The Amazon is often treated as a single forest, yet the risks its people face from extreme weather vary sharply across borders.
A new analysis by researchers from Brazil, Ecuador, Bolivia, Colombia and the United States suggests those risks are also widely undercounted.

Weather disasters are surging in the Amazon. Reporting isn’t.
The Amazon’s climate hazards are growing faster than governments can track.

Tiny and mysterious shrew studied at Stony Brook for clues to brain health
A shrew's brain and other organs can shrink by as much as 30% and then grow back in the spring. Once the brain of a human being shrinks, it remains in that state.
