Much of the country has been enduring a heat wave this week, with millions sweating from Maine to the Midwest. But describing exactly how hot it is—and when temperatures become hazardous—can be challenging. Beyond the basic temperature, there’s the heat index, invented in 1978, which incorporates humidity measurements and is supposed to give a better indication of how a person might feel outside. Some health researchers are calling for more attention to a different type of temperature measurement known as the wet bulb globe temperature. It tracks temperature, humidity, and sunlight, and improves upon the heat index standard.

Umair Irfan, senior correspondent at Vox, joins SciFri’s Kathleen Davis to talk about measuring temperatures and protecting yourself from extreme heat. Plus, they discuss other stories from the week in science, including advances in tornado prediction, a delay in a return flight from the International Space Station, and a newly-described horned dinosaur that once roamed the US.
