Dogs pick out faces of other dogs, irrespective of breeds, among human and other domestic and wild animal faces and can group them into a category of their own. They do that using visual cues alone, according to new research by Dr. Dominique Autier-Dérian from the LEEC and National Veterinary School in Lyon in France and colleagues.
New data from NASA's Chandra X-ray Observatory suggest a highly distorted supernova remnant may contain the most recent black hole formed in the Milky Way galaxy. The remnant appears to be the product of a rare explosion in which matter is ejected at high speeds along the poles of a rotating star.
A genome-wide analysis searching for evidence of long-lived balancing selection -- where the evolutionary process acts not to select the single best adaptation but to maintain genetic variation in a population -- has uncovered at least six regions of the genome where humans and chimpanzees share the same combination of genetic variants.
The first animal model of recent human evolution reveals that a single mutation produced several traits common in East Asian peoples, from thicker hair to denser sweat glands, an international team of researchers reports.
Researchers at The University of Arizona Cancer Center at St. Joseph's Hospital and Medical Center in Phoenix have discovered that many women with low-grade serous carcinoma of the ovary or peritoneum have seen their tumors stabilize or shrink after taking a regular dose of the compound selumetinib.
A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward understanding the origin of cosmic rays, one of Fermi's primary mission goals.
Increasingly frequent extreme weather events such as droughts, floods, severe storms, and heat waves have focused the attention of climate scientists on the connections between greenhouse warming and extreme weather. Because of the potential threat to U.S.
Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It's because granular materials -- like sand or dirt -- can change their behavior, or state. Researchers from North Carolina State University have found that the forces individual grains exert on one another are what most affect that transition.
Organic semiconductors hold promise for making low-cost flexible electronics -- conceivably video displays that bend like book pages or roll and unroll like posters, or wearable circuitry sewn into uniforms or athletic wear.
A team of researchers at the University of Waterloo's Institute for Quantum Computing has proposed a new computational model that may become the architecture for a scalable quantum computer.
