While cancer cells have been known to compete with each other for resources, it seems that they have also found a way to work together to gather nutrients. When exposed to amino acids, cells can ...

Researchers are building out the repertoire of chemical reactions, using light. They report a method using photobiocatalysis to produce non-canonical (not naturally occurring) amino acids that are ...
