Whatever with cleaner, renewable energy. Scientists have focused their attention on a far more important subject: brewing a better, cheaper beer. And it looks like they might have succeeded.

They key? Genetically modified yeast.

In a nutshell, yeast is the key ingredient in fermentation, and fermentation, of course, is what puts the alcohol in beer.

What those blessed scientists in Britain have created are “designer” genomes which can be spliced into the yeast’s DNA, making them better at making us beer, reports the Telegraph. With their upgraded genes, these super yeast cells can do things ordinary yeast just can’t, like survive longer under higher alcohol levels, allowing them to make stronger beer.

And as a bonus, these super yeast are more efficient than ordinary yeast at doing whatever it is they do, which means the beer will not only be more potent, it’ll be cheaper as well, in the end making the world a better place.
