The first-place photo (above) is the foot of an embryonic lizard—Phelsuma grandi, a Madagascar giant day gecko—created by Grigorii Timin at the University of Geneva under the supervision of biologist Michel Milinkovitch. Hundreds of images, representing 200 gigabytes of data, were stitched together to show nerves (in cyan), bones, blood cells, and other tissues. Even though the foot is only about 3 millimeters long, acquiring all those images took more than two days, Timin said in a news release. And if movement in miniature tickles your fancy, be sure to check out the top videos from the 2022 Small World in Motion Competition, too.
