| 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.  |
| New spin on old method to develop more efficient electronics Posted: 01 Jul 2012 04:16 PM PDT With the advent of semiconductor transistors -- invented in 1947 as a replacement for bulky and inefficient vacuum tubes -- has come the consistent demand for faster, more energy-efficient technologies. To fill this need, researchers are proposing a new spin on an old method: a switch from the use of silicon electronics back to vacuums as a medium for electron transport -- exhibiting a significant paradigm shift in electronics.  |
