Volvox barberi actively organize themselves into large colonies that optimize space.

The finding could lead to a new way of producing “green” alternatives to fossil fuels.

Soluble adenylyl cyclase measures and responds to pH changes in coral cells, but whether it can help the animals withstand ocean acidification is not yet known.

True to its name, the corrugated coral's (Pavona varians) skeleton forms intricate patterns of alternating ridges and furrows.
