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 ...

Rules of resistance against transgene silencing

Clear rules for engineering transgenes that can be inserted and propagated over multiple generations of nematodes include ways to protect inserted genes from the organism's natural defenses against foreign DNA. Developed ...

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.

The tips of a plant design its whole shape

Plants grow throughout their entire life. This is due to a small structure at the tip of the plant's shoots known as the meristem. This is the control center for the maintenance of stem cells—which can be converted into ...
