In a Southern California aquarium, a young leopard shark rushes headfirst toward a plastic squid toy and then—as if in a game of chicken—makes a last-minute dash to the left, barely clearing the dangling rubber tentacles. Meanwhile, his tankmate, a California skate, grabs an orange ring with her mouth, rolling the textured plastic around with her tongue. And over at the tank’s sandy bottom, a hovering horn shark glides over to a bright yellow hoop and squeezes himself—along with all his jutting fins—right through it.

These cartilaginous fish aren’t putting on a show. It seems they’re playing—just for the fun of it, according to the team behind the new study.

The findings, the researchers say, offer the strongest evidence yet that sharks engage in play behavior.

In one of the first trials, a new approach induced in vivo CAR-T cells in four patients with multiple myeloma—a blood cancer—and evicted the malignant cells from their bone marrow.

Novel approach could be faster, and cheaper, than making the cells in the lab—but safety concerns linger

The domestic cat may be a far more recent arrival to Europe than previously thought, arriving roughly 2000 years ago and not because of the Paleolithic expansion of Near East farmers.

The findings in Science offer new insight into one of humanity’s most enigmatic animal companions and identify North Africa as the cradle of the modern housecat. https://scim.ag/4pwSufc
