How asteroids bombarded Earth and built the continents, reports Big Think. “New research presents significant evidence to demonstrate that the oldest continental remnants were formed after massive asteroid impacts. The breakthrough adds legs to a long-standing theory and holds implications for how life may develop on other planets.”

Scientists Uncover New Physics in the Search for Dark Matter, reports SciTechDaily–““It’s been something like a detective story,” said Wolfgang Mittig, a Hannah Distinguished Professor in Michigan State University’s Department of Physics and Astronomy and a faculty member at the Facility for Rare Isotope Beams, or FRIB. “We started out looking for dark matter and we didn’t find it,” he said. “Instead, we found other things that have been challenging for theory to explain.”

How many people can Earth handle? asks BBC Future. “BBC Future takes a look at one of the most controversial issues of our time. Are there too many of us? Or is this the wrong question? “Back in 1993, a team of American researchers studied the human genome for clues to its deep past, and discovered the tell-tale signature of a major “population bottleneck” – a moment when humanity shrank so drastically, all subsequent generations outside Africa were significantly more closely related.”
Human brain cells made fewer genetic mistakes than Neanderthals –Despite the fact that both species shared a similarly large neocortex, scientists still have many questions about how closely the function of their brains resembled our own, reports Big Think. “A recently published study reveals that several amino acids in the human brain — which only emerged after humans split away from Neanderthals — make our chromosomes far less prone to errors as they separate into identical pairs. “
Astronomers spot 2 intriguing Super Earths around ultracool star–The newly discovered planets orbit an ultracool dwarf star and one is in the habitable zone, making it a prime target for further investigation, reports Space.com.
What happened to the world’s ozone hole? asks KIra Walker for BBC Future. “Back in the 1990s, the hole in the planet’s ozone layer was a pressing global crisis – if we had ignored it, today there would be several.”
