The density of water molecules within the leaf is typically 60 times greater than the density of carbon dioxide in the air, and the diffusion rate of the water molecule is greater than that of the carbon-dioxide molecule.

Rosenberg's grandfather Michael Rhodes was a chemist who in the 1950s led the invention of the water-repelling molecule at the heart of Hycrete's additive.

The water contained DNA, the same molecule used by every organism on earth to carry its genetic information, its blueprint.

So depending on the relative humidity and temperature, 100 or more water molecules diffuse out of the leaf for every molecule of carbon dioxide that diffuses in.

That could cause the oxygen to become liberated from water molecule and turned into a gaseous form.

Soap is made of long molecules with ends that behave differently: One end of the molecule is attracted to water and the other is repelled by it.

But the molecule isn't soluble in water.

If you filled the entire solar system with water, and mixed in one molecule of duck liver, it would be much more concentrated than this stuff.

Anything but a neutrino is likely to be screened out by the surrounding rock, so the flashes of light created when a neutrino hits a water molecule are not swamped by background glare.
