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 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.
