For years, Qualcomm has been making Snapdragon chips for Windows PCs, and for years, those chips' performance have failed to dislodge Intel's or AMD's chips to any significant degree. Its latest Snapdragon 8cx Gen 3 (and the closely related Microsoft SQ3) appears in just two consumer PCs, the cumbersomely named Microsoft Surface Pro 9 with 5G and Lenovo's ThinkPad X13s Gen 1.

But that may be changing. Nearly three years ago, Qualcomm bought a company called Nuvia for $1.4 billion. Nuvia was mainly working on server processors, but the company's founders and many of its employees had also been involved in developing the A- and M-series Apple Silicon processors that have all enabled the iPhone, iPad, and Mac to achieve their enviable blend of performance and battery life. Today, Qualcomm is formally announcing the fruit of the Nuvia acquisition: the Qualcomm Snapdragon X Elite is a 12-core, 4 nm chip that will compete directly with Intel's Core processors and AMD Ryzen chips in PCs—and, less directly, Apple's M2 and M3-series processors for Macs.

Qualcomm says the Snapdragon X Elite will begin arriving in PCs starting in mid-2024. The company has also announced a new Snapdragon SoC for smartphones, the Snapdragon 8 Gen 3.

There are many different species of kingfisher, and those that eat fish hunt by repeatedly diving head-first into the water when they spot tasty prey without suffering brain injuries like concussions. It turns out that diving kingfishers have several modified genes associated with diet and brain structure, according to a new paper published in the journal Communications Biology—notably mutations in genes related to the tau proteins that help stabilize neuron structure, although they can be harmful if too many build up.

“I learned a lot about tau proteins when I was the concussion manager of my son’s hockey team,” said co-author Shannon Hackett, associate curator of birds at the Field Museum. “I started to wonder, why don’t kingfishers die because their brains turn to mush? There’s gotta be something they're doing that protects them from the negative influences of repeatedly landing on their heads on the water’s surface.”

It's not the first time scientists have pondered this question, not just for kingfishers, but for other birds like gannets and woodpeckers. For instance, physicists at Virginia Tech studied diving gannets back in 2014 (publishing their conclusions in 2016), which fold their wings back as they dive, hitting the water with their whole body to snag underwater prey. From a physics standpoint, we're talking about an elastic body hitting the surface of water as fast as 55 MPH. The stress of moving from the medium of air to the much denser medium of water exerts a huge force on the bird's body, with an impact akin to tornadoes hitting the water. Yet despite the stress on their bodies, gannets (like the kingfisher) manage the feat again and again without injury, especially concussions.

  Google says Samsung Wallet is spying on you! (It isn't.) [credit: User 7072490759456883590 ]

Most Android users have probably never seen Google Play Protect in action. The malware-scanning service is built into every Android device and is supposed to flag malware that users have installed. Recently it flagged some popular apps that are very much not malware: Samsung Wallet and Samsung Messages.

As spotted by 9to5Google, Samsung users have been getting hit with Play Protect warnings since earlier this month. Users on the Google Support forum have posted screenshots of Play Protect flagging the Samsung system apps, and even Samsung responded to the issue, explaining (in Korean) how to fix any damage caused by the bug. Samsung says (through translation) the issue was caused by "a temporary failure of the Google server" and should now be fixed.

Samsung Wallet and Samsung Messages both come bundled with most Samsung phones as system apps, so they have a wide install base. When Play Protect flags an app as harmful, it pops up a message suggesting users remove the app, but since these are both system apps, users can only disable them.

A search engine that uses facial recognition to help people scan billions of images to find their photos strewn across the Internet has officially banned searches of minors, The New York Times reported. The move comes after years of criticism from privacy experts, media outlets, and regulators, warning that tech like PimEyes could be abused to stalk children online.

PimEyes CEO Giorgi Gobronidze told The Times that in addition to setting a "no harm policy," the company has also implemented new AI age-detection technology to detect and block searches of minors. This update is due to privacy concerns that "images of children might be used by [some] individuals with a twisted moral compass and values, such as pedophiles, child predators," Gobronidze said. Critics had long warned that PimEyes' tech made it easy to upload a photo of any child and quickly find other photos or discover their name and address.

By design, PimEyes is supposed to make it easy for people to figure out where their own photos have been posted online, but PimEyes has no way to stop people from searching for photos of other people, The Times reported. The platform's "data security unit" has monitored suspicious activity in the past by flagging any upload of a child's photo or detecting when male users repeatedly search for photos of women, the BBC reported. Gobronidze confirmed to The Times that out of 118,000 searches per day of PimEyes' database of 3 billion images, the company has detected and banned more than 200 accounts conducting "inappropriate searches of children’s faces."
