| Tiny swimming bio-bots boldly go where no bot has swum before Posted: 17 Jan 2014 04:13 PM PST The alien world of aquatic micro-organisms just got new residents: synthetic self-propelled swimming bio-bots. Engineers have developed a class of tiny bio-hybrid machines that swim like sperm, the first synthetic structures that can traverse the viscous fluids of biological environments on their own.  |
| Chimps can use gestures to communicate in hunt for food Posted: 17 Jan 2014 07:40 AM PST Chimpanzees are capable of using gestures to communicate as they pursue specific goals, such as finding a hidden piece of food, according to a new study.  |
| One step at a time, researchers learning how humans walk Posted: 17 Jan 2014 06:06 AM PST Humans and some of our hominid ancestors such as Homo erectus have been walking for more than a million years, and researchers are close to figuring out how we do it. The research could find some of its earliest applications in improved prosthetic limbs, and later on, a more complete grasp of these principles could lead to walking or running robots that are far more agile and energy-efficient than anything that exists today.  |
| Fighting flies: Brain cells promote fighting in male fruit flies Posted: 17 Jan 2014 06:06 AM PST According to the latest studies from a fly laboratory, male Drosophilae, commonly known as fruit flies, fight more than their female counterparts because they have special cells in their brains that promote fighting. These cells appear to be absent in the brains of female fruit flies.  |
| Renewable chemical ready for biofuels scale-up Posted: 16 Jan 2014 11:46 AM PST Using a plant-derived chemical, researchers have developed a process for creating a concentrated stream of sugars that's ripe with possibility for biofuels.  |
