Study illuminates cues algae use to ‘listen’ to their environment
Plants have long been known to release chemicals to respond to stress and relay information to their neighbors. A team of scientists from Bigelow Laboratory have shown that glaucophytes, a small group of single-celled algae distantly related to plants, appear to have the same penchant for chemical communication. This suggests ...

We should help coral microbial symbionts evolve heat tolerance in the lab, researchers say
Researchers discuss the potential of improving corals’ chances by inducing the evolution of heat tolerance in their symbionts—the mutualistic microbes that provide corals with nutrients in exchange for shelter and that are expelled during coral bleaching.
