Scientists have pinned down the origins of the moon’s thin atmosphere, finding that it is primarily a product of “impact vaporization.” In other words, the barely-there lunar atmosphere is likely a product of meteorite impacts over billions of years.

EAPS researchers have identified a human “fingerprint” in the upper troposphere’s increasing ozone. “Now we can do more detective work and try to understand what specific human activities are leading to this ozone trend,” Arlene Fiore says.

The MIT spinout that brought the world no-stick toothpaste is moving into the medical space, starting with an ostomy pouch lubricant that could improve millions of lives. “Deploying this technology to solve difficult problems has been a dream,” Kripa Varanasi says.

A new method for producing hydrogen fuel uses recycled aluminum, saltwater, and coffee grounds. “This is very interesting for maritime applications like boats or underwater vehicles because you wouldn’t have to carry around seawater,” Aly Kombargi says.
