The Download: protecting farmworkers from heat, and AI’s Nobel Prize

On July 21, 2024, temperatures soared in many parts of the world, breaking the record for the hottest day ever recorded on the planet.

The following day—July 22—the record was broken again.

But even as the heat index rises each summer, the people working outdoors to pick fruits, vegetables, and flowers have to keep laboring.

The consequences can be severe, leading to illnesses such as heat exhaustion, heatstroke and even acute kidney injury.

Now, researchers are developing an innovative sensor that tracks multiple vital signs with a goal of anticipating when a worker is at risk of developing heat illness and issuing an alert. If widely adopted and consistently used, it could represent a way to make workers safer on farms even without significant heat protections. Read the full story.
