Live Coverage: On the Scene at NSH
Today is the second day of the 36th Annual National Society for Histotechnology Symposium/Convention in Seattle.
I am beginning my first full day in Seattle with a raspberry mocha from the Washington State Convention and Trade Center, and a presentation on Transmission Electron Microscopy in the Diagnostic and Research Laboratory.
Clive Wells, director Electron Microscopy Core Facility; and Mark Sadowski, HT(ASCP), pathology department, Medical College of Wisconsin, Milwaukee, are presenting the session.
Wells traced the history of electron microscopy back to Joseph J. Thompson, who discovered the electron through research in Cambridge and England back in 1897.
Thompson experimented with cathode ray tubes, discovered the electron and ushered in the atomic age, an accomplishment for which he was awarded the Nobel Prize.
Wells also covered the history of and differences between transmission electron microscopes and scanning electron microscopes; and the four main categories of microscopy:
- composition, and
- crystallographic information.
No matter what methodology or equipment you are using, Wells stressed the important aspect of electron microscopy is not magnification size, but resolution. He explicated his point with a cartoon depicting cave men looking through a giant microscope to identify a whole animal, declaring "It's a mammoth."
