NASA and Russian space officials stressed Thursday, Aug. 30, 2018, that the six astronauts are in no danger after a small air leak developed in one, at left, of the two Soyuz capsules docked at the space station. Russian officials say the leak was detected Wednesday night and may be the result of a micrometeorite impact. Both the crew and ground controllers are working hard to isolate the leak. (NASA via AP)

In this 2013 photo provided by Bogdan Onac, researcher Vasile Ersek stands in the Ascunsa Cave in Romania. Scientists say ancient shifts in climate helped our species replace Neanderthals in Europe. Researchers used data from this cave and another to document two lengthy cold and dry periods. The report, released Monday, Aug. 27, 2018, by the Proceedings of the National Academy of Sciences, found these periods coincided with the disappearance of Neanderthals and the arrival of our species in specific places.
