| New clues about hereditary spastic paraplegia Posted: 08 Jul 2011 09:45 AM PDT New research is yielding clues about hereditary spastic paraplegia (HSP), a group of inherited neurological disorders that affect about 20,000 people in the United States. A new study offers the first detailed account of the biochemical workings of atlastin, a protein produced by one of the genes linked to HSP.  |
| Viruses bathe in rivers and at the beach, too, European study finds Posted: 08 Jul 2011 05:26 AM PDT European researchers have found viruses in nearly 40% of more than 1,400 bathing water samples gathered from coastal and inland areas in nine countries, including Spain. The concentrations found are low, but the scientists are calling for these microorganisms to be monitored in recreational waters, above all at times when their populations skyrocket, as is the case after heavy rains.  |
| Sex -- as we know it -- works thanks to ever-evolving host-parasite relationships, biologists find Posted: 07 Jul 2011 11:11 AM PDT Biologists have found that, although sexual reproduction between two individuals is costly from an evolutionary perspective, it is favored over self-fertilization in the presence of coevolving parasites. Sex allows parents to produce offspring that are more resistant to the parasites, while self-fertilization dooms populations to extinction at the hands of their biological enemies.  |
