The Incredible Awsomeness of JELLYFISH

fascinating research that just won the Nobel Prize'08:

STOCKHOLM, Sweden — Two Americans and a U.S.-based Japanese scientist won the Nobel Prize in chemistry on Wednesday for research on a glowing jellyfish protein that revolutionized the ability to study disease and normal development in living organisms.

Japan's Osamu Shimomura and Americans Martin Chalfie and Roger Tsien shared the prize for discovering and developing green fluorescent protein, or GFP, the Royal Swedish Academy of Sciences said.

Researchers worldwide now use GFP to track such processes as the development of brain cells, the growth of tumors and the spread of cancer cells. It has let them study nerve cell damage from Alzheimer's disease and see how insulin-producing beta cells arise in the pancreas of a growing embryo, for example.

The academy compared the impact of GFP on science to the invention of the microscope. For the past decade, the academy said, the protein has been "a guiding star for biochemists, biologists, medical scientists and other researchers."

When exposed to ultraviolet light, the protein glows green. So it can act as a tracer to expose the movements of other, invisible proteins it is attached to as they go about their business. It can also be used to mark particular cells in a tissue and show when and where particular genes turn on and off.
