As corals face threats from warming oceans, a new study uses modern genetic-sequencing tools to help reveal the relationships between three similar-looking corals.

A group of young marine-disease researchers from around the country has contributed key information about sea stars’ immune response when infected with a virus that is thought to cause a deadly wasting disease. It’s the first time researchers have tracked how genes behave when encountering this naturally occurring pathogen, which could help explain how sea stars attempt to fight the virus and why they develop lesions and appear to melt.
