Over the past twenty years, coral reef restoration has seen unprecedented growth worldwide. From Indonesia to the Caribbean, thousands of projects have been launched with the goal of "saving" coral reefs—often by planting coral fragments or building artificial reef structures.
UC San Diego researchers combined artificial intelligence with molecular biology to unravel how immune cells in the gut decide between inflammation and healing, a process gone awry in Crohn’s disease. They discovered that the NOD2 gene’s interaction with a protein called girdin
Physicists have uncovered how direct atom-atom interactions can amplify superradiance, the collective burst of light from atoms working in sync. By incorporating quantum entanglement into their models, they reveal that these interactions can enhance energy transfer efficiency,
