Major Player in Cell Growth

Major Player in Cell Growth
When 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)

Secret Of 1918 Influenza Virus

Secret Of 1918 Influenza Virus
In a study of non-human primates infected with the influenza virus that killed 50 million people in 1918, an international team of researchers has found a critical clue to how the virus killed so quickly and efficiently. The group was led by University of Wisconsin-Madison virologist Yoshihiro Kawaoka, and includes Michael Katze, professor of microbiology at the University of Washington, and colleagues here.

Two Brains: Connected?

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. This process depends on the exact dynamics of the neuronal activity. When the brain receives sensory input, calculates or remembers, it processes information encoded in a series of neuronal impulses in different nerve cells.........Go to the Neurology news blog (Added on 2/5/2007 9:32:43 PM)
