RNA polymerase gets very pushy

Article Abstract:

A study of the RNA polymerase chain showed that it has a strength of 14 piconewtons and efficiently uses pyrophosphates for fuel. These features account for the ease with which the chains seem to move along a DNA strand. The most difficult spot the RNA chain has to move is on the helix chain.

Neuronal adhesion molecules signal through FGF receptor

Article Abstract:

Researchers have discovered that specific cell adhesion molecules (CAMs) initiate some cellular events needed for neurite outgrowth by activating the receptor for fibroblast growth factor (FGF). CAMs seem to 'highjack' another molecule's receptor in order to signal.
