Boris Johnson visits The Francis Crick Institute

The video tutorial covers the use of microscopes in a vacuum, the process of embedding samples in resin, and the importance of using model systems like zebra fish embryos for efficient research. It explains the technique of using diamond knives to cut extremely thin slices for microscopy and highlights the significance of magnetic scanning in analyzing larger molecules. The tutorial emphasizes the careful handling of expensive equipment and the benefits of advanced microscopy techniques in scientific research.

Why is it important to use plastic resin instead of ice for preserving samples in microscopy?

• Plastic resin prevents samples from exploding under pressure.

• Plastic resin is more transparent than ice.

• Ice is too expensive.

• Ice can damage the microscope.

What makes zebrafish embryos suitable for developmental biology studies?

• They grow quickly.

• They are transparent.

• They are easy to catch.

• They are very large.

Why is a diamond knife used for slicing samples in microscopy?

• It is easier to handle.

• It is very sharp and can cut extremely thin slices.

• It is cheaper than other knives.

• It is more durable than other materials.

What is the main advantage of using strong magnets in microscopy?

• They can be used in any environment.

• They are less expensive.

• They allow for faster results.

• They are easier to maintain.

What is the purpose of magnetic scanning in microscopy?

• To reduce the cost of microscopy.

• To increase the size of the samples.

• To scan the nucleus magnetically.

• To enhance the color of the samples.
