Research identifies 3D structure of key nuclear pore building block

Guarding access to the nuclear chamber is the job of large, intimidating gatekeepers known as nuclear pore complexes (NPCs), which stud the nuclear membrane, filtering all of the biochemical information passing in or out. In new research, scientists have for the first time glimpsed in three dimensions an entire subcomplex of the NPC.

Scientists studying the 'colossal magnetoresistance effect'

Millions of people today carry around pocket-sized music players capable of holding thousands of songs, thanks to the discovery 20 years ago of a phenomenon known as the 'giant magnetoresistance effect,' which made it possible to pack more data onto smaller and smaller hard drives. Now scientists are on the trail of another phenomenon, called the 'colossal magnetoresistance effect' which is up to a thousand times more powerful and could trigger another revolution in computing technology.
