HumansGerms’ persistence: Nothing to sneeze at
Years ago, I read (probably in Science News) that viruses can’t survive long outside their hosts. That implied any surface onto which a sneezed-out germ found itself — such as the arm of a chair, kitchen counter or car-door handle — would effectively decontaminate itself within hours to a day. A pair of new flu papers now indicates that although many germs will die within hours, none of us should count on it. Given the right environment, viruses can remain infectious — potentially for many weeks, one of the studies finds.

HumansResearchers, journals asked to censor data
Scientists undertake research to advance knowledge. Normally, one aspect of that advancement is to find as broad an audience for the newly acquired data as possible. But what happens if medically important data could be put to ruthless purposes? That question underlies the ruckus developing over two new bird flu papers.
