| How protein in teardrops annihilates harmful bacteria: Novel technology reveals lysozymes have jaws Posted: 19 Jan 2012 11:33 AM PST A disease-fighting protein in our teardrops has been tethered to a tiny transistor, enabling scientists to discover exactly how it destroys dangerous bacteria. The research could prove critical to long-term work aimed at diagnosing cancers and other illnesses in their very early stages. |
| Toward twister forecasting: Scientists make progress in assessing tornado seasons Posted: 19 Jan 2012 10:40 AM PST A new study of short-term climate trends offers the first framework for predicting tornado activity up to a month out with current technology, and possibly further out as climate models improve, giving communities a chance to plan. The study may also eventually open a window on the question of whether tornadoes are growing more frequent due to long-term climate warming. |
| Posted: 19 Jan 2012 07:15 AM PST Astronomers have captured a striking new image of the Helix Nebula. A new picture, taken in infrared light, reveals strands of cold nebular gas that are invisible in images taken in visible light, as well as bringing to light a rich background of stars and galaxies. The Helix Nebula is one of the closest and most remarkable examples of a planetary nebula. |
| Unusual 'tulip' creature discovered: Lived in the ocean more than 500 million years ago Posted: 18 Jan 2012 02:36 PM PST A bizarre creature that lived in the ocean more than 500 million years ago has emerged from the famous Middle Cambrian Burgess Shale in the Canadian Rockies. Officially named Siphusauctum gregarium, fossils reveal a tulip-shaped creature that is about the length of a dinner knife (approximately 20 centimeters or eight inches) and has a unique filter feeding system. |
| Umbilical cord stem cells converted into brain support cells Posted: 17 Jan 2012 11:43 AM PST Researchers have succeeded in converting stem cells from umbilical cords into other types of cells, which may eventually lead to new treatment options for spinal cord injuries and multiple sclerosis, among other nervous system diseases. |
| 'Bubblegram' imaging: Novel approach to view inner workings of viruses Posted: 12 Jan 2012 12:16 PM PST Since the discovery of the microscope, scientists have tried to visualize smaller and smaller structures to provide insights into the inner workings of human cells, bacteria and viruses. Now, researchers have developed a new way to see structures within viruses that were not clearly seen before. |
| Almost perfect: Researcher nears creation of superlens Posted: 09 Jan 2012 07:29 AM PST A superlens would let you see a virus in a drop of blood and open the door to better and cheaper electronics. It might, says one researcher, make ultra-high-resolution microscopes as commonplace as cameras in our cell phones. |
