  1. Cells - Dictionary of Cell Biology (Virtual Library of Biochemistry and Cell Biology - Fenteany)
      Provides sources of information on basic cell structure and activity at an advanced high school or beginning college level. 07-12

  2. Solar Cells Improve Efficiency (CNN)
      Provides an article about greatly improved photovoltaic cells that convert energy from the sun into electricity. The cells use concentrators for greater efficiency. 10-00

  3. Solar Cells Improve Efficiency Through CIS (CNN - Environmental News Network)
      Provides an article about greatly improved photovoltaic cells that convert energy from the sun into electricity. The cells use CIS (copper indium diselenide) technology. 10-00

  4. Fuel Cells - Hydrogen Fuel Cell Manufacturer (
      Describes the hydrogen fuel cell, its benefits, and more. Also provides an animation. Hydrogen fuel cells are designed to leave no pollution when used to power alternative fuel cars or homes. Ballard is one of the world's first major manufacturers of hydrogen fuel cells for motor vehicles and other applications. 1-01

  5. Fuel Cells - Resources (
      Provides sources of information by category. 1-05

  6. Fuel Cells - Hydrogen Storage for Fuel Cells (
      Describes a breakthrough in hydrogen storage, the MAIN barrier to the use of renewable, nonpolluting hydrogen as a fuel source in automobiles. Hydrogen fuel cells can provide up to 2.5 more energy efficiency than fossil fuel power, such as gasoline or diesel. The new storage tank was developed by a team from IMPCO, Lawrence Livermore National Laboratories, Alcoa, and Thiokol Propulsion. 1-01

  7. Fuel Cells - Hydrogen Storage for Fuel Cells ( - Spice)
      Describes a new storage method for hydrogen that uses carbon nanotubes, allowing travel by automobile for thousands of miles on a single tank of hydrogen. 1-01

  8. Infrared Photovoltaic Cells (J X Crystals)
      Describes a new cell, thermophotovoltaic (TPV), that converts infrared light into electricity. It can be used in a furnace, for example, to convert wasted infrared heat into additional electricity. 6-01

  9. Regeneration of Fuel Cells (ZMitlitsky)
      Describes the Unitized Regenerative Fuel Cell (URFC). Regenerating or "recharging" hydrogen fuel in a fuel cell is a key for practical use of fuel cells in autos. 5-01

  10. Fuel Cells for Iceland (World Press Review - Asmundsson)
      Reports that Iceland plans to become the first nation use fuel cells, hydroenergy, and geothermal energy instead of fossil fuels. 2-02

  11. Cells and Biochemistry (Awesome Library)
      Provides information on cells and more.

  12. Cells (Awesome Library)
      Provides information on genes, cells, chromosomes, DNA, and more.

  13. Cells (Franklin Institute)
      Provides a lesson plan on the cell. "In your classroom, you and your students can make a model of a cell and some of its parts."

  14. Cells - Grades 1 - 6 on Molecules and Cells (San Diego State University)
      Provides 6 elementary school level lessons on molecules and cells.

  15. New Source for Hydrogen for Fuel Cells (Wired)
      "A microscopic green algae -- known to scientists as Chlamydomonas reinhardtii, and to regular folk as pond scum -- was discovered more than 60 years ago to split water into hydrogen and oxygen under controlled conditions. A recent breakthrough in controlling the algae's hydrogen yield has prompted a Berkeley, California, company to try to be first to commercialize production." 9-02

  16. Fuel Cells Based on Borate (Chrisian Science Monitor)
      "It involves simple borate - a chemical mined from the ground and used as laundry detergent."

      "The company showed a running prototype minivan at the North American International Auto Show in Detroit earlier this month that demonstrates the viability of the 'borax fuel cell.' "

      "The fuel cell runs on hydrogen taken from sodium borohydride - a man-made chemical - in its 'gas' tank. What's left is borax soap in the tank. The only emission from the tailpipe is steam." 1-04

  17. Fuel Cells Explained (
      Describes how different types of hydrogen fuel cells work. 2-04

  18. Stem Cells

  19. Sperm Stem Cells Grown Outside the Body (New York Times)
      "The ability to cultivate the sperm production cells in large numbers would make it possible to try swapping mutated genes in the cells for normal or improved versions." 11-04

  20. Method Found to Mass-Produce Embryonic Stem Cells (
      "That's important because traditional laboratory methods used to grow these cells are costly and don't produce cells fast enough to respond to increasing demands for human embryonic stem cells, said Shang-Tian Yang, a professor of chemical and biomolecular engineering at Ohio State University."

      "Federal rules forbid the federal funding of research on human embryonic stem cell lines that aren't listed on the National Institutes of Health's Human Embryonic Stem Cell Registry. There are currently 22 embryonic stem cell lines on the registry, and the demand for these cells is steadily growing."

      " 'We have to find a way to mass-produce them because traditional cell culturing methods can't meet the projected high market demand for stem cells,' Yang said."

      "He and Anli Ouyang, a doctoral student in chemical engineering, grew mouse embryonic stem cells in a bioreactor. Cell growth increased 193-fold in 15 days. At the end of that period, cell density - the number of cells that had grown in the bioreactor - was anywhere from 10- to 100-fold higher than the number of stem cells produced by conventional laboratory methods. That's several hundreds of millions more stem cells." 3-05
