Nobel Laureates Paul Boyer, Steven Chu and Louis Ignarro (far right) share a laugh with Mike during the Nobel Laureates Science and Medicine panel at the Milken Institute 2002 Global Conference. While the scientists, along with Nobel Laureate Walter Kohn (not shown), voiced differing opinions on a range of issues -- obesity and heart disease; aging and population growth trends; alternative sources of energy and global warming; and cloning and genetically altered foods -- they all agreed that scientists need to better explain to the public the benefits of research. The Science Nobel panel, along with the panel of Economic Nobels, is the Global Conference's signature event. For a summary of the Science Nobel panel, click here.
