Nitric oxide production by immune cells is one of the key mechanisms that our bodies use to destroy diseased cells. Enhancement of these types of immune responses is seen consistently with many medicinal mushrooms that have been tested by cancer researchers.

What does that suggest when a compound this simple plays such an important role? To me it suggests that nitric oxide is one of the most primitive elements of cellular signaling, that it goes way back into evolution.

Cargo ships typically burn dirty fuel that releases pollutants like nitrous oxide and sulfur dioxide, which can cause various cancers and childhood asthma for people living in port cities.

I am not surprised that other gases may participate in cellular signaling and regulation. Our early work with nitric oxide was just the beginning. I'm sure more will be discovered.

Nitric oxide is a key biological messenger within the body. When released by the cells lining your arteries, it makes the walls of the arteries relax, allowing more blood to flow.

Carbon dioxide isn't the only greenhouse gas out there. Other substances, such as water vapor and nitrous oxide, also trap heat to varying degrees.

During the course of my research, I had had occasion to examine not only simple compounds, salts and oxides, but also a great number of minerals.

Polish Scientist

Without enough nitric oxide, your arteries can stiffen, raising blood pressure and your risk of heart attack.

There are very few things in the body that nitric oxide doesn't regulate.

Nitric oxide was known for destroying things.

Used in scientific contexts, especially chemistry. May not be familiar in everyday conversation.

Scientific Term

Oxides are important compounds. Knowing them helps understand Earth's elements and reactions.

Understanding Compounds

Familiarize with common oxides such as rust (iron oxide) and breath (carbon dioxide).

Common Oxides

 That's more than the emissions from all electricity and industry, or from all the world's planes, trains and automobiles. Most agricultural emissions come from tropical deforestation, methane from animals and rice fields, and nitrous oxide from over-fertilizing. There is nothing we do that transforms the world more than agriculture. And there's nothing we do that is more crucial to our survival.
