Artificial Intelligence is really good at predicting heart attacks

Better than the guidelines doctors use, in fact. That's the conclusion of a new study written up in Science magazine. Here's how they tested it: A UK epidemiologist and his colleagues tested four machine-learning algorithms against the doctors' guidelines, to see how well they could predict which patients would have heart troubles based on 2005 medical records. Sure enough, the artificial intelligence programs did a better job of predicting who actually had heart attacks and other problems within the next 10 years.

What it means: If computers can teach themselves, they may be able to account for a lot of random factors with people's health, more than doctors can keep track of themselves. If these programs had actually been used, the study's authors said, 355 people's lives could have been saved.

Yes, but: Given how much trouble doctors have had with electronic medical records, are they really going to be enthusiastic about adding even more technology to their practices?

There was a time when a months-long sports absence would have silenced athletes, leaving them without a platform to reach fans or make their voices heard.

Why it matters: But now that athletes boast massive social media followings and no longer need live game broadcasts or media outlets to reach millions, they're speaking out en masse amid protests over the death of George Floyd and other police-related killings of black people — delivering messages of frustration and unity, despite their leagues not currently operating.

The ways Americans capture and share records of racist violence and police misconduct keep changing, but the pain of the underlying injustices they chronicle remains a stubborn constant.

Driving the news: After George Floyd's death at the hands of Minneapolis police sparked wide protests, Minnesota Gov. Tim Walz said, “Thank God a young person had a camera to video it."
