Baltimore, MD (Scicasts) — Researchers at Johns Hopkins have identified a highly sensitive means of analyzing very tiny amounts of DNA. The discovery, they say, could increase the ability of forensic scientists to match genetic material in some criminal investigations. It could also prevent the need for a painful, invasive test given to transplant patients at risk of rejecting their donor organs and replace it with a blood test that reveals traces of donor DNA.
Alana Saarinen is one of just a handful of people in the world who have DNA from three people, thanks to a new infertility treatment that could soon be available in the UK.
Over the past 20 years DNA evidence has become the foundation upon which forensic investigation is built. The identification of traces of blood, saliva and other bodily fluids places a suspect directly at the site of a crime, and can be the difference between a guilty or not guilty verdict in court.
But as new identification technologies emerge at an ever quickening pace, new questions are being raised as to not only the efficacy of these technologies, but also their implications on privacy, civil liberties and validity.
Recently, Corning Incorporated, together with Polytechnique Montreal, is developing a type of smart glass mainly used as the touchscreen of the smartphone, which can detect people’s physical condition and can even analyze the user’s DNA through reading the spit on the surface of the smart glass. Besides, this smart glass can also detect the composition of the atmosphere.
WASHINGTON – The District of Columbia is about to become the first city in the nation to use a revolutionary new crime fighting tool. It is a lab device that can analyze DNA in just over an hour and gives investigators the answers they need in just a fraction of the time it takes now.
SAN DIEGO, July 1, 2014 /CNW/ – Diomics, Inc., a provider of X-Swab™, a novel bio-specimen collection material, reported that its patented technology was used in a new study being published today in the journal Forensic Science International Genetics. The study, “Evaluation of a Novel Material, Diomics X-Swab™, for Collection of DNA,” assessed the ability of X-Swab™ to recover DNA by DNA quantitation and short tandem repeat (STR) typing. The authors conclude that X-Swab™ yielded significantly more DNA and higher average peak heights compared with DNA extracted from competing technologies for both blood and saliva samples, particularly for low quantity samples.
INDIANAPOLIS — A northwestern Indiana police department on Tuesday became one of the first law enforcement agencies in the country to distribute a theft-deterring chemical that leaves DNA-like “signatures” on property and those who attempt to steal it.
Look out criminals. The crime-busting tools of science fiction are becoming a reality. A new forensic test can detect the ethnicity and gender of someone using nothing but a single hair, and in less than two minutes no less, according to a new study.
The study, published in the Journal of Analytical Atomic Spectrometry, details how a new tool designed by scientists has shown a 100 percent success rate in identifying gender and ethnicity using a strand of hair
Sensitive site exploitation is part of SOCOM’s special reconnaissance, surveillance and exploitation program office, where work is conducted to collect biometric and forensic intelligence.
As the Defense Department shifts to a strategy that will rely more on special operators, those conducting sensitive site exploitation missions need new technologies, Fitz said.
GRAND RAPIDS, MI — It was a brutal 1999 rape of a young woman in downtown Grand Rapids.
The case might have been solved years ago, but for an unusual twist in the circumstances of a suspect – he was an identical twin – and DNA technology could not distinguish between the genetic makeup of Jerome Cooper and his brother, Tyrone Cooper. Both were sex offenders
That was then.
Now, science may have advanced enough to solve the case, police say.
A business called the Center for Advanced Forensic DNA Analysis in Greenville, N.C., claims it can look at genetic mutations to determine which brother committed the crime
A new kind of sanitizer spray kills more than just bacteria. Artist and technologist Heather Dewey-Hagborg‘s “Invisible” line aims to wipe all traces of personhood from drooled-on forks, subway poles, and all other objects that hide traces of our DNA long after we’re gone. A product that preemptively erases DNA in order to avoid people spying on your genome might sound paranoid. But Dewey-Hagborg knows just how easy it is to snoop on DNA from experience. In 2012, fascinated by a single stray hair found in a cracked painting, she began collecting cigarette butts, chewed-up gum, and hair samples from public places, analyzing the genetic sequences contained within, and creating 3-D masks generated from the forensic details. The “Stranger Visions” project, she says, drove her deep into the all-too-real debates over genetic surveillance. Now, she’s working on a dissertation on genetic privacy, and gearing up for a sale of the sprays this June.
PITTSBURGH, PA. — Biological evidence is often a DNA mixture of two or more people. Forensic laboratories apply thresholds that simplify DNA data, which can reduce match statistics or discard evidence.
But sophisticated computing better preserves identification information, as shown in a recent study, “TrueAllele Casework on Virginia DNA mixture evidence: computer and manual interpretation in 72 reported criminal cases.” This fifth TrueAllele validation article was viewed a thousand times in one month at the open-access PLoS ONE journal website.
NEWARK — In 24 years, several homicides in Licking County have remained unsolved. One of those cases involves an unidentified woman who has been known only as Jane Doe since she was found.
DEERFIELD BEACH, FLORIDA—April 7, 2014—DNA Labs International today announced they are the first lab on the East Coast to offer an advanced forensic DNA collection service that helps investigators solve more crime. This new collection method, a wet-vacuum based sampling device called the M-Vac System, is more scalable and sensitive in collecting DNA material from evidence when compared to traditional sampling methods such as swabbing and cutting. This is critical in scenarios where the amount of DNA is minimal or the exact biological deposit location is unknown.
As far as crime laboratories go, it is not very impressive-looking. And it is not very big, with a permanent staff of just three forensic scientists and a few interns. But the work product that comes out of the Veterinarian Forensic Lab at UC Davis is important, and it has changed the way crimes are investigated and prosecuted worldwide.
