Tumor Suppressors - Cell Biology
This is an introductory survey of cell and developmental biology. The assembly of supramolecular structures; membrane structure and function; the cell surface; cytoplasmic membranes; the cytoskeleton and cell motility; the eukaryotic genome, chromatin, and gene expression; the cell cycle; organelle ...
Visualizing the Cytoskeleton - Cell Biology
This is an introductory survey of cell and developmental biology. The assembly of supramolecular structures; membrane structure and function; the cell surface; cytoplasmic membranes; the cytoskeleton and cell motility; the eukaryotic genome, chromatin, and gene expression; the cell cycle; organelle biogenesis, differentiation, and morphogenesis.
General Biology Fall 2008
This course is a general introduction to cell structure and function, molecular and organism genetics, animal development, form and function.
Zebrafish embryo development
Early development of Danio eggs note the internal structure and the cluster of eggs (note the large yolk attached to the two-cell egg). The cells all divide at the same time. Within two days this mass of dividing cells will take on the shape of a zebrafish larvae.

National Middle School Science and Technology Bowl
Two competitions: an academic competition in which middle school students answer fast-paced questions about math and science (earth, physical, life, and general science) and a model fuel cell car competition that challenges students to design, build, and race model cars.
Although a great deal of emphasis of the course is on the structures of the organs and tissues, this is not a course based solely on pure microscopic descriptions. Lectures and laboratory sessions will focus on the integration of structures with functions, drawing from many disciplines (light/electron microscopy, cell biology, biochemistry, physiology etc.). Highlights of the course are its magnificently detailed collections of tissues as represented in the Circulatory Lecture.
Often referred to as the powerhouses of the cell, mitochondria provide the energy that powers nearly every cellular process. This essay by John Ross describes in detail the structures and functions of these amazing organelles.
In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They ...

Test your knowledge about cell differentiation, cell function and tissue culture.
"Communication System Design, Spring 2006"
" This course presents a top-down approach to communications system design. The course will cover communication theory, algorithms and implementation architectures for essential blocks in modern physical-layer communication systems (coders and decoders, filters, multi-tone modulation, synchronization sub-systems). The course is hands-on, with a project component serving as a vehicle for study of different communication techniques, architectures and implementations. This year, the project is focu
How to Create An In-Cell Bar Graph Using Open Office Calc.
This quick tutorial shows how to compare data using an in-cell bar graph in the Open Office Calc Program.
Junior Solar Sprint and Hydrogen Fuel Cell Car Competitions
The National Renewable Energy Laboratory hosts the U.S. Department of Energy's Junior Solar Sprint/Hydrogen Fuel Cell (JSS/HFC) Car Competitions. Middle School teams from all over the Colorado Region participate in this fun, educational and exciting event. Teams work together building solar and/or hydrogen fuel cell cars with guidance from a parent or teacher coach to compete in race and design categories. A "Spirit Award" is also presented to the team recognized for good sportsmanship. Building
Cell Division in Animals
This is a brief computer-animated video that describes differentiation in animals at the cellular level (cell division). Once the cells are differentiated they lose the ability to divide. As a result, one cannot grow a whole animal in a culture medium from a single cell. The growth of the whole animal in a single cell is only possible in the early stages of development - after the first one or two divisions. Other key words include: ectoderm, mesoderm, and endoderm. Run time 01:51.
Concentrate on Distracted Driving: A Challenge to MIT Students from U.S. Transportation Secretary Ra
From the MIT News Office:
Research has shown that talking on a phone while driving, even with a hands-free cell phone, causes as much of an impairment to driving ability as being drunk. And yet, says U.S. Secretary of Transportation
Ray LaHood, while the nation has successfully cracked down on drunk driving, when it com
