Unveiling the Role of Plankton Super Swimmers in the 2020 Red Tide Event

A study led by scientists at UC San Diego's Scripps Institution of Oceanography and Jacobs School of Engineering has revealed how the historic red tide event of 2020 off Southern California was fueled by the exceptional swimming ability of a plankton species called Lingulodinium polyedra. These dinoflagellates were able to create an exceptionally dense bloom due to their vertical migration, swimming upward during the day to photosynthesize and downward at night to access nutrients. The study validates a 50-year-old hypothesis and highlights the importance of understanding phytoplankton behavior and changes in the coastal environment to predict and mitigate harmful algal blooms.

Discovery of Ancient Viruses in Coral Symbionts' DNA.

Scientists have discovered remnants of ancient RNA viruses in the DNA of symbiotic organisms within reef-building corals, shedding light on viral infections in corals and their symbiotic partners known as dinoflagellates. The RNA fragments are from viruses that infected the symbionts as long ago as 160 million years. The discovery could help scientists understand how corals and their partners fight off viral infections today and provide clues that can help scientists better understand the ecological and economic impact of viruses on reef health.
