The nature and spectrum of elementary excitations are defining features of a many-body system. Here, we use a Rydberg quantum simulator to demonstrate a form of spectroscopy, called quench spectroscopy, that probes these low-energy excitati...

The brain's response to injury includes the activation of intrinsic microglia and the influx of leukocytes, collectively constituting neuroinflammation, the "flame" of the brain. Although details differ and matter, neuroinflammation exacerb...

Already rocked by decades of political interference, corporate influence, mismanagement, and partisan efforts to undermine its authority, the expert bureaucracy, the "lifeblood" of the US administrative state, is now gasping for air. On 23 ...
