Accelerator-on-a-chip advance

A new advance by Stanford engineers could lead to particle accelerators being widely available in science, medicine, and industry.

New chip-scale laser isolator

Using well-known materials and manufacturing processes, researchers have built an effective, passive, ultrathin laser isolator that opens new research avenues in photonics.

Are we missing a crucial component of sea-level rise?

Across Antarctica, some parts of the base of the ice sheet are frozen, while others are thawed. Scientists show that if some currently frozen areas were also to thaw, it could increase ice loss from glaciers that are not currently major sea-level contributors.

A new, faster way to browse physics-based animations

Simulators can jumpstart the work of animation, but often return an overwhelming array of options for the animator to sort through. A new browser refines those options to a more manageable number.

Next-gen battery solutions

A new mathematical model has brought together the physics and chemistry of highly promising lithium-metal batteries, providing researchers with plausible, fresh solutions to a problem known to cause degradation and failure.

Gravity telescope to image exoplanets

A futuristic technique conceptualized by Stanford scientists could enable astronomical imaging far more advanced than any present today.

A new way to control atomic interactions

A new study demonstrates – for the first time – how to versatilely program atoms to share information regardless of their spatial location, opening paths forward in fundamental physics and advanced computing.

A quantum view of ‘combs’ of light

Frequency microcombs are specialized light sources that can function as light-based clocks, rulers and sensors to measure time, distance and molecular composition with high precision. New Stanford research presents a novel tool for investigating the quantum characteristics of these sources.

Astronomy’s newest 10-year plan focuses on alien Earths

Stanford astronomer Bruce Macintosh was a co-author of the latest “Decadal Survey,” a once-in-a-decade report that helps set the research priorities for the astronomy and astrophysics communities. Those priorities will include the identification of other habitable Earth-like worlds and determining whether life exists elsewhere in the universe.

Researchers test physics of coral as an indicator of reef health

New research shows that physics measurements of just a small portion of reef can be used to assess the health of an entire reef system. The findings may help scientists grasp how these important ecosystems will respond to a changing climate.

Why warming makes weather less predictable

A Stanford University study shows chaos reigns earlier in midlatitude weather models as temperatures rise. The result? Climate change could be shifting the limits of weather predictability and pushing reliable 10-day forecasts out of reach.

Time crystal in a quantum computer

A team of researchers including ones from Stanford and Google have created and observed a new phase of matter, popularly known as a time crystal.

Adding sound to quantum simulations

Aiming to emulate the quantum characteristics of materials more realistically, researchers have figured out a way to create a lattice of light and atoms that can vibrate – bringing sound to an otherwise silent experiment.

New model points to solution to global blood shortage

A mathematical model of the body’s interacting physiological and biochemical processes shows that it may be more effective to replace red blood cell transfusion with transfusion of other fluids that are far less in demand.

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.
