‘Gene drives’ could wipe out whole populations of pests in one fell swoop

Releasing just 100 mice carrying a faulty gene designed to stop them reproducing can remove an entire population of 50,000, a new study shows, paving the way for new eradication efforts.

Can the study of epigenomics lead to personalized cancer treatment?

A field called epigenomics looks at chemical modifications that do not change our DNA sequence but can affect gene activity. What are the limitations, and can biomedicine use this to our advantage?
