Nearly two dozen scientists have proposed a series of experiments that will create an even more virulent strain of H7N9, the recently identified avian influenza virus that has killed 43 of its 130-plus known victims, in what they say is an effort to better understand how the virus could develop into a deadly pandemic strain in nature. The scientists include Ron Fouchier at Erasmus Medical Center and Yoshihiro Kawaoka at the University of Wisconsin-Madison, who sparked controversy last year with experiments involving another deadly influenza strain.
