The Nobel Prize in Chemistry was awarded on Wednesday to Moungi G. Bawendi, Louis E. Brus and Alexei I. Ekimov for being pioneers of the nanoworld. The new laureates discovered and developed quantum dots, semiconductors made of particles squeezed so small that their electrons barely have room to breathe. From a report: “For a long time, nobody thought you could ever actually make such small particles,” Johan Aqvist, the chair of the Academy’s Nobel committee for chemistry, said at the news conference announcing the 2023 laureates. Presenting the topic with five colorful flasks lined up in front of him, which he said contained quantum dots in a liquid solution, he said: “But this year’s laureates succeeded.”

Los Angeles is housing more people than ever, and building lots more low-income housing, yet it can’t keep pace with this ever-rising number of people who end up in cars, tents and shelters. “It’s a bucket with a hole in it, so we’ve got to do something … to fill that hole,” says Dana Vanderford, who helps lead the department’s Homelessness Prevention unit. With that goal, the pilot program is using artificial intelligence to predict who’s most likely to land on the streets, so the county can step in to offer help before that happens. From a report: The program tracks data from seven county agencies, including emergency room visits, crisis care for mental health, substance abuse disorder diagnosis, arrests and sign-ups for public benefits like food aid. Then, using machine learning, it comes up with a list of people considered most at-risk for losing their homes. Vanderford says these people aren’t part of any other prevention programs. “We have clients who have understandable mistrust of systems,” she says. They’ve “experienced generational trauma. Our clients are extremely unlikely to reach out for help.” Instead, 16 case managers divide up the lists and reach out to the people on them, sending letters and cold calling.

Apple rolled out a software update Wednesday to address an overheating issue that plagued some early buyers of the iPhone 15 Pro line. From a report: The update, called iOS 17.0.3, is available as an over-the-air fix in the software update section of the iPhone settings app. The release notes say the update “provides important bug fixes, security updates, and addresses an issue that may cause iPhone to run warmer than expected.” The update was also released for older iPhones as well as iPads. Some early iPhone 15 Pro owners reported that their iPhone could get hotter than normal. Apple on Saturday blamed bad code in apps including Uber, Instagram and the Asphalt 9 racing game, in addition to a bug in the device’s software. The company said the new device set-up could overwork the processor and lead to overheating.
