In quantum mechanics, the geometry of quantum states has emerged as a powerful framework for understanding phenomena ranging from electrical conductivity to superconductivity. One research direction aims to extend these geometric concepts to non-Hermitian quantum mechanics—where

The Universitat Autònoma de Barcelona (UAB) and the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) have developed a new generation of wireless piezoelectric microdevices capable of electrically stimulating living cells at an individual level. The study, recently publis

Next-generation batteries that use new electrolyte materials could achieve far higher energy density than today's lithium-ion batteries, without many of the safety concerns. But advanced batteries, such as those that use solid or almost-solid electrolytes, have been plagued by th

A newly developed material can control and "program" heat, allowing it to direct thermal radiation, switch modes, and remember its settings without continuous power. The innovation could lead to smarter infrared sensors, better energy technologies, and memory devices that use lig

Advanced magnetic memory and spintronic devices rely on the ability to control magnetic states using electricity. Today, such technologies work by manipulating relatively simple magnetic structures found in ferromagnets, where all the magnetic moments point the same way. However,

Guardian analysis found the removals coincided with the Trump administration’s push to weaken efficiency rulesAs millions of Americans prepare for another brutal heatwave, it’s now harder to find information about ways to stay cool while saving energy and keeping utility costs down.At least 1,662 department of energy webpages offering guidance on protecting the electrical grid during heatwaves have gone dark as of 3 July, according to a Guardian analysis of a list of deleted URLs provi

I’ve been asked to put away the dog bed – and even my shower gel. Surely prospective buyers should know that I’ll take all my mess with me when I leaveTrying to sell a house is pretty much a once-a-decade event for me, so I shouldn’t be surprised that times have changed. When I sold my first flat in 2006, the norm was actively anti-tidy. Obviously you’d spirit away food waste and animal detritus, maybe you’d put a lid on your laundry basket, but the market was overheated; everything wa
