Sometimes these copper glazes are crystalline, with regularly ordered arrays of atoms. But they can also be glassy,

meaning that the atoms are disordered rather. In fact, it seems likely that copper smelting stimulated not only glazing but the production of glass itself,

That's because unlike nitrogen or oxygen, carbon dioxide molecules absorb the Sun's heat rays

Nitrogen is a vital constituent of all proteins as well as other important molecules including DNA, but we can only use nitrogen once it has been broken down and combined into an  organic  molecule,

such as an amino  acid, for example. So for thousands of years, humans have come up with ingenious ways of replacing the nitrogen oe

which now contains more carbon dioxide molecules oe and the oceans, which are more acidic because more of that carbon dioxide is dissolving into them.

The real final frontier isnt in outer-space or inner-particle. Its in the space between mankinds ears.

Epigenetic regulation refers to the turning on and off of genes by molecules not the genes themselves.

For example, a series of cloned mice were shown to express an RNA molecule that inactivated one of the female s X chromosomes.

Antioxidants help keep other molecules in the body from producing free radicals which can damage cells

The new results published in several studies today (June 3) in the journal Proceedings of the National Academy of Sciences (PNAS) were found by analyzing the fraction of different carbon isotopes or atoms of the same chemical with different molecular weights

 Based on levels of radioactive isotopes or atoms of the same elements with different molecular weights the team estimated that the site was occupied almost continuously between 9800 and 12000 years ago.

but now experts say it may be carried on airborne dust particles. I would not rule it out Dr. Montserrat Torremorell of the University of Minnesota's College of Veterinary medicine told Reuters.

The project adopted two distinct approaches to evolutionary studies molecular data which examines DNA and morphological data

10 Coolest Genome sequences The molecular team gathered DNA sequences of living animals while the morphology team analyzed the anatomy of both living and extinct mammals.

The molecular team was limited largely to living mammals because researchers currently cannot extract genetic material from fossils more than 30000 years old so morphological data was key
