| Waterfall-climbing fish use same mechanism to climb waterfalls and eat algae Posted: 04 Jan 2013 05:38 PM PST Going against the flow is always a challenge, but some waterfall-climbing fish have adapted to their extreme lifestyle by using the same set of muscles for both climbing and eating, according to new research. |
| New way to study permafrost soil, above and below ground Posted: 04 Jan 2013 12:50 PM PST Scientists have developed a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world's soils and about twice as much as is in the atmosphere. The new approach combines several remote-sensing tools to study the Arctic landscape, above and below ground, in high resolution and over large spatial scales. |
| Drainage ditches can help clean up field runoff Posted: 04 Jan 2013 11:36 AM PST Vegetated drainage ditches can help capture pesticide and nutrient loads in field runoff, scientists report. These ditches -- as common in the country as the fields they drain -- give farmers a low-cost alternative for managing agricultural pollutants and protecting natural resources. |
| Waste removal in worms reveals new mechanism to regulate calcium signaling Posted: 04 Jan 2013 11:36 AM PST Calcium is so much more than the mineral that makes our bones and teeth strong: It's a ubiquitous signaling molecule that provides crucial information inside of and between cells. Scientists have discovered a new way that calcium signaling may be controlled. In worms, a specific microRNA fine tunes such signaling, a finding that should be of great help to the thousands of scientists who study the important role of calcium signaling in health and disease. |
| Under the weather, literally: More rainfall and bigger storms may lead to more stomach upsets Posted: 04 Jan 2013 11:35 AM PST We can blame all sorts of things on the weather. But a stomach bug? It seems unlikely. Yet, scientists say greater quantities of rainfall and bigger storms will lead to more stomach upsets in parts of Europe. |
| Pesticides and Parkinson's: Further proof of a link uncovered Posted: 04 Jan 2013 07:14 AM PST Researchers have found a link between Parkinson's disease and the pesticide Benomyl, whose toxicological effects still linger in the environment, 10 years after it was banned by the EPA. More important, the research suggests the way this pesticide does its damage may occur in other people with Parkinson's, even for those who were not exposed to this pesticide. |
| Photosynthesis: The last link in the chain Posted: 04 Jan 2013 07:11 AM PST For almost 30 years, researchers have sought to identify a particular enzyme that is involved in regulating electron transport during photosynthesis. Biologists have now found the missing link, which turns out to be an old acquaintance. |
| Dinosaur shook tail feathers for mating show Posted: 04 Jan 2013 05:31 AM PST A researcher's examination of fossilized dinosaur tail bones has led to a breakthrough finding: some feathered dinosaurs used tail plumage to attract mates, much like modern-day peacocks and turkeys. |
| Structural studies of a toxin from Bacillus cereus that causes diarrhea Posted: 04 Jan 2013 05:31 AM PST Food poisoning caused by Bacillus cereus can lead to diarrhea which is probably caused by a 3-component toxin which is produced by this bacteria strain and which perforates and kills cells. New research has revealed one of the protein structures of this toxin and has led to a better understanding of the mechanisms behind multi-component, pore-forming toxins. These findings can enhance food safety. |
