CHEMISTRY IS...

Chemistry is the logic of matter and forces at atomic and molecular level.

CELLS ARE FULL OF SWITCHES

Surprise, surprise! Analysis with a supercomputer has found thousands of molecular switches in cells (see the full article in ScienceDaily).

But the researchers' assumption that 'evolution might stumble upon a switch' overlooks the obvious--that it processed its way to making a new one because it calculated a need for it.

Ditto the insertion, deletion and transfer of segments of DNA in organism. The processing over large timescales with low-power molecular-logic machines is slowly working things out.

Bio-molecular logic is a self-programming, self-modifying, self-improving, self-exploratory, self-analysing network of molecular machines beavering away at the base of an organism.

RESEARCHERS WATCH RNA MACHINES WORKING

Researchers have reported that they are the first to observe the dynamic, ratchet-like movements of single ribosomal molecules in the act of building proteins from genetic blueprints--reports
ScienceDaily.

The astonishing accuracy and complexity of the system is ahown in another ScienceDaily article, which describes how it not only selects the right molecules but can reject wrong ones, even discriminating between ones that are little different.

Life's superb machinery at work.
