Multiple protocol breaches behind anthrax exposure at US federal labs
Reuters
From June 24: The safety breach at a government lab that may have exposed 84 workers to live anthrax centered on a pivotal lapse in procedure: Researchers working with the bacteria waited 24 hours to be sure they had killed the pathogens, half the time required by a new scientific protocol. The lab designed to handle extremely dangerous pathogens at the Centers for Disease Control and Prevention in Atlanta unknowingly sent live samples of anthrax to labs with fewer safeguards, where the exposure occurred.More

Medical News Today
From May 20: In what they describe as a proof of principle study, doctors in the U.S. were able to keep a woman with deadly multiple myeloma — an incurable bone marrow cancer — free of all signs of living cancer cells for over 6 months by giving her just one high dose of measles virus. Two patients received a single intravenous dose of measles virus that was engineered to kill myeloma plasma cells and not harm other cells. The team, from the Mayo Clinic in Rochester, Minnesota, says both patients responded to the treatment, showing reduced bone marrow cancer and levels of myeloma protein.More
