Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions ...

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large ...

Two new studies suggest optical computing, which uses light to process data, is much closer to becoming a faster, more energy-efficient alternative to conventional systems. One study used an ...

Specifically, the researchers used optical image sensors that had previously been shown to be capable of imaging low-energy positrons in real-time with unprecedented resolution. “We had to strip away ...

Optical clocks can achieve levels of accuracy that could detect these changes. On a more practical level, accurate time is used to synchronize much of the infrastructure we rely on from banking to ...
