Just wanted to leave a note on two new cool gadgets that I found online.
The first one is a homemade electron microscope. An electron microscope is a type of microscope that uses electrons instead of regular light to illuminate and create images with better resolution. Kudos to Ben Krasnow for it.
The second one is a 3D printer that can be used to print biological organs. Organovo has figured out how to use 3D rapid prototyping to print blood vessels. But who knows if in the future they will be able to print full organs?
