Banded mongooses form battle lines in Queen Elizabeth National Park, Uganda. When families of banded mongooses prepare to fight, they form battle lines. Each clan of about 20 animals stands nose to nose, their ears flattened back, as they stare down the enemy. A scrubby savannah separates them, until the first animals run forward.

Why is ‘mongoose warfare’ waged?

More than a million tons a year of America’s plastic trash isn’t ending up where it should. The equivalent of as many as 1,300 plastic grocery bags per person is landing in places such as oceans and roadways, according to a new study of U.S. plastic trash. Read story

A silverback mountain gorilla named Segasira walks in the Volcanoes National Park in Rwanda. These large vegetarian apes are generally peaceful, but as the number of family groups in a region increases, so does the frequency of gorilla family feuds, according to a new study published in the journal Science Advances.

This Sept. 1, 2020 photo provided by San Diego Zoo Global shows Kurt, a tiny horse who is actually a clone. Little Kurt looks like any other baby horse as he frolics playfully in his pen. But the 2-month-old, dun-colored colt was created by fusing cells taken from an endangered Przewalski&#039;s horse at the San Diego Zoo in 1980. The cells were infused with an egg from a domestic horse that gave birth to Kurt two months ago. The baby boy was named for Kurt Benirschke, a founder of the San Diego Zoo&#039;s Frozen Zoo, where thousands of cell cultures are stored. Scientists hope he&#039;ll help restore the Przewalski&#039;s population, which numbers only about 2,000.
