A Peruvian trial of underwater sound devices called pingers reduced bycatch of dolphins by 83%, but failed to deter humpback whales. The study found that lower-frequency pingers may be needed to address whale interactions.
Researchers from Tokyo Metropolitan University found that a foam's liquid amount and extent determine its draining mechanism. They identified universal thresholds for different foams, promising clear design principles for new materials.
A global study by Monash University found that large daily temperature variations increase the risk of heat-related deaths, with fluctuations in Central Europe posing a significant threat. The research highlights the importance of considering temperature variability in heat-related mortality studies.
