Portugal is one of the most vulnerable countries in Europe to climate change. Straddling the Mediterranean and eastern Atlantic regions, it’s part of a climate change hot spot. Some of the biggest fuels are shrubs. One study found that shrubland covers 1.6 million hectares in Portugal—about 18 percent of the nation’s land area. And those shrubs are gaining ground.

He recently published an op-ed in Scientific American called  "Here's What I Learned as the U.S. Government's UFO Hunter". Learn more about your ad choices. Visit megaphone.fm/adchoices

We all have our tricks for sobering up after a night of drunken revelry: maybe a pot of black coffee or an ice-cold shower. But for mice in a certain lab in Texas, all it takes is a shot.
