A microscope slide is a very thin piece of glass used to hold the object that is to be viewed. They usually have another smaller, very thin piece of glass called a coverslip which fits on top of the sample. Sometimes chemical stains are used to make sections of the cell easier to see....
The simplest microscope of all is a magnifying glass made from a single convex lens, which typically magnifies by about 5–10 times. Microscopes used in homes, schools, and professional laboratories are actually compound microscopes and use at least two lenses to produce a magnified image. There...
Depending what you have on hand, you may not even have to spend a dime to do it. Here's what you need: Two or three reflective surfaces. These might be small mirrors, glass slides (the type you would use under a microscope) with one side of each painted flat black, or reflective ...
Dry mount slides can consist of a sample placed on a slide or else a sample covered with a coverslip. For a low power microscope, such as a dissection scope, the size of the object isn't critical, since its surface will be examined. For a compound microscope, the sample needs to be ...
The usefulness of histological staining lies in its ability to reveal sub-cellular details of tissues. When a fresh tissue section is prepared in the laboratory without staining, then the images recorded with a conventional microscope using basic illumination lack the necessary contrast needed to rev...
When growing with Ruderalis-based cannabis strains such as the Lowryder, you can give the plant up to 18 hours of light a day for the whole grow, and your plant will be ready to harvest in about 3 months. Because of their short lifecycle, Ruderalis cannabis stains generally do not grow...
Why do microbes produce chemicals that are inhibitory to other microbes? Do acinar cells make bile? How do mucous membranes help fight pathogens? White blood cells engulf bacteria through what process? What color do stained Gram-positive bacteria appear under the microscope?
Pretrained neural network models for biological segmentation can provide good out-of-the-box results for many image types. However, such models do not allow users to adapt the segmentation style to their specific needs and can perform suboptimally for te
U2OS cells were labelled with two different fluorescence stains marking the same structure, WGA-Alexa488 and WGA-Alexa555 which both bind to cellular membranes. By acquiring both channels in Mica sequential mode, this experimental setup ...
There are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise...
