A protein that turns on the production of reactive chemicals in mouse immune cells is essential to fight Klebsiella pneumonia bacteria, a common cause of infections in hospitals.

The Sox8 gene is capable of triggering female mice to develop male physical characteristics.

A more natural form of DNA, where it is wrapped around proteins, is a more efficient template for adding new sequences to the genome in gene-editing experiments.

The ‘guardian of the genome’ p53 may protect cells against damage but it also limits the efficiency of CRISPR-Cas9 genome editing.

Fruit flies release eggs from their ovaries using a similar gene to mammals.

A protein complex in fruit flies comes in two flavors that each regulate gene activity in different ways.

Mutant zebrafish that almost completely lack macrophages provide a unique opportunity to better understand these cells.

A brain region called the hippocampus helps humans use previous experiences to decide where to focus our attention next.
