New system traces the origins of marine creatures
Tracing the origins of marine animals can be extremely difficult, especially in the free-flowing, soup-like conditions of the ocean, but obtaining this information is vital not only for understanding these organisms but for managing and conserving them as well. Scientists at Scripps Institution of Oceanography at UC San Diego have developed a novel approach for tracing the life roots of marine larvae, some of the most difficult organisms to track due to their microscopic sizes.
Researchers find surprising pattern of influenza spread in south america and tropics
Researchers studying influenza transmission patterns in the Southern Hemisphere and in tropical areas, specifically Brazil, uncovered the unexpected finding that each season influenza travels from low populated regions near the equator to the more populated centers. Their work, funded by the Fogarty International Center (NIH), part of the National Institutes of Health (NIH), can improve planning for influenza control in tropical areas.
Sleep found to repair and reorganize the brain
Most of us do it every night but we don't know why. If you miss too many nights, it might kill you.
Put on a happy face: happy digital characters sell products better than sad ones
Even in the digital world, people respond to the expression of a computerized face.
Robotic brace aids stroke recovery
At age 32, Maggie Fermental suffered a stroke that left her right side paralyzed. After a year and a half of conventional therapy with minimal results, she tried a new kind of robotic therapy developed by MIT engineers.
The answer to childhood obesity: kick a football around for 15 minutes a day?
Everyone knows children are getting fatter and that both a poor diet and a lack of exercise are to blame. But, what researchers have been unable to discover until now, is exactly how major a role activity plays in the battle to keep obesity at bay.
Mit neuroengineers' pulsing light silences overactive neurons
Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease.
Magnetic system could be key to surgery without scars
Physicians at UT Southwestern Medical Center and engineers at UT Arlington have collaborated to invent a groundbreaking system that could be key to delivering on the promise of surgery without scars.
Love not in the stars
Lonely hearts who turn to horoscopes to find their perfect partner are wasting their time, according to the largest test of astrology ever carried out.
Scientists explain why we vary in attractiveness
Newcastle University researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different?

Natural polyester makes new sutures stronger, safer
With the help of a new type of suture based on MIT research, patients who get stitches may never need to have them removed.
Practicing tai chi boosts immune system in older adults
Tai chi chih, the Westernized version of the 2,000-year-old Chinese martial art characterized by slow movement and meditation, significantly boosts the immune systems of older adults against the virus that leads to the painful, blistery rash known as shingles, according to a new UCLA study.
Procedure predicts embryos most likely to result in pregnancy
To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF.
Genes found for successful smoking cessation
Physicians may some day have a new tool for tailoring smoking cessation treatments to a patient's individual genetic makeup.
Stop signs: study identifies braking mechanism in the brain
As wise as the counsel to "finish what you've started" may be, it is also sometimes critically important to do just the opposite – stop. And the ability to stop quickly, either to keep from gunning the gas when a pedestrian steps into your path or to bite your tongue mid-sentence when the subject of gossip suddenly comes into view, may depend on a few "cables" in the brain.
Dieting does not work
Will you lose weight and keep it off if you diet? No, probably not, UCLA researchers report in the April issue of American Psychologist, the journal of the American Psychological Association.
Dairy, fruits and veggies may help smokers quit
Milk does the body good -- and may help smokers break the habit, say researchers at Duke University Medical Center.
Computer model mimics blink of a human eye
Computers can usually out-compute the human brain, but there are some tasks, such as visual object recognition, that the brain performs easily yet are very challenging for computers. To explore this phenomenon, neuroscientists have long used rapid categorization tasks, in which subjects indicate whether an object from a specific class (such as an animal) is present or not in the image.
Alma to help solving acute mountain sickness mystery
The Atacama Large Millimeter/submillimeter Array (ALMA) astronomical project will not only enlarge our knowledge of the vast Universe beyond the imaginable. It will also help scientists learn more about the human body.
Remote sheep population resists genetic drift
A wild sheep population on a remote Indian Ocean island is causing a stir among genetic researchers.
