DNA tool allows you to trace your ancient ancestry

Scientists at the University of Sheffield studying ancient DNA have created a tool allowing them to more accurately identify ancient Eurasian populations, which can be used to test an individual’s similarity to ancient people who once roamed the earth.

Twins get some ‘mystifying’ results when they put 5 DNA ancestry kits to the test

Chief geneticist at a popular ancestry company admits it’s ‘kind of a science and an art’

DNA and the Globalization of Humanity

Two questions that have occupied the human mind since the beginning of civilization are “Who am I?” and “Where did I come from?” Today, with just a swab of saliva, millions of people worldwide have been able to take a peek into their genetic past, thanks to DNA testing. In most cases, such testing reveals a complex global and regional circulation of bloodlines.

A young woman whose body was found 31 years ago is ID’d in cold case as Anaheim resident

A young woman whose body was found in Anaheim 31 years ago was identified this week with the help of volunteers using the same technique that identified the suspected Golden State Killer.

New Solicitation: Research and Development in Forensic Science for Criminal Justice Purposes, Fiscal Year 2019

With this solicitation, NIJ seeks proposals for basic or applied research and development projects. An NIJ forensic science research and development grant supports a discrete, specified, circumscribed project that will:
1. Increase the body of knowledge to guide and inform forensic science policy and practice, or
2. Lead to the production of useful material(s), device(s), system(s), or method(s) that have the potential for forensic application.
The intent of this program is to direct the findings of basic scientific research; foster research and development in broader scientific fields applicable to forensic science; and support ongoing forensic science research toward the development of highly-discriminating, accurate, reliable, cost-effective, and rapid methods for the identification, analysis, and interpretation of physical evidence for criminal justice purposes.
All applications are due by 11:59 p.m. Eastern Time on April 11, 2019.

Mitochondrial DNA can be inherited from fathers, not just mothers

A tenet of elementary biology is that mitochondria — the cell’s powerhouses — and their DNA are inherited exclusively from mothers. A provocative study suggests that fathers also occasionally contribute.

The father of DNA says he still believes in a link between race, intelligence. His lab just stripped him of his titles.

Watson, who won the prize in 1962 for outlining the double-helix structure of DNA, wanted to offer penance for the comments that brought his reputation crashing down in 2007. That year, the scientist told Britain’s Sunday Times that he was “gloomy about the prospect of Africa” because he believed African intelligence was genetically lower than that of Europeans. Watson never lived the comments down, telling the Financial Times in 2014 that he believed the backlash had made him an “unperson.”

How DNA Test Results Can Change People’s Behavior And Physiology

“The answer isn’t really so simple. The answer is not, ‘Hey, don’t get genetic testing, it’s going to make you worse.’ It’s, ‘Hey, be mindful that receiving genetic risk puts you in a mindset,’ and that mindset can have an impact on your body as well as how you feel and how you behave.

DJ who murdered woman caught after crime scene DNA linked to ancestry database

DNA from the murder scene was kept in storage over the years and it was recently uploaded to a public genealogy database and compared against submitted samples.

Found in a cave in Northwest Alaska, an ancient tooth offers insights into the first inhabitants of the Americas

A paper published in 2018 analyzes the oldest ancient human remains found in the Arctic: a 9,000-year-old child’s tooth.
The tooth was discovered, and forgotten, way back in 1949 at Trail Creek Caves, right outside the community of Deering. Jeff Rasic, an archaeologist working with the National Park Service, told KNOM what makes its rediscovery so special.

Project will map genetic make-up of Armenian community

Members of the Armenian community have been asked to provide DNA samples on Sunday after a Christmas church service in Nicosia for research that aims to map the genetic background of the Cypriot population.
Armenians celebrate Christmas on January 6 and the Cyprus Institute of Neurology and Genetics (Cing) – which is carrying out the research – has chosen this date as the most suitable for the DNA collection since it the church was expected to see a bigger turnout than usual.
Members of the Armenian community over the age of 18 who were born in Cyprus and who would like to participate in the project, will give saliva samples after the liturgy.

Fingerprints to convicts: ACME tracks down the enemy

ACME is the only forensic operating lab in theater providing critical analysis to identify force protection threats and enable host nation criminal prosecutions.
The technicians and scientists within the lab specialize in capturing DNA, fingerprints and weapons technical inspection evidence to help defeat IED networks.

The 7 Most Fascinating Skeletons Of 2018

FORBES-This time last year, I highlighted the five most fascinating human skeletons that I felt succinctly summarized the year in bioarchaeological research. The bones that most intrigued me were the mortal remains of women and children, differently gendered people, and people with disabilities, or those who were least likely to make it into the history books. Although they couldn’t have imagined it at the time, these individuals taught archaeologists about what life was like hundreds or thousands of years ago.
2018 has continued this theme, producing bioarchaeological research that showcases both the interdisciplinary nature of this academic field but also the fact that even professionals can be surprised by what they find when they put their trowels in the ground. Here are the five individuals and two groups of people I found most fascinating this year:

All the reasons 2018 was a breakout year for DNA data

Genetic IQ tests. DNA detective work. Virtual drug trials. These were some of the surprising new uses of DNA information that emerged over the last 12 months as genetic studies became larger than ever before.

Scientists unravel the mystery of what regulates DNA replication

DNA replication was first described in the late 1950s, and scientists have been working ever since to explain just how this critical process is regulated. Researchers at Florida State University have finally solved the mystery.
