A new Stanford-designed optical amplifier uses energy recycling in a resonator to deliver strong, low-noise amplification with far less power.

The Atacama Cosmology Telescope’s final data release confirms a major cosmic discrepancy and rules out many attempted solutions.

Great sports saloons are as performant and engaging as sports cars and supercars but with the practicality to suit almost all day-to-day jobs. These are our current favourites.

Copper Blue deserves to breathe. Howie Weinberg knew that in 1992. The vinyl knows it by physics. It's only the digital reissues that have forgotten.

The entire space feels cohesive, like you’re moving through one continuous rock and roll fever dream rather than just a series of disconnected mini golf holes. For Minnesota residents tired of the ...

Mount Shavano rises to the north, one of Colorado’s fourteeners, offering summit seekers a challenging but achievable climb. The mountain doesn’t care about your fitness tracker or your Instagram ...

“This project started with a simple question: why do basketball shoes squeak?” Adel Djellouli, a study co-author and ...

In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials ...

Basketball shoes on a gym floor, bicycle brakes in need of a tune-up, or the squeal of tires are everyday examples of squeaking sounds. Such sounds have long been attributed to stick-slip friction, or ...

The squeaking of sneakers on a gym floor is usually attributed to friction, specifically a stick-slip variety that involves cycles of sticking and sliding between two surfaces. But that model is best ...

CU Boulder researchers have designed microscopic “racetracks” that trap and amplify light with exceptional efficiency. By using smooth curves inspired by highway engineering, they reduced energy loss ...

Live music can engage more than just one sense, despite it being an auditory medium. Lighting and visual effects can enhance the listening experience, but it is unclear if they can also affect the ...
