Jeremy Siegel: Interest Rates Look Stable, but Beware the China Bubble
The U.S. economy may be getting stronger, but that doesn't mean interest rates will go up when the Federal Reserve meets next week on January 31. According to Wharton finance professor Jeremy Siegel, interest rates should hold firm at their current level for quite a while, and "the big question for the market is whether there will be any drops at all this year." He believes there is "a balance in the economy between strength and moderate inflation," and the Fed is unlikely to move interest rates
Cells - Centers for the Week of 8/30/10
Mrs. Matthews students rotate through science centers each week. This week, the class is learning about living things, the parts of a plant and animal cell, and unicellular organisms. Their centers for the week include (1) a video about microbes found on Watchknow called Magic School Bus is in a Pickle (2) three interactive microscope websites on the Whiteboard (3) an experiment with a chicken egg (one large cell) soaked in vinegar to reveal the membrane (4) an art activity where the stud
Semiconductor device technology has transformed our world by making possible supercomputers, personal computers, cell phones, ipods, and much more that we now take for granted. Moore's Law observes that the number of transistors (the basic building blocks of electronic systems) per electronic chip doubles each technology generation. This doubling of transistor density each technology generation has continued since Gordon Moore, one of the co-founders of Intel, made his observation in 1965. It ha
Engineering Nanomedical Systems
This course will cover the basic concepts of design of integrated nanomedical systems for diagnostics and therapeutics. Topics to be covered include: why nanomedical approaches are needed, cell targeting strategies, choice of core nanomaterials, technologies for testing composition and structure of multilayered nanomedical systems, optimizing zeta potentials, design and testing of cell and intracellular targeting systems, in-vivo issues, drug delivery and proper dosing, assessing efficacy of dru
What are all those crazy parts and pieces of a cell? What is the procaryote and the eukaryote? Video explains these two different types of cells.
The Discovery of Penicillin
In this video segment adapted from A Science Odyssey, learn what led British researcher Alexander Fleming to the chance discovery of antibacterial properties of a mold extract he later named penicillin. After treating World War I battlefield casualties, Fleming began searching for compounds that would ward off infections in humans. Returning from vacation in the summer of 1928, he noticed that mold was partly covering one of the agar plates in which he had been growing bacteria, and that the mol
Eric Giler wants to untangle our wired lives with cable-free electric power. Here, he covers what this sci-fi tech offers, and demos MIT's breakthrough version, WiTricity -- a near-to-market invention that may soon recharge your cell phone, car, pacemaker. As the CEO of MIT-inspired WiTricity, Eric Giler has a plan to beam electric power through the air to wirelessly power your laptop or recharge your car. You may never plug in again. Run time 10:13.
Mitosis In Action
Observation of the cell division of C. elegans cells from a 1 cell embryonic stage over a 50 minute time course at 20 second intervals. Black and white with music. Grades 5-12. 54 sec.
Cell Division In Lung Cells
Uses contrast microscopy to visual the process of cell division. Images in black and white with labeling and narration of what is occurring at each step. Grades 7-12. 58 sec.
The Stages of Mitosis
This is a computer-animated clip from Stages of Mitosis, a promotional piece, which begins with a fly-through of cells preparing to undergo mitosis (cell division).
Upon entering a cell we are introduced to various organelles of the inner cell and the key events involved in mitosis.
The Cell Cycle
The cell cycle is a series of events that cells go through to
reproduce and create more cells. Learn about the stages of the cell
cycle with information from a science teacher in this video.
Interphase in the Cell Cycle
Interphase is a part of the cell cycle in which the cell
reproduces more DNA. Learn from a science teacher how interphase prepares a cell to split in half in this video.
This is a video using computer animation that discusses what cell-mediated immunity is. Good sound quality. (03:04)
Biology Cell Cycle
This brief video, while showing the various parts of a cell, shows how cells replicate and divide.
Tour of the Cell
This tour of the Cell and the organelles withing the cell includes narration of each organelle as well as its job decription. Run time 03:09.
Somatic Cell Transfer
Shows how a skin cell nucleus is used to make an embryonic stem cell. 3-D color animation with narration. 54 sec.

The Fungi Classification
A fungus is a member of the kingdom Fungi . The fungi are heterotrophic organisms possessing a chitinous cell wall. The majority of species grow as multicellular filaments called hyphae forming a mycelium; some fungal species also grow as single cells. This interactive web page gives you pictures of specific examples of the fungi classification, along with writen details for most. No run time.
The Busy Electron Oxidation and corrosion reactions are explained, and real world solutions to these problems are discussed. The principles of electrochemical cell design are explained through batteries, sensors, and a solar-powered car. New applications of lithium batteries are spurring medical and technological advances.

Solar Technology GE researcher Vlatko Vlatkovic discusses solar technology development at GE from the roof of GE's global research center in New York. It is a solar panel test set up. He shows a silicone solar cell and explains how the sun hits the cell and is converted to energy. He explains that the system is still very expensive and not very attractive and how they are trying to produce a more efficient, less expensive, and a better looking u
