Brain food. Whether it's phantom limbs, Gestalt psychology, creativity, or Creole language, you can learn all about it at The MIT Encyclopedia of Cognitive Sciences. This new resource contains 471 backgrounders on topics in philosophy, linguistics, neuroscience, psychology, and other areas.

Lesson in bonding. Students can get a feel for protein folding theory with these interactive demos on alanine, an amino acid. Rotate bonds to change alanine's energy state or help it form a helix, or learn more by following biomolecular modeling links.

Mutated mice. One way to study what genes do is to disrupt them with a tagged mutation. This group has posted hundreds of these “gene trap insertions” in mouse stem cells, mostly for secreted and membrane proteins, and plans to offer mice and stem cells to researchers.∼skarnes/resource.html
