Ancestry of polar bears traced to Ireland

An international team of scientists has discovered that the female ancestor of all living polar bears was a brown bear that lived in the vicinity of present-day Britain and Ireland just prior to the peak of the last ice age -- 20,000 to 50,000 years ago. The research is expected to help guide future conservation efforts for polar bears, which are listed as threatened under the Endangered Species Act. The research team concluded that all living polar bears trace their maternal ancestor to a brown bear that lived near present-day Britain and Ireland just prior to the last ice age.An international team of scientists has discovered that the female ancestor of all living polar bears was a brown bear that lived in the vicinity of present-day Britain and Ireland...

Most distant quasar found

This artist’s impression shows how ULAS J1120+0641, a very distant quasar powered by a black hole with a mass two billion times that of the Sun, may have looked. This quasar is the most distant yet found and is seen as it was just 770 million years after the Big Bang. This object is by far the brightest object yet discovered in the early Universe."This quasar is a vital probe of the early Universe. It is a very rare object that will help us to understand how supermassive black holes grew a few hundred...
