Scientists discover oxygen production in the deep sea, challenging everything we know about ocean life.
A new study shows Earth's Great Oxidation Event was a prolonged, chaotic process lasting 200 million years with fluctuating oxygen levels
A planet's atmosphere would need to contain at least 16 percent oxygen to support fire.
Europa produces about 100 times less oxygen than previously estimated.
It's not a good time to be a fish.
Good bots.
The transition towards longer days may have allowed cyanobacteria enough breathing room to produce enough oxygen to dramatically and forever alter Earth’s atmosphere.
NASA's new Mars rover is marking one milestone after the other, paving the way for human exploration of Mars.
We absolutely need this if we're to ever establish a colony on the Red Planet.
To build a moon base, you first need oxygen.
Scientists always thought animals need oxygen to survive. That's now a myth.
We though all life needs oxygen. We were wrong.
The findings offer renewed hope of finding oxygen on alien worlds.
Oxygen is rising and falling with the seasons unpredictably.
Oxygen, in the right place at the right time, makes for spectacular fossils.
This study rocks.
This used to mess up our calculations, but now we understand why.
It's all about the oxygen.
Inhale iron, exhale rust.
A deep-sea creature is the first fish that we know of that holds its breath underwater.
Comets seem to release molecular oxygen all the time -- and some scientists have recreated the process on Earth.
A hybrid bio-technology could pave the way for future space missions.
Oxygen? In this economy?! Pffff.
Should everything go according to plan, ESA wants to launch the mission by 2025.
I wonder if it smells stale.
Attack the enemy where he is unprepared, appear where you are not expected.
"Piracy and geopolitical tensions" kept it hidden from the scientific community until now.
And exercise doesn't fix it.
Nifty trick.
It's like the ocean is having a heart attack.
Evolution doesn't always procrastinate. But when it does, it's for 2 billion years.
Who wouldn't?
There's no proof. But the conditions were right for it to happen.
The new findings call our current theories on the mass extinction event into question.
But maybe our neighbour wasn't always so red-faced after all.
South Korean designer Jeabyun Yeon has just unveiled his new concept of a scuba mask that would allow anyone to breathe underwater without requiring air tanks. His design, named the Triton, includes two arms linked to a mouth piece. The branching arms are designed to extract free oxygen atoms from the water and supply breathable air directly to the user. But I'm not sold on it just yet.
For the first time, astronomers have detected primordial oxygen gassing out from a comet
NASA has partnered with a private company to design and build an oxygen production facility for a Martian outpost or colony. The make the oxygen, bacteria and algae would use the nitrogen-rich Martian soil to make the precious oxygen, essential for the astronauts' survival. It can be used to make air, water and fuel.
When under threat, the pufferfish quickly inflates into a spherical shape to help it ward off and escape predators. Until now, biologist had thought that in this state the pufferfish – also known as the blowfish, toadfish or sea squab – holds its breath all the while, but this assumption has been overturn by the findings […]
Researchers from Denmark have synthesized crystalline materials that can bind and store oxygen in high concentrations, releasing them when needed. A single crystal about the size of a sponge can suck all the oxygen from a room. Naturally, there are many potential applications for this type of technology. The most obvious one would be breathing underwater […]
Without oxygen, your brain would shutdown within five minutes or so and you, as a person, along with it. Deprived of this fundamental element, brain cells can’t produce energy anymore and wither and die. Breathing is important, that’s pretty settled but what happens if you can’t rely on your lungs anymore. A team of researchers led […]
Researchers at MIT found that individual cells in a bacterial colony will grow in a manner that is beneficial to the whole culture, even if this comes at a personal expense for the cell. With this in mind, it appears seemingly complex colony structures can be explained by an essentially simple behaviour. The findings could […]
Men have noses 10 cm longer than women (on average), even with the same body size This happens because men have more muscle tissue, which needs an extra oxygen intake This change starts happening during puberty Human noses come in all shapes and sizes, but despite that, generally speaking, men noses are significantly larger than […]
An international team of researchers led by Ralf Tappert, from the University of Innsbruck, reconstructed the composition of Earth’s atmosphere of the last 220 million years by analyzing modern and fossil plant resins. Their results indicate that atmospheric oxygen was considerably lower in Earth’s geological past than previously assumed – providing valuable information about current […]
Scientists from Department of Earth Sciences at the University of Oxford have analyzed the compositions of Martian meteorites found on Earth and data from NASA’s rovers, and they reached the conclusion that the Red Planet had an atmosphere pretty rich in oxygen 4 billion years ago. They compared Martian rocks with meteorites, and the fact […]
All life as we know it is primarily based on two elements: carbon and oxygen. Scientists at North Carolina State University investigating the conditions required for the formation of these life essential ingredients found that the Universe lives little room for error. Carbon and oxygen are formed as combustion byproducts after helium burns inside a […]
If you think today’s urban air, thickened with noxious smog, is terrible, just imagine how the Earth was filled in a shroud of hydrocarbons some 2.5 billion years ago. Back then, a haze dominated by methane engulfed the atmosphere such that light could barely reach the ground, similarly to what can be seen today on […]
For the first time, a NASA spacecraft has detected matter from outside our solar system – matter that drifted from some other part of our galaxy right to us. This interstellar material was spotted by Interstellar Boundary Explorer (IBEX), a spacecraft with the purpose of studying the outskirts of our solar system from its orbit […]
The paradox of water is that everybody knows it, but no one really understands it. It’s the most fascinating substance we have come across so far, and it still has many secrets for us. For example, the molecular structure of water still eludes scientists, and as a result, water still has many properties which we […]
Recently, the University of California, Riverside provided some materials that shocked me, to say the least. According to that research, scientists from all around the world have reconstructed changes in Earth’s ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. What they found was that the lack of […]
