Mad Scientists Create Human Bread Yeast in a Lab - Futurism

A team of scientists at Delft University of Technology in the Netherlands managed to successfully insert human muscle genes into a bit of baker's yeast for the first time.

The human genes in question express a metabolic pathway that involves breaking down sugars to produce energy, the same mechanism that's a part of many common disorders (including, among others, cancer).

That means the engineered "humanized yeast" could open plenty of doors in the fields of drug screening and cancer research, proving once and for all that, yes, yeast can serve as an excellent tool in a scientist's arsenal.
