A molecular on/off switch for CRISPR

Picture bacteria and viruses locked in an arms race. For many bacteria, one line of defense against viral infection is a sophisticated RNA-guided "immune system" called CRISPR-Cas. At the center of this system is a surveillance ...

Compact CRISPR systems found in some of world's smallest microbes

UC Berkeley scientists have discovered simple CRISPR systems similar to CRISPR-Cas9—a gene-editing tool that has revolutionized biology—in previously unexplored bacteria that have eluded efforts to grow them in the laboratory.

Hijacked cell division helped fuel rise of fungi

A new study finds that the more than 90,000 species of mushrooms, molds, yeasts and other fungi found everywhere in the soil, water and air may owe their abilities to grow, spread, and even cause disease to an opportunistic ...
