The weirdest things we learned this week: Curing syphilis with malaria, ejecting bears from planes, and discovering new beer yeasts

In 2009, a team of researchers at the University of Wisconsin-Madison, launched a five-continent search for the yeast mama. This portion of the genetics is what gives lager style beer its primary characteristic: the ability to ferment cold. The first hit came from Argentina, a 99.5 percent match from a growth on a beech tree. They named it Saccharomyces eubayanus.
