Statistician Aaron Schein and Chris Wolfram, PhD student in Computer Science, use LLMs to extract information from the Babylonian Astronomical Diaries, verifying the LLM’s output with a Bayesian Model that knows the correct positions of the Moon, planets, and stars in the ancient night sky.


The cosmic microwave background, explained

October 27, 2026

The clear, dry conditions in regions like the South Pole and the Atacama Desert minimize interference from water molecules in the Earth’s atmosphere, allowing telescopes to take incredibly precise readings of the cosmic microwave background.

The cosmic microwave background is the faint residual light from the very beginnings of the universe. It’s often referred to as the afterglow of the Big Bang.

At over 13 billion years old, it is the oldest light in the universe—which makes it a tantalizing object of study for scientists seeking clues about our origins.


Quantum calculations reveal how quantum defects lose energy

October 27, 2026

Researchers in Galli Group at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) have built a computational framework that captures the full optical cycle of such spin defects, including the prediction of internal conversion

A first-principles framework from UChicago PME researchers sheds light on the utility of spin defects as qubits and could help design materials for energy conversion and storage.


Muon g-2 experiment places new constraints on a forbidden property of muons

October 27, 2026

Argonne is a collaborator on the Muon g-2 experiment, which is led by Fermilab. The collaboration has for the first time directly measured the electric dipole moment of the muon, a heavy cousin of the electron.

Argonne plays important role in the world’s most sensitive direct search for a muon electric dipole moment.


Uncovering long coherence times in the nitrogen vacancy centers of hexagonal diamonds

October 27, 2026

Nitrogen-vacancy (NV) centers in cubic diamonds.

Nitrogen-vacancy (NV) centers in cubic diamonds — a type of defect where a nitrogen atom substitutes a carbon atom neighboring a lattice vacancy — have commonly been studied for applications in quantum sensing and computing.

Old thermostat with words

UChicago geophysical scientists suggest that the way Earth’s “thermostat” works may have changed during the Pangea era.


Vietnamese professor cracks 55-year-old math puzzle, inspired by juggling

A Vietnamese mathematician and his German colleague have helped resolve a 55-year-old mathematical conjecture, using randomness and techniques inspired by juggling to tackle the problem.


Scientists simulated the Milky Way’s first billion years: and found a very different galaxy

October 19, 2026

A concept art for the start for the first billion years of the universe.

New simulations trace the Milky Way back to a turbulent network of thousands of small galaxies in the early universe.


Pham Tuan Huy and the story of solving a nearly half-century-old problem.

Pham Tuan Huy, a young Vietnamese mathematician, and his colleagues have solved a problem that has existed in the mathematical community for nearly 50 years.


The Milky Way is one galaxy — but it used to be thousands, new simulations reveal

October 19, 2026

A supercomputer simulation of how the Milky Way appeared at the dawn of the universe. Purple colors show hot gas, white shows UV radiation from young stars, and yellow shows glowing oxygen atoms.

A new supercomputer simulation traces how thousands of small galaxies eventually became the Milky Way.

MSCAPP students Sinan Grehan and Wendy Wang spent the summer at the Energy Policy Institute at UChicago using data, econometrics, and environmental research to investigate policy questions that range from wetlands regulation to the hidden costs of climate change.


New simulation projects what the Milky Way looked like at ‘cosmic dawn’

October 12, 2026

Using powerful supercomputers, scientists created an extensive simulation of what the Milky Way could have looked like long ago—a chaotic progression of hot gas cooling, condensing into stars, and exploding, over and over again. Purple indicates hot gas

Most complex rendering of its kind provides insight into early days of our home galaxy.
