Circadian rhythms are endogenous time-keeping mechanisms that regulate physiological processes in response to external light-dark cycles.

Astronomers thought dark energy was a constant. But now, findings from the Dark Energy Spectroscopic Instrument provide even more evidence that it may be fluctuating ...

A new study by UCLA Health has discovered what researchers say is the first drug to fully reproduce the effects of physical ...

Dark energy is a mystery so daunting that it stretches and strains our most robust theories. The universe is expanding, ...

Imagine a boxer dodging a punch, a musician perfectly timing a note, or a driver anticipating a green light—the brain can be ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

The ability to conduct heat is one of the most fundamental properties of matter, crucial for engineering applications. Scientists know well how conventional materials, such as metals and insulators, ...

Three NASA-funded rockets are set to launch from Poker Flat Research Range in Fairbanks, Alaska, in an experiment that seeks to reveal how auroral substorms affect the behavior and composition of ...

For decades, the only viable tool to help stroke patients regain lost motor abilities — like walking or moving an arm — has ...

Neutrinos may be the key to quantum gravity, potentially leading to a unified theory combining quantum mechanics and general relativity.

The largest-ever three-dimensional map of the cosmos, plotting out some 15 million celestial objects, could help reveal the ultimate fate of the universe. Astrophysicists know that the universe is ...

Quantum gravity is the missing link between general relativity and quantum mechanics, the yet-to-be-discovered key to a ...
