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 ...
Scientists refine the timeline of sponge origins, showing soft-bodied ancestors likely evolved later than some chemical ...
Scientists find that holes can also improve technology, including medical devices. The article describes an entirely new way to make a solar cell: by etching holes in the top layer to make it porous.
Sponge-like solar cells could form the basis for less-invasive pacemakers or similar medical devices
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 ...
What can sponges tell us about the evolution of the brain? Sponges have the genes involved in neuronal function in higher animals. But if sponges don't have brains, what is the role of these?
