From wikipedia (click for source)

As #SciAmFood week draws to a close, we’ve heard a lot about the food we consume, from not getting enough to astronaut nutrition (and getting too much) to tricking your brain about what it’s getting.

Our hand soap, dish soap, and body wash have morphed into an arsenal of bug-killing napalm, eliminating all but the heartiest of bacteria.

The immune system’s cells work hard to fight off infections. But new research is uncovering their important role in cognition, and a study published online May 3 in The Journal of Experimental Medicine reveals how the immune system’s T cells, which aren’t present in the brain, can impact learning and memory. Inflammation around the brain [...]
