The gates of serotonin
Serotonin is a major neurotransmitter, regulating mood, appetite, sleep, memory, learning, and other functions by binding to dedicated receptor proteins. Serotonin receptors have been researched for decades, but details about their structure and function are hard to come by. EPFL scientists have now made the first ever computer simulation of a notoriously elusive serotonin receptor that is involved in fast signal transmission in neurons and plays a central role in disorders such as schizophrenia, chemotherapy nausea, irritable bowel syndrome, anxiety, and seizures. The work is published in the journal Structure._EPFL
Amazing spider silk
Biophysicists at Johns Hopkins University have discovered one of the keys to the super-elasticity of spiders’ webs, finding that proteins in the silk used to make the webs act like supersprings and can stretch to five times their initial length.__HUB
