Sometimes you wonder what if any benefit certain research programs will produce. Not to criticize because TPP's research has never been focused on application. But this is certainly useful and important. Researchers have identified the yeast gene that makes the protein that coats the carbon dioxide bubbles that creates the foamy head on beer! Now ignorance of this gene has not in the least prevented humans from using yeast to make beer over the last 8,000 years or so, but maybe the head on beer will improve thanks to this research.
