Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...

Modeling how cells choose their fates

It may seem hard to believe, but each one of us began as a single cell that proliferated into the trillions of cells that make up our bodies. Though each of our cells has the exact same genetic information, each also performs ...

Psychological understanding of the term 'artificial'

Is natural always good and artificial always bad? We talked to psychologist Angela Bearth and biotechnologist Sven Panke about science, skepticism, misunderstandings and how language influences the way we think.

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 ...
