...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.

...'s increased traffic flow, there's never a traffic jam 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 next step was to analyze the amount of Hmox enzyme expressed in white blood cells and in epithelial cells lining the grafted trachea. "We did this to determine the source of CO," Pinsky says.

In a vicious cycle, the traffic jam also could increase production of an abnormal protein that clogs neurons, leading to their failure and eventual death.
