Key to 'curing' obesity may lie in worms that destroy their own fat: McGill researchers
This release is available in French .
A previously unknown mutation discovered in a common roundworm holds the promise of new treatments for obesity in humans, McGill University researchers say. Their study was published Dec. 3 in the journal Nature , and was funded by the Canadian Cance...
