NASA’s new AI model can predict when a solar storm may strike

NASA and IBM have released a new open-source machine learning model to help scientists better understand and predict the physics and weather patterns of the sun. Surya, trained on over a decade’s worth of NASA solar data, should help give scientists an early warning when a dangerous solar flare is likely to hit Earth.

Solar storms occur when the sun erupts energy and particles into space. They can produce solar flares and slower-moving coronal mass ejections that can disrupt radio signals, flip computer bits onboard satellites, and endanger astronauts with bursts of radiation. 

While there’s no way to prevent these sorts of effects, being able to predict when a large solar flare will occur could let people work around them. Read the full story.

Why recycling isn’t enough to address the plastic problem

I remember using a princess toothbrush when I was little. The handle was purple, teal, and sparkly. Like most of the other pieces of plastic that have ever been made, it’s probably still out there somewhere, languishing in a landfill. (I just hope it’s not in the ocean.)

I’ve been thinking about that toothbrush again this week after UN talks about a plastic treaty broke down on Friday. Nations had gotten together to try and write a binding treaty to address plastic waste, but negotiators left without a deal.

Plastic is widely recognized as a huge source of environmental pollution—again, I’m wondering where that toothbrush is—but the material is also a contributor to climate change. Let’s dig into why talks fell apart and how we might address emissions from plastic.

Quote of the day

“It jumbles my freaking nugget that people can look at a squat and not understand how it’s supposed to look. You don’t need AI to do that.”

—Andrew Hiller, a CrossFit coach and critic of poorly-executed squats, tells the New York Times why doing away with vigilant human judges for the popular fitness race Hyrox would be a mistake.
