16-year-old Mexican student creates an acoustic fire extinguisher that uses sound waves to put out fires in seconds

She assembled a device with a 12-volt battery, a frequency generator, and a speaker that emits 30 pulses per second. That vibration pushes oxygen away from the flames, and the fire simply goes out in five to eight seconds.

This is very, very cool. It sounds like it's something that could eventually replace home fire extinguishers as the technology develops, but I'm curious if it could ever be applied in a bigger way for fire departments fighting house fires or even forest fires in some way. Maybe wineries out here in Napa will start placing speakers around their vines to help keep flames at bay one day.

🤖 As AI enters the operating room, reports arise of botched surgeries and misidentified body parts

The device had already been on the market for about three years. Until then, the U.S. Food and Drug Administration had received unconfirmed reports of seven instances in which the device malfunctioned and another report of a patient injury. Since AI was added to the device, the FDA has received unconfirmed reports of at least 100 malfunctions and adverse events.

Medical devices, including those used in surgeries and critical monitoring should never have AI because we know AI hallucinates and will always make avoidable mistakes. It may be useful for research and diagnosis (or secondary monitoring) where a human has time to review and confirm, but when someone’s life is on the line, we don’t need to add additional variables that might ignore critical information or take circuitous routes for no good reason, compounding the potential risk of human error that already exists—which AI is not reducing.
