Nanobubbles are invisible, mysteriously stable, a thousand times thinner than a human hair, and surprisingly versatile.
A physical chemist outlines the promises and risks associated with methane fuel and describes why SpaceX and Blue Origin use it in their superheavy rockets.
As lunar missions are back in vogue with engineering more sustainable human presence on the Moon in mind, there’s no getting away from the fact that you can’t breathe on a satellite that has no atmosphere.
The companies that drilled these cores decades ago couldn’t have known the scientific treasures inside.
A chemical signature in a lunar rock offers new insights into what early oxygen conditions were like on the Moon.
At altitudes over 2,400 metres, lack of oxygen — a condition called hypoxia — can cause acute mountain sickness. Incidence rises with altitude, but there are ways to lower risks.
Until now, it’s been very hard for scientists to establish a detailed timeline of the early evolution of bacteria.
Environmental stress in evolution can be reframed as a powerful engine of innovation, not simply a barrier to survival.
Scientists are exploring the deep ocean to understand how oxygen can be produced there without sunlight.
How much oxygen does the military need for wounded soldiers? Turns out not much. Military-civilian research is paving the way for new developments.
Organic soils, one of the pillars of Québec’s food self-sufficiency, could disappear within 50 years. Fortunately, the application of straw or wood chips could regenerate these soils.
A study has found rocks at the bottom of the ocean can make oxygen.
Our blood is red because of something called haemoglobin, which helps carry oxygen around our bodies.
Inhaling air is how you get the oxygen your body needs to turn your food into energy. Other living things use different strategies.
An unusual lake with distinct layers of low-oxygen and high-iron water lets researchers investigate conditions like those in the early Earth’s oceans.
When water warms, it holds less oxygen, and this can harm aquatic life and degrade water quality. A new study finds that climate change is driving oxygen loss in hundreds of US and European rivers.
Crying triggers changes in how a newborn baby gets their oxygen. But not all new babies cry, and it’s not always a problem.
Imagine an NBA game played outdoors in August, with no substitutions and players wearing snowsuits, gloves and ski masks. Race car drivers routinely compete under similar conditions.
This year is shaping up to be one of the deadliest on record. Here are some of the challenges climbers face when attempting to reach the summit of Mount Everest.
