When bar fights get mean, bystanders intervene Posted: 23 Jul 2013 12:50 PM PDT People are more likely to try to break up a bar fight when they believe the conflict is too violent, or has the potential to become more violent, according to researchers.

Sleep deprivation linked to aging skin, study suggests Posted: 23 Jul 2013 12:50 PM PDT In a first-of-its-kind clinical trial, physician-scientists found that sleep quality impacts skin function and aging. The study, commissioned by Estée Lauder, demonstrated that poor sleepers had increased signs of skin aging and slower recovery from a variety of environmental stressors, such as disruption of the skin barrier or ultraviolet (UV) radiation. Poor sleepers also had worse assessment of their own skin and facial appearance.

Athletes need to be careful to monitor diet, weight to maintain muscle mass Posted: 23 Jul 2013 10:45 AM PDT Athletes seeking a healthy performance weight should eat high fiber, low-fat food balanced with their training regimen in order to maintain muscle while still burning fat, according to a new article.

Optimists better at regulating stress Posted: 23 Jul 2013 10:45 AM PDT It's no surprise that those who tend to see a rose's blooms before its thorns are also better at handling stress. But science has failed to reliably associate optimism with individuals' biological stress response -- until now.

Why are sea stars dying from New Jersey to Maine? Divers asked to report large groupings of starfish Posted: 23 Jul 2013 10:42 AM PDT Marine biologists are working to identify the cause of a disease that is killing sea stars (starfish) from New Jersey to Maine.

We don't like unfamiliar music, even though we claim we do Posted: 23 Jul 2013 10:42 AM PDT Spotify. Pandora. iTunes. YouTube. We are constantly bombarded with a seemingly limitless amount of new music in our daily lives. But why do we keep coming back to that one song or album we couldn't get enough of in college? New research shows that although consumers say they prefer to listen to unfamiliar music, their choices actually belie that preference.

Going through the motions improves dance performance Posted: 23 Jul 2013 05:13 AM PDT Dance marking -- loosely practicing a ballet routine by "going through the motions" -- may improve the quality of dance performance by reducing the mental strain needed to perfect the movements, according to new research.

Major cities often safest places in the U.S. Posted: 23 Jul 2013 05:13 AM PDT Overturning a commonly-held belief that cities are inherently more dangerous than suburban and rural communities, researchers have found that risk of death from injuries is lowest on average in urban counties compared to suburban and rural counties across the US.
