- When and how did the elements of life in the Universe arise? - NASA Science
Following the Big Bang and the gradual cooling of the Universe, the primary constituents of the cosmos were the elements hydrogen and helium. Even today, these two elements make up 98% of the visible matter in the Universe. Nevertheless, our world and everything it contains—even life itself—is possible only because of the existence of heavier elements such as carbon, nitrogen, oxygen, silicon, iron, and many, many others. How long did it take the first generations of stars to seed our Universe with the heavy elements we see on Earth today? When in the history of the Universe was there a sufficient supply of heavy elements to allow the formation of prebiotic molecules and terrestrial-like planets

- The Many Benefits of Hydrogen Peroxide By Dr. David G. Williams
If any substance is interesting, it's hydrogen peroxide. Hydrogen peroxide should really be called hydrogen dioxide. Its chemical formula is H2O2. It contains one more atom of oxygen that does water (H20). By now everyone's aware of the ozone layer that surrounds the earth. Ozone consists of three atoms of oxygen (03). This protective layer of ozone is created when ultraviolet light from the sun splits an atmospheric oxygen molecule (02) into two single, unstable oxygen atoms. These single molecules combine with others to form ozone (03). Ozone isn't very stable. In fact, it will quickly give up that extra atom of oxygen to falling rainwater to form hydrogen peroxide (H202). (Bear with me: all this chemistry mumbo jumbo I'm going through actually will he...
