AI extends EV battery life by 23 percent, study says
A study finds that using artificial intelligence to control current during fast charging can extend electric vehicle battery life by up to 23 percent. Researchers at Sweden’s Chalmers University of Technology applied reinforcement learning to a battery management system to adjust current and voltage in real time based on battery condition, reducing stress as the battery ages. The results are based on simulations, and commercial use will depend on reproducing performance in real vehicles.

Ultraminiature optical chip smaller than a grain of salt aims to ease quantum computing, data centre bottlenecks
An ultraminiature optical chip has emerged that could sharply reduce the burden of laser control, long seen as a key obstacle to scaling quantum computers. The chip, about 1 square millimetre in size, rapidly redirects a small number of laser beams to many target points. It can scan about 68.6 million light spots per second, more than 50 times faster than micromirror-based beam scanners. The technology remains at the experimental stage.

Foundry chip market shifts from shrinking nodes to packaging as stacking and chiplets become battleground
The semiconductor industry is shifting its technology race from shrinking process nodes to packaging as scaling approaches physical limits. Companies are increasingly relying on 2.5D and 3D stacking and chiplets to meet performance, power and bandwidth demands, driving changes across the value chain that includes IP, libraries and EDA tools. Memory makers SK hynix and Samsung Electronics are advancing their packaging technologies. Intel has also demonstrated GaN-on-silicon chiplet technology and integration with silicon digital control circuits.
