Syyn Labs lights up Glow festival | 89.3 KPCC

Kim Nowacki/KPCC Syyn Labs' "DNA Sequencer" lights up Santa Monica's Crescent Bay Park during the "Glow" festival on Sept. 25, 2010. The yellow caution tape wasn’t much of a deterrent for people who slid under it’s flimsy border to get a closer look at the “DNA Sequencer,” one of the flashier illuminated art installations that made up Santa Monica’s sprawling Glow festival this past Saturday. By day, the piece was a tangled mess of plywood, old-school ribbon wire and Arduino programming boards. By night, the installation’s 512 individually controlled LED lights had been [more...]

Interview with Arun Kumar: Genographic Postdoc, India - Genographica

I have worked with state of the art DNA technologies like Taqman assays, Fragment Analysis and DNA sequencing and have gained a true global experience working with on the Genographic team. Everyday brings a new learning experience! GP: Wait a minute, for those of us that aren't scientists, what is an assay? Arun Kumar: An assay is a way to genotype a specific mutation within DNA. In other words, it is an experiment that helps to identify a specific nucleotide with Y chromosome or mitochondrial DNA. This mutation will define the ancestral or derived state which will help to identify the [more...]

Obsessed With Genes (Not Jeans), This Teen Analyzes Family DNA ...

The Wests signed up in 2007 and gave 23andMe genetic testing as Christmas presents to family members. From that experience, Mr. West learned that Anne also inherited the mutation on the Factor V gene that increases the risk of a pulmonary embolism. He wanted to know more. By last year, whole genome sequencing was not only being offered to individuals, but the price had dropped enough that Mr. West raised the idea at dinner. “Dad got curious about the whole family,” Anne says.

DNA test favors Va. man convicted of rape - Maryland Daily Record

DNA tests conducted under Virginia’s one-of-a-kind post-conviction DNA testing program indicate that a man who served seven years in prison for a 1979 rape didn’t commit the crime, and he wants Virginia’s high court to declare him innocent. Calvin Wayne Cunningham would be the eighth man exonerated by decades-old biological evidence and the third since Virginia began its massive project to clear those who may have been wrongly convicted in the 1970s and 1980s from biological evidence saved before DNA testing was available. Cunningham, 57, was convicted in 1981 of raping the [more...]

Do you want to live forever? Scientist may have figured out how…

The ends of the chromosomes are capped by telomeres, long thought to have a protective function. Without them, the chromosomes would be shortened during each cell division, because DNA polymerase is unable to copy to the very end of one of the two DNA strands it is replicating.       In the early 1980s, after their fortuitous meeting at a Gordon Research Conference in 1980, Blackburn and Szostak discovered that telo­meres include a specific DNA sequence. Fired up by the novelty of each other's work, they devised experiments that seemed crazy at the time, even to themselves. Szostak took [more...]

Thus, although long RNA fragments are non-coding transcriptome most mammals, their cellular functions are still unknown. Scientists have already described the role of small RNAs in gene regulation but we still know very little about the long fragments .

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...]

Many people regard shared DNA sequences as the best evidence for evolution and common descent.

These types of studies indicate that evolution’s best evidence may not support it at all. Horizontal gene transfer could be a consequence of some other type of mechanism, like parasite-mediation.
