Trio Share Medicine Nobel

Arvid Carlsson, Paul Greengard and Eric Kandel won the Nobel Prize in medicine for their discoveries concerning how messages are transmitted in the nervous system, work that has paid off for treating Parkinson’s disease.

The three Nobel laureates will share the $915,000 prize for their pioneering discoveries concerning one way brain cells send messages to each other, according to the award citation.

These discoveries have been crucial for an understanding of the normal function of the brain. In addition, it laid the groundwork for developing the standard treatment for Parkinson’s disease and contributed to the development a class of antidepressants that includes Prozac, the Nobel Assembly at Karolinska Institute said today.

Carlsson, 77, is with the University of Goteborg in Sweden, Greengard, 74, is with Rockefeller University in New York and Kandel, 70, is an Austrian-born U.S. citizen with Columbia University in New York.

More to Come

The winners of the prizes for physics and chemistry will be announced Tuesday and for economics — the only one not established in Nobel’s will — on Wednesday in Stockholm.

The awards culminate Friday with the coveted peace prize in Oslo, Norway.

Carlsson’s studies during the late 1950s led to the discovery of the drug L-dopa, used to treat Parkinson’s disease, which is still the most important treatment for the disease, the committee said.

Greengard was awarded for his discovery of how dopamine and other chemical messengers shuttle messages between brain cells. Kandel was cited for his research on the biology of memory, showing the importance of changes in the synapse, a tiny gap between brain cells where messages are transmitted.

Suspense Over Literature

This year’s award for medicine was bumped to the top slot after the academy failed to reach a decision last week on the literature prize — usually the first announced.

The Swedish Academy, which traditionally keeps the date of the literature prize secret until a couple days before it announces the winner, has not set a time yet, but it is always a Thursday, usually in October.

The suspense for the literature award was heightened last week when the academy failed to reach a decision.

Alfred Nobel, the Swedish industrialist and inventor of dynamite, left only vague guidelines in his will establishing the prizes. The selection committees deliberate in strict secrecy.

Peace Prize Hints

The only public hints available are for the peace prize. The five-member awards committee never reveals the candidates, but sometimes those making the nominations announce their favorites.

This year that includes President Clinton and former President Jimmy Carter for wide-ranging peace efforts, as well as former U.S. Sen. George Mitchell for his efforts to resolve conflict in Northern Ireland.

Other reported nominees are former Finnish President Martti Ahtisaari and former Russian Prime Minister Viktor Chernomyrdin for their Balkan peace efforts; South Korean President Kim Dae-jung for promoting good relations in Asia; and a town, northern Albania’s Kukes, for accepting 150,000 refugees during the Kosovo conflict.

The literature and peace laureates are usually the most visible, but the new adjectives “Nobel winner” often also bring scientists more attention from outside their laboratories.
