Last summer, California highway police pulled over pop star Justin Bieber as he sped through Los Angeles in an attempt to shake the paparazzi. He was driving a hybrid electric car—not just any hybrid, mind you, but a chrome-plated Fisker Karma, a US $100 000 plug-in hybrid sports sedan he’d received as an 18th-birthday gift from his manager, Scooter Braun, and fellow singer Usher. During an on-camera surprise presentation, Braun remarked, “We wanted to make sure, since you love cars, that when you are on the road you are always looking environmentally friendly, and we decided to get you a car that would make you stand out a little bit.” Mission accomplished.

Fires at recycling sorting facilities, ignited by combustible materials in the waste stream, can cause millions of dollars in damage, injuring workers and first responders and contaminating the air.

Detecting the blazes early is key to preventing them from getting out of control.

Mayo Clinic researchers have developed an artificial-intelligence algorithm that can detect weak heart-pump functioning from a single-lead electrocardiogram (ECG) on the Apple Watch. Early results indicate that the ECG is as accurate as a medically ordered treadmill stress test but could be performed anywhere, the researchers say.

The single-lead AI algorithm was adapted from an existing algorithm that works by analyzing ventricular pumping data from a 12-lead ECG already in clinical use under an Emergency Use Authorization from the U.S. Food and Drug Administration (FDA).
