CK-12 Foundation is a non-profit organization with a mission to reduce the cost of textbook materials for the K-12 market both in the U.S. and worldwide. Using an open-content, web-based collaborative model termed the "FlexBook," CK-12 intends to pioneer the generation and distribution of high quality educational content that will serve both as core text as well as provide an adaptive environment for learning.

Distilled, authoritative and up-to-date information for researchers on scientific, technical and medical topics.

The little b project is an effort to provide an open source language which allows scientists to build mathematical models of complex systems. The initial focus is systems biology. The goal is to stimulate widespread sharing and reuse of models.

Both a language and a program, "little b" gives systems biologists an infrastructure for building and sharing models of cellular activity.
