Cytobots – cyborg bacteria

American biotechnologists turned the bacterium into a kind of cyborg, which they called a nano-electronic robo-device and a "cytobot" and taught it to work as an ultra-sensitive humidity sensor.

Bandage against bleeding and infection

The new dressing quickly releases thrombin, stopping bleeding. Then, within a few days, he secretes vancomycin to prevent infection of the wound. The "bandage" of biocompatible polymers also dissolves.

Laboratory on a smartphone: premature delight?

The specificity of the experimental technique was 79%. Simply put, every fifth result was erroneous. This is already better than fortune-telling, but it is still very far from the requirements of medical standards.
