From the University of Illinois, Professor Stanley Maloy and Assistant Professor Rob Edwards' Web site Salmonella.org is dedicated to the study of the Salmonella bacteria genome. The site offers news and information on the bacteria's various strains, including everything from tips on preventing the infection to links to genomic sequencing data. Any Salmonella researcher or enthusiast will find this uncluttered and straightforward compilation useful.
Three Clouds Activity
The University of Michigan's educational site called Windows to the Universe (last mentioned in the January 6, 1999 Scout Report for Science and Engineering) has added many new lessons to their content. Highlights of these include two activities centered around cloud formation. The Three Clouds uses items such as a jugs and jars, a plastic bag, an aquarium thermometer, and an overhead projector to explore how clouds form and the relationship between the hydrosphere and human activity.
The Warming World: Designing for Climate Change
A workshop held in January 2003 attempted to ascertain how engineers and scientists need to change their practices to account for global warming. Road and bridge damage caused by "increased sediment loads in streams, catastrophic landslides, snow avalanches, and riverside flooding" necessitates a reevaluation of engineering design methods. Eight presentations from the workshop are given in slide form on this Web site. An executive summary is also provided, which outlines some of the proposed cha
The Missing Link: Evolution in Action
This interactive game from PBS's NOVA Online allows students to observe a population of virtual creatures as they evolve under changing conditions. Background color, controlled by the student, represents environmental conditions, while the color of the organism indicates certain adaptations and mutations. Students are able to see how changes in environmental conditions support some colors of organisms, while others become extinct. The game includes instructions and an explanation of the game's p
StarTiger is a project of the European Space Agency that is testing a new framework for research and development, with the goal of dramatically reducing the time needed to achieve a breakthrough. The basic method is to assemble a group of doctorate level researchers and engineers, put them in an environment that is free of distractions, and give them access to state-of-the-art equipment and technology. The first success of StarTiger was realized in October 2002, when, after only four months of w
MGNet "is a repository for information related to multigrid, multilevel, multiscale, aggregation, defect correction, and domain decomposition methods." In short, the material offered on the site is mainly used to solve partial differential equations. There are many resources given on MGNet, including tutorials, a preprint archive, and information on upcoming conferences. Quite a few software packages can be downloaded from the site; however, they require a specific decompression utility. MGNet a
Ars Technica: CPU and Chipset Guide
An informative collection of articles on computer hardware and operation is presented by Ars Technica. Many of the more recent articles (July 2002 to February 2003) have shifted from focusing on specific technologies and platforms to explaining basic principles of computer architecture. This includes "pipelining and superscalar execution," bandwidth and latency, multithreading, and CPU caching. Other articles delve inside new microprocessors and describe new features and notable architectural im

National Estuaries Day
Get the most out of National Estuaries Day (October 5, 2002) by visiting this Web site from the National Oceanic and Atmospheric Administration (NOAA). Follow a link to Estuary Live!, which offers online interactive fieldtrips through a number of estuaries around the nation. Guided tours of eight estuaries will be webcast live October 3 and 4, supplemented by videos from a number of other estuaries. Internet participants "will have an opportunity to see the fascinating creatures that make estuar
As part of the University of California Santa Barbara Library, the Astronomy subject Web page contains dozens of links on the subject. Sites are categorized in indexes and gateways, NASA pages, observatories, organizations and associations, current topics, interactive resources, and periodicals. If all that isn't enough, the site even has an astronomy picture of the day.
Flesh and Bone: A New Generation of Scientists Bring Dinosaurs Back to Life
The online version of the March 2003 issue of National Geographic Magazine (NGM) includes this interesting multimedia feature about "a new generation of scientists [that] is using computer modeling and a better understanding of living animals to bring dinosaurs back to life -- virtually." In addition to the feature article, the Web site includes an online-exclusive image gallery, "On Assignment" notes from National Geographic writers and photographers, related Web links and other resources, and
PicSNP: A Catalog of Non-Synonymous SNP
Maintained by Hangil Chang at the University of Tokyo, PicSNP "is a catalog of non-synonymous Single Nucleotide Polymorphism (SNP) in the human genome." Recently updated, the database allows users to select SNPs by gene name, function of affected genes, biological process relevant to affected genes, or cellular component that contain affected genes. The site does not include much instruction on how to use the database, meaning it is most suitable for users who are familiar with the subject.
Missouri Botanical Garden Research: Ethnobiology Discussion Forum
As part of a process funded by the National Science Foundation (NSF), the Missouri Botanical Garden's online ethnobiology discussion forum invites ethnobiologists to "intellectually define [the] field, its intellectual content, methods, and applicable analyses and to review the present state of and need for education, funding and international collaboration in ethnobiology." This ongoing discussion will result in a white paper addressing how ethnobiologists can meet NSF's call for rigorous scien
Study Points to Acid Rain in Decline of Songbirds
New research from the Cornell Lab of Ornithology points to acid rain as a major cause of songbird decline, where previous research focused on forest fragmentation. This Web site is a brief article highlighting the research findings from the Atlanta Journal-Constitution, published on the Natural Resources Defense Council's Web page.
Brainpop describes itself as the leading producer of educational animated movies.

Science Sampler : Six rules for integrating the arts
How can teachers help their students to imagine and construct knowledge in the way that science sees it and simultaneously weave the arts into science lessons? By using the following six simple rules for integrating the arts into science learning, students' imagined worlds come closer to the way science sees them using an inquiry-based format.
Learning math : Measurement
This college level course, developed for elementary and middle school teachers, begins with the fundamentals of measurement, then examines standard units in the metric and customary systems. Online workshop sessions cover measurement of a circle, area and volume formulas, angle measurement, and indirect measurement encountered in trigonometry. The final session explores ways to apply these concepts to K-8 classroom teaching. Each of its ten sessions contains video programming, problem-solving ac
Teaching Box: The Feeding Frenzy, Seasonal Upwelling
This teaching box is designed to teach students about the biotic and abiotic factors that drive the process of upwelling in the oceans. Students will deepen their understanding of the dynamics that create a seasonal abundance of marine life in coastal upwelling zones by exploring marine food webs, primary food production in the ocean, density and wind-driven currents, and seasonal changes in resources. By working backwards, students will discover that wind-driven upwelling supplies phytoplankton
Science Sampler: Multiple Intelligences and Lab Groups
Science teachers who are committed to excellence in the classroom continually seek ways to improve teaching and learning, and the concept of multiple intelligences holds promise as a method for accomplishing this. Acknowledging these intelligences offers teachers an interesting opportunity to appeal to the different personalities and learning styles that are present in the classroom. In this research project, the theory of multiple intelligences was integrated into a seventh grade science curric
