Wits University: Climatology Research Group
The Wits University Climate Research Group focuses its efforts on four main areas of research: atmospheric aerosols and their radiative forcing potential over southern Africa; microphysical processes in clouds; biogenic-atmospheric interactions; and air quality and management. After reading the synopsis of the many research projects, visitors can view a gallery of photographs of the group's events and endeavors. Although the research link is still under construction, individuals can find a list
Fractals, Chaos
Paul Bourke of the Astrophysics and Supercomputing department at Swinburne University of Technology is the author of this massive resource on fractals and chaos. He gives examples of many different kinds and classes of fractals, including the Mandelbrot set and various attractors; and brief explanations accompany each one. A substantial introduction to fractals covers the underlying principles and connection to chaos theory. Many stunning, high resolution fractal image galleries show elaborate p
Wired: New Browsers, Same Unwanted Ads
This article from Wired News reports on current trends in spyware and adware. The author discusses how people who stopped using Internet Explorer and started using alternate browsers, such as Mozilla Firefox, to avoid advertisements and improve internet security, may find that "spyware and adware writers are also making the switch." The author argues that as Mozilla gains more users, writers of spyware and adware programs will start writing for those browsers as well. On the positive side, the a
What's New at Sci4Kids
The Agricultural Research Service (ARS) of the US Department of Agriculture offers its latest set of brief but engaging educational activities for kids in this Web site. The recently added feature, No Horsin' Around With These Tests!, introduces immunological concepts in the kid-friendly guise of a story about horses. Two older features are also available, one on using a biocontrol method to combat dry rot fungus in potatoes and another on mites. While these subjects may not at first appear to b
UniGene
Created by the National Center for Biotechnology Information, UniGene is "an experimental system for automatically partitioning GenBank sequences into a non-redundant set of gene-oriented clusters." In addition to gene sequences, this Web site also offers thousands of novel expressed sequence tag (EST) sequences, a useful gene discovery resource. Organisms currently cataloged include human, rat, mouse, cow, zebrafish, clawed frog, fruitfly, mosquito, wheat, rice, barley, maize, and cress. Users
GLOBIO: Mapping human impacts on the biosphere
A joint project of the Norwegian Institute for Nature Research and the United Nation's Environmental Programme, Global Methodology for Mapping Human Impacts on the Environment (GLOBIO) aims to "present a simple visual overview of the cumulative impacts of increasing resource demands on man and the environment." Hundreds of environmental impact studies were synthesized with satellite imagery, infrastructure data, etc. to create this "visual overview" of past, current, and potential future conditi

Ozone depletion interactive lab
What is the process by which CFCs destroy ozone? This informational piece, part of an interactive laboratory series for grades 8-12, explores the destruction of the ozone layer by chlorofluorocarbons. Here students view a four-step animation that shows how ultraviolet light breaks chlorine free from a CFC molecule. The chlorine then destroys an ozone molecule. Additional steps show how the process can be continuous. Copyright 2005 Eisenhower National Clearinghouse
