Captive male Asian elephants can live together peacefully and with little stress, if introduced slowly and carefully, per Laos case study of 8 unrelated males

Researchers documented an unusual feeding aggregation of oceanic whitetip and tiger sharks scavenging concurrently on a carcass off the coast of Hawaii's Big Island. The study reveals that despite their different habitats, these shark species can peacefully coexist and establish a social hierarchy.

Researchers discovered Asian elephants have significantly heavier brains, weighing 5,300 grams on average, compared to 4,400 grams in African elephants. Elephant brains grow almost as much as human brains after birth, with a threefold increase in weight by adulthood.

Researchers analyzed the teeth of four European straight-tusked elephants, discovering they migrated up to 300km before reaching their final habitat. The study suggests organized hunting and cooperation between Neanderthals and the elephants.

Elephants released from human care successfully reintegrate into the wild, exhibiting behaviors comparable to those of their wild neighbors. While some individuals show age- and sex-related differences, overall, rewilded elephants adapt well, with most stress levels within normal ranges.

A new study published in the American Heart Association's Hypertension Journal highlights distinct blood pressure patterns among East and South Asian adults living in the UK. Researchers found that South Asian adults face high blood pressure-related heart risks earlier in life, while East Asian adults see risks rise in later years.

A study by researchers at Kyoto University found that Asian elephants understand the importance of visual attention for effective communication. The elephants gestured most when both the experimenter's body and face were oriented towards them, suggesting they use a combination of cues to recognize human visual attention.
