DNA from three ancient molars, one likely to be over a million years old, has revealed that there is a ghost lineage of mammoths that interbred with distant relatives to produce the North American mammoth population.

Dire wolves went extinct some 13,000 years ago, and for a long time researchers believed that Canis dirus (translation: “fearsome dog”) were a sister species to the gray wolf.What researchers found was that instead of just being some kind of beefed up gray wolf, dire wolves actually had very distinct DNA.
A few years later, he found himself working on the front lines of the young field’s marquee moon shot: the Human Genome Project.Eric Green: I was inside the Human Genome Project from day one, and I can’t stress enough how back then we didn’t know what we were doing.
Verogen, the foremost provider of next-generation DNA testing services for law enforcement, has spent the better part of this year developing a new test kit aimed at making genetic genealogy investigations both more convenient and more feasible to use for a wider range of crime scene samples.
The clinic, Idant, had opened three years earlier, one of the country’s first commercial sperm banks.
A close look at his DNA would expose just how unpredictable Crispr gene editing can be, and how much more scientists still need to learn before the technology can become routine practice for animal reproduction.
Tessera has spent the past two years developing a new class of molecular manipulators capable of doing lots of things Crispr can do—and some that it can’t, including precisely plugging in long stretches of DNA.It’s not gene editing, says von Maltzahn.
The BioSCAN project started when Brown bet a museum trustee that he could find a new species of insect in her backyard in West LA.In its first three years, Brown and the backyard collector discovered 30 new species of insects and published their results.
And now, they’re starting to dig somewhere else for clues: your DNA.On Monday, 23andMe launched a new study intended to illuminate any genetic differences that might help explain why people who’ve contracted Covid-19 have such varying responses to the infection.
No wonder it's hell marketing big solutions for the climate crisis to us; many of us think DNA in food is cause for alarm.A seminal book from the heyday of anthropology touches explicitly on meat, flesh, and irrationality: The Raw and the Cooked (1964).
Scientists at the Marine Biological Laboratory in Woods Hole, Massachusetts, and their colleagues reported on Monday in the journal Nucleic Acids Research that longfin inshore squid (Doryteuthis pealeii) are the first known animals that can edit messenger RNA outside the cell nucleus.
Stoeckle has been working with New Jersey state biologists to conduct DNA-based counts of commercial fish species by dropping one-liter bottles into the ocean at various depths and sampling the water inside.
To finally fit together these elusive sections of the genome, Somasekar Seshagiri, a geneticist and president of the SciGenom Research Foundation in Bangalore, and his collaborators used a combination of older sequencing methods with new ones that read out very long stretches of DNA .
The bunnies, and the digital files that described them, remained identical over many months.“This is a very initial foray into one of the more promising applications of DNA data storage: ubiquitous storage,” says Sriram Kosuri, a biochemist at UCLA who was not involved in the work.
One of the top geneticists in the country, Neale and his colleagues at the Broad Institute, a pioneering biotech hub in Boston, had a decade earlier developed software that made it much easier for scientists to study the vast amounts of genetic data that were beginning to flood in.
But if you want to replace a faulty gene with a healthy one, things get more complicated .In addition to programming a piece of guide RNA to tell Crispr where to cut, you have to provide a copy of the new DNA and then hope the cell’s repair machinery installs it correctly.
The genomic revolution has left Africa behind.“Currently, there’s this huge gap in genetic information,” says Abasi Ene-Obong, who studied cancer biology at the University of London before founding 54gene in January.
But soon after Darwin's death in 1882, the first wave of biologists to have grown up on his teachings took note of a curious occurrence in the realm of insects : During the second half of the 19th century, the predominant color of England's peppered moths had steadily shifted from mostly white to almost entirely black.
Apple's latest iPhone OS is here, you're being watched by your streaming devices, and you could soon get your DNA sequenced anonymously.The streaming apps are watching you: New research shows that over 2,000 of them are tracking information about your devices—even when you tell them not to .
Crispr Can Help Solve Our Looming Food Crisis—Here's How. The potential for gene editing to make every acre of land more productive in the face of climate change has captured the imagination of plant scientists, the agtech industry, and governments alike.
Eight months after a rogue Chinese scientist revealed he had secretly created the world’s first gene-edited children , the World Health Organization is asking countries to put a stop to any experiments that would lead to the births of more gene-edited humans.
And unlike the kinds of DNA technologies police have been using for decades to match crime scene samples to suspects, the genetic profiles generated for genealogy purposes hold a lot more information—including sensitive health information .Defense attorney Rachel Forde discusses evidence in the trial of William Talbott, who was found guilty Friday for the 1987 slayings of Jay Cook and Tanya Van Cuylenborg.
Deputy prosecutor Justin Harleman described the groundbreaking forensic technique to the jury Friday, including how a genetic profile of crime scene DNA was uploaded to a public genealogy database.
But new information in the stipulation agreement filed in court today reveals that the upload to GEDmatch occurred before the site changed its policy on May 20, 2018.According to the document, Detective Scharf asked Parabon to use genetic genealogy to help identify a possible source of the crime scene DNA on April 26, 2018, a day after authorities in California announced they’d used the technique in the arrest of the suspected Golden State Killer .
To crack a 32-year-old murder case, police used genetic genealogy, which involves searching family tree sites and the DNA that people add to them.
So two years ago, in a Hail Mary attempt to defend against potential bioengineered viruses, Evans and his research associate did something unthinkable: They revived an extinct cousin of smallpox called horsepox, using mail-order DNA.The Frankensteinian act stirred outrage among the international scientific community, which cast Evans as the Walter White of synthetic biology .
Megan Molteni covers biotechnology, medicine, and genetic privacy for WIRED.DHS officials say the pilot is just a small-scale evaluation to see if the technology can help root out cases of criminal fraud, including human trafficking and “child recycling.” Last month, former DHS Secretary Kirstjen Nielsen told a congressional committee that the agency had discovered multiple incidences of young people being passed around, or “recycled,” to help migrants gain illegal entry.
