Turtles and dinosaurs: Scientists solve reptile mysteries with landmark study on the evolution of turtles

Posted: 24 Nov 2014 07:32 AM PST

A team of scientists has reconstructed a detailed 'tree of life' for turtles. Next generation sequencing technologies have generated unprecedented amounts of genetic information for a thrilling new look at turtles' evolutionary history. Scientists place turtles in the newly named group 'Archelosauria' with their closest relatives: birds, crocodiles, and dinosaurs.

Trouble with your boss? Own it

Posted: 21 Nov 2014 07:28 AM PST

Don't get along with your boss? Your job performance may actually improve if the two of you can come to grips with the poor relationship. "Seeing eye-to-eye about the employee-supervisor relationship is equally, if not more important than the actual quality of the relationship," said the lead investigator on the study.

Life's extremists, a family of microbes called Archaea, may be an untapped source of new antibacterial drugs. That conclusion arises from the discovery of the first antibacterial gene in this ancient lineage.

Brain training using sounds can help aging brain ignore distractions

Posted: 20 Nov 2014 09:31 AM PST

As we age, we have an increasingly harder time ignoring distractions. But new research reveals that by learning to make discriminations of a sound amidst progressively more disruptive distractions, we can diminish our distractibility. A similar strategy might also help children with attention deficits or individuals with other mental challenges.

Weight, eating habits in Parkinson's disease

Posted: 20 Nov 2014 05:21 AM PST

A review of the scientific literature on Parkinson's disease shows that even the non-motor symptoms associated with the disease can contribute to the changes in body weight seen in patients (including those subjected to deep brain stimulation). Among the factors affecting eating habits and body weight there could be, for example, an impaired ability to derive pleasure from food and changes in motivation. These are important findings which can help to understand how to reduce these effects of Parkinson's that exacerbate an already negative clinical situation.

What's behind our music tastes? Some common perceptions

Posted: 20 Nov 2014 05:19 AM PST

Metal heads, jazz purists and folkies may have more in common musically than you imagined. A new study sheds light on the shared ways in which humans perceive music.

As elephants go, so go the trees

Posted: 18 Nov 2014 09:45 AM PST

Overhunting has been disastrous for elephants, but their forest habitats have also been caught in the crossfire. A first-of-its-kind study shows that the dramatic loss of elephants, which disperse seeds after eating vegetation, is leading to the local extinction of a dominant tree species, with likely cascading effects for other forest life.

New clue in celiac disease puzzle: Cause of oat toxicity explained

Posted: 18 Nov 2014 07:55 AM PST

Researchers have identified why some people with celiac disease show an immune response after eating oats. The researchers have identified the key components in oats that trigger an immune response in some people with celiac disease. The findings may lead to better tests for oat toxicity, and have implications for new treatments being developed for celiac disease.

Whole-genome sequences of the world's oldest living people: No genes significantly associated with extreme longevity
