NASHVILLE, Tenn. -- Racial biases persist in the use of pulse oximetry devices for patients with acute hypoxemic respiratory failure (AHRF) requiring very high levels of oxygen support, a ...

NASA's Hubble Space Telescope captures the magnificent starry population of the Coma Cluster of galaxies, one of the densest known galaxy collections in the universe — and where the effect of dark ...

Few things in the universe are as perplexing as dark matter — the invisible and exotic “stuff” that is thought to make up most of the matter in galaxies. The theory goes like this: To reconcile our ...

An unexplained glow that appears to emanate throughout the Milky Way’s outer regions could be our first hint of what dark matter is made of, but astronomers say it is too early to know for sure. Dark ...

In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark ...

Dark matter may be invisible, but scientists are getting closer to understanding whether it follows the same rules as everything we can see. By comparing how galaxies move through cosmic gravity wells ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Astronomers have found the strongest evidence yet for the existence of dark stars, a type of enormous star in the early universe that is partially powered by dark matter. If confirmed, these ...

Although we’re still searching for observational evidence of dark matter, scientists haven’t been able to account for about 15 percent of the regular matter in the universe with just stars, planets, ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Microsoft announced Wednesday that it has invented an entirely new kind of quantum computer. Its new quantum chip, Majorana 1, is a quantum processor analogous to transistors in classical computers’ ...

Microsoft’s new “topological qubit” is not based on a solid, liquid or gas. It is another phase of matter that many experts did not think was possible. Microsoft’s new quantum chip is based a new ...
