Gene breakthrough brings glaucoma drugs a step closer

Scientists have discovered that the high pressure in the eye that occurs with most common forms of glaucoma can trigger two genes that work together to cause vision loss, which may help pave the way for new glaucoma drugs.

Differences between men and women are more than the sum of their genes

What produces the differences between men and women? Are they trivial or profound? Are they genetic or environmental, or both? And are men really closer genetically to chimpanzees than to women?

Kinky genes: how we fit three metres of DNA into a cell nucleus

When scientists first decided to sequence the human genome, it seemed an impossibly large and complicated challenge. A decade since achieving this aim, scientists are faced with a similarly overwhelming…
