Nobel Prize Winner Dies at 85

Posted by: biologyblog | December 12, 2008 | 2 Comments |



Daniel Carleton Gajdusek
(9/9/1923 – 12/12/2008)
was an American physician, medical researcher and corecipient (with Baruch S. Blumberg) of the 1976 Nobel Prize for Physiology or Medicine for his research on the causal agents of various degenerative neurological disorders involving prions.

During the 1950s, Gajdusek traveled to New Guinea to research an unusual disease that was killing members of a native tribe called the Fore.

Gajdusek discovered that these tribe members were engaging in endo-cannibalism, the practice of eating members of one’s own tribe. This unusual habit enabled tribe members to add much needed protein to their diet, after the victim had died of natural causes. Upon inspection of the victim’s brains, Gajdusek discovered holes in the brain tissue that resembled sponges. He coined the term transmissible spongiform encephalopathy. He discovered that once the tribe members stopped their cannibalistic ways, the disease went away. He wrote several papers on this new discovery, and things remained rather quiet on this subject until the mid-1980s, when the disease reared its ugly head in cattle in Great Britain.


In the early 1980s, a new epidemic called Mad Cow,
or Creutzfeldt-Jacob (CJD) struck England .  146 died people in England which resulted in the slaughter of millions of cows, and almost crippled the cattle and dairy industries. The incubation period of Mad Cow Disease, , could be as long as 25 years. Mad Cow Disease, or CJD, is incurable and 100 percent fatal.

I think this article is very interesting & very funny in a way. The tribe ate each other? It seems very disturbing how some one you are close with will eat you when you pass away. As Gajdusek discovered, the cannibals have suffered from a disease as they ate other humans. When they stopped, there was no more disease. Wouldn’t it just make sense by eating the same species you’ll get sick? Common sense please. lol(:

This researcher was clearly a humanitarian. he decided to look into other peoples eating habits such as cannibalism. By eating their own new diseases began to appear. Gajdusek was able to determine that the diseases were due to “prions” as he named them which were similar to tiny viruses. I can’t imagine eating another human but I believe Gajduseks work was very important.
