As ocean waters warm, a race to breed heat-resistant coral

Around the world, researchers are working on a range of projects that aim to enhance corals’ resistance to marine heat waves. In a promising sign, a U.K. team recently became the first to quantify an uptick in heat tolerance among adult corals selectively bred for the trait.

This image of NASA's Ingenuity Mars Helicopter was taken by the Mastcam-Z instrument of the Perseverance rover on June 15, 2021, the 114th Martian day, or sol, of the mission. The location, "Airfield D" (the fourth airfield), is just east of the "Séítah" geologic unit.
