Tribal DNA Test How Different American Indian Tribes Have ...

Generations of American families in the United States sometimes believe that they have Native American blood in their genes. If traditional research methods fail to produce any information, a DNA test may be just the thing you should try.Here are some things you should know about DNA testing and how it may determine which American Indian tribe you belong to:1. A DNA test can determine two of an individual’s many lineages.One way to determine a lineage is the mtDNA or the mitochondrial DNA test, which traces the genetic lineage along the maternal line. The Y chromosome DNA test, on the other [more...]

Science News for Kids: Feature: Scientist Profile: Wally Gilbert

You've won a Lasker Award and a Nobel Prize for your research on sequencing DNA, basically figuring out the order of the letters in this very long word. How does that method work? Fred Sanger in England invented one method, and I invented another with my collaborator, Allan Maxam. The very first piece of DNA we deciphered was only 20 groups long. It took us two years to work out the order of those groups. A typical gene in our body is some ten thousand groups long, so you couldn't possibly work out the entire order of groups for a gene. Then suddenly we discovered a simple way of doing it. It [more...]

The New Tutmania: Considering The Half-Life Of An Afterlife ...

Oct. 13 2010 - 10:19 am | 169 views | 1 recommendation | 1 comment King Tut—lame or not lame? Historical researchers now think that the 1300 B.C. Egyptian boy king was literally lame—among his belongings was a variety of fancy staffs, canes and other walking aids. Apparently he was born with a club foot, possibly as a result of incest among his immediate ancestors. But what about the half-life of his afterlife, as represented by all the gaudy bling and other paraphernalia from his tomb periodically trotted out to wow us hoi polloi? Does it stack up to the ultimate lowbrow carny-sideshow [more...]

Drs. Singh and Lai reported a decade ago that cell phone radiation quickly causes DNA single-strand and double-strand breaks at well below the current federal safety level for exposure. This causes a condition called micronuclei. Dr. George Carlo is a public health expert who conducted wireless technology research. He showed that human blood exposed to cell phone radiation had a 300% increase in genetic damage in the form of micronuclei. He says that wireless technology is “potentially the biggest health insult” this nation has ever seen, bigger than cigarette smoking and asbestos. Even [more...]

Assuming a $350 cost per test, the researchers found that testing stool DNA every three or five years resulted in fewer added life-years and higher costs than the currently recommended screening strategies for CRC. There were no levels of sensitivity and specificity achieving cost-effectiveness at $350 per test, and the researchers calculated that stool DNA tests would not start to be cost-effective until the cost dropped to $40 to $60 per test for testing every three years. The researchers said DNA testing could be cost-effective at $350 per test if adherence were at least 50 percent higher [more...]

Scientists know that the key to unlocking neurological disorders begins with a full understanding of how neurons are generated and sustained.

A new factor in identifying the ancestry of Native Americans is DNA research.

Molecular biologists and geneticists often use DNA microarrays to detect DNA, measure gene expression levels and detect the single-nucleotide polymorphisms that are responsible for various genetic diseases. A DNA microarray has tens of thousands of biosensors on its surface; each biosensor contains a short DNA fragment, known as a probe, for recognizing DNA targets. Ideally, the DNA biosensor should have high sensitivity (the ability to detect very low concentrations of targets), high specificity (the ability to distinguish the difference between similar targets) and high stability (the [more...]

How familial DNA can help crime victims

Using a familial DNA search, the crime lab compared the DNA left at the crime scenes with DNA samples in California's database of 1.3 million felons to search for near matches indicating possible relatives. The familial DNA search turned up 200 partial matches. Researchers then compared the Y chromosome (which is passed from father to son) found at the crime scene to the 200 partial matches. Only one result turned up: Franklin Jr.'s son, who had been convicted of a felony weapons charge. The police subsequently surveilled Franklin Jr. and directly connected him to the serial killings using [more...]

Cheap DNA test diagnoses genetic diseases | TG Daily

Quick, cheap gene tests for many diseases could be just around the corner, with the development of a DNA test that works on a drop of saliva. "This technology offers a speedy, cost-efficient alternative to existing methods of DNA analysis," says Dr Juan Diaz-Mochon of Edinburgh University's School of Chemistry. "Our method could help reach the goal of complete genome analysis in a few hours for less than $1,000." The researchers say that the test, based on chemical analysis, delivers reliable results without the need for expensive enzymes used in conventional DNA testing. It's successfully [more...]

Science Seminar - Ancient DNA

From just a few grams of ancient sediment, it is possible to reconstruct the environment in disparate places at different times. This is possible by extracting total DNA from sediments and looking for the genetic signals of various organisms that contributed to the mix. By comparing the signals with reference databases, identification to genus and species level of plants and animals is often possible. Such information can inform theories of niche stability, extinction dynamics and environmental change, and are therefore complimentary to existing methodologies such as pollen and macrofossil [more...]
