Gay Genes? part deux

Gay Genes?

Gay Pride Parade in BrazilA big federal study is underway to identify the specific DNA changes that contribute to being a homosexual.

What's for Lunch

We've all heard the latest health advice: Avoid transfats. Eat more fruits and vegetables. You may notice those changes on grocery store shelves, but for many school children, their cafeteria lunch menus haven't caught up.

Would a gene doper get an asterisk?The last few blogs I have been talking about people adding genes to their DNA to make them better athletes. The reason they're considering this sort of gene doping instead of just taking a designer steroid or two is that a DNA change will supposedly be more permanent, safer, […]

Perilous Diesel

Much of what we eat and buy comes through the Port of Oakland, the fourth busiest port in the country. But at what cost? Nearby residents have some of the highest asthma rates in the state.

Your tennis shoes. That radio you're listening to. If it wasn't made in the U.S., chances are it passed through the Port of Oakland, the fourth busiest Port in the country. But there's a downside to that convenience and those affordable prices, as Amy Standen reports.

"We can rebuild him. We have the technology." Remember that opening line from the Six Million Dollar Man? Soon we'll be able to genetically rebuild people. Or at least add some cool new features… Let’s say we wanted to make an athlete stronger or able to run for a longer amount of time. One way […]

Scientists are discovering ways to make animals live dramatically longer through calorie restriction — a diet that requires eating at least 30 percent fewer calories than normal. QUEST investigates why we age and what the societal costs are for living well beyond 100.

Living in the bay area with two school-aged sons, you'd think the news that Barry Bonds broke the all-time home run record would have been a big deal in our house. It wasn't. My kids focused on the steroids instead of home run number 755. This got me to thinking about fair and unfair advantages […]
