When a malignancy or chronic infection sets in, a kind of immune combat fatigue can follow. Finding ways to recharge immune cells can restore their ability to fight deadly diseases, says immunologist John Wherry.
Scientists are finding that microscopic membranous bubbles called extracellular vesicles transmit messages from cells and do big jobs in many areas of biology — plus they might be useful for therapies.
Psychologists are seeking better ways to cut the link between dire thoughts and fatal action. Among their strategies: individualized plans for pulling back from the brink, and limiting access to deadly means, especially guns.
