Secret to stress relief

Text:

Yeast’s ability to grow, divide, age and metabolize food is similar to human cells and provides researchers with a nearly perfect specimen to study cell processes and genetic variation. Biologist Jennifer Gallagher is taking advantage of the organism’s functions to examine how individuals would respond to stress at a molecular level, and the effects herbicides, such as the common household weed killer Roundup, have on genes. Because yeast can be preserved for decades, her research team will continue to compare effects of Roundup on yeast from 100 years ago to now.
