How can I help in the fight against cancer?

Anyone, anywhere with access to a personal computer and the Internet, could
help find a cure for cancer by giving 'screensaver time' from their computers
to the world's largest ever computational project, which will screen 3.5
billion molecules for cancer-fighting potential.

The project is being carried out by Oxford University's Centre for
Computational Drug Discovery - a unique 'virtual centre' funded by the National
Foundation for Cancer Research (NFCR), which is based in the Department of
Chemistry and linked with international research groups via the worldwide web -
in collaboration with United Devices, a US-based distributed computing
technology company, and Intel, who are sponsoring the project.

This is the home page for the cancer research molecule screening program.
which J also referred to.

The project is run by United Devices Inc as a sort of free demonstration
platform for their commercial network computing software. The actual tasks
are set by Oxford University, UK Chemistry dept.  As well as researching
cancer drugs the system also researches smallpox cures.

The system runs through a catalogue of manufacturable drug molecules (the
ligands) and for each searches along one of the proteins known to be
involved in cancer, for a site where the ligand will dock and in some way
affect the protein.  The list of docking sites (the hits) is returned to
Oxford for further investigation.
