Tau protein in Alzheimer's disease looks different at every dementia stage

Research into Alzheimer's disease has long focused on understanding the role of two key proteins, beta amyloid and the tau protein. Found in tangles in patients' brain tissue, a pathological form of the tau protein contributes to propagating the disease in the brain.

MIT chemists determine molecular structure of SARS-CoV-2 protein

MIT chemists have determined the molecular structure of a protein found in the SARS-CoV-2 virus. This protein, called the envelope protein E, forms a cation-selective channel and plays a key role in the virus's ability to replicate itself and stimulate the host cell's inflammation response.
