Most of the oxygen in the atmosphere is generated by the sea.

When it came to our atmosphere, however, it wasn't that much of a joke over the long term, because it turned out that we were losing oxygen, quite a lot of oxygen.

Ozone, a molecule made up of three atoms of oxygen, forms a thin layer of the atmosphere that absorbs harmful ultraviolet radiation from the Sun.

We now understand that those microbes have more impact on our climate and regulating CO2 and oxygen than plants do, which we always thought oxygenate the atmosphere.

Well, I have to tell you something very odd, and that is that being exposed to low oxygen does not always kill.

This top light is I'm sorry if I'm making you seasick this top light is actually a water quality display that shifts from red, when the dissolved oxygen is low, to a blue green, when its dissolved oxygen is high.

Moreover, if we succeed, it's going to be the most important transformation for life on the planet since, as Bill Joy says, we went from methane to oxygen in the atmosphere.

The first limitation is the oxygen oxygen toxicity.

And currently we're working on oxygen oxygen delivery on site.

If you give mice hydrogen sulfide, you can lower their demand for oxygen, and you can put them into oxygen concentrations that are as low as 5,000 feet above the top of Mt. Everest, and they can sit there for hours, and there's no problem.

Liquid oxygen

And, in fact, the animals we were working with in the lab these little garden worms, nematodes they were also dead when we exposed them to low oxygen.

Love is like oxygen.

Oxygen and hydrogen make water.

The primary purpose of the gas system is to provide oxygen, to replenish the oxygen that your body consumes.

There's going to be a lot of cheap rocketry that's going to come online in about six or seven years that gets us into the low atmosphere very cheaply.

Photosynthesis is modulated by oxygen, and we have an oxygen insensitive hydrogenase that we think will totally change this process.

It's called a carbon oxygen dwarf.

She tripped over her oxygen tank.

Water consists of hydrogen and oxygen.

And that atmosphere is very as dense as our own atmosphere.

So, in this room, there's 20 percent oxygen or so, and if we reduce the oxygen concentration, we will all be dead.

And because you can't bind the oxygen, maybe you wouldn't consume it, and then maybe it would reduce your demand for oxygen.

It inhales oxygen, just like we do.

We had lost seven tons of oxygen.

Stromatolites were the first to exhale oxygen.

It grew as light and oxygen increased.

Its oxygen consumption rate fell by tenfold.

I have an oxygen hose connected here.

The oxygen tanks didn't quite work right.

This planet has an inner atmosphere of water it s its inner atmosphere. It has two atmospheres a lesser, outer gaseous atmosphere, a lighter one.

And here's this incredibly simple molecule, a nitrogen and an oxygen that are stuck together, and yet these are hugely important for unclear our low blood pressure, for neurotransmission, for many, many things, but particularly cardiovascular health.

You get a hypoxia, or a lower oxygen.

Oxygen, hydrogen and zinc have their own signature.

I was so fascinated by that Oxygen commercial.

It's not hard it's just three oxygen atoms.

There's a built in oxygen concentrator down there.

Because of the movement I was wasting oxygen.

The technology for oxygen delivery is not new.

Trees give off oxygen and absorb carbon dioxide.

Water is made up of oxygen and hydrogen.
