A simulation of galactic growth shows how a galaxy akin to our own Milky Way might have appeared 10 billion years ago.

I have always been startled and fascinated by the sandlike abundance of galaxies sprinkled across the night sky. The most sensitive optical image ever made by human beings, the Hubble Ultra Deep Field, captures some 10,000 galaxies in an area about 1/100th the size of the full moon

Nursing homes are unnecessarily administering powerful antipsychotic drugs to many elderly residents, including residents with dementia [1] , according to a new report by the Health and Human Services inspector general. The Food and Drug Administration in 2005 mandated that drug makers issue warning labels [2] on atypical antipsychotics, noting that the drugs--which are generally FDA-approved for treating schizophrenia and bipolar disorder--increase the risk of death for elderly patients with dementia.
