Remember last week when the U.S. National Institutes of Health asked American scientists, "Pls check yer vials!"? (We're paraphrasing.) Apparently, the agency has taken its own advice to heart. In a search of its own facilities, they found forgotten bottles containing ricin--a potent poison--as well as vials of organisms that cause botulism, plague and other illnesses, the Associated Press reports. The ricin sample is estimated to be 85 to 100 years old.
