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.
