This story why you should never take your medical news from newspapers. Somewhere toward the end, it's results in cell cultures. Animal studies pending, and human studies way out. Lot of things work differently in live tissue compared to cells in a petri dish.
This sounds big. Can anybody knowledgeable on the subject provide additional information?
Whenever I see "could" in an article these days, I just roll my eyes. We might have actual clinical results of stories like these in months—a blind test in more months after that.
