Researchers in Germany have unveiled the Metafiber, a breakthrough device that allows ultra-precise, rapid, and compact control of light focus directly within an optical fiber. Unlike traditional systems that rely on bulky moving parts, the Metafiber uses a tiny 3D nanoprinted hologram on a dual-core fiber to steer light by adjusting power between its cores. This enables seamless, continuous focus shifts over microns with excellent beam quality.

Deep beneath southern China, JUNO has launched one of the most ambitious neutrino experiments in history. With its massive 20,000-ton liquid scintillator detector now operational, it’s poised to answer one of particle physics’ greatest mysteries: the true ordering of neutrino masses. Built over more than a decade and involving hundreds of scientists worldwide, JUNO not only promises to resolve questions about the building blocks of matter but also to open entirely new frontiers—from exploring signals of supernovae to hunting for evidence of exotic physics.

The U.S. National Science Foundation has announced two new Dear Colleague Letters (DCL) and one program solicitation that implement key elements of the Trump administration’s executive order, “Advancing Artificial Intelligence Education for American Youth.” The new opportunities will take decisive steps to expand resources for K-12 AI education, enhance teacher training and harness AI tools and services to improve science, technology, engineering and mathematics (STEM) teaching and learning.

“For decades, NSF has invested in research projects designed to transform STEM teaching and learning to meet emerging needs like AI. Integrating AI into education systems helps to prepare both young and adult learners to contribute to an AI-driven society,” said NSF Assistant Director for STEM Education James L. Moore III. “With these new funding mechanisms, NSF will fast-track its efforts to provide early exposure to AI, scale AI curricula, expand services that support the use of AI in education, advance teacher professional development and improve knowledge sharing in AI education to help sustain the nation’s leadership in technological innovation.”

Dear Colleague Letters

The Expanding K-12 Resources for AI Education DCL seeks to build upon NSF’s extensive investments in fundamental research, technology transition and education related to the science and application of AI. Existing awardees with K-12 AI or computer science education experience are invited to submit supplemental funding proposals to refine, scale, and/or implement established K-12 AI-related activities.
