Millions thrive at high altitudes due to remarkable genetic adaptations. Tibetans, for instance, possess a gene variant allowing efficient oxygen use without dangerously thick blood. Andeans and ...

A 91-year-old man was admitted to the hospital with weight loss, dyspnea, and eosinophilia. An anteroposterior chest radiograph obtained 2 months earlier showed bibasilar patchy opacities. A ...

With challenges around usability, trust and regulation addressed, RTBF can play a meaningful role in shifting healthcare from ...

Personal Perspective: "Normal" isn’t perfection but a statistical range based on population data. Diagnoses compare ...

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 ...

Scientists sent hurricane-level floods into a Maryland forest to find out what extreme weather and sea-level rise mean for coastal woodlands Kristen Goodhue PNNL Earth scientist Peter Regier (left) ...

Researchers in the U.S. have found that exposure to low oxygen levels — known as hypoxia — early in life can cause pulmonary hypertension (PH) by permanently altering lung blood vessel development.

In the thin air above 3000m, climbers battle fatigue, cold and altitude sickness, but what if the damage outlasts the expedition? A team at the University of Edinburgh has shown that even a brief ...

Researchers at Karolinska Institutet have discovered how cells can adjust their gene activity to survive when oxygen runs low. The study, published in Nature Cell Biology, reveals that cells use a ...

An implantable zinc magnesium battery generates hydrogen and removes oxygen inside tumors, triggering a hypoxia-activated drug and achieving strong, localized tumor suppression in mice. (Nanowerk ...
