Algae, like humans, suffer from too much sun. With rising UV radiation due to ozone depletion, algae develop protective strategies like producing MAAs. On Spitsbergen, scientists study how UV and warming waters threaten algae and marine ecosystems.

Scientists have discovered a new giant clam species, Tridacna costata, in the Red Sea. Once dominant, it's now nearly extinct—likely the first case of human overfishing 125,000 years ago. Genetic and fossil studies confirm its unique identity.
