A protein known for circulating in the blood to fight infection plays a very different role when produced by cells inside tumors. A protein that emerged long before animals developed circulatory systems may influence whether cancer immunotherapy succeeds. Researchers at Nagoya University in Japan found that complement C3 helps keep immunosuppressive cells out of tumors, [...]

Silver nanoparticles provide a more efficient way to cut and assemble DNA, improving recovery rates and boosting DNA joining efficiency for future gene engineering applications. DNA is made of long chains that carry the instructions living things need to grow and function. In genetic engineering, researchers cut DNA at chosen locations and attach the pieces [...]
