    1. Why hantavirus takes so long to show symptoms and what that means for containment | People exposed to the Andes strain of the hantavirus may not develop symptoms for up to 42 days, a delay that makes tracing infections more difficult

    3. Not alive, but not dead: disembodied human brains used for drug testing
