| Benefit vs. risk of facial recognition technology Posted: 08 May 2013 06:32 PM PDT Law enforcement agencies are using facial recognition software as a crime-fighting tool. Now businesses are looking to use the technology to reach customers. But a professor questions whether customers are ready for it. |
| Cannibal tadpoles key to understanding digestive evolution Posted: 08 May 2013 10:18 AM PDT A carnivorous, cannibalistic tadpole may play a role in understanding the evolution and development of digestive organs, according to new research. |
| Posted: 08 May 2013 10:18 AM PDT Like pioneers in search of a better life, bacteria on a surface wander around and often organize into highly resilient communities, known as biofilms. It turns out that a lucky few bacteria become the elite cells that start the colonies, and they organize in a rich-get-richer pattern similar to the distribution of wealth in the US economy, according to a new study. |
| Using 'bacteria-eaters' to prevent infections on medical implant materials Posted: 08 May 2013 09:30 AM PDT Viruses that infect and kill bacteria -- used to treat infections in the pre-antibiotic era a century ago and in the former Soviet Union today -- may have a new role in preventing formation of the sticky "biofilms" of bacteria responsible for infections on implanted medical devices. |
| First biological evidence of a supernova Posted: 08 May 2013 09:30 AM PDT In fossil remnants of bacteria, researchers have found a radioactive iron isotope that they trace back to a supernova in our cosmic neighborhood. This is the first proven biological signature of a starburst. An age determination showed that the supernova must have occurred about 2.2 million years ago, roughly around the time when the modern human developed. |
| Differences between 'marathon mice' and 'couch potato mice' reveal key to muscle fitness Posted: 08 May 2013 07:26 AM PDT Using "marathon" and "couch potato" mouse models, researchers have discovered that microRNAs link the defining characteristics of fit muscles: The abilities to burn fuel and switch between muscle fiber types. They also found that active people have higher levels of one microRNA than sedentary people. |
| 'Invisibility cloak' for thermal flow constructed Posted: 08 May 2013 06:29 AM PDT By means of special metamaterials, light and sound can be passed around objects. Researchers have now succeeded in demonstrating that the same materials can also be used to specifically influence the propagation of heat. A structured plate of copper and silicon conducts heat around a central area without the edge being affected. |
| World's most extreme hearing animal: The greater wax moth Posted: 08 May 2013 06:28 AM PDT Researchers have discovered that the greater wax moth is capable of sensing sound frequencies of up to 300 kHz -- the highest recorded frequency sensitivity of any animal in the natural world. |
| An electronic nose can tell pears and apples apart Posted: 08 May 2013 06:28 AM PDT Engineers have created a system of sensors that detects fruit odors more effectively than the human sense of smell. For now, the device can distinguish between the odors compounds emitted by pears and apples. Scientists have created an electronic nose with 32 sensors that can identify the odors given off by chopped pears and apples. |
