The field of stem cell research is exciting, fast moving, and ever expanding. As such, websites such as Stem Cell Assays—which is designed to bring together professionals in the field—are incredibly valuable resources. Stem Cell Assays is a great site for the latest stem cell news, as well as for articles and blog posts about techniques, protocols, and other related resources. The posts are organized on the page in a newsfeed-like format, with the most recent entries at the top of the page. Similarly, users can browse the archive by chronology; however, users can also browse the content by category. Categories include topics such as cancer, cell culture, education, gadgets, reviews, and web tools. The site is updated quite frequently, and—as is obvious by the categories given above—contains a diverse range of material.
