The intense gravity of a supermassive black hole can be tapped to produce immense power in the form of jets moving at millions of miles per hour. A composite image shows this happening in the galaxy known as 4C+29.30 where X-rays from Chandra (blue) have been combined with optical (gold) and radio (pink) data. The X-rays trace the location of superheated gas around the black hole, which is estimated to weight 100 million times the mass of our Sun.

The Great Recession, characterized by devastating mortgage defaults, has challenged the conventional wisdom that home ownership is a good investment, particularly for those with low and moderate incomes. But the conventional wisdom on the benefits of owning vs. renting still holds when done right, according to a newly published study led by the Brown School’s Center for Social Development at Washington University in St. Louis.

Mice engineered to be lacking the Ggamma13 protein in their olfactory receptors were functionally anosmic – unable to smell. The findings may lend insight into the underlying causes of certain smell disorders in humans.

The paper was published today in the online edition of Nature.
