Mammals Can Be Stimulated To Regrow Damaged Inner Retina Nerve Cells - For the first time the mammalian retina has now shown the capacity to regenerate new neurons after damage. This research in mice shows that at least some types of retinal damage can be repaired. The loss of neurons in the retina in people in conditions like glaucoma or macular degeneration leads to visual loss and blindness. This new research shows there might someday be a way to restore vision in people with these conditions.... How Brain Cells Can Survive A Stroke: Workings Of Emergency Brake In Brain - Brain researchers have penetrated deeply into the innermost secrets of the brain to find out how brain cells can survive a stroke. Strokes are usually caused by occlusion of one of the blood vessels in the brain. When blood is prevented from supplying vital oxygen and energy to the brain cells, their electrochemical balance is upset, and they cause damage to themselves and to the surrounding brain cells before they collapse and die. Often this affects the memory center, the hippocampus, where the cells are particularly vulnerable....

Drop In Cancer Deaths Tied Primarily To Gains In Behavior And Screening - Behavior change and improvements in screening have contributed equally and substantially to the 13 percent decline in cancer mortality rates, according to new research. Cancer treatment after diagnosis has also contributed to the decline, although this is less of a factor than behavioral changes and screening.... Why We Remember Important Things And Forget Trivia: Neuron's Synapses Remodel Themselves - Where would we be without our ability to remember important information or, for that matter, to forget irrelevant details? Thanks to the flexibility of the nerve cell's communication units, called synapses, we are good at both. Up to now, only the receiving side of a synapse was believed to play an active role in this reorganization of the brain, which is thought to underlie our ability to learn but also to forget. An incorrect assumption, as scientists can now show.... Vaccine Against Multiple Sclerosis?
