While Democratic Presidential hopeful Barack Obama unveiled an impressive stable of science policy advisers last week, his opponent John McCain has yet to ante up.

As Wired reported on Wednesday, the Obama science team includes Nobel laureates Harold Varmus and Peter Agre along with three other noted scientists - Stanford agricultural researcher (and former Monsanto board member) Sharon Long, University of Chicago astrophysicist Donald Lamb, and former American Association for the Advancement of Science president and University of Michigan geneticist Gilbert Omenn.

At a forum on Thursday in Washington, DC, which featured Obama's health policy adviser, Dora Hughes and her McCain campaign counterpart, Jay Khosla, it sounded as though the Republican candidate was ready to introduce his science advisory team to the world. During the forum, which was webcast and hosted by science advocacy group Scientists and Engineers for America, Khosla was asked who McCain's science advisers were. Though Khosla wouldn't give names, he did say: "We have a science group that works for the Senator McCain campaign. Our communications shop can provide you with the names of the science advisers."

After repeated calls and E-mails to the McCain campaign, however, no science advisers were offered up. At one point a volunteer answering phones for the campaign said, "They don't have any listed."
