Parasite offers natural way to control leaf-eating slugs

Researchers at Ohio State University have discovered a natural parasite that can control leaf-eating slugs, which destroy crops every spring and fall. The parasite, known as Phasmarhabditis hermaphrodita, is effective in killing American slugs just as well as the most popular slug poison, metaldehyde.

Genomes on 'chips' boon to cancer research

Researchers used DNA-coated microchips to discover that flavopiridol works by broadly inhibiting messenger RNA molecules, which are responsible for carrying genetic information to cellular protein factories. This inhibition ultimately leads to a halt in the production of certain proteins, allowing normal cellular processes to continue.
