Hashtag Trending May 17 – Texas shuts down power plants, AI sees racing in X-rays; Keyless unlock in Tesla hack

Texas shuts down power plants before hot weather hits, AI can tell race and nobody knows how, and a security researcher defeats Tesla’s keyless entry feature.

This is all the trending tech news right now, welcome to Hashtag Trending. It’s Tuesday, May 17th and I’m your host Tom Lee.

In the face of abnormally hot weather, Texas is warning its residents to conserve electricity as the state shuts down six power plants. The stations generate about 2,900 megawatts of electricity, capable of supplying electricity to 600,000 homes. Brad Jones, CEO of the Texas Electrical Reliability Council, said electricity demand would rise because of air conditioning, but he didn’t say why power plants would be turned off during a time of need. The NBC report described the power grid as still vulnerable after a winter storm caused blackouts that left millions in the dark last year.

For any human being, black and white photographs of a patient’s chest cavity should not indicate its characteristics besides his disease. But the researchers found that an AI trained to read X-rays and CT scans can also guess a patient’s race with up to 90% accuracy. However, researchers do not know what parameters the AI ​​uses to reach its conclusions. The ability of this program has baffled the international team of researchers, which includes scientists from the Massachusetts Institute of Technology and Harvard University. Even when presenting X-ray images to patients of similar age and size, the AI ​​was still able to distinguish between black and white patients. As researchers continue to search for a definitive answer, they suspect that melanin, the pigment that determines skin color, may be a contributing factor.

A security researcher has discovered a way to bypass the keyless unlocking feature on Tesla Model 3 and Y cars, allowing a thief to drive the car without a key. According to Bloomberg, the researcher was able to trick the car into believing the owner was nearby by manipulating the signal between the car, the key and the mobile device. Even more alarming, the researcher said the hack isn’t just about Tesla. The good news is that the hack does not appear to have been maliciously abused. To correct this vulnerability, Tesla needs to change its hardware and rework the keyless entry system. So far, the company does not consider the matter to be too risky.

Wondering if you have a loose screw? This new smart self-powered screw will tell you. The new screw, called the Smart Screw Connection, has an IoT sensor attached to the washer to let engineers know if it needs to be screwed around. An IUD uses a thin film of a photoresist material to measure mechanical strength. This is not just for convenience; Building inspectors can also add the gauge to their checklist when ensuring building safety. The downside, of course, is that each screw needs a power source to keep working, but researchers are looking to harvest energy to make the screws self-operating.
