What do you do with your used, broken, or obsolete electronic devices? Where can you take your electronics, and what should you look for to protect both your identity and the environment? You can find the answers at the Electronics Industry Alliance's recycling Web site, which provides an online guide to electronics recyclers and disposal options across the United States.Go to: http://www.ecyclingcentral.com/

While you're sending an e-mail or surfing the Web, your computer could be helping to tackle one of Africa's major challenges: malaria. In a project coordinated by CERN, volunteer computers in homes and offices run a simulation program called MalariaControl.net, developed by researchers at the Swiss Tropical Institute. The program simulates how malaria spreads through Africa. Running the simulations on thousands of volunteer computers will enable researchers to better understand and improve the impact of introducing new treatments.Go to: http://www.africaathome.org/

The Applied Math and Science Education Repository (AMSER) serves up applied math and science resources in an easy-to-use format. Though specifically created for teachers and students in community and technical colleges, AMSER is available to everyone. Users can find links to a wide assortment of materials, from large Web sites focusing on an individual applied science or math topic to Flash animations that demonstrate specific science or math principles in action.Go to: http://amser.org/

With a colorful, animated slide show, this Web site introduces visitors to the way vast streams of physics data will flow, starting later this year, from the world's most powerful particle accelerator to 7,000 physicists around the world. Potentially packed with revelations about matter, energy, and the universe, some 15 million-billion bytes of information per year should radiate annually from the accelerator known as the Large Hadron Collider to three tiers of computing facilities distributed worldwide.Go to: http://gridcafe.web.cern.ch/gridcafe/animations/LHCdata/LHCdata.html

The U.S. Geological Survey has launched a new Web site about the threat of natural disasters. It provides seven easy-to-understand fact sheets on earthquakes, floods, hurricanes, landslides, tsunamis, volcanoes, and wildfires. The site also highlights resources and information available from the USGS and provides links to individual hazards Web pages for more detailed information.Go to: http://www.usgs.gov/hazards/

Created by the GrassRoots Action Center for the Environment (GRACE), this Web site aims to help consumers understand problems with the nation's food supply and offer viable solutions and alternatives. It provides an introduction to the burgeoning sustainable food movement and information about organizations, people, and programs that are trying to change the way people think about food.Go to: http://www.sustainabletable.org/

This Web-based project represents the work of three Calgary artists: Vera Gartley, Arlene Stamp, and Mary Shannon Will. These artists use computers and other technology to generate designs that simulate growth patterns found in nature, explore image and text relationships by engaging viewers in movement and drawing, and combine layers of color and pattern with a musical score.Go to: http://www.artificial-life.net/
