May 6, 2014 — Adelie penguins, which breed in huge colonies on the rocky Antarctic Peninsula, harbor a version of the avian influenza virus. But this strain doesn't make humans or the birds sick.
Apr 5, 2013 — Sixteen cases of a new flu in China have touched off a major effort to determine what kind of threat it might be. Flu experts want to know where the H7N9 virus is coming from and how it gets around.
Feb 15, 2012 — Scientists working with bird flu recently called a 60-day halt on some controversial experiments. The unusual move has been compared to a famous moratorium on genetic engineering in the 1970s. Key scientists involved in that pause on genetic research disagree on whether today's furor over bird flu is history repeating itself.
Feb 9, 2012 — The scientists, journal editors and others who attend are expected to review the facts and the most pressing issues related to this specific work, rather than have a broader discussion about the possibility of international oversight of potentially worrisome biological research.
Jan 20, 2012 — Scientists working with a highly contagious, lab-created strain of bird flu will suspend their research for 60 days. The pause will make possible an international debate on the merits of the work, they say.
Nov 17, 2011 — At a recent conference, a Dutch scientist said he'd made bird flu virus highly contagious between ferrets — the animal model used to study human flu infection. Just five mutations did the trick. Security experts fear publishing the work could spur development of new weapons.
Aug 29, 2011 — The United Nations' Food and Agriculture Organization warned of a "possible major resurgence" of H5N1 influenza, including a mutant virus that appears to be unfazed by available vaccines.
