The FY 2011 budget: So much for transparency
Cabinet officials and other administration leaders met with reporters yesterday to outline the President’s Fiscal Year 2011 federal budget. That spending blueprint includes $147-billion-and-change for research and development programs. But in contrast to past years, details tended to be skimpy today — and any chance for followup or verification of apparent trends has proven more difficult than usual.

The skinny on indoor ozone
Indoor concentrations of ozone tend to be far lower than those outside, largely because much gets destroyed as molecules of the respiratory irritant collide with surfaces and undergo transformative chemical reactions. New research identifies a hitherto ignored surface that apparently plays a major role in quashing indoor ozone: It’s human skin. And while removing ozone from indoor air should be good, what takes its place may not be, data indicate.
