Prehistoric sharks rotated their jaws keeping larger, sharper teeth in an upright position, making it "easier for them to impale their prey."

From slot machines to data encryption, many fields need true random numbers. Now researchers have generated them using DNA synthesis for the first time.

Scientists have found a way to make droplets chase each other like predator and prey. It hasn't been done before in a synthetic system.

The Blue Ring Nebula has stumped scientists for years. Now, they may have finally cracked the case: the weird gas blob appears to be from a stellar merger.

A new wireless chip tested in rats could pave the way for advances in our understanding of how the brain works, researchers say.

New research has a tasty explanation for why the combination of oysters and champagne works so well. The work applies to other food pairings, too.

Darwin's theory of evolution should be expanded to include consideration of a DNA stability "energy code"—so-called "molecular Darwinism"—say scientists.

Research with monkeys choosing between juice flavors clarifies how the brain makes decisions by evaluating the benefits of each option.
