Immune system 'escape hatch' gives cancer cells traction

.... By explaining some of the precise biological workings of MDSCs in cancer the teams findings suggest why experimental cancer vaccines have to date been plagued by T-cell tolerance, a weakened rather than strengthened immune response, says Jonathan Schneck, M.D., Ph.D., one of the studys authors. Our fi...

TU Delft tracks the influence of a cancer inhibitor on a single DNA molecule

Dartmouth professor makes case for ethically universal stem cell lines

...al to become more specialized, contributing to the workings of a wide variety of organs and tissues. Their potential to treat diseases such as Parkinsons is slow to be realized because of the ongoing ethical debate over harvesting hESCs, a process called deriving hESC lines. Additionally, its a politically ch...

Math that powers spam filters used to understand how brain learns to move our muscles

...t outcome is uncertain. The idea as applied to the workings of a brain is that each brain uses what it already knows to predict or believe that something new will happen, then uses that information to help make it so. We used the idea that prior experience and belief affect the probability of future outcome...
