Whale carcass yields bone-devouring worms
...t evolutionary strategy-they break down whale-bone lipids
(fats and oils) directly to provide food for the worms. This is the first time that a lipid-degrading bacteria has been observed in a symbiotic relationship. Co-author Goffredi has been studying this relationship and is currently preparing a separate...

to T cells. This protein is indispensable for the generation of NKT cells. The researchers state that the work provides insight into how signals from outside the cell can influence differentiation and gene expression and is an entry point for ...
In the obese, metabolic adaptations post-weight loss lead to regaining of shed pounds
