Anthony van Leeuwenhoek is credited with being the first person to observe microorganisms. He was a Dutch scientist who developed the first microscope capable of observing these tiny organisms. Through his observations, he discovered and described various microorganisms, including bacteria, protozoa, and...
Bacteria are much smaller than eukaryotic cells. They appear as dark rod-like structures, spheres or spiral structures under the microscope, and they may exist as single cells, in pairs, chains, or clusters. Bacteria can be visualized using phase contrast and 100x - 400x magnification. Phase ...
thick culture of bacteria, and it can't sustain that. And so what happens is, every morning when the sun comes up, the squid goes back to sleep, it buries itself in the sand, and it's got a pump that's attached to its circadian rhythm. And when the sun comes ...
An ordinary light microscope uses photons of light, which are equivalent to waves with a wavelength of roughly 400–700 nanometers. That's fine for studying something like a human hair, which is about 100 times bigger (50,000–100,000 nanometers in diameter). But what about a bacteria ...
And so, the question for my lab is whether you want to think about all the good things that bacteria do, or all the bad things that bacteria do. The question we had is how could they do anything at all? I mean they're incredibly small, you have to have a microscope to see one....

The final component of the gut-brain axis that needs to be addressed is the gut microbiome. Each person has a microscopic ecosystem in their intestines, hosting bacteria, fungi, and even viruses and parasites. These microorganisms are involved in the production of neurotransmitters that carry signal...
Dutch draper and microscope maker Antonie van Leeuwenhoek was also instrumental, being the first to describe sperm cells and bacteria in droplets of water. [Nature Under Glass: Gallery of Victorian Microscope Slides] Today's microscopes But modern microscopes have come a long way since the days ...
Deadly outbreaks have plagued societies for centuries. But they can lead to medical breakthroughs—if we learn the right lessons from them.
