New DNA stool test almost as good as dreaded colonoscopy

Last year alone, almost 50,000 Americans died of colon cancer, and nearly 150,000 new cases were discovered. In fact, it's the third most common cancer in the US, according to the American Cancer Society. And yet one in every three qualifying Americans doesn't follow colonoscopy guidelines: getting one at age 50 and every decade thereafter.

There may be many factors at play behind so many people not undergoing the procedure, but even for those who simply feel squeamish about it, it's hard to blame them. Colonoscopies are invasive, uncomfortable, and at least for some, downright … Read more

DNA solves one of the Titanic's oldest mysteries

DNA has helped solved a nearly 70-year-old hoax -- one that has haunted a family and its ancestors in the debacle over the identity of a girl who was said to have died on the Titanic.

When the massive ship struck an iceberg more than 100 years ago, it was believed that only one child from the first class died in the sinking ship: Loraine Allison. The 2-year-old apparently didn't get safely on a life boat because her parents were said to have been frantically searching for her little brother, who unbeknownst to them was already on a life boat. Allison and her mother's body were never found in the ship's wreckage. … Read more

IBM's 5 in 5: The five ideas that will change your life

Imagine doctors using your own DNA in diagnosing and treating you for everything from cancer to heart disease to stroke. According to researchers at IBM, that technology, now in use in just a handful of cases, will become common practice in the next five years.

IBM researchers included DNA sequencing and other ideas on their annual "5 in 5" list this year. It's a list of what they call the five "innovations that will change the way we live" in the five years to come.

The theme of this year's list (below) is "in the future everything will learn." … Read more

DNA analysis uncovers genetic errors behind 12 major cancers

Thanks to recent advances in genome sequencing that allow scientists to analyze DNA faster and more affordably than ever before, researchers at Washington University School of Medicine in St. Louis say they have found that many types of cancer are driven by the same genetic mutations.

The scientists have been able to analyze 3,281 tumors to find 127 genes that repeatedly mutate in such a way as to drive the development of tumors in the body.… Read more

Engineers write programming language to help build synthetic DNA

Chemical reaction networks make up an old language of equations that detail how chemicals behave together. Now engineers at the University of Washington are taking this language into the 21st century with a computer program for chemistry that can help direct the movement of synthetic molecules.

This standardized set of instructions on how to "program" how DNA molecules interact in a test tube or cell could pave the way for smart drug delivery systems and disease detectors at the cellular level, the researchers report this week in the journal Nature Nanotechnology.… Read more

Genetic groove: Your DNA profile as a unique song

I've always wanted to have my very own theme song, like a hero in a movie. Now, I do. I just used IDNAtity, an iOS app that mixes a little science with art. It takes information about your genetic makeup, assigns you a genetic code, and then translates that code into musical notes to form a song.

You start by uploading a photo of yourself into the app. Then, you answer a few questions about your hair color, eye color, and whether you have dimples (I don't) and can roll your tongue (I can't). The app does the rest, creating a song you can listen to and share.… Read more

Let it be: Dentist wants to clone John Lennon from tooth DNA

I'm going to give you a free hand. And a free set of teeth.

Whom would you like to bring back to life? Einstein? Beethoven? Genghis Khan?

For Canadian dentist Michael Zuk, there will be an answer: John Lennon.

Zuk, you see, has already bought one of the Beatle's teeth for $31,000. Now, his intention is to take that DNA and re-create the whole Lennon.

Imagine.… Read more
