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.

How earthquake swarms arise

A new fault simulator maps out how interactions between pressure, friction and fluids rising through a fault zone can lead to slow-motion quakes and seismic swarms.

Slow-light beam-steering

Researchers have fashioned ultrathin silicon nanoantennas that trap and redirect light, for applications in quantum computing, LIDAR and even the detection of viruses.

New quantum science fellowship

Five fellows comprise the first cohort of Stanford’s new Bloch Fellowship in quantum science and engineering. The fellows program is a central component of the Stanford-SLAC initiative known as Q-FARM, which aims to advance a second wave of discovery and innovation in quantum mechanics through interdisciplinary collaborations.

Storing data on 2D metals

Researchers have invented a way to slide atomically-thin layers of 2D materials over one another to store more data, in less space and using less energy.
