An organic approach to pest control: releasing super-sexed (but sterile) male insects

15 years ago from Science Daily

An improved method for sustainable pest control using "super-sexed" but sterile male insects to copulate with female ones is being developed by agricultural researchers in Israel. The scientists thus hope...

Brain-Like Computer Closer to Realization

15 years ago from Physorg

(PhysOrg.com) -- Almost since computing began, scientists and technologists have been fascinated with the idea of a computer that works similarly to the human brain. In 2008, the first "memristor"...

New microscopy technique offers close-up, real-time view of cellular phenomena
