Injecting coral. Marine microbiologist Raquel Peixoto is deep in concentration in this underwater shot, tending to the coral species that she studies at the King Abdullah University of Science and Technology in Thuwal, Saudi Arabia. Here in the Red Sea, she’s applying a cocktail of bacteria to a reef — known as the Coral Probiotics Village in the lab — to study the symbiotic relationship between the two underwater life forms. The photo was taken in October 2021, and it’s hot down there: the water temperature can reach up to 32 °C.
