For most of human history, the atom was a philosophical concept — matter’s smallest theorized unit, invisible by definition. That changed in 1931, when a pair of German scientists aimed a beam of electrons at a thin specimen and produced an image no light microscope could ever rival. Today, we don’t just see atoms; we …
Have you ever wondered what head lice look like under the microscope would look like? After discussing dandruff, we proceed to a more perplexing organism that preys on a child’s hair – the head lice. Observing head louse, louse eggs, and even adult lice under the microscope requires caution and knowledge on properly observing them. …
Observing sperm cells under a microscope is another interesting experiment to conduct. Analyzing sperm can give information about the reproductive function of a male patient. Observing sperm cells is also part of a routine semen analysis and is done to identify issues with the male reproductive cells. An observer can come up with normal sperm …
Observing blood cells under the microscope is often part of the medical analysis to find any abnormalities in the structure of the blood. The process is called blood smear or hematology analysis. Often, doctors would request for complete blood count to check the disparity of the red blood cell, white blood cells and get the …
Grass under the microscope reveals a world of geometric precision that most people walk over every day without suspecting. Mount a fresh blade of lawn grass, bring it into focus at 40×, and the first thing that snaps into view is a neat row of oval vascular bundles running the length of the leaf — …
Worms under a microscope reveal a world far stranger and more detailed than a garden shovel ever shows: transparent organs pulsing with fluid, hair-like setae gripping a glass slide, and embryos assembling cell by cell inside a living body. Three completely unrelated groups — segmented annelids, flat platyhelminthes, and cylindrical nematodes — all carry the …
If you’re looking for the best microscope for kids, there are tons of different options on the market. But, you can’t just settle on the first one you see, or the cheapest model you come across.

For many of us, our introduction to the wonderful world of microscopy starts in school- specifically, the science lab. And, if you’re like me who had an amazing experience learning about tiny organisms, insects, crystalline structures, and the like, you probably don’t want the fun to end once you leave the campus. Want to find …
A wireless digital microscope for iPhone connects to your phone over its own WiFi hotspot, letting you view magnified images of coins, circuit boards, skin, or insects directly on your screen without a cable or adapter. These handheld units trade the bulk of a benchtop microscope for pocket-sized convenience, making them popular with hobbyists, collectors, …
Cork cells are the reason the word “cell” exists in biology at all. When Robert Hooke pressed a sliver of cork against his primitive microscope lens in 1665, he saw rows of empty, walled compartments so uniform they reminded him of the tiny rooms — cellae — in a monastery. He drew them, named them, …
