(Phys.org) —Imagine a physician, sitting in a stadium press box, equipped with technology that makes it possible to continuously monitor each player's physiological signs that indicate concussion.
Unlike healthy cells, cancer cells thrive when deprived of oxygen. Tumors in low-oxygen environments tend to be more resistant to therapy and spread more aggressively to other parts of the body.
The evolution of the first animals may have oxygenated the earth's oceans – contrary to the traditional view that a rise in oxygen triggered their development.
(Phys.org) —Research at the University of Liverpool has explained how cells behave when placed in a low oxygen environment, a development that could have implications for cancer patients and other serious illnesses.
Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits.
One of science's strongest dogmas is that complex life on Earth could only evolve when oxygen levels in the atmosphere rose to close to modern levels. But now studies of a small sea sponge fished out of a Danish fjord shows ...
A disposable organic sensor that can be embedded in a diaper and wirelessly let a carer know it needs changing was unveiled by Japanese researchers on Monday.
(Phys.org) —All but a few eukaryotes die without oxygen, and they respond dynamically to changes in the level of oxygen available to them. UCD scientists used genetic analysis to pinpoint an evolutionary switch in regulating ...
Air flows mostly in a one-way loop through the lungs of monitor lizards – a breathing method shared by birds, alligators and presumably dinosaurs, according to a new University of Utah study.
How long has Earth's atmosphere included oxygen? A recent paper suggests low levels of oxygen appeared in the atmosphere approximately 2.95 billion years ago. That's about 550 million years earlier than previously thought.
