I recently bought a brand new Nikon D90. It's my first DSLR and I still don't know everything about the camera. Occasionally when I use it the camera won't focus properly or take pictures. Each time it happens I check and the auto-focus is on. I usually try turning the camera off for 1 minute and then turning it back on but this doesn't work. Eventually the camera starts working again. Sometimes it seems like cleaning the lens helps, but it doesn't always. When I clean it I always use a cloth designed for cleaning camera lenses. One other thing I've noticed is that the aperture isn't displayed when it this happens. Instead of showing f5 or some other number, it shows "f--". Any suggestions? Thanks for your help.

Herbal supplements which are often claimed to be safer than products made by "Big Pharma" not only contain contaminents, but are also often made by the same companies that are labeled as "Big Pharma." Not only that but Americans spend ten times as much money on supplements as they do on prescription medicines. Seems that if a company was only interested in making money they would make CAM supplements, not medicine. The first link explains that CAM doesn't work, the second explains that they are made by the same companies that make prescription medication, and the third details the various toxic contaminants that can be found in the supplements.

Not effective, not safer, and a part of "Big Pharma." I believe the conspiracy theory is disproved.
