Cell Fractionation in Tetrahymena
To illustrate cell fractionation, nuclei are isolated from the ciliated protozoan, Tetrahymena thermophila. A table top clinical centrifuge is used for the fractionation steps and the procedure is monitored microscopically using a differential stain. To determine the efficiency of the procedure, cell and nuclear counts are determined with a hemacytometer. To quantify DNA, the Diphenylamine Reaction is carried out and the amount of DNA per nucleus is calculated.

Bacterial Quorum Sensing and Bioluminescence
The bacterium Vibrio fischeri produces light when it is growing symbiotically in the light organ of certain fish and squid species. The bacteria sense they are in a light organ because they are present at a high bacterial cell density, which they detect through "quorum sensing." We use several bacterial strains, each of which carry only part of the genes responsible for the quorum sensing and bioluminescence process. We use chemical and genetic complementation to determine which genes are lackin

Essential Science for Teachers: Physical Science: Session 2. The Particle Nature of Matter: Solids,
In-depth interviews with children that uncover their ideas about the topic at hand.,The segment provides examples of questions used to probe the student's ideas about particles, particularly, that substances such as air are made up of invisible tiny particles called atoms that are far too small to be seen through a regular microscope. When asked if he could draw air, the student responds that air cannot be drawn because it is just a bunch of invisible particles called atoms, but when probed furt

The News: HeartMate II
In this commercial, we open on a doctor reading a thank-you letter from a patient. Dr. Jennifer Peura tells us how in medical school, she dreamed of finding all the answers for her patients. She explains how heart patients for years were tethered to a giant device, until MUSC acquired a device the size of a cell phone to replace their failing hearts. She is summoned to a patient room, where we see that her heart patient is now a proud uncle, celebrating the birth of his niece.

Virtual laboratories in Molecular and Cell Biology - Immuno-electron-microscopy
A virtual laboratory that includes immuno-gold labelling and transmission electron micrography (immuno-EM). It allows the student to study intracellular-traffic pathways of two cell-surface receptor molecules, following stimulation of the cells with their specific ligand, for different time periods. The programme first introduces the theory underlying the techniques and includes a video of EM work in a real laboratory. The student is then taken through a series of questions which requires them t

Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.
