Chemical Synapse Under Electron Microscope
Using electron microscopy in the 1950s, Sanford L. Palay and George E. Palade clearly visualized synapses as specialized junctions between neurons. This confirmed how neurons communicate.
The Third Man Of The Double Helix
Maurice Wilkins
Wilkins used X-ray diffraction techniques to study DNA fibers. His work at King's College London helped provide crucial evidence that DNA had a helical structure.
Images From The Electron
Electron microscopy uses a beam of electrons instead of visible light to produce highly magnified images of very small structures such as cells, organelles, viruses, and materials at the nanometer scale.
Blast From The Past: Electron
The electron is generally considered to have been discovered on 30 April 1897, when J. J. Thomson announced his results at the Royal Institution in London, showing that cathode rays were negatively charged particles smaller than atoms.
