They identified genetic markers that are "most different" between centenarians and randomly selected individuals.
And it doesn't require any knowledge of what the genetic markers being tracked do.
Today's procedure is a skin biopsy that will be used to study the genetic markers in their subcutaneous fat.
Diadexus and its competitors plan to patent genetic markers they find and to sell their tests at a premium.
Using a computer algorithm, the researchers focused on identifying unique genetic markers on the Y chromosome of men in the project.
Unlike some other diseases, however, clear genetic markers for coronary heart disease, which accounts for 1 in 6 U.S. deaths, remain elusive.
So far, its scientists have identified 600 genetic markers in ten species of eucalyptus, acacia and melaleuca, a temperate tree prized for its oils.
It contains only 13 genetic markers, known as "junk markers, " that were specifically chosen because they are not correlated to any physical or medical traits.
The work also confirms that 31 variants previously linked to the developmental disorder may serve as useful genetic markers for identifying those with the condition.
Much still remains unknown about the virus, including how people are getting infected, but scientists say it contains genetic markers that could help it infect humans.
Instead, we need to identify the genetic markers that can be linked to drugs that have been known to respond to patients with those specific genetics.
The DNA samples used to identify a "true" wildcat include a Victorian specimen kept in the British Museum - providing a sample with 63, 000 genetic markers.
Then, when you mate two trees with different desirable properties, it is simple to check which offspring contain them all by looking for the genetic markers.
ECONOMIST: Genetic engineering: Gone is the forest primeval | The
Henry Amerson, also at North Carolina State University, is using genetic markers too, this time to breed fungal resistance into southern pines such as the loblolly.

If the safety of the student athlete is paramount, it seems better to simply demand the testing, not just for sickle cell but other life-threatening genetic markers.
FORBES: The Devilish Details Of The NCAA's New Genetic Testing Rules
Sixteen of the 23 newly identified genetic markers are associated with aggressive forms of the disease so may help clinicians and patients decide on the best form of treatment.
That focused the search still further and the team was then able to employ more modern methods using genetic markers to show which small fraction of chromosome 16 the apomixis genes inhabit.
Areas for potential research include a search for genetic markers which could reveal a susceptibility to particular types of brain trauma, as well as developing more defined and consistent management and treatment protocols.
If genetic markers can also help resurrect drugs that have previously failed tests by screening out unsuitable candidates in a fresh trial, some genome firms may well claim a big chunk of the proceeds.
The main advantage of using genetic markers is that it speeds up old-fashioned breeding methods, because you no longer have to wait for the tree to grow up to see if it has the desired traits.
ECONOMIST: Genetic engineering: Gone is the forest primeval | The
As a first step, the scientists examined half a million genetic markers in the participants' DNA. These markers, known as single nucleotide polymorphisms, or SNPs, can together reveal how genetically similar people are, even though they are not conventionally related.
Genetic markers for the bacterium were sent to America and the Animal and Plant Health Inspection Service confirmed in July that the same form of Candidatus had been found in potatoes from two fields in Texas that were exhibiting zebra-chip symptoms.
In non-small cell lung cancer, for instance, the tissue samples needed to identify these genetic markers are not routinely taken for practical reasons, says Mark Kris , an oncologist at Memorial Sloan-Kettering Hospital in New York who has worked with Iressa and with OSI's Tarceva.
The theory goes that symmetrical features may be markers of genetic quality.
Just because you have one or two markers of genetic risk does not mean that you will definitely develop a particular condition, but the outcome can be affected by changes in lifestyle, or in some cases, by taking medication.
Dr White has identified ten microsatellite markers that can be used to build up a unique genetic profile of the individual tree.
By combining the gene test for BRCA1 and BRCA2 with this extra genetic information, women who have a high number of the newly identified markers could find they have a nearly 100% risk of getting breast cancer.
Using these markers, Celera plans to introduce a test next year called the coronary heart disease genetic risk score.
