EXCELLENT!!!

It is reported that a German physician has CURED HIV infection in a patient by performing a bone-marrow transplant from a donor possessing natural immunity.  HIV immunity is conferred by a genetic mutation that appears to originate from Northern Europe during the Middle Ages.  Individuals with two copies of the mutant gene, one from each parent, have immune cells without CCR5 receptors, which cannot be infected by HIV.  Individuals with a single copy of the gene are not immune, but have greater than normal resistance to HIV infection.

Dark forces at work

This XKCD strip, and the "dark flow" astronomical discovery it reports, raise a very interesting issue.

Current conventional wisdom in physics says that the gravitational force is carried by a particle of some kind, and propagates no faster than C.  Conventional wisdom in physics also says that because of this, objects beyond the edge of the observable universe cannot affect us gravitationally, as gravitational force carriers from them can never reach us (any more than their light can).

If every galaxy we can observe, regardless of direction, is being pulled towards one region of the sky, and if this is the action of a supermassive object beyond the edge of the observable universe, it would imply that the conventional wisdom is not the case, and gravity is not in fact limited to the speed of light.

To say the least, the possible implications of this revelation would be interesting.
