What was supposed to be a 60-day moratorium on certain experiments involving lab-altered bird flu has now lasted more than eight months. And there's no clear end in sight.
Researchers still disagree on how to best manage the risks posed by mutant forms of highly pathogenic H5N1 bird flu. The altered viruses are contagious between ferrets, which are the lab stand-in for humans. The fear is that these germs could potentially cause a deadly flu pandemic in people if they ever escaped the lab.
Madhulika Sikka, who has been Morning Edition's executive producer since joining NPR six years ago, will become the organization's executive editor in January.
In announcing the promotion this morning, NPR Senior Vice President for News Margaret Low Smith lauded Sikka's work at Morning Edition, saying she "brought real vision" to the show and that it has "evolved into a more interesting and relevant program" under her leadership.
For all their variety and variation, cities are, at their root, physical systems. That means, at some fundamental level, they are also expressions of the laws of physics. In physics size matters (or "scale" as we call it). Physicists learn different things about an object by looking at it from different scales. In our first exploration of physics and cities we stayed at the street level. At that scale we saw cities as machines: cars and elevators, pipes and plumbing. Then we went up to the roof. At that scale we saw cities as engines, vast systems for turning energy into work.
Saying that the global economic recovery "has suffered new setbacks, and uncertainty weighs heavily on the outlook," the International Monetary Fund today warned that the probability of "recession in advanced economies and a serious slowdown in emerging market and developing economies" next year have gone up.
The fund said its research indicates the risk of those things occurring in 2013 "has risen to about 17 percent, up from about 4 percent in April 2012."
