The physics involved with stirring a liquid operate the same way as the mathematical functions that secure digital information. This parallel could help in developing even more secure ways of protecting digital information.

Biologists have been puzzled by the evolutionary adaptation behind a common tooth trait of northern Asians and Native Americans: shovel-shaped incisors. An analysis of archeological specimens shows that nearly 100 percent of early Native Americans had shoveled…

In a world first, researchers have identified a new DNA structure -- called the i-motif -- inside cells. A twisted 'knot' of DNA, the i-motif has never before been directly seen inside living cells.

Walls are what they are -- big, dull dividers. With a few applications of conductive paint and some electronics, however, walls can become smart infrastructure that sense human touch, and detect things like gestures and when appliances are used. Researchers fo…

When endangered killer whales swim through the sheltered waters of Puget Sound, they leave behind traces of 'environmental DNA' that researchers can detect as much as two hours later has found.

A machine learning method called 'deep learning,' which has been widely used in face recognition and other image- and speech-recognition applications, has shown promise in helping astronomers analyze images of galaxies and understand how they form and evolve. …

In an advance that makes a more flexible, inexpensive type of solar cell commercially viable, researchers have demonstrated organic solar cells that can achieve 15 percent efficiency.

Global warming will exacerbate soil droughts in Europe - droughts will last longer, affect greater areas, and have an impact on more people. If the earth warms by three degrees Celsius, extreme events could become the normal state in the future.

A close examination of 3.6-million-year-old hominin footprints discovered in Laetoli, Tanzania, suggests our ancestors evolved the hallmark trait of extended leg, human-like bipedalism substantially earlier than previously thought.

A new study of guenon monkeys in Gombe National Park is the first to provide genetic evidence of ongoing mating between two distinct species. These monkeys have successfully been producing hybrid offspring for hundreds maybe even thousands of years. Prior stud…
