    The Japan Times, March 9, 1997Descendant of Stone Age skeleton found LONDON (Reuter) British scientists Saturday celebrated their feat of tracing a living descendant of a 9,000-year-old skeleton and establishing the world's oldest known family tree. In an astonishing piece of detective work, they matched mitochondrial DNA material extracted from the tooth cavity of Britain's oldest complete skeleton with that of a 42-year-old history teacher, Adrian Targett. The genetic material showed without doubt that Targett is a direct descendant through his mother's line of the skeleton known as Cheddar Man, which was found in 1903 in caves in Cheddar Gorge...

    The largest-ever study of ancient DNA from the Iberian Peninsula (Spain and Portugal) suggests that the Iberian male lineages were almost completely replaced between 4,500 and 4,000 years ago by newcomers originating on the Russian steppe... Most striking was an influx of new people during the later Copper Age, otherwise known as the Beaker period because of the ubiquitous presence in burials of large drinking vessels, from about 4,500 years ago. By the Early Bronze Age, 500 years later, these newcomers represented about 40% of Iberia's genetic pool - but virtually 100% of their male lineages... This is an extraordinary...

    When it comes to regeneration, some animals are capable of amazing feats. If you cut off a salamander’s leg, it will grow back. When threatened, some geckos drop their tails to distract their predator, only to regrow them later. Other animals take the process even further. Planarian worms, jellyfish, and sea anemones can actually regenerate their bodies after being cut in half. Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals pull off the feat, along the way uncovering a number of DNA switches that appear to...

    The FBI was allowed to comb through the information in a bid to identify crime suspects, igniting confidentiality concerns and privacy fears. Now, the gene-testing service has announced it will let customers bar law enforcement from accessing their data. Additionally, law enforcement agencies will need to go through a "separate process" when uploading their own files to the database in search of matches, and this can only be done in an effort to identify a deceased person or suspects involved in homicide or sexual assault. ...Giving customers the opportunity to opt out of giving the FBI access is an important...

    The DNA of life on Earth naturally stores its information in just four key chemicals—guanine, cytosine, adenine and thymine, commonly referred to as G, C, A and T, respectively. Now scientists have doubled this number of life’s building blocks, creating for the first time a synthetic, eight-letter genetic language that seems to store and transcribe information just like natural DNA. In a study published on 22 February in Science, a consortium of researchers led by Steven Benner, founder of the Foundation for Applied Molecular Evolution in Alachua, Florida, suggests that an expanded genetic alphabet could, in theory, also support life....

    The Austin Police Department could potentially reopen dozens of rape investigations after getting the results from its backlog of 2,665 untested rape kits. About 35 percent of the rape kits tested brought back positive DNA findings, which could mean as many as 933 cases. Austin Police outsourced the DNA testing of the untested rape kits to labs in other states to help tackle the backlog. All the testing was completed in April 2018 and now that investigators have the results, they are "reopening and beginning to work cases that correspond with kits that yielded positive results," according to a City...

    Worried about your privacy after taking an at-home DNA test? Here's what you should know and what you can do. If you’ve sent a DNA sample such as a tube of spit to 23andMe, Ancestry, MyHeritage, or one of the many other companies that offer direct-to-consumer genetic testing, you’ve sent them the essential information they need to provide you with their analysis of your genetic code. [SNIP] But if you later decide that you want to remove your genetic information from the web for privacy reasons, can you? And should you? Genetic data can reveal information about your health, your...

    Danielle Teuscher's 5-year-old daughter Zoe is one of thousands of children conceived with sperm from an anonymous donor. When Teuscher wanted to know more about her daughter's ancestry and possible health issues, she and other family members decided to get DNA tests from 23andMe and added one for Zoe. What turned up appeared to be one of the anonymous donor's immediate relatives. She was shocked. The donated sperm had come from Northwest Cryobank, which offers donors anonymity, but Teuscher said the apparent relative she found on 23andMe listed themselves as open to messaging. "I said 'I don't want to cross...

    CNN reports: "James Watson, who discovered the double-helix structure of DNA alongside Francis Crick in the 1950s based on the work of British chemist Rosalind Franklin, said in a PBS film that genes cause a difference in intelligence between white and black people in IQ tests. "The 90-year-old's comments were labeled 'reprehensible' by the Cold Spring Harbor Laboratory (CSHL) on New York's Long Island, where Watson had been the director from 1968 to 1993. The laboratory said it 'unequivocally rejects the unsubstantiated and reckless personal opinions Dr. James D. Watson expressed,' noting the statements were 'reprehensible [and] unsupported by science[.]'"...

    A Pennsylvania wedding DJ admitted Tuesday to raping and strangling to death an elementary school teacher whose 26-year cold case was solved with help from DNA submitted to a genealogy database by his half-sister. In court Tuesday, Raymond Rowe, 50, pleaded guilty to first-degree murder in the death of 25-year-old Christy Mirack, online court records show. Rowe went by the stage name DJ Freez and claimed on his now-defunct website he worked as a DJ for celebrities such as Paris Hilton and Brooke Hogan, as well as at events featuring Sting, The Eagles and Kenny Kravitz. He was sentenced to life in prison without...

    ... Christy Mirack was found on the floor of her living room on December 21, 1992, strangled, beaten with a wooden cutting board and raped. DNA was collected at the scene, but there were no matches -- until last year, when the sample was sent to Parabon NanoLabs, a DNA technology company, for genetic testing. Parabon NanoLabs generated a genotype file from the DNA sample, then a DNA phenotype "composite" of the killer's attributes -- including hair, eye color and skin tone, the district attorney said. That helped experts get an idea of what the killer looked like as he...

Tribal citizenship is very different from ancestry. Tribes and only tribes determine tribal citizenship and I respect that difference,” she continued.

    The newly-elected Robeson County Sheriff is revealing new details about a missed warning that could have kept an accused murderer behind bars. In an exclusive interview with the ABC11 I-Team, Sheriff Burnis Wilkins confirms at least two members of the sheriff's office knew about DNA evidence linking Michael McClellan to an old rape case more than a year before McClellan allegedly kidnapped and murdered Hania Aguilar. District Attorney Johnson Britt told ABC11 at the time that McLellan's DNA from that case was used in the investigation of Hania's case. Britt, however, would later reveal that the Robeson County Sheriff's Office...

    Chewed tar is an unexpectedly great source of ancient DNA. No one today quite understands how they did it, but people in the Stone Age could turn ribbons of birch bark into sticky, black tar. They used this tar to make tools, fixing arrowheads onto arrows and blades onto axes. And they chewed it, as evidenced by teeth marks in some lumps. These unassuming lumps of chewed birch-bark tar turn out to be an extraordinary source of ancient DNA. This month, two separate research groups posted preprints describing DNA from the tar in Stone Age Scandinavia. The two papers have...
