New Discovery About Formation of New Brain Cells

ScienceDaily (Nov. 23, 2009) — The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells.

Saving The Single Cysteine: New Antioxidant System Found

Medical News Today, Article Date: 23 Nov 2009 - 1:00 PST
We've all read studies about the health benefits of having a life partner. The same thing is true at the molecular level, where amino acids known as cysteines are much more vulnerable to damage when single than when paired up with other cysteines.  read more....
