Google to build data centre from 2,000 discarded Pixel phones in low-cost server test
Google has begun testing a low-cost data centre built from retired Pixel smartphones, aiming to cut costs and electronic waste by turning discarded devices into computing resources. Researchers stripped phones to mainboards and replaced Android with a Linux-based environment to run orchestration platforms such as Kubernetes. Tests showed clusters of dozens of phones could support applications used by students. The team is also pursuing a 2,000-phone facility designed to support about 100 classes.

Nvidia unveils Ising open-source quantum AI models to tackle errors
Nvidia has unveiled an open-source artificial intelligence model family called Ising to calibrate quantum computers and correct errors. The company aims to use AI to address key bottlenecks that have held back commercial quantum computing. It chose decoding and calibration as initial applications. Ising includes an error-correction decoding model and a calibration model that automates ongoing tuning work. Nvidia also released guides, training data and Nvidia NIM microservices.

LG Energy Solution points to commercial viability of sulfur-based batteries
LG Energy Solution said it developed a high-capacity battery using sulfur as a cathode material by applying all-solid-state battery technology. The company said the approach blocks polysulfide dissolution seen in liquid electrolytes, securing about 1,500 mAh/g capacity and stable cycle life. It said the performance was demonstrated in both coin cells and pouch-type cells. The work was conducted with a University of Chicago research team and published in Nature Communications.
