Alfred Nobel made his fortune through the invention of dynamite.
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.

What exactly is inside those red fire extinguisher canisters, and does it work better than water?
Take a deep breath.
A sigh is the brain's way of stopping the tiny sacks in your lung from collapsing.
The more fuel there is for the fire to burn, the bigger the fire. Leaves, trees and grass fuel the fire.
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.
Even a small cloud can weigh as much as four tonnes – but gravity, chemistry and temperature keep them floating in the sky.

It is possible to split water into oxygen and hydrogen gas in zero gravity using sunlight, shows new study.
Climbing a mountain has more to do with how your body deals with altitude, which you can’t control.
While acclimatising is more important, here's the training you should undertake to go mountain-climbing.
How well you’ll cope on a mountain has little to do with how fit you are.

You can't know how altitude will affect you until you're up there. Here's why people have different reactions to less atmospheric oxygen.
The first piece of the International Space Station was launched in 1998.
The students of class 3F at Ferny Grove State School want to know how they get oxygen into the International Space Station.

Health benefits of being close to nature are well established, but the rise of apartment living means we can't always be close to greenery.
Scientists are perplexed by the detection of molecular oxygen in comet 67P’s tail – a completely unexpected discovery.
Why finding molecular oxygen on comet 67P is a really big deal.
Enormous algal blooms off Cornwall, which can lead to low oxygen waters.
The world’s oceans are plagued with the problem of “dead zones”, areas of high nutrients (such as nitrogen and phosphorus) in which plankton blooms cause a major reduction of oxygen levels in the water…
Yawning acts to cool the brain, according to a new study. Researchers recorded yawning habits of people in Vienna, Austria…
Early microbial communities, such as stromatolites, are intrinsically linked with the rise of oxygen.
