Looks good overall, very clean and well-laid-out, logical and intuitive.
Only a few minor stylistic quibbles. Nit-picky stuff, mostly:
The column formatting is a bit narrow, leaving a lot of dead space on higher-res monitors. About 40-60% of the page is dead space in my screen, in Opera, IE, and Firefox.
The graphics on some of the articles are too small to read easily, or at all; even if I increase page size to 200% (the text just ends up distorted).
Some of the light-gray text is a little too light to be easily readable on the white background. Going a shade or two darker would help.
The italiczed text in the search and contact text boxes is a little jarring.
