The body has a veritable army constantly on guard to keep us safe from microscopic threats from infections to cancer. Chief among this force is the macrophage, a white blood cell that surveils tissues and consumes pathogens, debris, dead cells, and cancer. Macrophages have a delicate task. It's crucial that they ignore healthy cells while on patrol, otherwise they could trigger an autoimmune response while performing their duties.

In a new study, researchers created a sort of simulated voting booth -- a space where people, or mathematical 'agents,' with various biases could deliberate over decisions. The results may help to reveal the mathematics of how the human brain acts when it needs to make a choice.

Radiation is a powerful tool for treating cancer, but prolonged exposure can damage the skin. Radiation-induced skin injuries are painful and increase a person's chances of infection and long-term inflammation. Now, researchers report an aspirin-containing hydrogel that mimics the nutrient-rich fluid between cells and accelerates healing of skin damaged by radiation in animals. With further development, the new salve could provide effective and rapid wound healing for humans.
