In this week’s Science Quickly news roundup, we dive into NASA’s new discovery of organic molecules on Mars, including some that have never been found there before. We also explore how human migration may have been shaped by a surprising factor: malaria. Plus, we go over the encouraging results of a new study that links declines in youth suicides in the U.S. to the adoption of the three-digit 988 Suicide & Crisis Lifeline in 2022. And finally, we’ll turn to some interesting findings about AI voice clones.
