A safer way to deploy bacteria as environmental sensors

In recent years, scientists have developed many strains of engineered bacteria that can be used as sensors to detect environmental contaminants such as heavy metals. If deployed in the natural environment, these sensors could ...

Strong signals show how proteins come and go

A novel system to amplify gene expression signals could be a game-changer for scientists who study the regulatory processes in cells that are central to all life.

Bacteria made to mimic cells, form communities

Rice University scientists have found a way to engineer a new kind of cell differentiation in bacteria, inspired by a naturally occurring process in stem cells.

Bacterial 'FM radio' developed

Programming living cells offers the prospect of harnessing sophisticated biological machinery for transformative applications in energy, agriculture, water remediation and medicine. Inspired by engineering, researchers in ...

A complex logic circuit made from bacterial genes

(Phys.org)—By force of habit we tend to assume computers are made of silicon, but there is actually no necessary connection between the machine and the material. All that an engineer needs to do to make a computer is to ...
