Yeast against the machine: Bakers' yeast could improve diagnosis

It's easier than ever to sequence our DNA, but doctors still can't exactly tell from our genomes which diseases might befall us. Now a research team is setting out to change this by going to basics -- to our billion-year-old cousin, baker's yeast. It turns out our billion-year-old cousin can reveal -- more reliably than leading algorithms -- whether a genetic mutation is actually harmful.
