California Attorney General Xavier Becerra [yesterday] announced a DNA technology advancement that will enable the California Department of Justice…to increase its ability to successfully identify unknown persons. The Department is the first accredited state crime lab in North America to begin fully sequencing mitochondrial DNA, which makes it easier to test degraded evidence samples that have been subjected to harsh environmental conditions. This advancement is particularly important for being able to process DNA involving unknown human remains and help families find closure regarding loved ones who have gone missing.

California Becomes First State Accredited For New Technology Which Will Make It Easier To Test DNA Exposed To Harsh Conditions
In late June 1994, a helicopter banked over the Charley River in Alaska’s eastern Yukon wilderness. Below, on a hillside of granite and greenstone, was the wreckage of a B-24D bomber that went down Dec. 21, 1943 during a flight to test the plane’s systems in extreme cold.
Doug Beckstead, a National Park Service historian, pressed his face against the glass for his first view of the “Iceberg Inez,” one of the many hulks of lost aircraft across Alaska.
This one came with a remarkable backstory. The lone survivor — co-pilot 1st Lt. Leon Crane, a city kid from Philadelphia — made his way out of the frozen Yukon wilds after an 81-day ordeal.
Florida investigators on Thursday released DNA evidence that they say helped lead to the arrest of a woman suspected of dressing up as a clown and fatally shooting her future husband’s then-wife 27 years ago.
Palm Beach County prosecutors said that recent forensic tests conducted by the FBI concluded that hair fibers found in a suspected getaway car could have come from Sheila Keen Warren.
…The painstaking case of lost and found for the Van Bendegom family is only one of many that is playing out around the world. There may eventually be thousands more. Over fifteen hundred Americans who fought and died in the Vietnam War have yet to be identified; and that is only one war. Government officials estimate there are another 7800+ unidentified lost in the Korean War, and 125+ missing soldiers who fought and died in the Cold War. More than 73,000 service personnel from World War II still remain unidentified today…
SEOUL, South Korea — Amid a backlog of requests from aging war survivors, the Korean Red Cross is dramatically expanding its collection of genetic material from South Koreans separated from their families during the Korean War.
UNIVERSITY PARK, Pa. — A new grant from the National Institute of Justice (NIJ) will help scientists from Penn State’s Eberly College of Science delve deep into the world of mitochondrial DNA, or mtDNA, used to help solve crime in forensic investigations.
The Bode Technology Group, Inc.(Bode), a leading provider of forensic DNA services and products, in collaboration with the University of Wisconsin (UW), announced the successful DNA testing of 70-year old bone fragments from a missing World War II soldier.
Japanese authorities who are still trying to identify the remains of victims of the 2011 Great East Japan Earthquake and tsunami say they are having greater success testing mitochondrial DNA (mtDNA) compared to conventional testing methods.
The skeletal remains of two infants found in North Canton will be sent to the University of North Texas for testing Tuesday. Police and investigators hope result will answer questions surrounding the bones, which were found in a deceased woman’s home more than a month ago.
Last July, researchers reported that they had found a direct genetic link between the remains of Native Americans who lived thousands of years ago and their living descendants. Scientists used mitochondrial DNA to track three maternal lineages from ancient times to the present, comparing the complete mitochondrial genomes of four ancient and three living individuals from the north coast of British Columbia, Canada.
The findings not only will cause population experts to rethink ancient migrations into this area, but according to advocates for native populations, will solidify these groups’ claim to their ancestral homelands.
Neolithic hunter-gatherers and farmers lived side by side without having sex for more than 2,000 years, new research suggests.
Analysis of fossil skeletons unearthed in a cave in Germany revealed that the two populations remained mostly separate for two millennia, despite living in the same region.
A new genetics study has challenged previous theories about the maternal ancestry of Ashkenazi Jews.
The study suggests that most female ancestors came from southern and western Europe, not the Middle East as some authors assume.
