The most powerful computing network ever assembled is about to enter a new design phase. Drawing on the vast unused idle times of more than four and half million home computers, SETI@home currently gets about 15 TeraFLOPs and has cost $500K so far, compared to a typical $100+ million required for high-end supercomputing. The next generation of the SETI backbone, called BOINC for the "Berkeley Open Infrastructure for Network Computing" , is designed to make it easier for other projects to generalize this unique science architecture.

The chemistry of Saturn's moon, Titan, has long fascinated planetary scientists, particularly since it was not only discovered to have a thick atmosphere, but also one rich in organics thought to have played important roles in Earth's early biochemistry. Is Titan's chemistry biochemical? Emma Bakes of the SETI Institute seeks to answer this question, by simulating the complex chemistry of primordia.
