Gram-positive bacteria are bacteria that contain a thick cell wall. During the Gram staining process — a test that experts use to view the bacteria under a microscope — they appear purple or blue.

Prochlorococcus bacteria are so small that you’d have to line up around a thousand of them to match the thickness of a human thumbnail. The ocean seethes with them: The microbes are likely the most ...

But when the scientists looked under the microscope, they found the DNA and ribosomes clustered together in many tiny pockets, each surrounded by a membrane. No free-wheeling genetic information here.

The molecule can then be tracked under an ordinary – albeit very high-resolution – optical microscope. Cryo-ET uses electron microscopes to study flash-frozen samples, like cells.

The bacterial cell wall maintains the shape and integrity of unicellular organisms. ... Fluorescent proteins in Staphylococcus aureus under the microscope.

Viewing these masses under a microscope revealed a surprise: they appeared to be capable of complex motion. Small bacterial cells tended to cluster around the core of each clump, forming a sticky ...
