View Resource Hot-Water Worms May Use Bacteria as Shield

This National Geographic news article highlights research being done to study the Pompeii worm (Alvinella pompejana), the most heat tolerant complex organism on Earth, and its microscopic symbionts. Bacteria on the worms' backs act like firefighters' blankets, shielding the worms from intermittent blasts of hot, metal-rich water. Scientists are currently characterizing the chemistry of the vent...

View Resource Singing Insects of North America

How does one distinguish a katydid from a cricket? This website provides an answer to that question, along with samples of calls from other insects, including cicadas. The site was created by Thomas J. Walker and Thomas E. Moore, and it was designed to be of assistance to both professional and amateur biologists interested in studying singing insects. First-time visitors should scroll down to the...

View Resource Virtual Microscope

The Virtual Microscope is a NASA-funded project that provides simulated scientific instrumentation for students and researchers worldwide as part of NASA's Virtual Laboratory initiative. This site serves as home base for the Imaging Technology Group's contributions to that project- namely virtual microscopes and the multi-dimensional, high-resolution image datasets they view. Currently we provide...

View Resource Animals in Motion

In this lesson, learners use a Flash animation running in a browser to study how animals and humans move. Students examine images captured by Eadweard Muybridge in the late nineteenth century; by starting, slowing, and stopping the animation, learners gain valuable insights into biomechanics of bipeds and quadrupeds.

View Resource Laboratory Transmission of Xanthomonas Campestris Pv. Raphani by a Tardigrade (Parachela = Macrobiotidae)

This Florida Entomologist scholarly article, written by Thomas G. Benoit, Jennifer Locke, James R. Marks and Clark W. Beasley, (3-page PDF) investigates the ability of tardigrades, also known as water bears, to transmit phytopathogenic bacteria to suitable plant hosts where they could then cause disease. The study showed that when tardigrades were inoculated with Xanthomonas campestris pv....
