This interactive tutorial explores and compares the differences between specimens when viewed in a confocal versus a widefield fluorescence microscope. In this collection of digital movies, observe the activities of microscopic organisms taken from a typical North Florida pond.
Koch snowflake Quasi self-similarity: Hoffman Modulation Contrast Gallery - The modulation contrast technique takes advantage of optical phase gradients to yield a pseudo three-dimensional effect Images of nature images seen in the microscope.
The wide field of view and variable magnification displayed by stereomicroscopes is also useful for construction of miniature industrial Images of nature, or for biological research that requires careful manipulation of delicate and sensitive living organisms.
Most cells are far too small to be seen with the naked eye and require the use of high-power optical and electron microscopes for careful examination. Liquids have characteristics that fall in between gases and solids. This interactive tutorial explores various combinations of fluorescent proteins as potential FRET partners and provides information about critical resonance energy transfer parameters, as well as suggestions for microscope optical filter and light source configuration.
Irregularity locally and globally that is not easily described in traditional Euclidean geometric language. Polarized Light Microscopy Digital Image Gallery - As a contrast-enhancing optical technique, polarized light microscopy is unsurpassed in the magnificent array of colors and beautiful textures generated through interference between orthogonal wavefronts at the analyzer.
Multiphoton Excitation Microscopy - Multiphoton fluorescence microscopy is a powerful research tool that combines the advanced optical techniques of laser scanning microscopy with long wavelength multiphoton fluorescence excitation to capture high-resolution, three-dimensional images of specimens tagged with highly specific fluorophores.
Fractal patterns have been reconstructed in physical 3-dimensional space : God of Thunder - Probably the best silicon artwork we have yet seen, this image was discovered on a Hewlett-Packard graphics chip.
They are often forced to assume an awkward work posture such as the head bent over the eye tubes, the upper part of the body bent forward, the hand reaching high up for a focusing control, or with the wrists bent in an unnatural position. Confocal Microscopy Digital Image Gallery - Scroll through serial optical sections from a wide variety of specimens, including tissue culture cells, thin and thick sections, and entire organisms, in this Java-powered image gallery.
Extensive mutagenesis efforts in the original jellyfish protein have resulted in new fluorescent probes that range in color from blue to yellow and are some of the most widely used in vivo reporter molecules in biological research.
This cinemicrographic collection presents time-lapse movies of various chemical compounds as they change physical states.
Beneath the placid surface of any pond is a microscopic metropolis bustling with activity as tiny bizarre organisms pursue their lives; locomoting, eating, trying not to be eaten, excreting, and reproducing.
Requires the RealPlayer browser plug-in. Electrophoresis - Explore how electrical potential can cause migration and separation of macromolecules according to size in a cross-linked gel.
This fluorescence image gallery explores over 30 of the most common cell lines, labeled with a variety of fluorophores using both traditional staining methods as well as immunofluorescence techniques.
Basic Properties of Digital Images - Continuous-tone images are produced by analog optical and electronic devices, which accurately record image data by several methods, such as a sequence of electrical signal fluctuations or changes in the chemical nature of a film emulsion that vary continuously over all dimensions of the image.
Astigmatism - Astigmatism aberrations are similar to comatic aberrations, however these artifacts are not as sensitive to aperture size and depend more strongly on the oblique angle of the light beam.
In Octoberresearchers succeeded in cloning two laboratory rats by the problematic technique of nuclear transfer. The dropdown menus at the top of this page take you to the place you choose within that continent. Shortly after synthesis, most fluorescent proteins slowly mature through a multi-step process that consists of folding, initial fluorophore ring cyclization, and subsequent modifications of the fluorophore.
Of these two, non-destructive magnets are more suited towards scientific research, as they can reach some of the highest magnetic fields experimentally possible.A collection of amazing space pictures featuring images from the Hubble telescope and time lapse photos of the night sky.
