A microscopic sponge can be used to trap oxygen from the air.
These tiny organisms play a huge role in fighting climate change, but they’re under threat.
For now, governments and health services should invest in bedside oxygen concentrators and oxygen generators to supply whole hospital needs.
This discovery will shape the hunt for life on exoplanets.
Rather than breathing in and out through the mouth, fish use a one-way system, passing water in one direction over their gills.
It is becoming increasingly clear that there is plenty of brine on Mars.
You might think the more oxygen you breathe in the better. But too much oxygen can make you sick.
How ancient microbes survived in a world without oxygen has been a mystery. Scientists discovered a living microbial mat that uses arsenic instead of oxygen for photosynthesis and respiration.
A fetus needs oxygen long before its lungs work and it’s exposed to the air. Some ingenious biochemistry explains how the mother’s blood delivers it.
Have you ever felt a piercing pain in your head when you eat something cold?
In the most severe cases, COVID-19 patients need oxygen pumped directly into their airways, or even be hooked up to a machine that does the job of their heart and lungs.
New research suggests that Earth’s oxygenation didn’t require difficult and complex evolutionary leaps forward.
Oxygen is vital for life, so much so that cells can sense when there isn’t enough and adapt almost instantly. So how do they do it? The winners of the 2019 Nobel Prize for Physiology figured it out.
If the Amazon rainforest functions as our planet’s lungs, what do raging wildfires threaten? An atmospheric scientist explains why the fires, though devastating, won’t suffocate life on Earth.
What exactly is inside those red fire extinguisher canisters, and does it work better than water?
A sigh is the brain’s way of stopping the tiny sacks in your lung from collapsing.
Bushfires require three key ingredients to ignite: heat, fuel and oxygen.
Recent extreme rains and weather in the Midwest are causing a multitude of problems in the topsoil that much of the nation’s food supply relies on.
Put simply, it’s the outcome of a chemical reaction, which humans learned how to make some 400,000 years ago.
