Researchers find vast cityscape hidden under deep vegetation linking the Cambodian temples complex

The brain of a dragonfly has to do some serious calculations -- and fast -- if it hopes to nab a mosquito or midge in midair. It has to predict the trajectory of its prey, plot a course to intersect ...    

Millions of years ago, some bats gave up their old habits of hunting for insects and tried something new: drinking blood. These creatures evolved into today’s vampire bats, and it’s mind-boggling to explore all the ways that they evolved to make the most of their sanguine meal.

The genetic code of leprosy-causing bacteria from 1,000-year-old skeletons has been laid bare, showing the bug has hardly changed over the past millennium.
