A Brazilian city devastated by COVID-19 may have reached herd immunity
Up to half of Manaus was infected at the epidemic’s peak, which slowed further spread of the virus but also led to many deaths, scientists say.

A beaked whale’s nearly four-hour-long dive sets a new record
The animals may rely on large stores of oxygen, a slow metabolism and the ability to tolerate lactic acid to go for hours without surfacing for air.
- Climate
Global warming may lead to practically irreversible Antarctic melting
Simulations suggest that even if the Paris climate goals are met, melting Antarctica ice will still cause sea levels to rise by more than 2 meters.
