| Bioinspired robot meets fish: Robotic fish research swims into new ethorobotics waters Posted: 20 Nov 2012 09:20 AM PST New research is illuminating the emerging field of ethorobotics -- the study of bioinspired robots interacting with animal counterparts. They studied how real-time feedback attracted or repelled live zebrafish. The fish were more attracted to robots with tail motions that mimicked the live fish. The researchers hope that robots eventually may steer live animal or marine groups from danger.  |
| Posted: 20 Nov 2012 09:20 AM PST Physicists have shown that synthetic membrane channels can be constructed through "DNA nanotechnology." This technique employs DNA molecules as programmable building materials for custom-designed, self-assembling, nanometer-scale structures. The researchers present evidence that their nature-inspired nanostructures may also behave like biological ion channels. Their results could mark a step toward applications of synthetic membrane channels as molecular sensors, antimicrobial agents, and drivers of novel nanodevices.  |
| Engineered bacteria can make the ultimate sacrifice for the good of the population Posted: 20 Nov 2012 09:19 AM PST Scientists have engineered bacteria that are capable of sacrificing themselves for the good of the bacterial population. These altruistically inclined bacteria can be used to demonstrate the conditions where programmed cell death becomes a distinct advantage for the survival of the bacterial population.  |
| Algae can take energy from other plants Posted: 20 Nov 2012 09:19 AM PST Flowers need water and light to grow. Even children learn that plants use sunlight to gather energy from earth and water. Biologists have made an astounding discovery that one plant has another way of doing this. They have confirmed for the first time that a plant not only engages in photosynthesis, but also has an alternative source of energy: it can draw it from other plants. This finding could also have a major impact on the future of bioenergy.  |
| Urban noise makes flycatchers change length of their songs Posted: 20 Nov 2012 09:19 AM PST Do birds change their tune in response to urban noise? It depends on the bird species, according to new research. Their work shows that while some birds do adapt their songs in noisy conditions by means of frequency changes, others like the vermilion flycatchers adapt their song by means of changes in song lengths.  |
| Sweat glands play major role in healing human wounds Posted: 20 Nov 2012 07:04 AM PST Researchers have discovered one of the body's most powerful secret weapons in healing: sweat glands.  |
| Nanotech device mimics dog's nose to detect explosives Posted: 20 Nov 2012 07:04 AM PST Engineers have designed a detector that uses microfluidic nanotechnology to mimic the biological mechanism behind canine scent receptors. The device is both highly sensitive to trace amounts of certain vapor molecules, and able to tell a specific substance apart from similar molecules.  |
