DNA from ancient Egyptian mummies reveals their ancestry

Ancient Egyptians were an archaeologist’s dream. They left behind intricate coffins, massive pyramids and gorgeous hieroglyphs, the pictorial writing code cracked in 1799. Egyptians recorded tales of royalty and gods. They jotted down life’s miscellanies, too, as humdrum as beer recipes and doctor’s notes.
But there was one persistent hole in ancient Egyptian identity: their chromosomes. Cool, dry permafrost can preserve prehistoric DNA like a natural freezer, but Egypt is a gene incinerator. The region is hot. Within the mummies’ tombs, where scientists would hope to find genetic samples, humidity wrecked their DNA. What’s more, soda ash and other chemicals used by Egyptian embalmers damaged genetic material.

After 75 years, Utahn killed in Pearl Harbor comes home

The remains of U.S. Navy Musician 1st Class Elliott Deen Larsen, of Monroe, continue their journey home after arriving from Hawaii at the Salt Lake City International Airport in Salt Lake City on Thursday, May 25, 2017. Larsen died in the attack on Pearl Harbor in 1941, but it wasn’t until recently that his remains were identified through DNA testing.

Rugged innovation: Meeting the challenges of bringing high tech DNA analysis to the field

Expeditionlab’s GENE is a fusion of laboratory equipment and do-it-yourself (DIY) technological components adapted to conduct DNA extractions, amplifications, and sequencing outside of a standard laboratory setting.

Researchers traveled to the Kabobo Massif in the Democratic Republic of Congo to collect wildlife samples and test the process of species’ identification in the field using Gene.

The Expeditionlab team faced a host of challenges, including a shortage of electricity and hot, humid tropical weather, for which they successfully adapted the portable laboratory.

He died in the Pearl Harbor attack. He’ll be buried Saturday in his MN hometown

An Emmons, Minn., sailor killed during the attack on Pearl Harbor is finally on his way home.
Navy Fireman 3rd Class Glaydon I.C. Iverson, 24, died on Dec. 7, 1941, aboard the USS Oklahoma at Pearl Harbor. His remains had been unidentified and buried in a plot at the National Memorial Cemetery of the Pacific for more than 74 years.

APD Creates Team Dedicated to Clearing Rape Kit Backlog

AUSTIN, Texas — Austin’s interim police chief is adding more staff to the department’s sexual assault unit. Chief Brian Manley wants the DNA lab’s massive backlog to be a thing of the past.
At the backlog’s peak, Austin Police had more than 3,000 DNA kits waiting to be tested. They were from a variety of cases, but many stemmed from sexual assaults.

Ten years on, DNA on Coke can leads to arrest over $200,000 jewelry heist

A discarded can of Coca-Cola left behind from a low level break-in more than a decade ago helped Australian police catch the criminal behind a notorious robbery of more than $200,000 worth of jewelry from the shop in the city of Shepparton, in northern Victoria.

Garda told State lab lacks resources for full DNA analysis

The Garda have been told that full DNA tests of crime scenes will not be carried out in the case of “volume crimes”, such as burglary or car theft, due to limited resources.
Ireland’s first DNA database was established a year ago and has been widely praised for linking crimes to offenders on more than 600 occasions, including in 350 burglaries. The database now contains some 10,000 profiles from suspects, convicted criminals and sex offenders – a figure that is increasing by about 1,000 every month.

44 ‘hits’ found in DNA testing of old, backlogged Virginia rape evidence

DNA testing in 431 cases of collected but previously untested biological evidence recovered in Virginia rape cases has resulted in 44 DNA database “hits.”

7.2-million-year-old pre-human fossils challenge modern human evolution theory

A jawbone discovered by German troops in Athens during the Second World War could be evidence that apes and humans diverged 200,000 years earlier than the current theory says.
Chimpanzees and bonobos are the nearest known relatives to humans, sharing 99 per cent of our DNA. It’s believed that we split between five and seven million years ago.

ASCLD Webinar Series: DNA Standards and Guidelines

Hear from the Federal Bureau of Investigations on their efforts with the Scientific Working Group on DNA Analysis Methods to revise DNA standards and ensure quality operations as forensic analysis technology changes.

Boise State grant for post-conviction DNA testing comes with a catch

The Idaho Innocence Project will benefit from a $630,000 U.S. Department of Justice grant to test DNA in possible wrongful-conviction cases.
But none of the money can be used on Idaho cases, and the grant had to be given to Boise State University.

State forensic panel to fine tune familial DNA proposal

A special state subcommittee Friday will be fine tuning a proposal for New York State to use familial searching, an emerging DNA technique used to solve cold case homicides around the country.
The DNA subcommittee of the New York State Commission on Forensic Science will be voting on details of the plan to use familial searching, proposals that have been in the works since the beginning of the year. Under proposed guidelines, special DNA analysis will be allowed in cases of homicide, rape, arson and crimes involving “a significant public safety threat.”

The FBI has published its validation of STRmix™ for Use on Up to Five-Person Mixtures

The FBI has published its validation of STRmix™ for use on mixtures of up to five persons, as well as across a wide range of templates and mixture ratios.
The FBI began use of STRmix in casework in December 2015. This publication details the extensive validation work done by the FBI to underpin that casework use.

Priest’s DNA does not match profile from cold-case murder of nun

(CNN)A DNA sample taken from the exhumed remains of former priest A. Joseph Maskell does not match the DNA from the murder scene of Sister Catherine Ann Cesnik, according to Baltimore County Police.
Police announced on Wednesday that they had received results from Bode Cellmark Forensics laboratory in Lorton, Virginia, excluding Maskell as a contributor to a DNA profile developed from evidence taken in 1970 from the scene in Maryland where the decomposed body of Cesnik was found by a father and son out hunting. The 26-year-old nun had been missing for nearly two months.
