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 ...

A new study says observations from the NASA Fermi space telescope suggest a halo of dark matter around the center of our galaxy, but more information is needed to confirm the result. When you purchase ...

Nearly a century after astronomers first proposed dark matter to explain the strange motions of galaxies, scientists may finally be catching a glimpse of it. A University of Tokyo researcher analyzing ...

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three-dimensional ...

Dark energy and dark matter refers to the unseen energy and matter components of the Universe. Dark matter is invisible, non-baryonic matter hypothesized to explain phenomena including gravitational ...

A pulse oximeter measures blood oxygen levels at home and in healthcare settings. Abnormally low readings on a pulse oximeter might require medical care, especially if they are below 92%. Skin color ...

Dec. 21, 2025 Superconductors promise loss-free electricity, but most only work at extreme cold. Hydrogen-rich materials changed that—yet their inner workings remained hidden because they only exist ...

To take a pulse oximetry reading, turn on the device, place it on your fingertip, sit still, and wait for a stable reading. Normal oxygen saturation levels range from 95% to 100%; levels below 92% may ...

Conclusions: SpO2 and PR measurements may be inaccurate across all skin pigmentation groups, breaching U.S. Food and Drug Administration guidance and industry standard thresholds. Pulse oximeters ...
