Mechanism for memory revealed in neurons of electric fish
...rs when the fish are close to each other. They can jam
each other's electrical signals. In response, one of the fish will jump to a higher frequency to avoid the jamming signal, emitting more electrical pulses per second than its neighbor. Oestreich and Zakon found that once the jamming avoidance has st...
'Computer-chemistry' yields new insight into a puzzle of cell division
...lopment of various cancers. Anti-cancer drugs that jam
the enzyme, preventing its docking with the kinase, could halt cell over proliferation to treat such cancers. However, developing such drugs has been hampered by lack of detailed understanding of how the Cdc25s fit with their associated kinases. "To...
UCSB researchers discover that the cell's endosomes use a surprising transportation system

on the microtubules. While it has long been known that endosomes travel in a bidirectional way, it has not previously been established that the transport system is symmetrical. The authors believe that because a number of neurological, muscular and c...
