Cell death: How a protein drives immune cells to suicide

For some pathogens, attack is the best form of defense—they enter immune cells of the human body. However, if they are detected in their hidden niche, the infected cell kills itself to re-expose the pathogens. In the EMBO ...

Decisive steps in the initiation of programmed cell death revealed

New technology to make implant surgery outcomes more successful

(Phys.org)—Swiss cell biologists at Empa want to "tune" implants such that they can better carry out their tasks in the human body. The surface of the implant is the key to success. Together with the Fraunhofer Institute ...

Climate change: More carbon dioxide leads to fewer clouds

(Phys.org)—The warmer the air, the more water can evaporate: a simple relationship familiar to us from everyday life. Researchers from Germany and the Netherlands have now established that this is not always the case: although ...
