3D Microscopes: To boldy go…

TL;DR

Researchers are now able to observe sub-cellular details and explore cellular processes in a more natural setting using advanced microscopes, leading to unprecedented insights and the ability to generate new hypotheses for scientific exploration.

Transcript

This the miracle of being able to see what was not being able to see before. More like Star Trek, right? It's the age of exploration again. It's simply incredible. So we biologists like to see how things occur and we like to see a cell. We like see the interior of a cell. Cells didn't evolve on a cover slip. Cells didn't evolve in isolation. So we ...

Questions & Answers

Q: What were the two brilliant thoughts of Eric Betzig, the inventor of these microscopes?

Eric Betzig's first breakthrough was creating a form of microscopy that minimizes damage to samples by scanning a thin layer of light. His second innovation was borrowing techniques from astronomers to de-blur perturbations and enhance image clarity.

Q: What is one mind-blowing observation enabled by these microscopes?

Researchers have been able to observe a neutrophil crawling through the ear of a zebrafish and eating injected food particles, providing an incredible insight into cellular behavior in live organisms.

Q: What unique insight into cancer cells has been gained using these microscopes?

By implanting human cancer cells in zebrafish, researchers have been able to observe the cells moving along capillaries, crossing their walls, and even sending pieces of the cell to explore their surroundings, allowing for a better understanding of cancer cell behavior.

Q: What is the significance of mapping the entire eye of a zebrafish with these microscopes?

By computationally exploding the cells and observing their changes in morphology in the context of the tissue, researchers can study the dynamics of intracellular compartments and gain insights into the development and function of the eye.
