Genghis Khan’s genetic legacy has competition
Millions of men bear the genetic legacy of Genghis Khan, the famously fertile Mongolian ruler who died in 1227. Researchers have now recognized ten other men whose fecundity has left a lasting impression on present-day populations. The team’s study points to sociopolitical factors that foster such lineages, but the identities of the men who left their genetic stamp remains unknown.
GM microbes created that can’t escape the lab
Critics of genetic engineering have long worried about the risk of modified organisms escaping into the environment. A biological-containment strategy described this week in Nature has the potential to put some of those fears to rest and to pave the way for greater use of engineered organisms in areas such as agriculture, medicine and environmental clean-up.
Hidden hurdle for women in science
Women shy away from fields in which talent, not hard work, is thought to be key, survey suggests.
Blown-up brains reveal nanoscale details
Microscopes make living cells and tissues appear bigger. But what if we could actually make the things bigger?
Game theorists crack poker
An ‘essentially unbeatable’ algorithm for the popular card game points to strategies for solving real-life problems without having complete information.
Rave drug holds promise for treating depression fast
Companies and clinicians turn to ketamine to treat mental-health disorder as pipeline of new drugs dries up.
An ant, a plant, and a bear, oh my
In a mountain meadow in Colorado, ecologists have come across yet another example of the amazing interconnectedness of nature’s flora and fauna. Black bears, by eating ants, help one of the meadow’s key plant species thrive.
