alternative_right shares a report from ScienceAlert: A study published in PLOS One in 2021 by researchers from Durham University in the UK showed that with 10 weeks of training, both blind and sighted people could learn to echolocate using verbal clicks. While the technique is already used by a number of people with impaired vision -- sometimes using the taps of a cane instead of clicks made by their mouth -- those findings suggest that many of us can learn the necessary techniques. Some of the same researchers who made that discovery are part of the team behind a follow-up study published in Cerebral Cortex, looking at how the 10 weeks of training that the 26 participants went through actually changed the physical structure of their brains. Specifically, the team analyzed brain scans of the V1 (the primary visual cortex, processing visuals), and the A1 (the primary auditory cortex, processing sounds). Strikingly, the scans showed that the V1s of both blind and sighted people had developed sensitivity to sound echoes during echolocation training.

"The Norwegian certification agency DNV has certified the commercial wave-driven power generator Corpower C4 for regular use," writes Longtime Slashdot reader Qbertino. "German news site heise.de has a detailed write-up. See a CGI video of the power station and its internals, as well as the company's website [at their respective links]." From the report (translated to English): According to the manufacturer Corpower Ocean, it is the first DNV prototype certificate for a wave energy converter. The certificate confirms that Corpower's technology meets DNV's requirements for structural strength, reliability, and safety, Corpower Ocean announced. The certification process began in the design phase and lasted seven years. DNV oversaw the process from concept development through design, manufacturing, and assembly, to dry-running tests and subsequent operation. This is an important step, said Patrik Moller, CEO and one of the founders of Corpower Ocean. With the certification, wave energy is no longer just a promising technology, but a proven and financially viable one. This opens up new opportunities for project financing, insurance, and investments in commercial applications. The Corpower C4 wave power plant looks like a normal buoy: It consists of a 19-meter-long floating body with a diameter of 9 meters and a weight of approximately 11 tons. The system is anchored to the seabed. A mechanism inside the buoy converts its up-and-down movements in the waves into a rotary motion. This, in turn, drives a generator that produces electricity. The report notes that the company is "planning the first two industrial-scale wave energy farms off the coasts of Portugal and Scotland," which are scheduled to begin operating sometime between 2027 and 2029.

An anonymous reader quotes a report from Engadget: You'll now be able to use selfie videos to log into your Google account. It has long been possible to log into Google using your face, via your phone's face unlock or if your passkey login uses biometrics for verification. This is yet another option to get into your account using your face to authenticate your identity, which could be especially useful if you don't have access to the phone or computer you typically use or if you got locked out of your account and none of the other log-in options are working. [...] Google will ask you to turn your head in certain ways during the verification and every time you use the option to log in. The company says it's to fend off impersonation attempts, such as deepfake videos, and prove you're currently in front of the camera. It will, of course, have to save your selfie video and use it for comparison for future logins.The company says it will encrypt your video and only use to help you sign in, but if you ever change your mind, you can delete it from your Google account. It's worth noting the option is currently unavailable for Workspace accounts, child accounts and those enrolled in Google's Advanced Protection Program. You can set it up and give it a try at g.co/signin-selfie.
