When choosing a new leader, people base their decision on desirable characteristics such as honesty and trustworthiness. However once leaders are in power, can we trust them to exercise it in a prosocial manner? 

A new paper in The Leadership Quarterly finds that everyone gradually becomes susceptible to power the longer they have it.  Study author John Antonakis and his colleagues from the University of Lausanne explain, "We looked to examine what Lord Acton said over 100 years ago, that 'Power corrupts and absolute power corrupts absolutely.'"

To investigate this the authors used experimental methods to distinguish between the situational and individual component; and determine if power corrupts or if corrupt individuals are drawn to power.

If you need another good reason to hit the gym, a new study finds it can improve memory. Georgia Institute of Technology researchers have found that an intense workout of as little as 20 minutes can enhance episodic memory, also known as long-term memory for previous events, by about 10 percent in healthy young adults

In video games, and in software downloads and processes, the status bar is often cheered or reviled. But they are here to stay.

And now it may be possible to 'gamify' your medical progress. 

Inspired by a desire to help wounded soldiers, researchers have created a paint-on, see-through, "smart" bandage that glows to indicate a wound's tissue oxygenation concentration - because oxygen plays a critical role in healing. Mapping these levels in severe wounds and burns can help to significantly improve the success of surgeries to restore limbs and physical functions.

Mental illness has been under a lot of criticism in the last few years. The public feels like the psychology field over-medicates people based on subjective symptoms and recent high-profile violent acts all involved people on psychiatric medications.

But there is still recognition that some mental illness is exculpatory and not just bad behavior. That is less so with drug addicts. While addictions are called a disease, and everyone gives lip service to that idea, when it comes to public policy the truth comes out. The public doesn't support insurance, housing, or employment policies that benefit drug addicts, a new Johns Hopkins Bloomberg School of Public Health survey finds.

Americans love their dogs, and most people clean up after their pets when they are out on a walk, but some do not: people who claim they wouldn't pour toxic chemicals or medicines onto the ground because they recognize it gets into waterways delude themselves into believing dog excrement is "natural" and will be okay in waterways.

But it isn't. Bacteria and anti-bacterial strains from dogs can make people sick from dogs just like it does humans, and we recognize that humans should not go to the bathroom on the ground near a lake.

In 1908 the famously plump Venus of Willendorf, thought to be a symbol of fecundity, was discovered during an excavation near the Austrian town of Melk. It has been dated to 30,000 years ago and is one of the world’s earliest examples of figurative art.

Now, a team of archaeologists have dated a number of stone tools excavated recently from the same site to 43,500 years ago. Results show they were part of the Aurignacian culture, which is generally accepted as indicative of modern human presence. It is agreed that modern humans dispersed into Europe, and began to replace Neanderthals, at least 40,000 years ago. The new research pushes this date back to a potentially much earlier time when temperatures north of the Alps were cool.
