Before he walked into an honors communications course at West Chester University, Grant Hubbard's ethnic identity was the stuff of skin color and oral history.

He was the white guy with European roots whose family came to the United States shortly after the Mayflower arrived.

Then science took over.

The swipe of a cotton swab inside his cheek and a DNA test indicated that he had ancestors from Europe, and elsewhere.

"My results came back 60 percent Southeast Asian," said Hubbard, 20, of Downingtown. "That's quite a bit different from what my family had always thought we were."

Hubbard is among 350 students who have participated in professor Anita Foeman's DNA Discussion Project, a course at the Chester County school that takes a scientific look at each student's genetic makeup.

The class is an effort to look at diversity in a way that shows connections instead of differences. Students set up websites and write papers about the results.

"It's much harder to totally write somebody off when you realize that 'I have some of that in me as well,' " Foeman said.

The results often shock students, prompting them to reexamine their identities, question their relatives, and start researching family history.

One person's trash may be another person's treasure, but sometimes, trash is just trash.

So-called junk DNA, the vast majority of the genome that doesn't code for proteins, really isn't needed for a healthy organism, according to new research.

"At least for a plant, junk DNA really is just junk it's not required," said study co-author Victor Albert, a molecular evolutionary biologist at the University of Buffalo in New York.

While the findings, published Sunday in the journal Nature, concern acarnivorous plant, they could have implications for the human genome as well. Genes make up only 2 percent of the human genome, and researchers have argued in recent years that the remaining 98 percent may play some hidden, useful role.

Trash or treasureFor decades, scientists have known that the vast majority of the genome is made up of DNA that doesn't seem to contain genes or turn genes on or off. The thinking went that most of this vast terrain of dark DNA consisted of genetic parasites that copy segments of DNA and paste themselves repeatedly in the genome, or that it consists of the fossils of once useful genes that have now been switched off. Researchers coined the termjunk DNAto refer to these areas.

"Nobody's really known what junk DNA does or doesn't do," Albert told LiveScience.

But in recent years, researchers have debated whether "junk" might be a misnomer and if this mysterious DNA might play some role. A massive project called ENCODE, which aimed to uncover the role of the 3.3 billion base pairs, orletters of DNA, in the human genome that don't code for proteins, found that in test tubes, about 80 percent of the genome seemed to have some biological activity, such as affecting whether genes turn on. Whether that translated to any useful or necessary function for humans, however, wasn't resolved.

'Junk' DNA mystery solved

LEAMINGTON SPA, U.K., May 13, 2013 /PRNewswire/ -- DNA Dynamics, Inc. (OTC PINK:DNAD) announces that it has been chosen by a large digital PC Publisher to bring one of its hugely successful PC games to the mobile space.

The game, which was unveiled in May 2010 and released in 2011, is a Real Time Strategy PC game and was the latest installment on a prestigious series which has an incredibly strong and loyal fan base globally. Now, DNA Dynamics, Inc. has been commissioned to pick up this complex game and port it to iPad and Android Tablets. The contract, which we are currently delivering via a Non-Disclosure agreement, will ensure that DNA will be writing good revenue in the first 2 quarters of 2013.

Ed Blincoe, commenting on the contract signing said "...having only just begun the new work for hire initiative having a contract signed so quickly is evidence that the company's new strategy is already working. Taking on as prestigious piece of IP is a huge honor for us."

DNA was commissioned to undertake this port after an extensive pitching process, which ended with DNA being successful in winning the contract.

DNA Dynamics, Inc. has recently undergone a strategy re-evaluation and has moved away from developing its own IP and is focusing on writing revenue through work for hire with third party publishers.
