Salk scientists developed genetic tools that reveal how individual neurons control distinct, opposing behaviors in fruit flies. The study identifies a specific group of neurons that help suppress aggression in both male and female fruit flies. These findings provide a roadmap for understanding equivalent human neurological signaling, and help reveal how disruptions in signaling may contribute to brain dysfunction.

Research conducted at The University of Texas at Arlington is part of a global effort to address growing threats to coral reefs. The University recently sent researchers and students to the 16th International Coral Reef Symposium in New Zealand, the premier global conference for coral reef research, held every four years.

For the first time, researchers have used data from narwhals to document how Atlantic water reaches deep into fjords along Greenland’s east coast. A new study from the University of Copenhagen sheds light on a poorly studied region, and the findings could have important implications for understanding and predicting climate change.

Microplastics aren’t just a problem for oceans. Researchers found these tiny plastic particles in 95% of sediment samples from a protected freshwater wetland along Florida’s St. Lucie River. Nearly half were fibers, suggesting that synthetic textiles and other everyday materials may be contributing to plastic pollution in the preserve. Concentrations were highest near the river and a flood-control canal, suggesting water movement helps transport and concentrate pollution. Findings from the study underscore the need to address plastic pollution in wetland conservation and stormwater management.
