How Nobel-winning chemists used and directed evolution

Three scientists shared the 2018 Nobel Chemistry Prize on Wednesday for their work in harnessing the power of evolution, which led to a range of breakthroughs including better biofuels and more targeted drugs.

Phages work together to suppress CRISPR bacterial immunity

CRISPR, or clustered regularly interspaced short palindromic repeats, are an essential part of bacterial immunity designed to defend against foreign DNA. In bacteria, CRISPR acts just like it does in human cells as a pair ...
