In vivo, vitro … silico. If you're a biology student, a computer scientist crossing disciplines, or other newbie to bioinformatics who wants to make sense of jargon like “We did a BLAST search,” then check out this handy guide to molecular sequence analysis. It leads readers through “in silico” tasks such as checking a possible gene sequence or comparing a protein among model organisms.

Pretend universe. Astrophysicists can tinker with how galaxies evolve into huge clusters at this new archive of high-resolution supercomputer simulations of 100 x-ray clusters in a model universe. The site includes Java tools for seeing maps of the clusters and looking at data in virtual reality.

Physics film fest. Basic physics concepts such as wave interference, polarization, and Brownian motion come alive at this Russian site offering colorful physics animations. Covers waves, optics, mechanics, and thermodynamics.
