Iron-breathing bacteria might have delayed Earth’s oxygenation for almost one billion years

Inhale iron, exhale rust.

Meet the fish that can hold its breath underwater

A deep-sea creature is the first fish that we know of that holds its breath underwater.

Comet-inspired reactor could create oxygen for astronauts

Comets seem to release molecular oxygen all the time — and some scientists have recreated the process on Earth.

The ISS starts experimenting with a photo-bioreactor

A hybrid bio-technology could pave the way for future space missions.

There are arsenic-breathing microbes in the tropical Pacific, a new study finds

Oxygen? In this economy?! Pffff.

The European Space Agency wants to mine the moon for oxygen and water

Should everything go according to plan, ESA wants to launch the mission by 2025.

Comet 67P harbors oxygen molecules as old as the Solar System

I wonder if it smells stale.

Denying cancer cells one key amino acid might destroy treatment-resistant tumors

Attack the enemy where he is unprepared, appear where you are not expected.

World’s largest dead zone identified in the Gulf of Oman — it’s nearly the size of Florida

“Piracy and geopolitical tensions” kept it hidden from the scientific community until now.

Long-term exposure to mictrogravity can lower physical fitness down by half

And exercise doesn’t fix it.

The African naked mole-rat can keep its brain alive for more than 5 hours with no oxygen

Nifty trick.

The oxygen in the oceans has decreased by 2% in the past 50 years

It’s like the ocean is having a heart attack.

Early life kept oxygen in check and stalled evolution for billions of years, model suggests

Evolution doesn’t always procrastinate. But when it does, it’s for 2 billion years.

Earth’s oxygen has been emigrating to the Moon for billions of years, study finds

Who wouldn’t?

A whole new branch of life could have evolved and died off on Earth 2,4 billion years ago

There’s no proof. But the conditions were right for it to happen.

Ancient rocks reveal causes of Earth’s greatest mass extinction event

The new findings call our current theories on the mass extinction event into question.

Rocks prove Mars used to resemble the Earth a lot — but no, that doesn’t mean there was life on it

But maybe our neighbour wasn’t always so red-faced after all.

Water-breathing scuba mask design still has a way to go

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.

Big Surprise: Rosetta finds primordial oxygen on a comet

For the first time, astronomers have detected primordial oxygen gassing out from a comet

Algae and bacteria will provide oxygen for astronauts living on Mars

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.
