What is Dutch elm disease (DED)? A deadly fungal disease that infects elm trees and stops water from flowing through their vessels, causing them to wilt and die. The main cause is Ophiostoma ulmi and Ophiostoma novo-ulmi. Dutch phytopathologists Schwarz and Buisman found it in the Netherlands in the early 1920s. It was brought to … Read more
What is Fusarium Wilt? Fusarium wilt is a prevalent soil-borne fungal affliction produced by Fusarium oxysporum, affecting various plants such as tomatoes, bananas, cucumbers, and beans, resulting in progressive wilting and eventual plant mortality. Causative Agent of Fusarium Wilt Primary causal organism – Fusarium oxysporum is the dominant species responsible for Fusarium wilt across diverse … Read more
What is Electroporation? Electroporation is a fascinating technique that temporarily makes cell membranes more permeable by applying brief electric pulses. This method, widely used in labs and medical settings, allows substances like DNA, drugs, or proteins to enter cells by creating tiny pores in the membrane. Imagine zapping cells with a controlled jolt of electricity—this … Read more
What is Fine Adjustment Knob? Particularly in high magnification levels, the fine adjustment knob is an essential part of a microscope as it helps to achieve exact and crisp focus. Particularly in the study of cells, microscopes are essential instruments in scientific inquiry as they let us view objects beyond our human sight. Under a … Read more
It is designed in a way that is compact and portable which is why it’s called a pocket’. They’re pocket-sized however some are bigger. Their size is not enough to be able to hold a mirror in order to put the image in the proper place. However, they contain a small stage where one can place an object to observe. They’re portable so that they can be utilized by both professionals and amateurs according to the task they’re designed to fulfill.
What is Polarizing Microscope? A polarizing microscope is an optical microscope that allows one to see birefringent materials—materials that give off two rays of light moving at varying speeds and indices of refraction—and contains certain added components for enhanced viewing contrast and more precise structural detail. As for the components of the microscope procedure that … Read more
What is transmission electron microscope? A transmission electron microscope (TEM) is an electron microscope that transmits electrons through a sample to observe it. Scientists use transmission electron microscopes to analyze materials and examine their microstructural and compositional properties. A transmission electron microscope transmits a highly focused beam of electrons through a sample to observe and … Read more
This reflects the seemingly marvelous developments that have occurred from the history of microbiology to the present day. Advances in technology and subsequent research in the field over the years have meant that once we learned how to study these tiny creatures, we only grew in appreciation for these vital little agents. But in 1590, … Read more
What is Inverted Fluorescent Microscope? Ever peeked into the world of living cells? Scientists use a nifty tool called an inverted fluorescent microscope for this. Unlike regular microscopes, this one flips the script—literally. Imagine the lenses sitting above the sample and the light source shining from below. This upside-down setup makes it perfect for studying cells chilling at the bottom … Read more
What is an Inverted Microscope? An inverted microscope is literally an inverted microscope. The lights and lenses are positioned above the specimen stage and the objective lenses are below. This allows the user to critically observe the samples from below; this is important because many living specimens and cells to be observed are in petri … Read more
