The American Astronomical Society (AAS) has announced its awards and prizes for 2023. This includes three former scholars in the School of Natural Sciences, who were given a Buchalter Cosmology Prize.

In a recent paper, published in Physical Review Letters, researchers have discovered a new property of scattering amplitudes—fractional scaling—based on their study of sound waves through solid matter. Its recognition may help the study of scattering amplitudes in many different contexts, from particle physics to cosmology.

Not everything needs to be seen to be believed; certain things are more readily heard, like a train approaching its station. In a recent paper, published in Physical Review Letters, researchers have put their ears to the rail, discovering a new...
