Although memory is subjective and colored by experience, a team of researchers, led by Weishun Zhong, Eric and Wendy Schmidt Member in Biology in the School of Natural Sciences, and Misha Tsodyks, C. V. Starr Professor in the School, have discovered that our brains share a universal mathematical structure for memory organization. Their findings bridge the disciplines of physics and neuroscience, revealing potential applications ranging from AI to memory disorder treatment.

Chris Hamilton, John N. Bahcall Fellow in the School of Natural Sciences (2021–26), describes how the Institute’s intense academic environment has helped him focus and accelerate his research, and the benefits of receiving rapid feedback from colleagues like Professor Emeritus Scott Tremaine.

Giovanni Maria Tomaselli, Member in the Institute for Advanced Study's School of Natural Sciences (2024–27), introduces the enigmatic substance of dark matter, which forms the focus of his current research and of lively discussions during Astro Coffee meetings.

Giovanni Maria Tomaselli, Member in the School of Natural Sciences, delves into the cosmic mystery of dark matter—the invisible substance that comprises 85 percent of the universe. He introduces three of the main candidates for dark matter's composition and discusses his own innovative insights into how such matter might interact with binary black hole pairs.

Why do collisionless plasmas like the solar wind, a constant stream of charged particles that flows away from the Sun, exhibit a universal "non-thermal tail"? Uddipan Banik, Member in the School of Natural Sciences, has proposed a fundamental, first-principles explanation for this phenomenon.

Motivated by the growing interest in using artificial intelligence for teaching purposes, IAS scholars from the Schools of Mathematics and Natural Sciences have conducted an innovative study to assess the correctness and helpfulness of large language models in STEM education. Their research yielded surprising results, including highlighting the importance of training models on conversations rather than textbooks.

Scholars from the School of Natural Sciences are leading investigations into the sources of gravitational wave signals, the unexpectedly high frequency of detections, and—extending beyond these direct questions—establishing innovative and unexpected connections between gravitational wave research and particle collider physics. These contributions are redefining our understanding of the field.

Sihao Cheng, Martin A. and Helen Chooljian Member in the Institute for Advanced Study’s School of Natural Sciences (2022–25), describes how he is mining a previously overlooked dataset in his ongoing search for a possible ninth planet in our solar system.

Meet Beatrix Muehlmann, Member in the School of Natural Sciences, who is curious about the origin and fate of the universe. In this Q&A, she details her efforts to describe gravity through the principles of quantum mechanics, her admiration for mathematical physicist Emmy Noether, and the joy of being a part of a group of scientists interested in fundamental questions.

Digvijay Wadekar, Member in the School of Natural Sciences (2021–24), reflects on the evolving nature of problem-solving in modern physics and how the Institute for Advanced Study supports both interdisciplinary collaboration and individual inquiry.
