Peter Alan Fedders, a professor emeritus of physics in Arts & Sciences at Washington University in St. Louis, died Feb. 22, 2024, in La Jolla, Calif. He was 85. Fedders was an expert in condensed-matter physics who made significant contributions to the theory of nuclear magnetic resonance.

Researchers in Arts & Sciences discovered that a common mineral called goethite, found in red soils all over the Earth, tends to naturally trap trace metals over time, locking them out of circulation.

Eighteen years after NASA’s Stardust mission returned to Earth with the first samples from a known comet, the true nature of that icy object is coming into focus, according to physicist Ryan Ogliore in Arts & Sciences.

Sleep helps restore the brain’s operating system to a critical state, according to new findings from biology and physics researchers in Arts & Sciences.

Peter R. Phillips, a professor emeritus of physics in Arts & Sciences, died Friday, Dec. 1, 2023, in St. Louis. He was 92 years old.

Research from Washington University in St. Louis shows that variations in pyrite sulfur isotopes may not represent global processes. A new microanalysis approach helps to separate out signals that reveal the relative influence of microbes and that of local climate.

Research led by Bronwen Konecky in Arts & Sciences takes an important step toward reconstructing a global history of water over the last 2,000 years.

Physicist Mikhail Tikhonov, in Arts & Sciences, developed a new statistical model that could help design microbial communities for performing certain functions.

A team of researchers including Kater Murch, professor of physics in Arts & Sciences, has found a shortcut to establishing a baffling phenomenon of quantum physics.

Physicists in Arts & Sciences are gaining quantum insights from imperfect crystals. The research supported by the Center for Quantum Leaps advances the field of quantum simulation using an atomic-level quantum system.
