| Computers can perceive image curves like artists Posted: 23 Nov 2015 07:34 AM PST Imagine computers being able to understand paintings or paint abstract images much like humans. Now a researcher demonstrates a breakthrough concept in the field of computer vision using curves and lines to represent image shapes and furthermore to recognize objects. |
| The complex sneeze, caught on tape Posted: 23 Nov 2015 07:29 AM PST From the daintiest sleeve-stifled 'shoo to the mightiest head-whipping howl, a sneeze is as unique to an individual as a laugh -- we all do it, but everyone seems to do it differently. We know that sneezes can spread infectious diseases like measles, influenza or SARS, suspending viruses in droplets that may be inhaled or deposited onto surfaces and later picked up on the hands of some unsuspecting passerby. But we don't understand exactly how far a sneeze can spread or if and why some people spread sickness through sneezing more effectively than others. |
| Hydra can modify its genetic program Posted: 23 Nov 2015 07:09 AM PST Champion of regeneration, Hydra is capable of reforming a complete individual from any fragment of its body. It is even able to remain alive when all its neurons have disappeared. Researchers have discovered how: cells of the epithelial type modify their genetic program by overexpressing a series of genes, among which some are involved in diverse nervous functions. |
