Physics Today December 2020In the December 2020 Issue

Exploring Cultural Heritage through Acoustic Digital Reconstructions
Simulating the acoustics of destroyed or altered amphitheaters, cathedrals, and other architectural sites recreates their sonic grandeur. — Brian Katz, Damian Murphy, and Angelo Farina

Ultrasound in Air
Experimental studies of the underlying physics are difficult when the only sensors reporting contemporaneous data are human beings. — Timothy Leighton

Ocean Acoustics in the Changing Arctic
Recent changes in ice cover and ocean stratification have been so large that acoustic measurements made during the Cold War no longer reflect current conditions. — Peter Worcester and Megan Ballard

Computational Phonogram Archiving
A general approach to analyzing audio files makes it possible to recreate the sound of ancient instruments, identify cross-cultural musical properties, and more. — Michael Blaß, Jost Leonhardt Fischer, and Niko Plath

High Radiation Dose Rates May Improve Cancer Therapy
The ill-understood effect is gaining momentum and opening new avenues of research. CERN’s Compact Linear Collider and other particle accelerators are contributing. — Toni Feder

Making Robots Microscopic
Wirelessly powered and mass manufactured, the dust-sized robots can crawl, survive harsh environments, and be injected through a hypodermic needle. — Marc Miskin
