Without yeast, there is no beer.  Yeast occurs naturally and for millennia, it operated mysteriously. After the invention of the microscope, scientists could see and start to isolate and control yeast.  Now, thanks to new scientific developments, there are new yeast strains, designed to work better in current breweries, with current ingredients and to produce currently in vogue flavors.

There is probably no other area in brewing where science is making beer better.
