Now here’s a site with a lot of potential. Whether you are a seasoned stem cell researcher, or someone who always thought stem cells had something to do with plants, this site by the National Academy of Science has a wealth of information for you. The booklet “Understanding Stem Cells” covers everything from what a stem cell is to discussing the major ethical issues regarding stem cell research. This colorful, reader-friendly booklet can be downloaded, or you can even request (free) hard copies. If dense legal jargon is more your cup of tea, you can download the 65-page “Guidelines for Human Embryonic Stem Cell Research.” Coupled with the event calendar of upcoming symposia, this site offers all of the tools needed to differentiate a stem cell neophyte into an ES expert.
