Cambridge University's Under the Microscope is a collection of videos that show glimpses of the natural and man-made world in stunning close-up. Check out the rest of the series here: bit.ly In this video we see a killer T cell of the immune system attacking a cancer cell. Professor Gillian Griffiths: "Cells of the immune system protect the body against pathogens. If cells in our bodies are infected by viruses, or become cancerous, then killer cells of the immune system identify and destroy the affected cells. Cytotoxic T cells are very precise and efficient killers. They are able to destroy infected or cancerous cells, without destroying healthy cells surrounding them. The Wellcome Trust funded laboratory of Professor Gillian Griffiths, at the Cambridge Institute for Medical Research, investigates just how this is accomplished. By understanding how this works, we can develop ways to control killer cells. This will allow us to find ways to improve cancer therapies, and ameliorate autoimmune diseases caused when killer cells run amok and attack healthy cells in our bodies." Cytotoxic T cells are just 10 microns in length: approximately one-tenth the width of a human hair. These movies are 92 times real time. The original footage shown was made by Alex Ritter, a PhD student on the NIH-OxCam programme, in the laboratory of Professor Gillian Griffiths at the Cambridge Institute for Medical Research and the Department of Medicine of the Clinical School of the University of <b>...</b>

Today, I finally produced an image with my DIY scanning electron microscope. I've spent the last few months working on this project, and am encouraged by today's success. There is still a lot of work left to do in making the image higher resolution, and eliminating sources of noise, however this image proves that all parts of the microscope are operating as designed. I will be showing this project at Maker Faire 2011 in San Mateo.

Amoeba on microscope slide, slinks slowly across. Amoeba (sometimes amœba or ameba, plural amoebae) is a genus of Protozoa. The cell's organelles and cytoplasm are enclosed by a cell membrane, obtaining its food through phagocytosis. Amoebae have a single large tubular pseudopod at the anterior end, and several secondary ones branching to the sides. The most famous species, Amoeba proteus, averages about 220-740 μm in length while moving, making it a giant among amoeboids. A few amoeboids belonging to different genera can grow larger, however, such as Gromia, Pelomyxa, and Chaos. Amoebae's most recognizable features include one or more nuclei and a simple contractile vacuole to maintain osmotic equilibrium. Food enveloped by the amoeba is stored and digested in vacuoles. Amoebae, like other single-celled eukaryotic organisms, reproduce asexually via mitosis and cytokinesis, not to be confused with binary fission, which is how prokaryotes (bacteria) reproduce. In cases where the amoeba are forcibly divided, the portion that retains the nucleus will survive and form a new cell and cytoplasm, while the other portion dies. Amoebae also have no definite shape.

The multitouch microscope brings new dimensions into teaching and research. Researchers at the Institute for Molecular Medicine Finland (FIMM) and Multitouch Ltd have created a hand and finger gesture controlled microscope. The method is a combination between two technologies: web-based virtual microscopy and a giant size multitouch display. The result is an entirely new way of performing microscopy: by touching a table- or wall-sized screen the user can navigate and zoom within a microscope sample in the same way as in a conventional microscope. Using the touch control it is possible to move from the natural size of the sample to a 1000-fold magnification, at which cells and even subcellular details can be seen.

The dedicated recording microscope or 'opto-torinex' was first produced in Switzerland in 1866, by the scientist and entrepreneur LeClerk. The first models simply suspended a photographic plate above a converting lens fitted to a traditional microscope, but within two years more sophisticated versions were being produced. These used photographic film in a custom-built lens array and offered far greater clarity and detail. Originally designed to be used by medical professionals, the cost of these early units was so great that they were only purchased by royalty who used them to enhance detail on old pornographic postcards. (Information taken from Wikipedia.) [And if you're wondering - Silver Berry Scaly Hair is literally the scaly hair taken from the silverberry plant. I've known this for about 25 years as we looked it up in an encyclopaedia when I was given the microscope. But people don't read this text and will instead be saying what it is in the comments.

Fluorescence is a physical phenomenon in which a compound absorbs light and re-emits this as light of a usually higher wavelength. Since the wavelengths of the excitation light source and the emitted fluorescence can be separated very well, we can detect fluorescence with very high sensitivity, making it possible to visualize even single molecules. Many different fluorescent probes for cellular components have been developed, including genetically encoded probes like the Green Fluorescent Protein (GFP). For these reasons, fluorescence microscopy is a very powerful tool in Cell Biology research. See more at www.ibioseminars.org

Check us out at www.tutorvista.com A microscope is an instrument to see objects too small for the naked eye. The science of investigating small objects using such an instrument is called microscopy. Microscopic means invisible to the eye unless aided by a microscope Types of microscopes "Microscopes" can be separated into optical theory microscopes (Light microscope), electron microscopes (eg, TEM), and scanning probe microscopes (SPM). Optical microscopes function through the optical theory of lenses in order to magnify the image generated by the passage of a wave through the sample, or reflected by the sample. The waves used are electromagnetic (in optical microscopes) or electron beams (in electron microscopes). Types are the compound light, stereo, and the electronic microscope Optical microscopes, using visible wavelengths of light, are the simplest and most used. Optical microscopes have refractive glass and occasionally of plastic or quartz, to focus light into the eye or another light detector. Mirror-based optical microscopes operate in the same manner. Typical magnification of a light microscope, assuming visible range light, is up to 1500x with a theoretical resolution limit of around 0.2 micrometres or 200 nanometers. Specialized techniques (eg, scanning confocal microscopy, Vertico SMI) may exceed this magnification but the resolution is diffraction limited. The use of shorter wavelengths of light, such as the ultraviolet, is one way to improve the spatial <b>...</b>

In this video from, we see a mouse embryo developing. Erica Watson, Cambridge University, tells us that studying this process helps us better understand human pregnancy. Under the Microscope is a collection of videos produced by Cambridge University that show glimpses of the natural and man-made world in stunning close-up. You can see the whole series here: bit.ly Erica Watson: "The development of a fetus is elegant yet complex. Amazingly, most fetuses undergo a highly orchestrated sequence of events during development to produce a healthy baby. This suggests that a baby can adapt to changes in the womb, such as to the availability of nutrients from its mother. But how do these environmental changes affect the baby's health in later life? And is it possible that these adverse changes will alter the development of generations to follow? In other words, does the environment that a baby develops in affect its grandchildren's growth and development? Our research aims to understand these questions using a mouse model with a genetic mutation that prevents the normal breakdown folic acid (a vitamin). This mutation alters the metabolism of a mouse and causes long-lasting effects on the generations to come. Our hope is to find out how environmental changes caused by a genetic mutation are perpetuated into subsequent generations, even when these generations do not carry the mutation. Since humans and mice use similar genes during development, we can get valuable information from a <b>...</b>
