Mining Bacteria for Antibiotics

Bacteria synthesize antibiotics to kill competitors; in fact, 70% of all antibiotics come from (or are inspired by) chemicals made by bacteria. Often, though, these bacterial secondary metabolite assembly lines have gone silent and are evident only in genome sequences, thus hiding potentially valuable new antibiotic compounds. Although cloning entire metabolic pathways into new hosts is possible, researchers don’t have many well developed tools available to facilitate such undertakings. Now researchers from the University of York have developed a combinatorial biosynthetic approach for mining silent metabolic pathways and potentially creating libraries of new antibiotic compounds.

Exploring the Biology of Eating Disorders

Although clear evidence supports the idea that eating disorders are biologically driven—they predominantly affect women and significantly alter energy homeostasis—a lack of well-defined animal models combined with the view that they are mainly behavioral abnormalities have hindered studies of the neurobiology of eating disorders. Now, researchers determined to find the biological roots of the disease and tease out the relationship between the psychiatric illness and metabolic disturbance have identified some of the genes involved and introduced new tools for studying eating disorders.

How to Culture Uncultured Organisms

Studying microbes has provided unparalleled insights into the molecular mechanisms governing cell functions, but expanding on such studies with new microbes depends on finding the right media for culturing the bacteria.  Now, researchers present a new way to approach these “unculturables” to get them growing and revealing their secrets.
