digitaltrends.com – A milestone in the development of the early universe was the combination of helium and hydrogen atoms into a molecule called helium hydride. It would be expected that helium hydride would still be present in some parts of the universe. But strangely enough, it has never been detected in space before now.

A study published Wednesday in Nature reports a team restored some function in brains removed from pigs that had been dead for four hours. The technology still has a long way to go, but might eventually restore damaged brain cells in human patients.
