| Crayfish species proves to be the ultimate survivor Posted: 03 Aug 2012 04:38 PM PDT Red swamp crayfish, known as one of the most successful invaders on earth, is able to feed off the land as well as getting food from its usual source in the water. |
| Ancient records shed light on Italian earthquakes (Aquila area) Posted: 03 Aug 2012 10:19 AM PDT When a damaging earthquake struck the area of L'Aquila in central Italy in 2009, it was the latest in the region's long history of strong and persistent quakes. But according to a new study the historical record on ancient and medieval earthquakes comes with its own shortcomings that must be addressed before the seismic history of L'Aquila can be useful in assessing the current seismic hazard in this area. |
| Birds that live with varying weather sing more versatile songs Posted: 03 Aug 2012 10:19 AM PDT A new study of North American songbirds reveals that birds that live with fluctuating weather are more flexible singers. Mixing it up helps birds ensure that their songs are heard no matter what the habitat. |
| Situation dire for threatened rhino species, researcher finds Posted: 03 Aug 2012 09:11 AM PDT A researcher hopes his recent finding confirming the extinction of the Javan rhinoceros in Vietnam pushes the public to protect the last remaining group of these prehistoric creatures living in Indonesia. |
| Giant moa had climate change figured out Posted: 03 Aug 2012 08:44 AM PDT An international team of scientists has used ancient DNA from bones of giant extinct New Zealand birds to show that significant climate and environmental changes did not have a large impact on their populations. |
| Researchers invent new tool to study single biological molecules Posted: 03 Aug 2012 08:08 AM PDT Researchers have developed new microscope technology to study single biological molecules with unprecedented accuracy and precision. |
| Predatory beetles eavesdrop on ants' chemical conversations to find best egg-laying sites Posted: 03 Aug 2012 07:29 AM PDT Predatory beetles can detect the unique alarm signal released by ants that are under attack by parasitic flies, and the beetles use those overheard conversations to guide their search for safe egg-laying sites on coffee bushes. |
| Bears, scavengers count on all-you-can-eat salmon buffet lasting for months Posted: 03 Aug 2012 06:44 AM PDT Watersheds need both steep, cold-running streams and meandering streams of warmer water to keep options open for salmon. Preserving that sort of varied landscape serves not just salmon, it provides an all-summer buffet that animals need to sustain themselves the rest of the year. |
| Posted: 03 Aug 2012 05:29 AM PDT Soil is the most species-rich microbial ecosystem in the world. From this incredible diversity, plants specifically choose certain species, give them access to the root and so host a unique, carefully selected bacterial community from which they then benefit in a variety of ways. To achieve this, the plant's immune system must be able to tell which of these bacteria are friends and which foes. |
| Novel double-stranded DNA structure produced through mechanical stretching Posted: 03 Aug 2012 05:29 AM PDT Researchers' findings address a scientific debate that had lasted for 16 years over the existence of a double-stranded DNA structure. |
| Posted: 03 Aug 2012 05:29 AM PDT Scientists have combined the power of two kinds of microscope to produce a 3-dimensional movie of how cells 'swallow' nutrients and other molecules by engulfing them. The study is the first to follow changes in the shape of the cell's membrane and track proteins thought to influence those changes. It also provides ample data to investigate this essential process further. |
