Scientists used patterned plastic surfaces to trick bacteria into halting their own spread. These designs may prevent ...

The accumulation of microplastics in the environment, and within our bodies, is an increasingly worrisome issue. But predicting where these ubiquitous particles will accumulate, and therefore ...

Most people have encountered the black, gray, or pink stains of bacterial biofilms built up on the bathroom tiles or kitchen sink. Even with vigorous scrubbing and strong cleaning chemicals, this ...

Gene expression changed. So did the makeup of the biofilm’s sticky extracellular matrix and the physical arrangement of its cells. Dietrich and colleagues published their results in PLOS Biology in ...

It's never a good thing, when a bacterial biofilm forms on the surface of a medical implant. There could soon be a new way of eradicating such films, however, using tiny remote-control liquid ...

Bone breakdown, muscle loss: What nine months in space does to the body After an unplanned nine-month stay in space, astronauts Barry Wilmore and Sunita Williams have returned to Earth.

Of these substances, 3601 (25%) were found in human body samples. The researchers have made their list available to the public for free. For each substance, they have provided references to ...

If you used their density to estimate the cells in a human body, you’d come to a staggering 724 trillion cells. Skin cells, on the other hand, are so sparse that they’d give you a paltry ...
