Maybe it expressed a sergeant’s snark toward the officer corps. Or a budding scientist’s thrill at a big find. Either way, the hand-lettered label that future Bates professor William H. Sawyer Jr.

The researchers dubbed the individual cells "microscopic tornadoes" for their rapid rotation, which both forms the crystals by drawing in other cells and then powers the crystals' own motion. Insects ...

Then, slides were prepared by placing a drop of blood on a glass slide and stained with dye to make the bacterial cell structures more visible. Next, they trained a convolutional neural network (CNN) ...

COLUMBUS, Ohio -- Researchers are studying some common soil bacteria that "inhale" toxic metals and "exhale" them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals ...
