Using drones, 17 distinct behaviors of narwhals were captured in the wild. Findings reveal complex behaviors of the Arctic’s iconic whale never seen before. This highly gregarious whale uses its tusk to investigate, manipulate and influence the behavior of a fish, the Arctic char. The study also provides the first evidence of play, specifically exploratory-object play, and the first reports of kleptoparasitism, a “food thief” situation, among narwhals and glaucous gulls.

An Osaka Metropolitan University-led Egypt-Japan research team found E. coli prevalent in over 25% of popular milk and dairy products in Egypt and discovered that one of the strains isolated there in 2018 had the same properties as the E. coli that caused food poisoning in more than 1,800 schoolchildren in Japan in 2021.
