Different amounts of UV hit different parts of the Earth at different times of year, so you can actually work out those stores of nitric oxide the nitrates, nitrites, nitrosothiols in the skin cleave to release NO.

These granules contain three essential plant nutrients.

What's a drug?

Nitrogen bonds to oxygen, which in turn....

40 grams thorium nitrate ?

Silver nitrate. raw.

I'm just going to show you a basic idea. We're all breathing air right now.

Inert nitrogen, high concentration of carbon dioxide crystals, methane...

I said, what kind of salts of potassium do you have? You know.

You'll need some of her hair... a little quicksilver, and... some aqua fortis.

200 pounds of ammonium nitrate fertilizer. I walked into my apartment...

And so I I did some experiments.

Nitrogen, oxygen. Looks like enough CO2 for green leafy things.

Unlike nitrates and peroxides, it gives off no signature.

And all of a sudden, if you have seven protons, you're dealing with nitrogen.

In summer, you might as well be at the equator.

It is the spectrum of a planet like Earth, showing a presence of nitrogen dioxide, as a clear signal of life, and oxygen and ozone.

The air we breathe consists of oxygen and nitrogen.

We inject our own aerosols into the atmosphere, and we have trace gases, and not just carbon dioxide it's methane, ozone, oxides of sulfur and nitrogen.

The algae are not going to suffocate because of CO2, as we would.

Nitrogen 1.25 .

Ventura mid winter, well, there's still a decent amount.

The air we breathe in, or inspire, has a mixture of gases including nitrogen, carbon dioxide and oxygen, which is the most important for our survival.

So what you can do is you can multiply those data by the NO that's released and you can calculate how much nitric oxide would be released from the skin into the circulation.

Zeolite it's not new zeolite removes nitrogen from air and nitrogen is 78 percent of air.

Each cylinder is about 10 percent ancient air, a pristine time capsule of greenhouse gases carbon dioxide, methane, nitrous oxide all unchanged from the day that snow formed and first fell.

If you look at carbon dioxide from burning tropical rainforest, or methane coming from cows and rice, or nitrous oxide from too many fertilizers, it turns out agriculture is 30 percent of the greenhouse gases going into the atmosphere from human activity.

Nitrous oxide stopped being used as an anaesthetic a long time ago.

Elements like oxygen and nitrogen, even countless dust particles, make up the air around us.

Include Nitrogens

We think that the skin well, we know that the skin has got very large stores of nitric oxide as these various other forms.

Furchgott, Ignarro and Murad, won the Nobel Prize for medicine back in 1998.

It's great. Lots of NO is released.

You can take virtually any parameter that matters for human well being nitrous oxide, methane, deforestation, overfishing

Turned solid when it met

And we then thought to ourselves, with those big stores,

This is liquid nitrogen.

They suffocate because they produce oxygen, and they don't really suffocate, but the oxygen that they produce is problematic, and they use up all the CO2.

But this is a bit like putting your head in a plastic bag.

The limitation of diving with air is all those dots in your body, all the nitrogen and all the oxygen.

And the reason for this, it turned out, after two or three years' work, was that in the skin we have huge stores not of nitric oxide, because nitric oxide is a gas, and it's released (Poof!) and in a few seconds it's away, but it can be turned into these forms of nitric oxide nitrate, NO3 nitrite, NO2 nitrosothiols.

My next step's gotta be oxygen.

There are three basic limitations of scuba diving.

This isn't Volvos this is volcanoes.

So if you're on the equator, December or June, you've got masses of NO being released from the skin.
