Dalliance, a New Dynamic Genomic Browser
Genetic and Plastic Responses of a Northern Mammal to Climate Change
University of Alberta biologist Stan Boutin and his research team have recently published findings that North American red squirrels exhibit genetic changes in response to a warming climate. This Web site, from the Proceedings of the Royal Society, provides the abstract for this recently published research (full-text available only with paid subscription). With implications that extend far beyond the immediate research concerns of geneticists and environmental scientists, Boutin's work as presen
Institute for Systems Biology: T1DBase
T1DBase was created jointly by the Institute for Systems Biology, the Juvenile Diabetes Research Foundation International, and the Juvenile Diabetes Research Foundation/Wellcome Trust Diabetes and Inflammation Laboratory to support the work of Type 1 diabetes (T1D) researchers. T1DBase currently "includes annotated genomic sequences for suspected T1D susceptibility regions; microarray data; functional annotation of genes active in beta cells; and 'global' datasets, generally from the literature,
CSU Engine Web Pages
This resource on internal combustion engines comes from a mechanical engineering professor at Colorado State University. It is essentially an online textbook with three main chapters, which cover the topics of thermodynamics, heat transfer, and fluid mechanics involved in engine operation. Users should have an understanding of basic engine components, and a background in calculus would be helpful. Some of the material is fairly conceptual, while other parts involve analytical derivations. Many s
World AIDS Day 2004
From the Joint United Nations Programme on HIV/AIDS, this website provides information and images related to Worlds AIDS Day 2004. Notably, the site contains a downloadable version of the _AIDS Epidemic Update 2004_, which "provides the most recent estimates of the epidemic's scope and human toll, explores new trends in the epidemic's evolution, and features a special section on women and AIDS." In addition, site visitors can download a set of eleven epidemiological PowerPoint slides based on th
Multiflyer is an interactive game "for anyone who is trying to learn or 'brush up on' their multiplication." The user is in a virtual space ship and is faced with several missions on the moon, Mars, the asteroid belt, and more. To advance to each subsequent mission, the correct coordinates need to be calculated. This is where multiplication is necessary, and the user is provided with an excellent opportunity to practice the multiplication tables. The game is complete with attractive space enviro
An educational lesson plan entitled Water is offered by the Seaworld teacher resources Web site. Objectives of the unit include having students identify the three phases of water, discuss the hydrologic cycle, describe the structure of the water molecule and the properties of water, explain ocean currents, and more. The well designed lesson allows students to study various topics by reading provided text and completing the activities described such as measuring salt content in water and estimati
Top500 Supercomputer Sites
Twice a year, the Top500 Project releases a list of the 500 sites with the most powerful supercomputers. The purpose of the list is "to provide a reliable basis for tracking and detecting trends in high-performance computing." The latest version was unveiled in June, and this site examines some of the most important developments and newcomers to the list. Most important is the recently constructed Earth Simulator in Japan, which was rated almost five times more powerful than second place. Additi
GenePath: An Intelligent Assistant to the Discovery of Genetic Pathways
The Baylor College of Medicine in Houston and the University of Ljubljana in Slovenia present an improved, second version of GenePath, a "web-enabled intelligent assistant for the analysis of genetic data and for discovery of genetic networks." GenePath automates the complex process of determining gene interrelationships and users may download existing projects or start new ones from scratch. The website also provides a very detailed, nicely-designed guide to running GenePath, available as a sep
Academy for Educational Development (AED)
The Academy for Educational Development (AED) (see also Scout report for June 30, 1995) released a report in the fall of 2004, which evaluated a teacher professional development program called Teacher Leaders for Mathematics Success, or TL=MS. The study "shows significant mathematics achievement gains among students in low-income schools in the Bronx, N.Y." after participation in the program. A summary of the findings and the full report are available from this website. The report provides an ov
International Cryobiology Young Researchers Group
The International Cryobiology Young Researchers Group, an organization designed to foster communication among young cryobiology researchers and promote the science of cryobiology, has recently redesigned its Web site. Some parts of the site are restricted to members of the organization, but other parts are available to anyone. In addition to learning what cryobiology is, the most useful part of this site for educators is the section of Science Fair Ideas. Several ideas are presented for conducti
Keeping Cool at Deep-Sea Vents
This Astrobiology Magazine article reports that a research team of marine scientists has determined that water chemistry controls the location and distribution of two species of weird worms inhabiting deep-sea hydrothermal vent sites: the tubeworm (Riftia pachyptila) and Pompeii worm (Alvinella pompejana). The article includes color images of the worms and monitoring equipment, links to related web pages and other astrobiology resources, and an MP3 machine text-to-speech function.
Putting a Twist on Inquiry
After studying linear motion and learning the basic concepts involved, (inertia, force, friction), middle level students can apply their learning to nonlinear situations. Using toy tops is one way to teach students the basic concepts of nonlinear motion in a fun and engaging way. In this activity, students design, construct, and test tops, then present their designs to the rest of the class.
Earth and Space
In earth and space science, students study the origin, structure, and physical phenomena of the earth and the universe. Earth and space science studies include concepts in geology, meteorology, oceanography, and astronomy.
2.14 Summing up
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
The China Model: Appeals and limitations of state capitalism
For some people, China's impressive rebound from the recent financial recession proves that a China model has emerged and will work better for China and some other developing countries than the Western model of modernisation. Zhao argues that while... (Running Time 72:01)
Which Roof is Tops?
When you walk or drive around your neighborhood what do the roofs look like? What if you lived in an area with a different climate, how would that effect the style of roof that you might find. This is an introductory activity to explore the advantages of different roof shapes for different climates or situations.
Designing Medical Devices for the Ear
Students are introduced to engineering, and more specifically, to biomedical engineering and the engineering design process through a short lecture and interactive, hands-on activity (approximately 30 minutes long), where students design their own medical device for retrieving foreign bodies from the ear canal. In this lesson, the teacher first reviews the basics of ear anatomy then discusses how ear infections occur and how they are treated. Following antibiotic treatment, the most common treat
Students are introduced to communications engineers as people who enable long-range communication. In a demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon using a slinky. Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering.
In this lesson, students will extend their knowledge of matter and energy cycles in an organism to engineering life cycle assessment of a product. Students will learn about product life cycle assessment and the flow of energy through the cycle, comparing it to the flow of nutrients and energy in the life cycle of an organism.
