isolate

When Kawoaka exposed ferrets to this viral isolate, 100% died.

Kawoaka told The Times in an interview that the mutations seen in this particular isolate have appeared elsewhere in past outbreaks in birds and mammals, “so in that sense, it’s a very orthodox mutation.”

The isolate in the Canadian teen has not yet been genetically sequenced — so it is unclear if it carries these mutations, or others.

Fortunately, that isolate has not been seen since it appeared in that one Texas dairy worker.

In this case, he said, AI was “really like an editing tool” that enabled the Beatles to isolate a John Lennon vocal recording from the late ’70s “that was previously maybe unusable.”
