Cyborg yeast do what you tell them
Can you imagine being able to talk to your yeast? What if you could tell the billions of cells in your carboy to do this or to do that? While this might sound like fantasy it’s actually being done at the Swiss Federal Institute of Technology Zurich. By using light the reserachers were able to impact the yeast’s ability to produce a specific protein. "upon shining red light in, they could track how much a population of yeast cells was expressing the gene, and apply the deeper red to curb that gene expression” (BBC). Breweries could actually use light to influence the taste of a beer. How crazy is that?
