- Magnetic avalanche triggered by quantum effects: 'Barkhausen noise' detected for first time
Iron screws and other so-called ferromagnetic materials are made up of atoms with electrons that act like little magnets. Normally, the orientations of the magnets are aligned within one region of the material but are not aligned from one region to the next. Think of packs of tourists in Times Square pointing to different billboards all around them. But when a magnetic field is applied, the orientations of the magnets, or spins, in the different regions line up and the material becomes fully magnetized. This would be like the packs of tourists all turning to point at the same sign.
- Plasma fusion: Adding just enough fuel to the fire
How much fuel can we add to the fire while still maintaining control? Metaphorically speaking, that's the question one team at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) has been asking themselves lately.

- Large language models use a surprisingly simple mechanism to retrieve some stored knowledge
Boston MA (SPX) Mar 27, 2024 Large language models, such as those that power popular artificial intelligence chatbots like ChatGPT, are incredibly complex. Even though these models are being used as tools in many areas, such as customer support, code generation, and language translation, scientists still don't fully grasp how they work. In an effort to better understand what is going on under the hood, researchers at
