(AP) — Four months ago the U.S. government sought to block publication of two studies about how scientists created an easily spread form of bird flu. Now a revised version of one paper is seeing the light of day with the government's blessing.
The revision appears online Wednesday in the journal Nature.
It's the near-conclusion to a drama that pit efforts to learn how to thwart a global flu epidemic against concerns about helping terrorists create bioweapons. The second paper, which is more controversial because it involves what appears to be a more dangerous virus, is expected to be published later in the journal Science.
