Anthony Patt of Boston University and his colleagues organized short workshops for a randomly chosen cross-section of subsistence growers—those who plant crops...

Famous for their capacity to turn into any type of nerve cell, adult neural stem cells can also serve as anti-inflammation police in the brain, researchers have found. When injected into mice with an inflammatory brain disorder similar to multiple sclerosis, these versatile cells home in on and destroy certain bloodborne inflammatory immune cells.

In addition to serving as a source of...
