Every day our brains are flooded by stimulation — sounds, sights and smells. At the same time, we are constantly engaged in an inner dialogue, ruminating about the past, musing about the future. Somehow the brain filters all this input instantly,…
Scientists have discovered that infants possessing a cell protein called Rhesus (Rh) factor that their mothers lack are twice as likely to develop schizophrenia in young adulthood. Reported in the December issue of the peer-reviewed American Journal of Human Genetics, the study suggests that the gene that codes for Rh factor is to blame for the higher risk. “Previous studies reported a link between mothers and infants who are Rh-incompatible and a higher rate of schizophrenia in the children later in life,” said Dr. Christina Palmer, a research scientist at the UCLA Neuropsychiatric Institute. “Our research is the first to take a genetic approach to examining this increased risk.”
Scientists have coupled the protein that makes fireflies glow with a device similar to a home video camera to eavesdrop on cellular conversations in living mice. The team’s research will allow scientists to study how cellular proteins talk to one another. These communications trigger changes that regulate a healthy body and cause disease when the signals go awry. The findings may speed development of new drugs for cancer, cardiovascular diseases and neurological diseases.
