The Department of Energy's Pacific Northwest National Laboratory (PNNL) has officially begun its first utility-grade battery tests at the new Grid Storage Launchpad (GSL), initiating a rigorous one-year testing regime." This milestone marks a significant leap in domestic energy research capabilities, raising the testing ceiling from previous limits of less than 10 kilowatts to a new capacity of 100 kilowatts." This tenfold increase allows researchers to validate technologies with the sophisticated controls and scale necessary for the modern electrical grid. "At GSL, researchers can test and validate batteries up to 100 kilowatts, unlocking insights into how grid-scale batteries can help support a reliable, affordable and secure electrical grid," said PNNL in a press release. The inaugural test centers on a vanadium flow battery developed by Invinity Energy Systems,…...

22+ min ago (641+ words) Home " Contributed Content " Rethinking Security as Access Control Moves to the Edge The convergence of physical and digital security is driving a shift toward software-driven, open-architecture edge computing. Access control has typically been treated as a physical domain problem " managing who can open which doors, using specialized systems largely isolated from broader enterprise IT. However, the boundary between physical and digital security is increasingly blurring. With that shift comes a need to revisit the architecture of access control infrastructure itself. The traditional model " centralized servers handling decision logic, with field devices acting primarily as passive endpoints " remains common. But it reflects an earlier design philosophy, one in which physical security systems were purpose-built and evolved slowly. That's changing. Increasingly, decisions are being pushed to the edge " to the access controllers that are physically present near points of entry. Controllers sit…...

26+ min ago (235+ words) The AirTag 2 will include a handful of new features that will improve tracking capabilities, according to a new report from Macworld. The site says that it was able to access an internal build of iOS 26, which includes references to multiple unreleased products. Here's what's supposedly coming: We've been hearing rumors about a new version of the "AirTag" for years now, and it's supposedly getting upgraded tracking with a new Ultra Wideband chip. The new chip will improve Precision Finding range, and it could also add these new tracking capabilities. So far, there have been no rumors of a redesign, so the "AirTag" 2 will presumably look like the original "AirTag". It will continue to feature a replaceable battery, though it could also get upgraded speakers that are harder to remove. The "AirTag" is apparently labeled "2025AirTag" in the "iOS 26" code, which suggests…...
