Plant Cell Motility and Laser Microsurgery of Cytoplasmic Strands
 Plant cells are shaped by rigid cell walls. Osmotic forces press the plasma membrane tightly against these walls. The walls can be removed with enzymes. The remaining structures, the protoplasts, are now bordered by the plasma membrane. Since the shaping force of the wall is missing, isolated plant protoplasts are usually perfectly spherical in shape as a result of non-directional osmotic forces. Run time 04:19

Elodea Cytoplasmic Streaming
About 10-15 minutes after preparing a wet mount of an elodea leaf, evaporation of some of the water makes it possible to see chloroplasts in motion inside of the cytoplasm. "Cytoplasmic streaming" is defined as the movement of the fluid substance (cytoplasm) within a plant or animal cell. This is the mechanism for the transport of nutrients. Run time 02:31.

3D Animation of a Heart Attack
This 3d medical animation illustrates the story of a heart attack from a blocked coronary artery due to th inflammation of blood vessels. Beginning with damage to the endothelial arterial wall, the animation shows how a white blood cell entering the wall of the artery changes into a macrophage, grabbing and digesting cholesterol. As the cell does its job, it transforms into a foam cell, which, unfortunately, becomes part of the plaque within the blood vessel wall. Ultimately, over a period of

Inside a Solar Cell
In this interactive activity adapted from NOVA Online, learn how a typical photovoltaic cell converts solar energy into electricity. Explore the components of a photovoltaic cell, including the silicon layers, metal backing, antireflective coating, and metal conductor strips. Using animations, investigate why the silicon layers are doped with phosphorous and boron, and how an electric field is used to generate electricity from sunlight. No audio.

Brian Kernighan: The Changing Face of Programming
The rapid evolution of languages, tools, environments, and expectations presents major challenges and opportunities for programmers and for software engineering education. This is true across all kinds of programming, but is especially so for Web systems, which are now routinely written in untyped scripting languages and include Ajax, mashups, toolkits, frameworks like Rails and Django, and a profusion of interfaces, all operating asynchronously on distributed systems. For the past 7 or 8 years
