Yeast screens explore the therapeutic potential of chemical rescue. Anyone who’s worked in a lab knows that sinking feeling of discovering that the temperature of an incubator, carefully set the night before, has crept up high enough to ruin the experiment. While such a mishap usually spells disaster, occasionally, it can lead to an unexpected…

An evolutionary approach outperforms a design approach in modeling protein sequence variation. Over generations, evolution shapes proteins, leading to variation in their amino acid sequences both between and within species. Despite our ever-increasing knowledge of the physical constraints that guide protein structure, advanced modeling techniques don’t capture the site-specific variability observed in natural proteins. Bafflingly,…

Wild yeast aren’t picky about their mates. For Saccharomyces cerevisiae, setting the mood is as simple as providing an abundant supply of nutrients, which prompts each yeast cell to search for another of the opposite mating type. If a lonesome yeast cell can’t find a suitable partner, it’s no problem—it can alternate between mating types,…

While the science behind the synthetic yeast genome project is cutting edge, the ethical questions surrounding it aren’t new. The scientists of the Sc2.0 project have a goal that sounds akin to science fiction – they’re working toward building a completely synthetic yeast genome. This new strain of Saccharomyces cerevisiae, affectionately named Sc2.0, will be…
