Hubble Finds Light-Bending World with Two Suns http://rgn.bz/vgZG

A distant planet orbiting two stars, found by its warping of spacetime, has been confirmed using observations from the NASA/ESA Hubble Space Telescope. The planet’s mass caused what is known as a microlensing event, where light is bent by an object’s gravitational field. The event was observed in 2007, making this the first circumbinary planet to be confirmed following detection of a microlensing event.

The majority of exoplanets detected so far orbit single stars. Only a few circumbinary planets — planets orbiting two stars — have been discovered to date. Most of these circumbinaries have been detected by NASA’s Kepler mission, which uses the transit method for detection

As I understand it, there have been healthy, thriving vegetarians and vegans for as long as there have been humans. Some were so due to moral or ethical concerns, others due to resource utilization issues, others due to cultural taboos. All other factors being equal, the veg(etari)ans have thrived, and continue to do so. For some more recent historical examples of vegans, we can look at Pythagoras, the "Pythagoreans" (as vegans were called for the following 1300 years), along with a plethora of like-minded contemporaries (e.g. goo.gl/lgDBL ). Buddhists, Jainists, et al., have been doing grand as veg(etari)ans since around the 6th century BCE. Prior to this, there's compelling reason to believe that most people were veg...
