Why news screw up science

I'm sure you've all heard the news report about sanitizing a kitchen sponge by microwaving it for 2 minutes [CNN]. All the news organizations jumped on the story and blared headlines about how "Clean your sponge in the microwave!". One little problem. They neglected to mention the sponge must be wet. Seems a rather minor oversight until you realize microwaving a dry sponge for 2 minutes can have some disastrous results [CNN]. This is why you should NEVER trust a news organization to relay scientific findings accurately. They seem to find ways to screw it up.
