To use a light microscope to examine animal or plant cells. To make observations and draw scale diagrams of cells. Turn the coarse focus so that the stage is as close to the objective lens as possible ...

Let's take a look at how to observe cells under a microscope. No prizes for guessing the first thing you'll need: a microscope. But don't worry if you don't have one of your own. Ask your school if ...

Our window into the cellular world just got a whole lot clearer. By combining two imaging technologies, scientists can now watch in unprecedented 3-D detail as cancer cells crawl, spinal nerve ...

What does the inside of a cell really look like? In the past, standard microscopes were limited in how well they could answer this question. Now, researchers from the Universities of Göttingen and ...

Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...

Using a tiny, spherical glass lens sandwiched between two brass plates, the 17th century Dutch microscopist Antonie van Leeuwenhoek was the first to officially describe red blood cells and sperm cells ...

Unlike traditional microscopes, which use light, the new approach uses DNA 'bar codes' to label each molecule in the cell. From readings of the complex interactions of these labels with the molecules ...

Researchers at Helmholtz Munich and the Technical University of Munich have developed a new microscope that significantly improves how bioluminescent signals in living cells can be observed. The ...

The polarized diSPIM microscope, which can image full 3D orientation and position of molecules in cells. The instrument was constructed in the Hari Shroff lab at the National Institute of Biomedical ...

Throughout history, humans have endeavoured to see things that were too small to be perceived with the naked eye in order to understand our complex world. The first magnifier constructed for ...

Brazilian scientists have been studying how the coronavirus spreads and captured images of it infecting healthy cells under a powerful electron microscope. The telescope magnifies objects up to two ...

Medical engineers have developed a hand-held microscope that can differentiate cancerous cells from healthy ones much faster than pathology labs Dennis Wise/University of Washington Medical engineers ...
