It’s all true! He was right! He was totally, hopelessly wrong about selfish genes, but he was right about memes. Well…he was a little bit right. He was wrong to equate the evolution of memes to the evolution of organisms, meme evolution being Lamarckian in character. But he was right to point out the potential capacity for memes (i.e cultural concepts) to prevent logical thought in the minds of their hosts. To ‘colonise’ those minds as Fred Phillips puts it. Dawkins likes to use religion to illustrate this point, but I prefer his own pet theory of   selfish genes.

The Big Dipper has a secret, invisible to the unaided eye, according to a new paper published in The Astrophysical Journal, which says that one of the stars that makes the bend in the ladle's handle, Alcor, has a smaller red dwarf companion.

Newly discovered Alcor B orbits its larger sibling and was caught in the act with an innovative technique called "common parallactic motion" by members of Project 1640, an international collaborative team that includes astrophysicists at the American Museum of Natural History, the University of Cambridge's Institute of Astronomy, the California Institute of Technology, and
NASA's Jet Propulsion Laboratory.
