Researchers from the US determined the species of 29 samples of shark meat bought in shops or online. 93% had been labeled ambiguously as ‘shark’, and 31% overall were from four endangered or critically endangered species. Several of these species are known to contain dangerous levels of heavy metals. The authors call for better regulation of labeling and greater consumer awareness.

In fields ranging from cybersecurity to autonomous vehicles testbeds provide realistic environments where innovations can be safely piloted before widespread deployment. TOPSAIL, developed by Indiana University and leading educational technology company Instructure and funded through a planning grant from the National Science Foundation, will bring this proven methodology to education research for the first time, creating infrastructure that enables research teams to conduct pilot evaluations in authentic classrooms responsibly, rigorously, and rapidly.

Dong Zhang, an assistant professor at the University of Oklahoma, has been awarded a CAREER Award by the National Science Foundation to study next-generation batteries. Key questions the research will explore include understanding mechanical stress generation and volume changes in silicon and graphite particles during charging and discharging, and how these interactions drive battery long-term degradation.

Domestic vessels account for the majority of port visits globally. Inspecting them in addition to foreign vessels is key to deterring illegal fishing, scientists say.
