This was one of the most innovative new developments I've seen in decades. You all know how you get junk spam "Hi I am King Mbumbawawa from Nigeria, I want to send you 100 million dollars but I need your help" spam. A lot of the time your email service catches the worst ones and dumps them into Spam folders.
But some researchers decided to try those ideas looking for ways to help cure ... wait for it... Biological Viruses. That is pretty cool. To re-adapt the tech that picks up Nigerian Scams and send it to pick up HIV strains is pretty neat. I sure as **** didn't see that app.
