Engineered Yeast Makes Hoppy Flavors

Can you brew a hoppy beer without hops? Beer purists might regard the idea with suspicion, but researchers at UC Berkeley, with some help from UC Davis’ “Pope of Foam,” have shown that you can brew a tasty hoppy beer using gene-edited yeast to replace hop flavors.

According to Charles Denby, a former postdoctoral researcher at UC Berkeley, growing hops uses a lot of water – 50 pints of water to grow enough hops (the crumbly flowers of the hop vine) for a pint of craft beer.

Nobel Medicine Prize for “self-eating”

“Gnothi seauton” or “Know thyself,” said the Ancient Greeks; but they might have also said, “eat yourself.” For biologists, autophagy or “self-eating” is the process that cells use to recycle material inside the cell. It breaks down defective proteins and molecules, disposes of invading viruses and bacteria, provides an energy source when food is lacking and generally keeps cells fit and healthy. Problems in autophagy are implicated in cancer, aging, infectious disease and degenerative disorders.
