Running may have made dinosaurs' wings flap before they evolved to fly: New evidence suggests that passive wing flapping may have arisen earlier than gliding flight

The findings, published in PLOS Computational Biology, provide new insights into the origin of avian flight, which has been a point of debate since the 1861 discovery of Archaeopteryx.

New 3-foot-tall relative of Tyrannosaurus rex

The newly named tyrannosauroid dinosaur -- Suskityrannus hazelae -- stood roughly 3 feet tall at the hip and was about 9 feet in length, the entire animal only marginally longer than the just the skull of a fully grown Tyrannosaurus rex, according to Sterling Nesbitt, an assistant professor with Department

Experimental device generates electricity from the coldness of the universe

An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe..

Knit 1, purl 2: Assembly instructions for a robot? Researchers make soft, actuated objects using commercial knitting machines

Software developed by researchers from CMU's Morphing Matter Lab and Dev Lab in the Human-Computer Interaction Institute makes it possible for the objects to emerge from the knitting machines in their desired shapes and with tendons already embedded. They can then be stuffed and the tendons attached to motors, as

Water found in samples from asteroid Itokawa: Up to half of Earth's ocean water may have come from impacts by asteroids

The team's findings suggest that impacts early in Earth's history by similar asteroids could have delivered as much as half of our planet's ocean water.

New 'jumping' superbug gene discovered, resistant to last-resort antibiotic

Doctors deploy the antibiotic colistin when all other infection-fighting options are exhausted.But resistance to colistin has emerged around the globe, threatening its efficacy.

Hubble astronomers assemble wide view of the evolving universe

The deep-sky mosaic, created from nearly 7,500 individual exposures, provides a wide portrait of the distant universe, containing 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the big bang. The faintest and farthest galaxies are just one ten-billionth

Researchers crack the peanut genome: New genome map sheds light on ancestry, diversity of today's peanuts

Researchers working as part of the International Peanut Genome Initiative have previously pinpointed one of the peanut's two wild ancestors and shown that the peanut is a living legacy of some of the earliest human agricultural societies in South America. Since then the team has mapped the entire peanut genome

Fracking: Earthquakes are triggered well beyond fluid injection zones: Computer model and field experiment data suggest a new link between subsurface injections and earthquake swarms

The results account for the observation that the frequency of human-made earthquakes in some regions of the country surpass natural earthquake hotspots..

Arsenic-breathing life discovered in the tropical Pacific Ocean

"Thinking of arsenic as not just a bad guy, but also as beneficial, has reshaped the way that I view the element," said first author Jaclyn Saunders, who did the research for her doctoral thesis at the UW and is now a postdoctoral fellow at the Woods Hole Oceanographic Institution
