlin and Balint Seeber are checking how far apart they can be while still being able to hack into each other's computers. It turns out its pretty far - 180 meters - the length of a city block in San Francisco.  The pair work for Bastille, a startup cyber security company that has uncovered a flaw they say leaves millions of networks and billions of computers vulnerable to attack.  Wireless mice from companies like HP, Lenovo, Amazon and Dell use unencrypted signals to communicate with computers.  "They haven't encrypted the mouse traffic, that makes it possible for the attacker to send unencrypted traffic to the dongle pretending to be a keyboard and have it result as keystrokes on your computer.

Holy Drones, Batman! Real-Life 'Batplane' Mimics Flexible Wings

Inspired by the wings that allow bats to pull off such impressive maneuvers, a team of engineers designed new kinds of wing surfaces for drones. At the University of Southampton in the United Kingdom, a group led by engineering professor Bharathram Ganapathisubramani designed a flexible, membrane wing for small drones, otherwise known as micro air vehicles (MAVs). MAVs are used for a variety of purposes, including reconnaissance and scientific work.

Birds Use Alligators As Bodyguards

Birds may use alligators as bodyguards to protect their nests from hungry raccoons and opossums, but gator payment may come at a steep cost — namely, in the form of the birds' chicks that are dropped into the water, researchers say. Previous research found that wading birds — such as storks, herons, egrets, ibises and spoonbills — often choose to nest above alligators. However, there was little research into what, if anything, alligators gained from such arrangements.

Butchered Bear Pushes Back Human Arrival on Ireland

The slashed kneecap of a bear found deep inside a prehistoric cave suggests human hunters lived in Ireland earlier than had been previously thought, a new study finds. Researchers found the kneecap in Ireland's Alice and Gwendoline Cave, in County Clare, in 1903. Then, in 2010 and 2011, Ruth Carden, an animal osteologist at the National Museum of Ireland, began going through the cave's many bone artifacts.

Trippy! Psychedelic Zebrafish Reveal How Cells Regenerate

In what looks more like a post-impressionist painting than a scientific achievement, a transgenic zebrafish is revealing how hundreds of its cells regenerate in a bouquet of colors. Scientists genetically programmed every cell on the zebrafish's body surface, including its cornea, scales, fins and barbels, to express a unique combination of green, red and blue fluorescent proteins, according to lead scientist Kenneth D. Poss, a cell biology professor at Duke University. The result: images of a technicolored zebrafish — revealing 70 different hues — that could just as easily hang in an art museum as appear in a scientific journal.
