What can DNA Ancestry Tests Really Tell You? A lot of DNA companies are now offering ancestry testing so you can find out more about your ancestors. Overall they can be useful if you have a specific question. But for an overall look at your family's history, they tend to fall short. Let's look at […]
On Tuesday, December 4th, 9-11AM PT, KQED's Forum goes on a live remote to The Buck Institute for Age Research in Marin County to look at the future of aging. QUEST explored the topic of age research on our Eat Less, Live Longer? TV story and Quest for Longevity radio report . The program will […]
Image source: Chris 73If you could know more about your DNA, would you want to? And if you want to know more, is now the time to find out? You might think so given the flurry of company launches in the last few days. These companies promise to help "decode" your genetics (deCODEme). Or reveal […]
Many people spend their holiday seasons inside shopping malls. More and more, kids, in particular, are passing up the opportunity to play outdoors during the rest of the year too. The trend could be contributing to serious health risks such as obesity. And so a movement of parents, teachers and lawmakers is trying to get […]
A growing number of parents, children's advocates and political leaders are worried that our culture's disconnection from nature is harming kids. Concerns about long-term health consequences like obesity have spawned a movement to "leave no child inside."
It has been nine days since a Chinese freighter hit the Bay Bridge spilling 58-thousand gallons of bunker fuel into the Bay. After a massive effort only 25 percent of the oil has been cleaned up. And experts say they may not be able to recover much more. As clean-up crews in hazmat suits scour […]

Bobby is more likely to be gay than Greg. Last blog I talked about some studies that link homosexuality and genes. The most powerful studies are those that compare identical twins to fraternal twins. These studies show that both twins in an identical pair are more likely to be gay than are both twins in […]
Gay Pride Parade in BrazilA big federal study is underway to identify the specific DNA changes that contribute to being a homosexual. Note that scientists are not investigating whether or not being gay is genetic. The evidence is already pretty strong at this point that there is a genetic component to being gay. What they […]
original image from flickr user "Nemo's great uncle" Three years ago, I joined a small group at the Academy of Sciences named the Greenteam. Little did I know that green issues would be such a hot topic today because of global warming. Many people feel that little to nothing can be done about turning back […]
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. This year, an effort to get healthy foods to the school lunch table is tied up in a much larger […]
We've all heard the latest health advice: avoid transfats. Eat more fruits and vegetables. But for many school children, their cafeteria lunch menus haven't caught up. This year, an effort to get healthy foods to the school lunch table is tied up in a much larger debate– national farm policy.
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, […]

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. Now, local community groups are working with the Port and local regulators to change that. You may listen to […]
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.
The human brain was once a black box, but scientists are finding ways to peer inside and explore some of our most complicated thought processes. Using MRI scanners in innovative ways, Stanford scientists are learning how children's brains process words when they read.

"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 […]
