Fear and anxiety share same bases in brain

A recent report provides new evidence that fear and anxiety reflect overlapping brain circuits. The findings run counter to popular scientific accounts, highlighting the need for a major theoretical reckoning.

Management of a popular game fish, the smallmouth bass

For recreational fishing enthusiasts, the thrill of snagging their next catch comes with discovering what's hooked on the end of the line. In many freshwater streams and rivers -- across the central and eastern parts of the U.S. -- anglers are often catching a popular freshwater game fish: the smallmouth bass.

Cheaters don't always win: Species that work together do better

The sign of a healthy personal relationship is one that is equally mutual - where you get out just as much as you put in. Nature has its own version of a healthy relationship. A team of researchers investigated these interactions, known as mutualisms, and why they are so critical for healthy environments.

Scientists map the human proteome

Twenty years after the release of the human genome, the genetic 'blueprint' of human life, an international research team has now mapped the first draft sequence of the human proteome.

A new approach to artificial intelligence that builds in uncertainty

Artificial intelligence isn't perfect. In fact, it's only as good as the methods and data built into it. Researchers have detailed a new approach to artificial intelligence that builds uncertainty, error, physical laws, expert knowledge and missing data into its calculations and leads ultimately to much more trustworthy models.

Oldest securely dated evidence for a river flowing through the Thar Desert, Western India

Using luminescence dating of ancient river sediments, a new study presents evidence for river activity at Nal Quarry in the central Thar Desert starting from approx. 173 thousand years ago. These findings represent the oldest directly dated phase of river activity in the region and indicate Stone Age populations lived in a distinctly different Thar Desert landscape than we encounter today.
