"iBiology’s mission is to convey, in the form of open-access free videos, the excitement of modern biology and the process by which scientific discoveries are made."

Database of useful biological numbers (through harvard.edu)

"The Medical Biochemistry Page has been a continuously updated and expanding, free educational resource on the internet since 1996. The goal of the site is to provide extensive, detailed, and accurate information on a range of topics centered on the foundation of Medical Biochemistry. In addition to content that would be found in most Medical Biochemistry textbooks, The Medical Biochemistry Page contains integrated content related to physiology and pharmacology."

"Science.gov searches over 60 databases and over 2,200 scientific websites to provide users with access to more than 200 million pages of authoritative federal science information including research and development results."

A free, online archive and distribution service for unpublished preprints in the life sciences. Most articles have not undergone peer review.

"GenBank ® is the NIH genetic sequence database, an annotated collection of all publicly available DNA sequences. GenBank is part of the International Nucleotide Sequence Database Collaboration, which comprises the DNA DataBank of Japan (DDBJ), the European Nucleotide Archive (ENA), and GenBank at NCBI. These three organizations exchange data on a daily basis."

"The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history"
