Giant friction experiment at Kīlauea volcano

A new analysis of the 2018 collapse of Kīlauea volcano’s caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the conditions necessary to initiate the kind of caldera collapse that sustains big, damaging eruptions of basaltic volcanoes like Kīlauea and could help to inform forecasting and mitigation.

Physics professor explains exoplanets

A Q&A with astronomer Bruce Macintosh on what people should understand about exoplanets – planets outside our solar system – and what exoplanet research means for life on Earth.

New state of matter in one-dimensional quantum gas

By adding some magnetic flair to an exotic quantum experiment, physicists produced an ultra-stable one-dimensional quantum gas with never-before-seen “scar” states – a feature that could someday be useful for securing quantum information.

Combining light and sound to see underwater

The “Photoacoustic Airborne Sonar System” could be installed beneath drones to enable aerial underwater surveys and high-resolution mapping of the deep ocean.

Undersea origins of Earth’s mysterious Love waves

Supercomputer simulations of planetary-scale interactions show how ocean storms and the structure of Earth’s upper layers together generate much of the world’s seismic waves. Decoding the faint but ubiquitous vibrations known as Love waves could yield insights about Earth’s storm history, changing climate and interior.

Microlab tests for COVID-19 in 30 minutes

Using “lab on a chip” technology, Stanford engineers have created a microlab half the size of a credit card that can detect COVID-19 in just 30 minutes.
