One of the most appealing features of this Web site is t
Design of a Primitive Nanofactory
This 86-page paper, published in October 2003, was written by the Director of Research at the Center for Responsible Nanotechnology. He proposes "an architecture for combining large numbers of programmable mechanochemical fabricators into a manufacturing system, or nanofactory, capable of producing a wide range of human-scale products." Rather than calling for the development of entirely new technologies, the author attempts to describe a system that can be built with current engineering practic

Visitors can view the many fantastic images collected at the Apache Point Observatory, the site of the SDSS tel
Earth Science Week
The American Geological Institute organizes Earth Science Week (ESW) each year in October "to help the public gain a better understanding and appreciation for the Earth Sciences and to encourage stewardship of the Earth." The website offers highlights, evaluations, and news clippings of past ESW events. During the months leading up to ESW, users can search for Earth Science events taking place in their area. Teachers can find numerous classroom activities for grades K-12 based in the National Sc
Partnerships to Advance Learning in Science: Java Simulations
Provided by Iowa State University, the Partnerships to Advance Learning in Science: Java Simulations Web site contains several interactive science simulations. Visitors can explore advection, the energy budget, adiabatic processes, and radiation. For example, the mountain simulation teaches about adiabatic processes by allowing users to adjust various parameters such as temperature, dew point, mountain slope, and cloud base altitude. The simulation then blows a leaf over the mountain and moves i
Consensus CoDing Sequence Database
The Consensus CoDing Sequence (CCDS) Database "project is a collaborative effort to identify a core set of human protein-coding regions that are consistently annotated and of high quality. The long-term goal is to support convergence toward a standard set of gene annotations on the human genome." CCDS project collaborators include the National Center for Biotechnology (NCBI), European Bioinformatics Institute (EBI), Wellcome Trust Sanger Institute (WTSI), and University of California, Santa Cruz
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
Bush Cites Need to Develop Affordable Hydrogen-Powered Fuel Cells
In his State of the Union Address on January 28, 2003, President Bush made a case for further fuel cell development. Current efforts in this area have not determined how to efficiently produce or extract hydrogen for the cells. In hopes of solving this problem, Bush proposed a $1.2 billion FreedomFUEL initiative. The first site discusses the initiative and its potential to create a nearly pollution-free method of electricity generation.
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.
Professor Talman of the Metropolitan State College of Denver offers this site as a reference for both students and teachers of mathematics. It is an assortment of animations that demonstrate many mathematical concepts, which are often difficult to visualize. The only downside of the animations is the lack of explanation associated with them. Some have short descriptions, others are somewhat self explanatory, but the rest can initially be quite confusing.
