Jump-starting T Cells In Skin Cancer
...f skin cancer, can be successfully treated in some cases
by vaccinating patients with tumor proteins. How these vaccines work and why they are only effective in some patients remains unclear. Pierre Coulie and colleagues now show, in two articles in the January 17 issue of the Journal of Experimental Medic...
Growth in the sea comes down to a struggle for iron

other bacteria have figured out ways to get the iron from molecules that they didn't produce. So, they can pirate that iron. It's beginning to look like the same thing may be happening in the ocean," Wells explains. In July, by the time Wells and his...

a very strong, statistically meaningful swelling in the neurons." The researchers tested whether they could enhance the pathology they observed in the mice and humans by reducing the levels of a key transport protein, kinesin-1, the cell's principal...
Scientists Replicate Hepatitis C Virus in Laboratory
