Those molecules could then either be blended into ethanol, or burned directly in a high-octane fuel.
Over the years, a number of scholars have tried to figure out what typically would happen to all those molecules.
Given that those molecules are absorbed at different wavelengths, the machine can measure the amount of absorption and calculate the concentration of greenhouse gases in parts per million.
FORBES: Going For The Green: Measuring The London Olympics' Carbon Footprint
The light does not form an image of the reacting molecules, but its interaction with those molecules specifically, which frequencies are absorbed, and how strongly allows Dr Zewail and his followers to work out how the molecules distort and reorganise themselves during the course of a reaction.
Although they occur in most cells, they crop up in particularly large numbers in cells of three kinds: those that move a lot, those that transport molecules in and out a lot, and tumour cells that are resistant to many different drugs (which are usually cells that are able to get rid of lots of foreign toxins).
This fantastic plastic has molecules far longer than those of regular polyethylene, and these molecules are, in addition, packed tightly into a crystal structure rather than being scattered at random.
Most smell researchers think the way that we smell has to do only with the shapes of odour molecules matching those of receptors in our noses.
The researchers are now screening small molecules to look for those that might increase SNX27 production or function in the brain.
Epigenetic changes are heritable changes to the regulation of a cell's genes, caused by extra molecules being attached to those genes.
One of these molecules, resveratrol, is found in red wine which created excitement among those who think that a wine-rich diet is part of the explanation for the healthy old age apparently enjoyed by many who live in southern Europe.
