1. Muller’s ratchet; “splice together parts, make a new version” “Following section on the New Tab page” “will continue to strengthen extremists“
2. Vaneless ion wind generator; “Painting tree trunks white a time honored method of young tree protection” “reach the ability to be work optional“
3. Halcyon; Orbital — Halcyon On and On; “a matter of who was taking advantage of who” “its first robotic laboratory on Mars” “Ginoong Pangulo“
