DNA building blocks on asteroid Ryugu, bacteria that eat plastic waste, and more science news

Remember when Japan sent a spacecraft to an asteroid 180 million miles away to scoop some dirt off the surface? Six years on from its arrival to Earth, that sample has yielded some insights about what may have seeded life on our planet. Read on to learn more about the latest findings, and other science news we found interesting this week.  DNA ingredients on RyuguIn 2020, a capsule from the Japanese space probe Hayabusa2 returned to Earth with samples collected from the surface of asteroid Ryugu, and scientists have spent the subsequent years analyzing those materials for clues about the conditions that existed in the early solar system. This week, researchers from Japan reported an exciting discovery: the Ryugu samples contain the five building blocks of DNA and RNA. The findings, coupled with those from other recent studies, could put us closer to understanding how the ingredients for life first made it to Earth billions of years ago. The study, published in the journa
