Enceladus Rains Water on Saturn
New observations from the ESA's Herschel space telescope have revealed that Saturn's moon Enceladus expels water from a collection of jets at its southern polar region, forming a giant torus of water vapor surrounding Saturn and becoming the only moon known to influence the chemical composition of its planet.

Ancient "Frankenstein" Insect
Fossils of ancient "Frankenstein" insects have been discovered in Brazil that contain attributes of many diverse modern insect species, such as dragonfly wings and body segments, praying mantis forelegs and mayfly wing veins -- requiring the creation of a new order, Coxoplectoptera.
