Scientists say they have taken a big step toward developing a new generation of drugs that treat diseases by turning genes on and off.


Word of the Day
ecotone
  • A transitional zone between two communities containing the characteristic species of each.
The word 'ecotone' comes 'eco-' plus a Greek root meaning 'tension'.
