December 31 -- California Academy of Science Diatom Resources
Diatoms have delicate, ornate cell walls composed of silicon dioxide. These aquatic protists' shells - glassy boxes that appear to be jewels when viewed through a microscope - are the basis for their taxonomy.  This site contains many taxonomic databases and other resources assembled by the California Academy of Sciences, whose collection includes more than 59,000 samples. An illustrated key covers more than 70 genera of diatoms.  There's also a diatom glossary, a database of genus names, and a roster of the 472 type specimens in the academy's collection. You can also read a primer on diatom biology or catch up on the latest news articles on diatoms. (I'm a diatom devotee, so I think it's a fantastic site! - Alton Biggs)

December 24 -- Scott’s Botanical Links
At Scott's Botanical Links, a sprawling collection of reviewed and rated links, you can read about famous botanists, locate photos of plants, or learn how to propagate them. Scott Russell, a botanist at the University of Oklahoma, Norman, adds a new site to the list every day or two. The content runs from highly technical DNA databases to general how-to's on plant care, and the searchable archives stretch back to 1996. http://www.ou.edu/cas/botany-micro/bot-linx/

December 17 -- The Geology of Caves:
Use this resource from The Riverdeep Current to support your discussion of
unique habitats and evolution of living things to secure a niche. Students
can also visit underground marvels and learn how they were formed. Link to
student activities with acids and bases, or create a geologic time-line,
diorama, and glossary for one of the caves your class will discover here.

December 10 -- The History of Science
This site contains a wealth of information for the beginner wanting to know
about the history of science to the expert. Links to famous biologists and
important scientific findings are one of the hallmarks of this site. For
instance, you can visit The Huxley File or listen to a radio program about a
new hominid skull found in Kenya.

December 3 -- Mother of the Jumping Gene
Barbara McClintock's genetic studies of corn revealed that genes can move around on chromosomes and won her a Nobel Prize in 1983, when she was 81. She battled skepticism toward her work and barriers to women in science. A new section of the National Library of Medicine's Profiles in Science site explores McClintock's life through photos, letters, lecture notes, and other documents. A selection of 50 publications stretches from a 1926 article on polyploidy in corn to a 1971 paper on the control of gene expression. McClintock's writing reveals her struggle to find a place in academia.

November 26 -- Scarab Central 
Scarab beetles make up about 10% of the world’s 350,000 beetle species.  Scarab beetles have been worshiped by the ancient Egyptians, treasured by modern collectors, and cursed by greenskeepers. Mary Liz Jameson, Curator of the University of Nebraska state Museum in Lincoln, says, “Although a few kinds of scarabs feast on lawns or crops, the majority are pollinators or part of our unseen garbage patrol" that mulches dead animals and dung. If you are interested in this widespread and diverse group, make a sweep through the site. The highlight is an illustrated guide to 23 New World scarab families and subfamilies that offers detailed physical descriptions and information on taxonomy, distribution, ecology, and larval forms. There's also an identification key, a glossary, and a directory of scarab researchers with brief biographies.

November 19 -- The Microbial World
This educational site is designed for students in beginning microbiology courses. It has information on the ecological importance of bacteria and fungi. The content covers more than 5 specific topics - from Dutch elm disease, to airborne bacteria, to efforts to produce a natural pesticide from the soil bug, Bacillus thuringiensis. You can also take a virtual trip to microbial hangouts like Yellowstone Park's hot springs.

November 12 -- JUST FOR FUN: HAIR SCIENCE
Brush up on hair science at the Hair Science site sponsored by L'Oréal. Find facts by combing through pages on hair growth, structure, color, and ethnic differences. Find out if hair actually turns gray as we age. Other pages explain what scientists can deduce by analyzing the composition of hair such as Napoleon was probably poisoned with arsenic, and Beethoven didn't die from syphilis. The site also plucks some revealing close-ups. Victims of split ends, take heart: even the most lustrous locks appear gnawed under the microscope.

November 5 -- Meet a Fossil Pioneer
Joseph Leidy made meticulous studies of vertebrate fossils, and showed that horses roamed North America long before the Spanish conquest He also demonstrated that the continent was once home to enormous ground sloths. This online exhibit explains the life and work of Leidy (1823-91).

October 29 -- Microbes on the Move
Looking for some video footage of bugs to spice up a virology, bacteriology, or immunology course? This video library from the University of Leicester in the U.K has more than 25 clips and animations that capture explosive bacterial growth, HIV reproduction, amoebas engulfing prey, and similar
microbial dramas. There are how-to pages on microbiology lab procedures, lecture notes, news updates, and some primers on topics such as the bovine spongiform encephalopathy epidemic and the discovery that mosquitoes spread yellow fever. Some of the footage is available on videotape.

October 22 -- MIT Biology Hybertextbook
The MIT Biology Hypertextbook is an entire introductory biology course. The 11 clearly written and illustrated chapters cover topics such as basic chemistry, genetics, photosynthesis, immunology, and recombinant DNA. To make sure you've mastered the material, try your hand at practice problems at the end of each chapter.
