  Boston MA (SPX) Feb 07, 2017 A giant black hole ripped apart a star and then gorged on its remains for about a decade, according to astronomers. This is more than 10 times longer than any observed episode of a star's death by black hole. Researchers made this discovery using data from NASA's Chandra X-ray Observatory and Swift satellite as well as ESA's XMM-Newton. The trio of orbiting X-ray telescopes found evidence for a "tidal disruption event" (TDE), wherein the tidal forces due to the intense gravity from a black hole ca ... read more |

New research indicates that Baltic hunter-gatherers were not swamped by migrations of early agriculturalists from the Middle East, as was the case for the rest of central and western Europe. Instead, these people probably acquired knowledge of farming and ceramics by sharing cultures and ideas - rather than genes - with outside communities.
