Astronomers have detected long wavelength radio emission from a colliding, massive galaxy cluster which, surprisingly, is not detected at the shorter wavelengths typically seen in these objects.

Children living in the vicinity of powerful radio and television transmitters are not significantly more at risk of leukemia than others, according to a new German study.
When reef fish get a mouthful of sand, coral reefs can drown. “We’ve known for a while that having a lot of sediment in the water is bad for corals and can smother them. What we didn’t realize is how permanent this state of affairs can become, to the point where it may prevent the [...]
One of the hallmarks of Alzheimer’s disease is the formation of plaques made of protein aggregates in the brain tissue. There is still considerable debate among scientists as to whether these plaques are the cause of the neuronal death that occurs in Alzheimer’s or just a by-product of the disease, however.
New analytical tools coming on line at the Spallation Neutron Source, the Department of Energy’s state-of-the-art neutron science facility at Oak Ridge National Laboratory, include a beam line dedicated to nuclear physics studies.

Harmless viruses and genetic ‘young cuckoos’ are going to reveal the answers as to how the brain establishes where we are. The understanding of our sense of locality will be the first higher brain function that we understand at a molecular level.

Human’s physical and mental abilities slow as we age, caused by the steady decay of myelin, the “insulation” around neuronal axons.

Herpes simplex virus type I can cause bouts of cold sores, blindness and potentially lethal encephalitis when it reawakens from a quiescent state in the nerve cells it infects. To prevent these consequences, the stealthy virus is kept under constant guard by the immune system, say University of Pittsburgh scientists. Their research challenges the once [...]
Once a toddler has mastered the art of walking, it seems to come naturally for the rest of her life. But walking and running require a high degree of coordination between the left and right sides of the body. Now researchers have shown how a class of spinal cord neurons, known as V3 neurons, makes [...]
Research results show that the progression of age-related macular degeneration is markedly slowed in new laboratory-engineered mice when they received treatments of retinylamine, a trial drug that has been tested in a medical school lab. AMD is a leading cause of vision loss in Americans 60 years of age and older.
