The new study suggests that genetic variation explains more than half of the variation in dog ownership, implying that the choice of getting a dog is heavily influenced by an individual's genetic make-up.

Hubble Spies a Galaxy Deformed and Rejuvenated by a Near Collision

A cosmic hit-and-run some 30 million light-years away has left one galaxy with an identity crisis. For billions of years, the now-irregular NGC 4485 lived a nice and normal life as a standard spiral galaxy located in the constellation Canes Venatici (the Hunting Dogs). Then, a few million years back, NGC 4485 experienced a near-miss when the equivalent of a galactic semi-truck (NGC 4490) careened
