| Novel approach to view inner workings of viruses Posted: 12 Jan 2012 12:16 PM PST Researchers have developed a new way to see structures within viruses that were not clearly seen before. |
| Breakthrough model reveals evolution of ancient nervous systems through seashell colors Posted: 12 Jan 2012 11:23 AM PST Determining the evolution of pigmentation patterns on mollusk seashells -- which could aid in the understanding of ancient nervous systems -- has proved to be a challenging feat for researchers. Now, however, through mathematical equations and simulations, researchers have used 19 different species of the predatory sea snail Conus to generate a model of the pigmentation patterns of mollusk shells. |
| Wandering albatross alters its foraging due to climate change Posted: 12 Jan 2012 11:22 AM PST Wandering albatrosses have altered their foraging due to changes in wind fields in the southern hemisphere during the last decades. Since winds have increased in intensity and moved to the south, the flight speed of albatrosses increased and they spend less time foraging. As a consequence, breeding success has improved and birds have gained 1 kilogram. |
| Offsetting global warming: Molecule in Earth's atmosphere could 'cool the planet' Posted: 12 Jan 2012 11:22 AM PST Scientists have shown that a newly discovered molecule in Earth's atmosphere has the potential to play a significant role in offsetting global warming by cooling the planet. |
| New insights into an ancient mechanism of mammalian evolution Posted: 12 Jan 2012 10:43 AM PST A team of geneticists and computational biologists have reveal how an ancient mechanism is involved in gene control and continues to drive genome evolution. |
| Honeybee deaths linked to seed insecticide exposure Posted: 12 Jan 2012 08:27 AM PST Honeybee populations have been in serious decline for years, and scientists may have identified one of the factors that cause bee deaths around agricultural fields. |
| Explosives and fish are traced with chemical tags Posted: 12 Jan 2012 08:26 AM PST Researchers have come up with a way of tagging gunpowder which allows its illegal use to be detected even after it has been detonated. Based on the addition of isotopes, the technique can also be used to track and differentiate between wild fish and those from a fish farm, such as trout and salmon. |
| Worm seeks worm: Chemical cues drive aggregation in nematodes Posted: 12 Jan 2012 07:06 AM PST Scientists have long seen evidence of social behavior among many species of animals. Dolphins frolic together and lions live in packs. And, right under our feet, it appears that nematodes are having their own little gatherings in the soil. Until recently, it was unknown how the worms communicate to one another when it's time to come together. Now, researchers have identified, for the first time, the chemical signals that promote aggregation. |
