NZ bird 246x178 custom DNA Brings Bird Species Back to LifeFor the last 150 years, the New Zealand storm petrel bird was thought to be extinct. Recent DNA evidence, however, has proven common knowledge wrong: the bird still flies.

In 2003, birdwatchers Ian Saville and Brent Stephenson observed a bird that looked different from the common storm petrel they were so used to seeing. This aroused the birdwatching community, and since then, there have been several other sightings. Before long, some began to speculate that this strange bird was in fact the New Zealand storm petrel, an animal long considered extinct.

Researchers took to DNA testing for confirmation. The University of Otago’s Bruce Robertson extracted DNA samples from tissue fragments of New Zealand storm petrels preserved in three museums in England and France. He then compared these with samples from birds suspected to be New Zealand storm petrels that have been caught in recent years. The results matched up and speculation was proven true: the bird is not, and has never been, extinct.

The bird was once commonly referred to as the “Jesus bird,” because of its habit of slapping the water it swims over with its feet. Already known for “walking” on water, now the New Zealand storm petrel has another trait in common with the famed religious figure: its ability to rise from the dead. And without DNA testing, its rebirth could never have been official.

What are your thoughts on the New Zealand storm petrel? Do you expect to see more “extinct” animals return in the future? Leave your comments below. And for all your DNA news, make sure to visit the GTL DNA testing blog.

One of the largest international sperm banks in Denmark, Cryos International, has released a statement turning away sperm donations from redheaded sperm donors. Unfortunately Cryos explains that the supply is currently exceeding the demand.

christina hendricks 235x300 Gingers Are Out: Sperm Bank Rejects Redheads

Christina Hendricks from Mad Men - The famous redhead gained her notoriety from her ginger locks.

According to the Cryos agency director, Ole Schou, the long waiting list of redheaded candidates accompanied with their current supply of 140,000 doses of sperm from redheads creates a situation where, “Our stock is about to explode.”

“There are too many redheads in relation to demand. I do not think you chose a redhead, unless the partner — for example, the sterile male — has red hair, or because the lone woman has a preference for redheads. And that’s perhaps not so many, especially in the latter case,” Schou also stated.

Because Cryos International supplies to 65 countries all over the world, sperm donors with genetic characteristics that are unwanted will cause a suspension in donations. Redheads are not alone in this; Schou explained that the bank is also not taking donations from non-brown-eyed Scandinavians.

It must be shocking to find out that your genetic makeup is currently “unwanted.” Redheads should not take this too hard; there are sperm banks all over the world who are announcing they are glad and willing to take donations from redheaded donors. There is also still a high demand for redheads in Ireland.

Parents who are choosing less traditional ways of reproduction, for whatever reason, now have the ability to pick and choose the DNA of their child. For this reason the most desirable sperm comes from educated athletes or musicians.

Who can forget the vanity in the world we live in? As much as skills and intelligence comes into play, looks take precedence as well. Unfortunately the demand for Cryos leans away from redheads. Cryos explains that the demand in Europe is for brown hair, brown eyed men.

Cryos also wants to represent the other countries outside of Europe that they supply to.

“Our function in society is to have all races and all ethnicities. Our problem is that we have too many Scandinavians only,” Schou added.

If you think about it most people want their children to look like them and because redheads are rarer in society, the likelihood that the demand would reflect that is high.

How do you think this will affect redheads of the future? Just four percent of the world’s population carries the red-hair gene. The ginger gene is recessive and gets diluted when DNA is combined with more dominant genes like brown-hair.

Are the rumors true?!

The world was shocked and excited when Beyonce announced her pregnancy last month at the MTV Video Music Awards; Jay-Z & Beyonce are going to be parents for the first time …or are they?!

The music world is spinning right now with rumors of Jay-Z’s secret love child. Sources say that Jay-Z secretly fathered a child nine years ago with Shenelle Scott, a video model he was sleeping with her at the time she got pregnant. The only thing missing is verifiable DNA evidence.

According to the NY Daily News:

Jerald Andrews, a man who once thought he was the boy’s grandfather, told Star Magazine that DNA tests proved definitively that Jay-Z was the dad of the now 9-year-old tyke.

But when contacted Wednesday by The Daily News, Andrews, 67, denied having any first-hand knowledge there was a DNA test.

To further prove his point, Andrews went on to proclaim that the boy looks nothing like Malik Andrews, the boys’ supposed father.

Other sources say that the Jay-Z gave Shenelle Scott $1 million to “keep her mouth shut” and that the rapper also pays for child support.

9 11 dna 2011 DNA Testing: Human Remains from 9/11 Matched Ten Years Later

Virtually a decade after the terrorist attacks of 9/11, forensic scientists are still attempting to identify the remains of over 1,000 of the nearly 3,000 victims who died in the World Trade Center attacks.

Just a few weeks ago, on August 23rd, 2011, NYC’s medical examiner announced its successful DNA matching of Ernest James, a 40 year old New York resident who had been assumed dead by family and friends in the Twin Towers’ attack.

James’ worked the night shift in the information technology field at the World Trade Center. Ernest James normally called his fiancée, Monique Keyes, in the mornings after every shift. Keyes said after the attacks, “When I couldn’t reach him, I pretty much, deep inside, knew.” Now, ten years later, the news of his matched DNA test has finally brought her some closure- right in time for the anniversary of this tragedy.

The medical examiner’s office plans to continue testing remains found in the rubble of the World Trade Center, despite the challenges they are dealing with. Typical DNA identification techniques had to be re-developed in order to successfully identify victims whose remains were too damaged to detract DNA in the normal fashion.

NewScientist.com confirms, “Complete DNA profiles can be generated from human remains and compared against DNA from relatives. But partial profiles were often the best that could be created from much of the flesh and bone from the Twin Towers”.

Despite this, forensic technicians are still hard at work trying to give a bit of closure to those families of 9/11 victims who have not yet been identified.

DNA Spray 300x234 DNA Spray Makes Burglars Think TwiceThere’s nothing like an invisible weapon.

And that’s exactly what a SelectaDNA, a new DNA spray being used in select countries across the globe, is. The spray, developed by British company Selectamark, is simple. It is installed so that when robbers break into a store, employees can push a button that sprays it from a number of locations. The clear mist is so fine that those sprayed do not even feel it, but it stays on their skin and hair for weeks or even months. Thus, the criminals who commit the crime are “marked,” which certainly comes in handy down the line in court.

The spray, developed in 2008, is used across many European countries, and recently has been installed in New Zealand and Australia. According to AOLnews, Selectamark is in talks with US companies as well. Stores who use the spray display a sign in their front window that warns criminals, in various languages: “You steal, you’re marked.”

Andrew Marks, the managing director of Selectamark, explains how the spray cannot just be washed off. “It will come off within a number of hand washes,” says Marks. “But if you run through a spray it will accumulate in the inside of your nostrils and ears and under the fingernails; areas that are difficult to get off.”

That being said, the main purpose of the spray is actually not to be able to catch criminals more effectively; officials hope that, in the long run, this will prevent crime before it happens. And so far, so good. Between January and May of 2010, during Selectamark’s test run of the spray, crime in West London, where it was tested, fell off by 65%. And one can only imagine that, the more potential criminals hear about this technology, the less likely they will be to try to test it.

Innocent bystanders need not worry about the spray either. The spray cannot be used to identify a suspect, but rather it can only be used to as evidence for an already-existing suspect. And, we might add, it is pretty good evidence too.

According to Jason Brown, the business director of Selectamark, “The word DNA spreads fear into even the most hardened criminals.” We can only hope Brown is right. The early results, encouragingly, look good.

What do you think about this DNA spray: will it continue to work? Or will criminals find a way around it? Sound off in the comments below. And for more DNA information, please visit GTLDNA.com.
