| Falling lizards use tail for mid-air twist, inspiring lizard-like 'RightingBot' Posted: 01 Jul 2012 04:16 PM PDT Lizards, just like cats, have a knack for turning right side up and landing on their feet when they fall. But how do they do it? Unlike cats, which twist and bend their torsos to turn upright, lizards swing their large tails one way to rotate their body the other, according to new research. A lizard-inspired robot, called "RightingBot," replicates the feat. |
| Printing living tissues: 3-D printed vascular networks made of sugar Posted: 01 Jul 2012 04:16 PM PDT New advances in tissue engineering could one day make a replacement liver from a patient's cells, or animal muscle tissue that could be cut into steaks. One problem with making 3-D tissue structures, however, is keeping the interior cells from suffocating. Now, researchers have developed an innovative solution: they've shown that 3-D printed templates of filament networks can be used to rapidly create vasculature and improve the function of engineered living tissues. |
| Scientists develop alternative to gene therapy Posted: 01 Jul 2012 04:16 PM PDT Scientists have discovered a surprisingly simple and safe method to disrupt specific genes within cells. The scientists highlighted the medical potential of the new technique by demonstrating its use as a safer alternative to an experimental gene therapy against HIV infection. |
| Posted: 01 Jul 2012 04:16 PM PDT Why do some people with similar injuries end up with chronic pain while others recover and are pain free? The first longitudinal brain imaging study to track participants with a new back injury shows that the more two sections of the brain related to emotional and motivational behavior communicate, the greater likelihood a patient will develop chronic pain. Researchers were able to predict, at the beginning of the study, which participants would go on to develop chronic pain based on the level of brain interaction. |
| Rising heat at the beach threatens largest sea turtles, climate change models show Posted: 01 Jul 2012 04:15 PM PDT Climate change could exacerbate existing threats to critically endangered leatherback sea turtles and nearly wipe out the population in the eastern Pacific. Deaths of turtle eggs and hatchlings in nests buried at hotter, drier beaches are the leading projected cause of the potential climate-related decline, according to a new study. |
