| Kestrel inspires unpowered, autonomous glider to climb higher Posted: 18 Dec 2015 05:59 AM PST Researchers have drawn inspiration from the way kestrels hover above their prey to develop an autonomous fixed-wing micro air vehicle (MAV) that can gain height from convenient updrafts. |
| Posted: 18 Dec 2015 05:54 AM PST Researchers have found a way to--literally--multiply teeth. In mice, they were able to extract teeth germs--groups of cells formed early in life that later develop into teeth, split them into two, and then implant the teeth into the mice's jaws, where they developed into two fully functional teeth. |
| Burgess Shale fossil site gives up oldest evidence of brood care Posted: 17 Dec 2015 10:03 AM PST Researchers have discovered the oldest direct evidence of brood care, with the identification of eggs containing preserved embryos in fossils of the 508-million-year-old Waptia fieldensis. Recent analysis of specimens of the shrimp-like creature found in the renowned Canadian Burgess Shale fossil deposit more than a century ago, revealed clusters of egg-shaped objects located on the underside of a bivalved carapace alongside the anterior third of the body. |
| Posted: 16 Dec 2015 05:25 AM PST Bells are a popular source of festive delight during the Christmas period – and now beautiful images showing in unprecedented detail how bells vibrate to make a harmonious sound have been produced by a group of investigators. |
| The double life of a bacteria: Living off both iron and pure electricity Posted: 16 Dec 2015 05:23 AM PST The bacterium Acidithiobacillus ferrooxidans can take electrons needed for growth directly from an electrode power source when iron—its already known source of energy—is absent, new research shows. The study shows that A. ferrooxidans can use direct uptake of electrons from an electrode to fuel the same metabolic pathway that is activated by the oxidation of diffusible iron ions. |
| How researchers are turning 'Star Wars' droids into reality Posted: 15 Dec 2015 09:28 AM PST The enduring popularity of and interest in droids like C-3PO and R2-D2 speaks to the fascination many people have with robotics and artificial intelligence. Although no one will have their own C-3PO soon, a number of researchers are working to make droids more science fact than science fiction. |
