Researchers have developed a programmable optical device for high-speed beam steering.

A new method uses optics to accelerate machine-learning computations on smart speakers and other low-power connected devices.

The stars circle each other every 51 minutes, confirming a decades-old prediction.

Refining current opacity models will be key to unearthing details of exoplanet properties — and signs of life — in data from the powerful new telescope.

The materials’ stiffness increases up to 40 percent, in a reversible effect, the researchers report in a study that also explains the phenomenon's atomic origins.

The technique opens a door to manufacturing of pressure-monitoring bandages, shade-shifting fabrics, or touch-sensing robots.

A new technique could improve the precision of atomic clocks and of quantum sensors for detecting dark matter or gravitational waves.

Inspired by fireflies, researchers create insect-scale robots that can emit light when they fly, which enables motion tracking and communication.

The new design is stackable and reconfigurable, for swapping out and building on existing sensors and neural network processors.

The image reveals a glowing, donut-shaped ring at the Milky Way’s heart.
