Diffraction Limit, Microscopy, and Cell Biology | Eric Betzig on Super-Resolution Microscopy

What does a cell actually look like when you can see its molecules in action? In this episode, we speak with Nobel Prize-winning scientist Eric Betzig, whose pioneering work in super-resolution microscopy transformed our ability to see inside living cells. Betzig recounts his decades-long effort to overcome the diffraction limit of light microscopy, from…

Notes

  1. Why Did Eric Betzig Pivot From Super-resolution?

    at 15:15 · Transcript

    Eric Betzig pivoted from super-resolution because chemical fixation makes nanoscale structure artificial. Regular optical resolution can tolerate the damage. Full answer

  2. Why Did Eric Betzig Leave Science for His Dad?

    at 34:53 · Transcript

    Eric Betzig says the scales fell off his eyes early. He did not just leave Bell Labs, and he did not just leave Nearfield. Full answer

  3. How Did Eric Betzig See Single Molecules?

    at 40:01 · Transcript

    Eric Betzig says one of the two experiments he did at Bell, which led to the idea for the Nobel Prize, made him the first person to see single molecules at… Full answer

  4. Why Did Eric Betzig's Part Inspector Get Turned Off?

    at 43:44 · Transcript

    Eric Betzig built an inspector with about 30 cheap CCD cameras set all around a part. Full answer

  5. Why Did Eric Betzig Leave His Father's Company?

    at 54:17 · Transcript

    Eric Betzig says he is a good scientist, a horrible businessman, and an even worse salesman. He cannot make people feel comfortable. Full answer

  6. How Fast Did Bell Labs Flip From Papers to Fruit?

    at 1:17:27 · Transcript

    Eric Betzig hated science and hated academia, then realized he missed doing science and wanted a way back. Full answer

  7. How Did Eric Betzig Get the Science Data So Fast?

    at 1:29:47 · Transcript

    Eric Betzig says the method was obvious the moment violet light switched the molecules on. He and the other experimenter knew it worked, then raced. Full answer

  8. Why Did Eric Betzig Call the 2014 Nobel Premature?

    at 1:34:11 · Transcript

    Eric Betzig argues that most single-molecule super-resolution has not revealed much of anything, and that most super-resolution in general has not either. Full answer

  9. What Comes First From Eric Betzig's Cell Observatory?

    at 1:54:42 · Transcript

    Eric Betzig says the first thing from the cell observatory is robust segmentation, and segmentation would be valuable in many contexts. Full answer

  10. How Fast Does Eric Betzig Need Microscope Data?

    at 2:10:45 · Transcript

    Eric Betzig says microscopes get better all the time, and he keeps an ear out for anything new that comes along. Full answer

  11. Why Can't Dyes Show a Thousand Proteins at Once?

    at 2:13:19 · Transcript

    Eric Betzig says a label with a truly narrow emission line would let a microscope watch a thousand proteins at once, because each spectrum would stay narrow. Full answer

  12. Why Does Eric Betzig Say Nuclear Beats Wind and Solar?

    at 2:15:45 · Transcript

    Eric Betzig says the right long-term answer on energy is nuclear, and he has no doubt about it. Nuclear will be scalable. Full answer

  13. Why Did Bell Labs Line Every Lab Down One Hall?

    at 2:24:19 · Transcript

    Eric Betzig says Bell Labs turned out 12 Nobel Prizes from one institution because scientists were left to do science all the time. Shannon worked that way. Full answer

  14. Why Does Eric Betzig Call Bell Labs Impossible to Copy?

    at 2:28:59 · Transcript

    Eric Betzig says copying Bell Labs is literally impossible. Full immersion is an immutable law of how the human brain works. Full answer

  15. Why Does Eric Betzig Call Biology the Last Frontier?

    at 2:38:31 · Transcript

    Eric Betzig says biology is the last frontier. He studies it at the last stage of his career and says he is never going to be a biologist. Full answer
