Microbiome studies have yielded hundreds of ideas for ways to detect and influence human health, but the field struggles with reproducibility challenges that hamper bringing these goals to fruition. Identical tubes of fecal matter should help.
How a Microbe Resists Its Own Antibiotics

Researchers reveal the molecular mechanisms of Streptomyces platensis’s defense from its own antibiotics, which inhibit fatty acid synthesis in other microbes.
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.

©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
Bacteria Harbor Geometric “Organelles”
Amber Dance | Dec 1, 2018 | 10+ min read
Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.
