Two researchers from Skoltech and McGill University have published a review of the promising research field known as structural proteomics in the influential journal Chemical Reviews. This field combines protein chemistry and mass spectrometry, an advanced analytical technique for identifying the chemical composition of substances based on precise mass. The […]

The brain has its own housekeeping service, a sophisticated mechanism that cleans up debris that is left over from cellular activity. But scientists have had a hard time figuring out exactly how the brain knows when to initiate this cellular “trash pickup.” A Yale-led team of scientists has identified a […]
