Washington, DC, USA. Because strong evidence indicates that policies beyond the health sector have substantial effects on people's health, all levels of U.S. government should adopt a structured approach to considering the health effects of any major legislation or regulation, says a new report by the Institute of Medicine (IOM).
In addition, federal and state policymakers should review and revise public health laws so that they adequately address current health challenges.

New York, NY, USA. Scientists long have known that neurons generate from neural stem and progenitor cells ( neurogenesis) throughout adulthood in the hippocampus of the mammalian brain.
Now researchers have found that under stressful conditions, neural stem cells in the adult hippocampus can produce not only neurons, but also new stem cells, stockpiled for possible later neuron production when conditions become favorable.

Lancaster, PA, USA. It’s an old political proverb: no one runs for vice president except everyone running for president. Okay, we made up that last part.
The actual adage is shorter: no one runs for vice president. But that is patent nonsense. Although they’ll deny it to the bitter end, presidential candidates often end up hoping their party’s nominee will pick them to run as vice president.

Fairfax, VA, USA. One could say that a transsexual’s person is her whole being, a thing apart for a transgender. [N1] Therein the difference between the two.
Political gender activists would have you not read this. If they could, they would forbid me to write the preceding paragraph. After all and at the very worst, men and women born transsexual are only God’s second mistake.

Knoxville, TN, USA. Mate choice, competition, and the variety of resources available are the key factors influencing how a species evolves into separate species.
A new mathematical model that integrates all three factors to reveal the dynamics at play, in a process called sympatric speciation, appears in the Journal of Evolutionary Biology.
