Program arranged by Ben Patrusky and the CASW board.

As part of its half-century celebration, CASW has brought back three pioneering researchers whose talks proved especially prescient when they spoke at previous New Horizons in Science meetings. Each of them has been asked to reflect on recent developments in his field and to cast a knowing eye on what we might expect in the next 50 years.

The speakers and their fields are:

• Ralph J. Cicerone, Ph.D., President of the National Academy of Sciences and Chair of the National Research Council (climate change)
• Leroy Hood, M.D., Ph.D., President and Co-founder of the Institute for Systems Biology (genomics)
• Michael Turner, Ph.D., Director of the Kavli Institute for Cosmological Physics at the University of Chicago (cosmology)
