Humans Domesticated Yeast Through Bread-Making: Study
Max Kozlov | Dec 11, 2020 | 4 min read
Over centuries of cultivating Saccharomyces cerevisiae to make dough, bakers have put selective pressure on the species, causing it to diverge into two distinct groups, according to the authors.

The Inside Guide: The Gut Microbiome’s Role in Host Evolution
Catherine Offord | Jul 1, 2021 | 10+ min read
Bacteria that live in the digestive tracts of animals may influence the adaptive trajectories of their hosts.
Researchers in George Church&rsquo;s lab modified wild type ADK proteins (left) in <em >E.coli</em>, furnishing them with an nonstandard amino acid (nsAA) meant to biocontain the resulting bacterial strain.

Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.

Under one name the species is used in food fermentation, and under the other it is a drug-resistant cause of yeast infections.
Epigenetics: Genome, Meet Your Environment
Leslie Pray | Jul 4, 2004 | 10+ min read
©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat
Targeting Antibiotic-Resistant Bacteria with CRISPR and Phages
Anna Azvolinsky | May 18, 2015 | 3 min read
Researchers develop a CRISPR-based, two-phage system that sensitizes resistant bacteria to antibiotics and selectively kills any remaining drug-resistant bugs.
