Researchers add to understanding of how brain cells communicate

...m ions through a channel in NMDA receptors plays a central role. Neurons "talk" to each other by releasing glutamate at a synapse that binds to NMDA receptors on the surface of the "listening" neuron. If the listening neuron is strongly excited, magnesium ions are expelled from the channel of NR1/2A recep...

...le of evolution this is incredibly fast for such a central process." To have a safety net when temporal control at the gene level fails, cells also regulate the activity of cell cycle proteins directly, switching them on and off and modifying them at particular sites. A closer look at these proteins reveale...

Aequorin was discovered in the 1960s and has been used in research for a long time as an indicator of calcium. But the protein has never been tried as a treatment to control calcium levels. Underwood believes hi...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat
