Bacteria self-organize to build working sensors

12-Oct-2017

Researchers at Duke University have turned bacteria into the builders of useful devices by programming them with a synthetic gene circuit. As a bacterial colony grows into the shape of a hemisphere, the gene circuit triggers the production of a type of protein to distribute within the colony that ...

Molecular Force Sensors

21-Sep-2017

Proteins are often considered as molecular machines. To understand how they work, it is not enough to visualize the involved proteins under the microscope. Wherever machines are at work mechanical forces occur, which in turn influence biological processes. These extremely small intracellular ...
