These elements would ultimately come to be known as isotopes, but at the time this concept was

Female postmortem brains contain more S-nitrosylated C3 proteins, likely linked to menopause, which instruct immune cells to kill neuronal synapses.
Oceans: Medicine Chests of the Future?
A. J. S. Rayl | Sep 26, 1999 | 7 min read
As disease resistance to antibiotics and other drugs continues to build, even new methods of discovery such as combinatorial chemistry may not be able to meet the ever-increasing need for more efficient and more effective compounds. According to a core group of researchers, however, an untapped reservoir of powerful new medicines is in the oceans. In fact, so rich is life in the oceans that some seafaring scientists go so far as to say the greatest bounty in the medicine chest of the new millen

Graphic: Leza BerardoneOne recent morning at the Applied Biosystems proteomics research center in Framingham, Mass., scientist Jason Marchese patiently used a pipettor to place tiny samples onto a 2-inch-by-2-inch plate. He was surrounded by technology as simple as 2-D gel electrophoresis apparatus and as cutting-edge as a high-throughput system that uses automated robotics for multidimensional liquid chromatography separation of proteins and an automated workstation that uses the latest in mass
