The storm followed a sweltering summer in New York City, with a procession of heat waves nearing 100 degrees. For those who were pregnant at the time, enduring these extreme conditions wasn’t just uncomfortable—it may have left a lasting imprint on their children’s brains.

In a recycling facility in Covington, Georgia, workers grind up dead batteries into a fine, dark powder. In the past, the factory shipped that powder, known in the battery recycling industry as black mass, overseas to refineries that extracted valuable metals like cobalt and nickel. But now it keeps the black mass on site and processes it to produce lithium carbonate, a critical ingredient for making new batteries to power electric vehicles and store energy on the grid.

Every few years, a Silicon Valley gig-economy company announces a “disruptive” innovation that looks a whole lot like a bus.

Male fertility rates have been plummeting over the past half-century. An analysis from 1992 noted a steady decrease in sperm counts and quality since the 1940s. A more recent study found that male infertility rates increased nearly 80% from 1990 to 2019. The reasons driving this trend remain a mystery, but frequently cited culprits include obesity, poor diet, and environmental toxins. Infectious diseases such as gonorrhea or chlamydia are often overlooked factors that affect fertility in men.
