The oldest type of molecule in the universe has been located at last

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.

Neuroscientists just brought pig brain cells back to life, changing our view of death

popsci.com – Scientists have successfully revived dead pig brains—at least partially. 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.
