Linchpin of skin response to UVA light discovered

Linchpin of skin response to UVA light discovered

Jan. 21, 2013 — Researchers have strengthened their understanding of how skin cells called melanocytes sense ultraviolet light and act to protect themselves with melanin. In a new study, they report experiments showing that an ion channel well-known elsewhere in the body for its chemical sensitivity, plays a central role in this process Continue reading

One form of neuron turned into another in brain

One form of neuron turned into another in brain

Jan. 20, 2013 — A new finding by Harvard stem cell biologists turns one of the basics of neurobiology on its head — demonstrating that it is possible to turn one type of already differentiated neuron into another within the brain Continue reading

Light exposure during pregnancy key to normal eye development

Light exposure during pregnancy key to normal eye development

Jan. 16, 2013 — New research in Nature concludes the eye — which depends on light to see — also needs light to develop normally during pregnancy. Scientists say the unexpected finding offers a new basic understanding of fetal eye development and ocular diseases caused by vascular disorders — in particular one called retinopathy of prematurity that can blind premature infants.

Choline supplementation during pregnancy presents a new approach to schizophrenia prevention

Choline supplementation during pregnancy presents a new approach to schizophrenia prevention

Jan. 15, 2013 — Choline, an essential nutrient similar to the B vitamin and found in foods such as liver, muscle meats, fish, nuts and eggs, when given as a dietary supplement in the last two trimesters of pregnancy and in early infancy, is showing a lower rate of physiological schizophrenic risk factors in infants 33 days old Continue reading

New target for common heart condition identified

Jan. 8, 2013 — Researchers have found new evidence that metabolic stress can increase the onset of atrial arrhythmias, such as atrial fibrillation (AF), a common heart condition that causes an irregular and often abnormally fast heart rate. Continue reading
