The sea, like the land, has heat waves—periods of elevated sea surface temperatures with profound impacts on marine life. A modeling study finds that nearly half of extreme marine heatwaves since 1940 are likely due to global warming. In PNAS: ow.ly/PtOL50VEIrB

The global marine heatwaves of 2023 were unprecedented in their intensity, persistence, and scale, according to a new Science study. The findings provide insights into the region-specific drivers of these events, linking them to broader changes in the planet’s climate system.

Some archaea—an ancient group of microorganisms—have an entirely novel genetic code, according to a new study in Science. Their genetic code reassigns a DNA “stop” signal to incorporate the rare amino acid pyrrolysine into their proteins. The findings expand our understanding
