GENEVA/LONDON (Reuters) - Two studies showing how scientists mutated the H5N1 bird flu virus into a form that could cause a deadly human pandemic will be published only after experts fully assess the risks, the World Health Organisation (WHO) said on Friday.

NEW YORK/CHICAGO (Reuters) - To reach his office in Galveston National Laboratory, where scientists study deadly pathogens such as the Ebola and Marburg viruses, director James Le Duc swipes his key card at the building's single entrance, which is guarded 24/7 by Texas state police.

LONDON (Reuters) - A scientist researching a potentially highly lethal airborne version of the H5N1 bird flu virus said on Wednesday he must be allowed to pursue his studies if deadly pandemics are to be prevented.

NEW YORK (Reuters) - An international debate over whether to censor new research on bird flu may soon prove academic, as other laboratories close in on similar findings showing how one of the most deadly viruses could mutate to be transmitted from one person to another.

NEW YORK (Reuters) - Researchers studying a potentially more lethal, airborne version of the bird flu virus have suspended their studies because of concerns the mutant virus they have created could be used as a devastating form of bioterrorism or accidentally escape the lab.

CHICAGO (Reuters) - A U.S. scientific advisory board Tuesday asked two scientific journals to leave out data from research studies on a lab-made version of bird flu that could spread more easily to humans, fearing it could be used as a potential weapon.
