Summary: A new study shows how math helps explain why babies nap erratically, teens stay up late, and older adults wake earlier. Researchers expanded the classic two-process sleep model by adding the ...

First emerging in Japan in the Asuka period of about 538 to 710 C.E., the intricate woodworking practice of kumiko has since spread worldwide. Once reserved for screens or inlaid panels in handmade ...

For centuries, humans believed they held a monopoly on geometric intuition. The ability to recognize structure in a shape – its right angles, symmetry, and parallel lines – was seen as a mark of human ...

Crows are able to look at a handful of four-sided shapes and correctly distinguish those that exhibit geometric regularity from those that don't, according to a provocative new study. It's the first ...
