Infamous for their environmental persistence and potential links to health conditions, per- and polyfluoroalkyl substances (PFAS), often called forever chemicals, are being discovered in unexpected places, including beer. Researchers publishing in ACS’ Environmental Science & Technology tested beers brewed in different areas around the U.S. for these substances. They found that beers produced in parts…

Graphene just broke a fundamental law of physics

For several decades, a central puzzle in quantum physics has remained unsolved: Could electrons behave like a perfect, frictionless fluid with electrical properties described by a universal quantum number? This unique property of electrons has been extremely difficult to detect in any material so far because of the presence of atomic defects, impurities, and imperfections…

How do AI models generate videos?

But you don’t want any image—you want the image you specified, typically with a text prompt. And so the diffusion model is paired with a second model—such as a large language model (LLM) trained to match images with text descriptions—that guides each step of the cleanup process, pushing the diffusion model toward images that the…
