Sharks

Researchers have discovered 14 fossilized shark teeth belonging to five extinct species on the Abu Tartur plateau in Egypt. The findings confirm that this arid desert region was once a thriving marine ecosystem.

Researchers from the University of Delaware are equipping sharks with sensors to measure ocean temperature, depth, and salinity. The project aims to gather data that will improve hurricane intensity forecasts before they reach the US coast.

Sharks were spotted within a few days off the coast of New York, leading to nearly 50 beach closures since the start of the season. Now, the city police are operating a fleet of drones that broadcast real-time video from the air and warn lifeguards when they spot suspicious silhouettes in the water. "The lifeguard is constantly yelling 'Shark!'" describe bathers who are adapting to the new...
