| Posted: 26 Apr 2013 10:50 AM PDT Neuroscientists show how turning down synthesis of a protein improves nerve, muscle function in a common neuropathy. A potential new treatment strategy for patients with Charcot-Marie-Tooth disease is on the horizon. This research may also have relevance for other diseases that result from misfolded proteins, including Alzheimer's disease, Parkinson's, multiple sclerosis, Type 1 diabetes, cancer and mad cow disease. |
| Sea surface temperatures reach highest level in 150 years on Northeast continental shelf Posted: 26 Apr 2013 08:56 AM PDT Sea surface temperatures in the Northeast Shelf Large Marine Ecosystem during 2012 were the highest recorded in 150 years, according to new research. Temperature is also affecting distributions of fish and shellfish on the Northeast Shelf. |
| Posted: 26 Apr 2013 08:56 AM PDT Scientists have long observed that species seem to have become increasingly capable of evolving in response to changes in the environment. But computer science researchers now say that the popular explanation of competition to survive in nature may not actually be necessary for evolvability to increase. |
| Fish win fights on strength of personality Posted: 26 Apr 2013 08:54 AM PDT When predicting the outcome of a fight, the big guy doesn't always win suggests new research on fish. Scientists have found that when fish fight over food, it is personality, rather than size, that determines whether they will be victorious. |
| New excavations in Sweden indicate use of fertilizers 5,000 years ago Posted: 26 Apr 2013 08:48 AM PDT Researchers have spent many years studying the remains of a Stone Age community in Karleby outside the town of Falköping, Sweden. The researchers have for example tried to identify parts of the inhabitants' diet. Right now they are looking for evidence that fertilizers were used already during the Scandinavian Stone Age, and the results of their first analyses may be exactly what they are looking for. |
| Bird navigation: Great balls of iron Posted: 26 Apr 2013 04:38 AM PDT Every year millions of birds make heroic journeys guided by the earth's magnetic field. How they detect magnetic fields has puzzled scientists for decades. Today, biologists have added some important pieces to this puzzle. |
| Posted: 25 Apr 2013 11:23 AM PDT Songbird populations can handle far more disrupting climate change than expected. Density-dependent processes are buying them time for their battle. But without (slow) evolutionary rescue it will not save them in the end, says an international team of scientists. |
| Potential diabetes breakthrough: Hormone spurs beta cell production Posted: 25 Apr 2013 10:26 AM PDT Researchers have discovered a new hormone that holds promise for a dramatically more effective treatment of type 2 diabetes, a metabolic illness afflicting an estimated 26 million Americans. The researchers believe the hormone might also have a role in treating type 1, or juvenile, diabetes. |
