Scientists tinkering with bird flu in labs have stumbled onto some potentially dangerous findings.
As of now, the deadly bird flu virus can't be transmitted through the air.
But scientists have figured out how to genetically alter the virus to make it airborne.
Two separate studies were set to be released, but had to be delayed, because of fears that terrorists might use the research to make biological weapons.
However, the National Science Advisory Board for Biosecurity also said the data could help prevent a future outbreak.
The journals "Science" and "Nature" have now published the studies, stripped of details, about the airborne version of the mutant bird flu strain.
