The macOS 15 Sequoia update will inevitably be known as "the AI one" in retrospect, introducing, as it does, the first wave of "Apple Intelligence" features.

That's funny because none of that stuff is actually ready for the 15.0 release that's coming out today. A lot of it is coming "later this fall" in the 15.1 update, which Apple has been testing entirely separately from the 15.0 betas for weeks now. Some of it won't be ready until after that—rumors say image generation won't be ready until the end of the year—but in any case, none of it is ready for public consumption yet.

But the AI-free 15.0 release does give us a chance to evaluate all of the non-AI additions to macOS this year. Apple Intelligence is sucking up a lot of the media oxygen, but in most other ways, this is a typical 2020s-era macOS release, with one or two headliners, several quality-of-life tweaks, and some sparsely documented under-the-hood stuff that will subtly change how you experience the operating system.

One key challenge in medical imaging is to look past skin and other tissue that are opaque to see internal organs and structures. This is the reason we need things like ultrasonography, magnetic resonance, or X-rays. There are chemical clearing agents that can make tissue transparent, like acrylamide or tetrahydrofuran, but they are almost never used in living organisms because they’re either highly toxic or can dissolve away essential biomolecules.

But now, a team of Stanford University scientists has finally found an agent that can reversibly make skin transparent without damaging it. This agent was tartrazine, a popular yellow-orange food dye called FD&C Yellow 5 that is notably used for coloring Doritos.

Playing with light

We can’t see through the skin because it is a complex tissue comprising aqueous-based components such as cell interiors and other fluids, as well as protein and lipids. The refractive index is a value that indicates how much light slows down (on average, of course) while going through a material compared to going through a vacuum. The refractive index of those aqueous components is low, while the refractive index of the proteins and lipids is high. As a result, light traveling through skin constantly bends as it endlessly crosses the boundary between high and low refractive index materials.

DirecTV and Disney agreed to a new distribution contract on Saturday, ending a two-week blackout during which DirecTV subscribers lost access to ABC, ESPN, and other Disney-owned channels. A joint announcement said the companies reached an agreement in principle and that "Disney's full linear suite of networks has been restored to DirecTV, DirecTV Stream and U-verse customers while both parties work to finalize a new, multi-year contract."

While Disney previously accused DirecTV of "undervaluing" its content, DirecTV said during the blackout that it was seeking flexibility to sell slimmed-down channel packages that don't force customers to buy channels they don't want. The joint announcement of the resolution said the new deal "provides greater choice, value, and flexibility to [the companies'] mutual customers."

The deal includes ABC and ESPN networks, Disney-branded channels, Freeform, FX networks, and National Geographic channels. DirecTV will be able to "offer multiple genre-specific options—sports, entertainment, kids & family—inclusive of Disney's linear networks along with Disney+, Hulu and ESPN+," the companies said.

On Thursday, Oracle co-founder Larry Ellison shared his vision for an AI-powered surveillance future during a company financial meeting, reports Business Insider. During an investor Q&A, Ellison described a world where artificial intelligence systems would constantly monitor citizens through an extensive network of cameras and drones, stating this would ensure both police and citizens don't break the law.

Ellison, who briefly became the world's second-wealthiest person last week when his net worth surpassed Jeff Bezos' for a short time, outlined a scenario where AI models would analyze footage from security cameras, police body cams, doorbell cameras, and vehicle dash cams.

"Citizens will be on their best behavior because we are constantly recording and reporting everything that's going on," Ellison said, describing what he sees as the benefits from automated oversight from AI and automated alerts for when crime takes place. "We're going to have supervision," he continued. "Every police officer is going to be supervised at all times, and if there's a problem, AI will report the problem and report it to the appropriate person."
