At issue is the question of whether the best place to build data centres for artificial intelligence is not on Earth—but in ...

Twisting atomically thin magnetic layers does more than reshape their electronics—it can create giant, topological magnetic textures. In chromium triiodide, researchers observed skyrmion-like patterns ...
