As the baseball season winds down and the football season is poised (hopefully) to begin, it's interesting to think about why some people become professional athletes and others don't. It's not just a matter of talent and determination--it also involves having the right GENES. In other words, what's more important: nature or nurture?

Forensic scientists are discovering that DNA and "genetic markers" can predict who will--or will--turn to a life of crime. If this is true, it portends a frightening future where we give infants DNA swabs, then decide whether to watch them (or even incarcerate them) for the rest of their lives. Since more black men are jailed in the US...

Our minds may be modern but our genes
are prehistoric, which is the reason we have so much trouble losing weight! In addition to fast food, desk jobs, and inertia, there is one more thing to blame for unwanted pounds-our genome, which has apparently not caught up with...

In the future
, you may be able to forgo exercise and still stay healthy, by having your genes tweaked instead. By tweaking a single gene, scientists have mimicked in sedentary mice the heart-strengthening effects of two weeks of endurance...

Only God can create life?or will we soon be able to do ittoo? Roland Pease writes for BBC that for the first time,U.S. researchers have created a form of artificial life.Their creation is nothing more than a group of crudebiological cells at the moment, but this could be the firststep in creating real life.
They made the cell walls from...

You may be able to blame some of your unhealthy habits on our genes. Everyone has one of two genes that cause them to either taste, or not taste, a certain bitter substance. The ability to taste these substances developed long ago, to protect people living in places where bitter tastes were a way to identify poisons. Today, the ability to taste?or...

Maybe you like warm weather and hate the cold, or maybe you feel great during a brisk winter day. Scientists think that whether you'll be happier in Florida or Vermont is encoded in your genes. And if you're living in the wrong climate for your genetic makeup, it can make you get fat.
Geneticist Douglas Wallace found that these genes are...

Scientists have been able to double the life spans of fruit flies by manipulating one of their genes. Someday soon, they may be able to do it for us. Scientists have named the gene INDY for "I?m Not Dead Yet."
Flies with a mutation in the INDY gene have lived for 71 to 110 days, more than twice as long as their usual life span of 37 days...
