Curved spacetime in a quantum simulator

The theory of relativity works well when you want to explain cosmic-scale phenomena—such as the gravitational waves created when black holes collide. Quantum theory works well when describing particle-scale phenomena—such ...

Researchers devise a simpler way to mimic aspects of human vision

Mimicking the performance of the human visual system is viewed as a difficult endeavor because of the extremely complex optical elements involved. In new work, researchers show that it's possible to create a lens system that ...

Revealing how an embryo's cells sync up

Scientists have known that when a mouse embryo is developing, the cells that will become its spine and muscles switch specific genes on and off repeatedly, in a synchronous fashion. However, there are deep mysteries about ...

Self-checking algorithm interprets gravitational-wave data

When two black holes merge, they emit gravitational waves that race through space and time at the speed of light. When these reach Earth, large detectors in the United States (LIGO), Italy (Virgo) and Japan (KAGRA) can detect ...

Study outlines scenarios leading toward a circular food system

The EU wants to make the transition to a circular food system, where waste is minimized, waste products are recycled and our impact on the planet is reduced. But what will we eat in the circular food system? What kinds of ...

Cloud-resolving climate model meets world's fastest supercomputer

Focused on the accuracy of climate predictions, a computational team led by Sandia National Laboratories recently achieved a major milestone with a cloud-resolving model they ran on Frontier, the world's first exascale supercomputer.
