In a letter published today in the nation’s two most prestigious scientific journals — Science and Nature — bird flu researchers say they need to perform research on the H7N9 virus that would make it more dangerous.

The researchers say that’s necessary in order to prepare for its possible spread between humans, perhaps as early as this winter.

The paper comes on the heels of a new study in the British Medical Journal that shows the first probable transmission between humans of the H7N9 virus.
