This was done on cells in a lab, not in people. It is a very early step.
This is a new lab tool, tried only on tissue samples.
The short version
Scientists built a tool that photographs brain tissue clearly without using any stains or dyes.
What was studied. Researchers built a new microscope that uses four small scanning units at once. They tried it out on mouse brain tissue and on human glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are given a grade from 1 to 4 describing how the tumor is expected to behave. See the glossary tissue.
What they found. The tool took sharp pictures of a tissue piece 13 x 13 mm2 in size. It finished the whole picture in 100 seconds. Tools like this usually see an area less than a millimeter wide, so this covers much more ground.
What this means, and what it doesn't
What it could mean: This does not change anything about your care today. The hope is that one day surgeons could check tissue right in the operating room. That might cut the wait for lab results, but that has not been tested yet.
What it doesn't mean: This is not a treatment, and it is not a cure. It is a new lab tool, tried only on tissue samples, not on people in surgery. Nobody has shown it helps patients live longer or feel better. Much more testing would be needed before any hospital could use it.
