An army of microrobots can wipe out dental plaque

A swarm of microrobots, directed by magnets, can break apart and remove dental biofilm, or plaque, from a tooth, thanks to a partnership led by Dental Medicine’s Hyun (Michel) Koo and Engineering’s Edward Steager.

In this image, the researchers labeled new proteins white, and antibodies against other proteins in a different color. The co-localization of new proteins and antibodies show how cells can impact their local environments. (Photo: Penn Engineering)

Cells control their own fate by manipulating their environment

Muscle, blood, brain, and skin cells are different from one another, but they all share the same DNA. Stem cells’ transformation into specialized cells is controlled through various signals from their surroundings. A study suggests that cells may have more control over their fate than previously thought.
