Before you request a paternity test, spend a few minutes looking at your child's eye color. It may just give you the answer you're looking for. According to Bruno Laeng and colleagues, from the University of Tromso, Norway, the human eye color reflects a simple, predictable and reliable gen...Rising ocean temperatures, pollution have oysters in hot water

Project BioShield has $5.6 billion to spend by 2014 on drugs to be stored in what is known as the strategic National stockpile.
