Virus off the hook for cancer, fatigue
A virus that has been implicated in causing prostate cancer and chronic fatigue syndrome may be a laboratory contamination problem and not a human pathogen after all.

But a new study suggests that previous experiments that found the virus inserted into human genes were faulty due to contamination from a laboratory technique that replicates DNA. The observation, reported Feb...
