| Gecko feet inspire amazing glue that can hold 700 pounds on smooth wall Posted: 16 Feb 2012 01:55 PM PST Biologists have long been amazed by gecko feet, which allow 5-ounce lizards to produce an adhesive force equivalent to carrying 9 lbs. up a wall without slipping. Now, a team of polymer scientists and a biologist have invented "Geckskin," an adhesive device that can hold 700 pounds on a smooth wall. |
| Researchers make living model of brain tumor Posted: 16 Feb 2012 10:43 AM PST Researchers have created a living 3-D model of a brain tumor and its surrounding blood vessels. In experiments, the scientists report that iron-oxide nanoparticles carrying the agent tumstatin were taken by blood vessels, meaning they should block blood vessel growth. The living-tissue model could be used to test the effectiveness of nanoparticles in fighting other diseases. |
| Posted: 16 Feb 2012 10:34 AM PST Researchers have sequenced the genome of a contagious cancer that is threatening the Tasmanian devil, the world's largest carnivorous marsupial, with extinction. Cataloguing the mutations present in the cancer has led to clues about where the cancer came from and how it became contagious. |
| Why do dinosaur skeletons look so weird? Posted: 16 Feb 2012 08:12 AM PST Many fossilized dinosaurs have been found in a twisted posture. Scientists have long interpreted this as a sign of death spasms. Researchers have now come to the conclusion that these bizarre deformations occurred only during decomposition of dead dinosaurs. |
| Video games lead to new paths to treat cancer, other diseases Posted: 16 Feb 2012 06:46 AM PST The cure for cancer comes down to this: video games. Scientists have made highly realistic video game images that simulate the inner workings of human cells. Playing these 'games' helps medical researchers see exactly how cells live, divide and die. The research opens new paths for tumor-killing drugs to treat cancer and other diseases. |
