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

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.
