Constraining choice isn't necessarily a good thing when it comes to managers' problem-solving, according to a new Canadian study. Managers tend to pick higher-risk options when forced to choose between competing alternatives to complex situations, according to researchers from the University of Guelph and University of Waterloo whose study was published recently in the Journal of Business Ethics. But when they're not forced to choose, managers tend to reflect more and solve problems with fewer negative consequences, says the study. "One of the most powerful tools ...

Forget digital fingerprints, iris recognition and voice identification, the next big thing in biometrics could be your knobbly knees. Just as a fingerprints and other body parts are unique to us as individuals and so can be used to prove who we are, so too are our kneecaps. Computer scientist Lior Shamir of Lawrence Technological University in Southfield, Michigan, has now demonstrated how a knee scan could be used to single us out. The approach based on MRI could be used to quickly register and identify people in a moving queue as they approach passport control at airports ...

COLUMBIA, Mo. — More than one-third of Americans are obese, and these individuals often experience accompanying health issues, such as Type 2 diabetes and cardiovascular problems. In response to the so-called "obesity epidemic," many medical professionals have suggested ways to improve the health outcomes of obese individuals through diet and exercise. Now, research conducted at the University of Missouri suggests certain exercises that benefit obese men may not have the same positive results for obese women. These findings could help health providers and researchers develop ...

The study took into account the state of different breeds, ...

New research by the University of Southampton has found a mechanism as to how corals use their pink and purple hues as sunscreen to protect them against harmful sunlight. Many reef corals need light to survive, as they benefit from sugars and lipids that are produced by their light-dependent symbiotic algae. However, in the shallow water of coral reefs, light levels are often higher than required by the corals, so paradoxically, the vital sunlight can become harmful for the algae and their hosts. Apart from temperature, light stress is a major driver of coral bleaching ...
