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.

Blowfish don’t actually hold their breath when inflated

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 made by Australian researchers who

New crystal might allow us to breathe Underwater

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 or in outer space. We

Injecting oxygen filled particles lets you survive without breathing

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 by Harvard Medical School’s John N.

For the hive: bacteria grow altruistically for the greater good of the colony

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 aid researchers understand how bad

Why men have bigger noses than women

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 female noses, and apparently, no

Dinosaurs lived in low-oxygen world, amber shows

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 climate models, and questioning some

New study claims Mars had oxygen-rich atmosphere 4 billion years ago

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 that the surface rocks were

When laying the foundations for life, the Universe leaves little room for error

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 giant red star. However, for
