  • The Earth’s ozone layer is expected to recover within the next 40 years, according to a panel of international experts backed by the U.N. From the story: “The panel, which publishes a new ozone layer report every four years, credits the phasing out out of nearly 99% of ozone-depleting chemicals for the improvement.”

From the story: “The family took the tooth to the Calvert Marine Museum, which confirmed the fossil’s identity and shared the exciting news of the ‘future paleontologist’ on Facebook.”
