Sponges lack anything resembling brains, but they nevertheless may have played a key role in the early evolution of the nervous system. A new study finds that sponges contain cells that have some of ...
Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn’t be flexible enough to bend into small crevices, or to sop up the perfect ...
Sponge-like solar cells could form the basis for less-invasive pacemakers or similar medical devices
