Another next-gen battery upgrade has been reported Zinc-iodine batteries are now more stable The tech promises a more sustainable lithium-ion replacement With so many modern-day devices dependent on rechargeable lithium-ion batteries, scientists are hard at work trying to figure out ways of improving the tech — and a team from the Korea Research Institute of Chemical Technology (KRICT) has just announced a significant breakthrough. As reported by The Korea Times , the KRICT researchers have succeeded in boosting the power delivery capacity of lithium-ion battery chemistry by adding a small amount of a material called graphitic carbon nitride to the cathode end of the battery. When a battery is charging, the lithium ions get pushed out of the cathode, through an electrolyte material, to the anode at the other end. When the battery is in use, the ions flow back in the other direction. One potentia...

AWS deal with Nvidia adds 2 million Blackwell Ultra, Rubin, and Rubin Ultra GPUs, on top of more than 1 million committed in March 2026 Totals more than 3 million Nvidia GPUs due before 2029, a ~1.9x multiple for each of Amazon's roughly 1.58 million employees Nvidia's CFO has said deliveries start this quarter, not in 2027, but neither company says what it counts as a GPU or what the deal costs Amazon ended 2025 with about 1.58 million full- and part-time employees , most in fulfillment centers and delivery operations, with a much smaller share working in its AWS data center division (estimated at around 246,000). By mid-2028, Amazon Web Services expects to have taken delivery of roughly twice that many new Nvidia GPUs, based on a recent deal it made with Nvidia. The latest deal was announced on August 26 , the same afternoon Nvidia reported quarterly earnings, and will see AWS plan to d...

So-called signal sharing between Microsoft and Google uncovered the RedVDS marketplace was behind large-scale cyber fraud RedVDS sold access to virtual machines running unlicensed software from which cybercriminals launched scams and directed attacks Threat data was shared securely via the Global Signal Exchange (GSE), a non-profit organization A major cybercrime marketplace has been taken out of action thanks to cooperation between Microsoft and Google via a secure threat data sharing platform. Known as the Global Signal Exchange, the collaboration led to the take-down of the RedVDS, an online cybercrime mall supplying virtual machines for launching phishing, business email compromise attacks, and more. The marketplace – which provided quickly-deleted and therefore virtually untraceable VMs – was meticulously monitored by Microsoft’s security team, Digital Crimes Unit, with both Microsoft and Go...

Today's best smartwatches are ultra-capable, feature-packed powerhouses. But is it just me, or are they all starting to feel kinda samey? Casio recently made headlines with its delightfully retro F-B100W , which takes your classic, rubbery, blocky Casio watch and adds in step-counting features. That sent me off on a hunt for other smartwatches and fitness trackers that do something a bit different, and I was not disappointed with the results. I've rounded up my favorites below. There's the new-out Huawei Watch D3 , which looks like your standard, modern smartwatch, but has a secret, in-built blood pressure cuff. For those who prefer a traditional watch aesthetic, there are the Garmin Instinct Crossover and Withings Scanwatch 2 , both of which have smartwatch features but also mechanical hands. Neither is especially new, but both have maintained popularity by their seamless blending ...

Rune wants unused solar electricity powering GPUs instead of going to waste RELIC connects computing equipment directly to functioning solar generation sites The system operates without grid connections or conventional data center construction A San Francisco company named Rune has introduced a modular compute unit built to operate directly on unused solar power. Called RELIC, the equipment attaches to functioning solar installations without needing any connection to the electrical grid or new construction work. The launch came alongside a $40 million Series A financing round for Rune, lifting the firm's overall capital raised to $53.5 million total. Skipping the grid bottleneck Solar facilities routinely waste as much as 20% of the electricity they generate, adding up to more than 50 TWh yearly nationwide. RELIC pulls that idle current straight from the source, avoiding metering charges, uti...
