They work differently to TEMs and SEMs too: they have an extremely sharp metallic probe that scans back and forth across the surface of the specimen. As it does so, electrons try to wriggle out of the specimen and jump across the gap, into the probe, by an unusual quantum phenomenon ...
How Does a Microscope Work? - ElectronAs previously mentioned, optical microscopes are limited in resolution by the frequency of the light waves. Electron guns emit a flow of electrons of a considerably shorter wave length than visible light and this fact allows an electron microscope to have ...

Technology:Scanning Electron Microscopy Share this Article: A scanning electron microscope (SEM) is a powerful scientific instrument used for high-resolution imaging and surface elemental analysis. They work by scanning a focused beam of electrons across the sample’s surface and detecting the resulting...
Light microscopes can reveal the structures of living cells and tissues, as well as of non-living samples such as rocks and semiconductors. Microscopes can be simple or complex in design, and some can do more than one type of microscopy, each of which reveals slightly different information. Th...
bacteria and yeast can all be seen using a compound microscope. Comparing these organisms helps students learn about the variety of life on Earth. Also, the way in which microscopes work can be used to teach students about the properties of light, the physics behind lenses and mirrors and sta...

Monosson does not mention insect or insect-inspired robots specifically but she does wonder if life/AI can evolve from wires and plastic. Considering all the work that is being done on insect-inspired robots I assume that we will soon find out. ...
The DishBrain system can send and receive electrophysiological signals to and from living neurons, training the cells to accomplish a task.
The need to limit antibiotic therapy due to the spreading resistance of pathogenic microorganisms to these medicinal substances stimulates research on new therapeutic agents, including the treatment and prevention of animal diseases. This is one of the g
