Major Player in Cell GrowthWhen cells go about the business of dividing, they can get sidelined. Maybe there aren't enough nutrients. Maybe there aren't the right signals to resume multiplying. Either way, cells go quiet.
What can restart cell division - the process that drives the development of embryos, the renewal of hair, skin and blood, and the creation of cancer - is a single transcription factor called GABP, as per new research from The Warren Alpert Medical........Go to the Cancer-blog (Added on 2/6/2007 9:41:03 PM)

Two Brains: Connected?The nerve cells of the brain are inter-connected to a complex network. All brain activities are the result of the "firing" of nerve cells, when they send electrical pulses - like a Morse code - to other cells of the brain.
