Zhuang begins her lecture by explaining that the resolution of traditional light microscopy is about 200 nm due to the diffraction of light. This diffraction limit has long hampered the ability of scientists to visualize individual proteins and sub-cellular structures. The recent development of sub-diffraction limit, or super resolution, microscopy techniques, such as STORM, allows scientists to obtain beautiful images of individual labeled proteins in live cells. In Part 2 of her talk, Zhuang gives two examples of how her lab has used STORM; first to study the chromosome organization of E. coli and second, to determine the molecular architecture of a synapse.

Cool! She is a very highly regarded scientist, and helped create a nobel prize winning technology. Many people think she should have been awarded as well, but it is limited to 3 people and hard to choose which are most deserving.

Thanks for breaking this down so simply. It is amazing just how detailed the images are and humbling to realize that each of the cells imaged are so vastly complex and compact. Exciting to imagine how much further this can be improved. Thanks again I really felt like I learned a lot.

This video is exactly what I was looking for. I had trouble to understand super resolution microscopy, and now I think I understood the core concept of it. Thank you so much!!

I am only 6 minutes in and already I approve of your presentation. I am a layperson who studies the sciences purely for self enlightenment. Unfortunately I was unable to pursue my passion for a science career in my youth due to financial issues. Nicely done and very informative.

(On Monday of April 17, 2023). On the Matter of PhD Xiaowei Zhuang from Howard Hughes Medical Institute and Harvard University (Boston, MA) on the Topic of Super-Resolution Fluorescence Microscopy and the Biophysics (Sub-Diffraction Limit) of Light Microscopy: 1) Monoclonal Antibodies or Chemotherapeutic Drugs are quite Limited in Specificity And In Part has to do with the Inability to Test and Verify the Pharmaceutical Claims which usually go completely uncontested as long as FDA Clinical Procedure has been even lethargically Exercised at the Risk and almost always fulfilled to Ineffective and Very costly Therapeutics. Even Methotrexate, An Antifolate Drug and Mechanism therein could use specification and Reaction times of Binding because the Finesse of the Antagonism is what would be more of Benefit than the mere--frankly ineffective--Gross and Crass narration/Effect of Cytotoxicity. Anyway, the Imaging of Fluorescence (STORM, PALM et al) has its limits but certainly a vast amount of Proteomics can be and has been understood or investigated. My personal favorite is the Metabolism Visualization of the Voracious and Dysregulated Rate of Reproduction via Hyperactive NTP Biosynthesis, I mean its Entropy at its best, and it has been Elucidated by this Modality of Microscopy Fairly. 2) The Embryology and Dysgenesis or Aplasia Therein is a rather nice manner to Understand and Highly likely to be of vast benefit In the Effort to Prevent such Lamentable and Often Detrimental Metabolic Recessive Diseases (Incidence and Prevalence Management is not a Legitimate CDC Function) where a Defective Protein is Post Facto understood rather than before its Formation and Proteogenic Defect Manifests Pathology. Perhaps also the Methylome of DNA (Protein and Nucleic Acid Visualization) could be in Vivo Tagged and be of Diagnostic/Therapeutic value, especially in favor of Prophylaxis of pathology rather than to blindly, scientific professionals' most flagrant misgiving to Mankind, see the effect, or even more, most disgustingly, to Palliate. 3) In Short, I am glad this Technology is Available and Disseminatable because another distressing Parameter in Pure Science and Research And Investigations Currently is its Political and National Security Factor. There is never a Winner in this Scenario even the Morbidly and Moribund Industrial Complex of Death and Destruction. This is currently my upmost concern because Progress is dependent obviously in the Pursuit of Profit and War while a time Before it was a Matter of Emancipation and Cultivation. We can all forget this bodacious Revery if the known tyrannical Procedures continue and even Prosper. PhD Zhuang, es geht gut aber es muss sollten gehabt schnelller sein. Heil!

for cryonicists we will need more than that, more than 10 NM resolution, and not only cells outsides the bodies, but inside the bodies like in a MRI, while the patient is living or not, like frozen or where there are movement. This tool was implemented in 2006 I think or so, and perfected in 2018 or 2016. Let's put another 100 years and we will be able to see in a resolution of less than 1 nanometers, everywhere inside living bodies or objects with movements inside. we will need scanners of 0.1 nm of resolutions for living patients.

It will be good for cryonicists and I have the same disease than Howard Hughes almost. But I hope this tool will widely be used by scientists in the future to see if we can save our own lives. like in anti aging. all around the world. in germany, in france, in china, in canada, in usa etc..

We weren't filming in HD at the time we recorded the talk. However, check out www.ibiology.org/ibioeducation/taking-courses/ibiology-microscopy-short-course/super-resolution-microscopy.html and the videos here www.ibiology.org/ibioeducation/taking-courses/ibiology-microscopy-course.html as most of them were in HD.

Isn't that all Green Screen that you are doing? Couldn't the background be incorporated at a higher resolution and the video rerendered at 720p or 1080p? I realize that the foreground lecturer will not be in HD, which may look a bit weird, but the important images in data will be more clear.
