Study reveals critical factors affecting urban pollution
A critical factor affecting ozone concentrations in American cities is beyond the control of local regulators -- the amount of ozone drifting into a city from outside its boundaries.

Blood vessels found to signal chain of destruction in bone diseases
Biologists at Washington University in St. Louis have discovered a mechanism in blood vessels that opens the door for bone loss in such diseases as rheumatoid arthritis, periodontal disease, osteoporosis, tumor-associated bone loss, or artificial implant loosening.
