Scientists Revive a Giant 30,000 Year Old Virus From Ice

Posted by samzenpus on from the I-saw-this-movie dept.

bmahersciwriter writes "It might be terrifying if we were amoebae. Instead, it's just fascinating. The virus, found in a hunk of Siberian ice, is huge, but also loosely packaged, which is strange says evolutionary biologist Jean-Michel Claverie: 'We thought it was a property of viruses that they pack DNA extremely tightly into the smallest particle possible, but this guy is 150 times less compacted than any bacteriophage [viruses that infect bacteria]. We don't understand anything anymore!'"

  1. 30,000 years old? by Zaiff+Urgulbunger · · Score: 5, Insightful

    I'm surprised this thing is very different to modern viruses given that it's *only* 30K years old. I appreciate these things are always evolving, but I would've thought they'd have done most of their evolving in the previous 3-billion years or whatever. So presumably, being big wasn't a problem for a virus until relatively recently?
