Surgeons have demonstrated that artificial muscles can restore the ability of patients with facial paralysis to blink, a development that could benefit the thousands of people each year who no longer are able to close their eyelids due to combat-related injuries, stroke, nerve injury or facial surgery.

Loss of epigenetic regulators causes mental retardation
01.18.2010 16:00 2 views 0 comments Tags: Love
Developing neurons don't just need the right genes to guide them as they grow, they need access to the right genes at the right times. The improper functioning of one specific protein complex that normally suppresses gene activation is responsible for a mental retardation-like syndrome in mice. Read more »

Genetic analysis disputes increase in Antarctic minke whales
01.18.2010 16:00 1 views 0 comments
A new genetic analysis of Antarctic minke whales concludes that population of these smaller baleen whales have not increased as a result of the intensive hunting of other larger whales -- countering arguments by advocates of commercial whaling who want to "cull" minke whales. Read more »

Why mice develop 'knots' while exploring a new environment
01.18.2010 16:00 2 views 0 comments
During exploration of a new environment, mice establish "knots" -- preferred places visited sporadically and marked by the performance of twists and turns, according to a new study. The research provides evidence that the formation of these places is increased by stress, and suggests that the tortuous movements improve the interpretation of the visual scene, enhance the memory of the place and provide the mouse with multiple views that turn the established places into navigational landmarks.

Walking robot switches gaits autonomously and flexibly
01.18.2010 10:00 3 views 0 comments Tags: Ever
Even simple insects can generate quite different movement patterns with their six legs. The animal uses various gaits depending on whether it crawls uphill or downhill, slowly or fast. Scientists have now developed a walking robot, which can flexibly and autonomously switch between different gaits. The success of their solution lies in its simplicity: a small and simple network with just a few connections can create very diverse movement patterns. To this end, the robot uses a mechanism for "chaos control." Read more »

Making microscopic worms into a more deadly insecticide
01.18.2010 10:00 2 views 0 comments Tags: There
Microscopic nematode worms can be a potent organic insecticide, killing crop-raiding bugs without without environmental side effects of chemicals. But when the worms are mass-bred for agriculture, they tend to "wimp out," and are not as deadly as their cousins that grow in the wild. A new study identified the genetic changes in lab-raised worms that make them less deadly to insects. These insights also provide a map for weakening worms that target humans. Read more »

Punishment important in plant-pollinator relationship
01.18.2010 7:00 2 views 0 comments Tags: Five
Figs and the wasps that pollinate them present one of biologists' favorite examples of a beneficial relationship between two different species. In exchange for the pollination service provided by the wasp, the fig fruit provides room and board for the wasp's developing young. However, wasps do not always pollinate the fig. Fig trees "punish" these "cheaters" by dropping unpollinated fruit, killing the wasp's offspring inside, report researchers. Read more »

Scientists have found 13 new genetic variants that influence blood glucose regulation, insulin resistance, and the function of insulin-secreting beta cells in populations of European descent. Five of the newly discovered variants increase the risk of developing type 2 diabetes, the most common form of diabetes. Read more »
