This week our readers continued to show interest in the James Webb Space Telescope, especially a piece by astronomers Chris Impey and Daniel Apai of the University of Arizona that asks the exact question I’ve wanted answered. Now that the deep space telescope is up and running, will it help us humans find signs of life on other planets?

On the other side of the cosmic scale, the University of Virginia’s Kenneth Walsh writes about his new research on Y chromosome loss. This short story helps explain the aging process and suggests a possible reason men on average live shorter lives than women.

A couple of our editors’ picks are especially relevant for anyone feeling hot as they read this. That’s you, right? An article by Jessica Murfree and Natasha Brison of Texas A&M, experts on the legal aspects of sports, suggests that the way student athletes are trained needs a rethink as summer heat increases. University of Arizona economist Derek Lemoine explores how hot temperatures affect economies already reeling from inflation.

Next week, we’ll bring you coverage about the first polio case in the U.S. in nearly a decade and research-based ways to forge social connections.
