Explainer: Why scientists sometimes ‘knock out’ genes
How do we learn what a particular molecule does in the body? To find out, scientists often 'knock out' the gene that makes it. Here’s how.

How to view tiny parts of DNA? Make them ‘blink’
A new technique can image nanoscale structures in cells without hurting them. No dyes needed. All you have to do is stimulate them with the right color of light.
