A tighter fit with artificial DNA

An artificial base that enhances the protein-binding affinity and selectivity of DNA expands the DNA machinery.DNA aptamers are expected to play an important role in the diagnosis and treatment of various cancers and other ...

Chemists discover the structure of a key coronavirus 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 ...
