Solving colibactin’s code
In an effort to understand how colibactin, a compound produced by certain strains of E. coli, may be connected to the development of colorectal cancer, Harvard researchers are exploring how the compound damages DNA to produce DNA adducts.

How new biosensors turn E. coli into something valuable
New biosensors developed by Wyss Institute core faculty member George Church enable complex genetic reprogramming of common bacteria like E. coli and could be leveraged for sustainable biomanufacturing, using the metabolic processes of bacterial cells to generate valuable chemicals and fuels.

Evolution in real time
After 26 years of workdays spent watching bacteria multiply, Richard Lenski has learned that evolution doesn’t always occur in steps so slow and steady that change can’t be observed.
