A blue pig with a red kidney is on the left-hand side of the image. A translucent human torso with black organs (except the left kidney, which is red). Red square outlines frame the kidneys, both in the pig and the human, indicating the interspecies organ transplant. A vertical, grey double-stranded DNA is at the center of the image, indicating the alpha-gal genetic modification in pigs, which has significantly improved xenotransplantation outcomes.

Multiple dinosaurs walk across a lush valley landscape. Several pterosaur-like creatures roam the sky, and two trees frame the image, as a hill looms in the background.

Why Were Dinosaurs So Big?

A grey tabby and white cat sits on a brown marbled floor, leaning to its side, in front of a yellow wall. Next to the cat sits an empty glass and a nearly empty bottle of brown liquid that seems like hard liquor. The cat’s eyes are half-open, with contracted pupils, making it seem, anthropomorphically, intoxicated.
