A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar ...

Physicists have found a way to measure the time involved in quantum events and found it depends on the symmetry of the ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

The concept of time has troubled philosophers and physicists for thousands of years, and the advent of quantum mechanics has not simplified the ...

Having different chronotypes, or being more active in the morning vs. afternoon, may play an important role in preserving muscle mass and strength, and metabolic health, according to a new study.

Abstract: Open-top two-photon light sheet fluorescence microscopy was applied to various skin cancer specimens for high-depth high-throughput optical pathology and precision cancer detection.

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...
