A diamond-based quantum sensor inserted into a living cell can provide previously unseen levels of detail about how life works and how diseases form. "Think of it as an EKG for a single cell—a way to capture everything happening inside at once, in real time," said University of Chicago Pritzker School of Molecular Engineering professor Aaron Esser-Kahn. "We routinely monitor vital signs in people—heart rate, breathing, temperature—but until now, there simply hasn't been an equivalent way to take a cell's vitals." https://phys.org/news/2026-08-method-sharpen-diamond-quantum-sensors.html Cell & Microbiology Tue, 04 Aug 2026 14:20:01 EDT news705065822 In mathematics and getting dressed, some processes are commutative, while others are noncommutative. Commutative means the order doesn't matter (3 + 2 is the same as 2 + 3, and it doesn't matter which sock goes on first).
