Serotonin-releasing neurons (green arrows) from the dorsal raphe nucleus (DRN) penetrate many other areas of the brain, including the nucleus accumbens (NAc), orbitofrontal cortex (OFC) and medial...

(Left) The graph shows that on average, present-day hurricanes weaken more slowly than hurricanes did 50 years ago. (Right) This slowing of intensity means that on average, present-day hurricanes are...
