| DNA Animation Applet |
|
This DNA animation applet demonstrates a genome project. The circle containing 8 daughter forms (spore) is the cyst. One spore escapes the cyst. Coming out of the existing spore are the chromosomes of the organism represented by rectangles. Then the leading rectangle allows the DNA alpha helix to escape.

| Scanning Electron Microscopy |
|
We have teamed up with award-winning electron microscopist Dennis Kunkel to produce a virtual Scanning Electron Microscope (vSEM). Visitors can adjust the focus, contrast, and magnification of microscopic creatures viewed at thousands of times their actual size.

| Biomorph Breeder |
|
This applet lets you experiment with breeding artificial creatures called biomorphs, causing them to gradually evolve into a diversity of forms. The biomorphs start out as tree-like shapes, whose physical conformation is determined by 9 different genes, affecting things like the length and angle of branches, the color, etc.

| Basal Metabolism |
|
This applet calculates basal metabolism and nutritional needs given an individuals criteria (height, weight, activity rate, etc). The code was originally done as a teaching tool and later ported to Java because it makes a 'cool' little applet. Aside from folks finding it fun to have this 'health' type information calculated for them, this applet demostrates Java's current application download at run time and desktop interactivity.

| Fluorescence Microscopy with Multiple fluorochrome stains |
|
Fluorescence microscopy takes advantage of emission spectral properties of fluorochrome dyes used to specifically stain various portions of a specimen. This tutorial explores how samples stained with multiple fluorochrome stains appear when excitation illumination is filtered through various fluorescence cubes.

| Polarized Light Microscopy |
|
The tutorial simulates observation of various birefringent samples between crossed polarizers in a polarizing microscope. The virtual microscope stage is graduated in 10 degree increments and allows rotation through a full 360 degree turn of the sample. As the sample is rotated, birefringent elements of the sample undergo intensity changes (from brilliantly illuminated through total extinction) that reflect their orientation with respect to the virtual microscope polarizer and analyzer.

| Fluorescence Combination Microscopy |
|
This tutorial simulates the combination of fluorescence microscopy with either phase contrast or differential interference contrast (DIC) microscopy. The visitor can toggle between views of the various techniques separately or combined to produce increased contrast effects.

| AIDSGraph |
|
This applet provides a graphical interface to the CDC's database of AIDS cases in the United States. Different categories of the database can be extracted and graphed in various ways. This applet illustrates the characteristics of the AIDS epidemic.

| Differential Interference Contrast Microscopy (DIC) |
|
The DIC interactive Java tutorial explores how changes in the orientation of the polarizer in a Senarmont compensation system will affect image contrast. Visitors are able to adjust a slider that simulates rotation of the polarizer and are able to see how this rotation enhances sample contrast.

| Magnifying Microscopy |
|
This interactive Java tutorial explores the effect of increasing magnification (equivalent to changing microscope objectives) on the ability to resolve features in a sample. We provide actual size images of the sample so students can understand the dramatic increases in magnification of the samples they are examining. Each magnification is accompanied by a description of the features available at that resolution. Samples featured in this module include computer chips, Moon rocks, superconductors, and the surface of a Compact Disc.

| Bioethical Assessment Tool 3 |
|
This is an interactive java-based program which changes regularly. The goal is to pick the bioethical paradigm which will help you the most for the case fragment presented. Sometimes there isn't a 'perfect fit', just as in real life.

| Phase Contrast Microscopy |
|
Explore how phase plate alignment with respect to the objective phase ring affects specimen contrast in phase contrast microscopy. This tutorial allows the visitor to adjust the positioning of the phase plate slits using a virtual phase telescope. Specimen illumination is adjustable via the microscope illumination voltage, and the magnification can be varied from 4x to 40x. A fine focus slider is also provided to optimize specimen focus. Samples featured in this tutorial include Chinese Hamster Ovary cells, Desmids, starfish embryos, cheek cells, neuroblastoma cells, and Orlon synthetic fibers.

This interactive tutorial demonstrates how changes in the color of central and annular filters affect sample and background color when using Rheinberg illumination as a contrast-enhancing method in optical microscopy. Visitors are able to adjust the color of both the central and annular filters to preview how samples will appear under illumination with the different filter combinations

| Translational Microscopy |
|
This interactive Java tutorial simulates the scanning of a sample under the microscope at a fixed magnification. Students must first focus the sample (as is the case with a real microscope), then they are able move the sample in all directions to thoroughly explore the various features exhibited by the sample. Brightness (Intensity) and Zoom controls allow fine-tuning of the microscopic images.
