Rulers of Ancient Egypt’s Enigmatic Hyksos Dynasty Were Immigrants, Not Invaders
New research led by Bournemouth University archaeologists supports the theory that the Hyksos, the rulers of the 15th Dynasty of ancient Egypt, were not from a unified place of origin, but Western Asiatics whose ancestors moved into Egypt during the Middle Kingdom, lived there for centuries, and then rose to rule the north of Egypt.

Hunting dark matter with GPS data
A team of physicists has used data from GPS satellites to hunt for dark matter, the mysterious stuff whose gravity appears to hold galaxies together. They found no signs of a hypothetical type of dark matter, which consists of flaws in the fabric of space called topological defects, but they say they have vastly narrowed the characteristics for how the defects—if they exist—would interact with ordinary matter. Their findings show how surprisingly innovative—and, in this case, cheap—methods might be used to test new ideas of what dark matter might be.
