Hong Wang, Member (2019–21) in the School of Mathematics, and her colleague Joshua Zahl have proven the three-dimensional Kakeya conjecture, a problem that has, until now, “eluded some of the greatest living mathematicians.” Their work has built on that of other IAS scholars, including Jean Bourgain, Professor (1994–2018) in the School, and Terence Tao, Member (2005, 2023) in the School.

Alessio Figalli, Member in the School of Mathematics, investigates optimal transport, a field with deep theoretical roots and far-reaching applications, including to machine learning. Figalli recently sat down with frequent Director's Visitor Siobhan Roberts for a New York Times interview about his work, which also touched on the importance of free thinking in research.

Drawing on her perspective as a historian of medieval religion and society and her specialization in medieval France, Anne Elisabeth Lester, Visitor in the School of Historical Studies, recounts the devastating fire that engulfed Notre-Dame Cathedral in Paris in April 2019, and the subsequent efforts to rebuild it, for the American Historical Association's newsmagazine Perspectives on History.

Alondra Nelson, Harold F. Linder Professor in the School of Social Science, spoke with MIT Science Policy Review about the role of scientists and the broader public in shaping policy. She discussed the various ways in which scientists can participate in policymaking and the importance of and challenges that surround public access to science.

Why are some stars brighter than others? Why are some redder or bluer? A plot from a recent research paper by Hsiang-Chih Hwang, Member in the School of Natural Sciences, which addresses this question, has been selected as the Gaia Space Telescope's Image of the Week.

At a workshop held at IAS in March, Sebastian Mizera, Member in the School of Natural Sciences, "met with fellow S-matrix enthusiasts. Inspired by recent progress, they continue to seek more universal rules that govern all S-matrices. [...] They focus on observations, striving to discover truths that will endure even when the shape of future theories remains uncertain."

Jim Simons, former IAS Member (1972), Trustee (2001–18), and Board Vice Chair (2010–18), "led a life driven by curiosity." A tribute posted on the Simons Foundation website honors his achievements in mathematics, business, and philanthropy.

"In 1940, André Weil [Faculty (1958–76) and Emeritus (1976–98) in the School of Mathematics] wrote a letter to his sister, Simone, outlining his vision for translating between three distinct areas of mathematics. Eighty years later, it still animates many of the most exciting developments in the field."

In an article for Quanta, Isabel Garcia Garcia, past Member in the School of Natural Sciences (2022–23), discusses the latent possibilities of LISA, the first dedicated space-based gravitational wave observatory, currently scheduled to launch in the 2030s.

A research team led by Adam Burrows, Member in the School of Natural Sciences, has created the largest collection yet of state-of-the-art, three-dimensional core-collapse supernova simulations.
