    Genealogy websites have become increasingly popular in recent years. These platforms are able to scour the web in search of documents and archival data, which can help users build historically accurate family trees. There’s also another side to genealogy websites that has attracted attention from privacy advocates: DNA testing. Websites like Ancestry.com can use DNA testing to find matches, but the fact that these platforms store this information on their end means that hackers could try and steal it. Tap or click here to see how Ancestry.com suffered a huge data breach. Since genealogy websites collect so much data, their...

    [Ghost] DNA from an unknown ancient ancestor of humans that once bred with Denisovans still exists among the genomes of people today, a study has revealed. The different branches of the human family tree have interbred and swapped genes -- a processes known as 'introgression' -- on numerous occasions... Experts from the US found that some three per cent of the Neanderthal genome came from interbreeding with another ancient human group 300,000 years ago... The researchers used the algorithm to look at genomes from two Neanderthals, a Denisovan and two African humans. Alongside finding that a small proportion of the...

    Authorities did not provide details on Neal’s illness, but said he was not exhibiting COVID-19 symptoms. Before his hospitalization, he was being held at the Theo Lacey maximum-security jail in Orange. In February 2019, Neal was identified as a suspect in the sex assault and killing of 11-year-old Linda Ann O’Keefe, a case that had stymied investigators for more than four decades. O’Keefe was abducted while walking home from school in the summer of 1973. Her strangled body was later found dumped in a ditch in Newport Beach’s Back Bay. DNA evidence collected at the crime scene eventually linked Neal...

    Study Finds ^ | July 19, 2020 | by John Anderer
    SAN DIEGO — The average American lives to be around 75 or 80 years old; but if you had an opportunity to slow down the aging process and live an extra couple of decades would you take it? It’s a loaded question, strife with philosophical, religious, and societal considerations. Humans have pondered the possibilities of extended, or even immortal, life for as long as we’ve inhabited this planet. But at the end of the day it’s all just a daydream, right? Not necessarily, according to new research out of the University of California, San Diego. The study, led by UCSD...

    The police in China are collecting blood samples from men and boys from across the country to build a genetic map of its roughly 700 million males, giving the authorities a powerful new tool for their emerging high-tech surveillance state. They have swept across the country since late 2017 to collect enough samples to build a vast DNA database, according to a new study published on Wednesday by the Australian Strategic Policy Institute, a research organization, based on documents also reviewed by The New York Times. With this database, the authorities would be able to track down a man’s male...

    One of my sisters had put DNA in to 23 & Me sometime in the past (several years ago, maybe). Over the past week, she has been notified of a person who just recently submitted DNA for testing. It turns out that this person seems to be our half-sibling. There are 5 of us from same parents, all born from 1954 to 1960. The newly identified one seems to be related only to our father and born in 1964. I babysat for this person and two siblings, when I was around 10 or 11. Their family moved away around 1969,...

    One in three women in Europe inherited the receptor for progesterone from Neandertals -- a gene variant associated with increased fertility, fewer bleedings during early pregnancy and fewer miscarriages. This is according to a study published in Molecular Biology and Evolution by researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden... Progesterone is a hormone that plays an important role in the menstrual cycle and in pregnancy. Analyses of biobank data from more than 450,000 participants -- among them 244,000 women -- show that almost one in three women in Europe have inherited...

    Variant Bio has spent the last several years scouring the world for genetic outliers in human beings. It found a small group of “outlier humans” with special variations in their DNA that could affect disease risk and eventually be used to develop medicines to improve human life. Founded in New York, the 10-person startup’s lead geneticist Stephane Castel is focusing on the DNA of Sherpa people living at high altitudes in Nepal and Himalayas. Their unique genetic characteristics allow them to live healthy lives with blood oxygen levels far below what most humans need. Most people in high altitudes suffer...

    The researchers used advanced ancient DNA capture techniques to retrieve ancient DNA from 25 individuals dating back 9,500-4,200 years and one individual dating back 300 years from northern and southern East Asia... Prof. FU and her team found that these Neolithic humans share the closest genetic relationship to present-day East Asians who belong to this "second layer." This suggests that by 9,500 years ago, the primary ancestries composing the genetic makeup of East Asians today could already be found in mainland East Asia. While more divergent ancestries can be found in Southeast Asia and the Japanese archipelago, in the Chinese...

    Genetic enhancement may not be restricted to the pages of sci-fi novels for much longer. For example, scientists have already inserted genes from tardigrades — tiny, adorable and famously tough animals that can survive the vacuum of space — into human cells in the laboratory. The engineered cells exhibited a greater resistance to radiation than their normal counterparts... Tardigrades and "extremophile" microbes, such as the radiation-resistant bacterium Deinococcus radiodurans, "are a great, basically natural reservoir of amazing traits and talents in biology," added Mason... "Maybe we use some of them." Harnessing these traits might also someday allow astronauts to journey...
  • Ancient Andean Genes Reveal DNA Continuity Amid Cultural Clashes

    Led by researchers at Harvard Medical School and the University of California, Santa Cruz, the team analyzed genome-wide data from 89 individuals who lived between 500 and 9,000 years ago. Of these, 64 genomes, ranging from 500 to 4,500 years old, were newly sequenced - more than doubling the number of ancient individuals with genome-wide data from South America. The analysis included representatives of iconic Andean civilizations from whom no genome-wide data had been reported before, including the Moche, Nasca, Wari, Tiwanaku and Inca. The central Andes, surrounding present-day Peru, is one of the few places in the world where...

    When all babies’ DNA is stored forever and accessible to whoever has the most money or political clout, no one’s most fundamental privacy is secure. The coronavirus pandemic has intensified the discussion about the right to biological privacy. Dr. Anthony Fauci at White House press conferences muses about “certificates of immunity” to be carried by Americans who have antibodies to the virus. Bill Gates advocates a national tracking system so the government can see where the virus is. Whether his envisioned system involves microchipping the population is the subject of some debate. Privacy advocates warn about allowing the government to...

    The Trump administration plans to begin taking DNA samples from migrants crossing the border or held in detention for use in a federal criminal database, a significant expansion of immigration laws that is certain to raise privacy concerns. The new rule, posted by the Justice Department on Friday and set to take effect in April, will require immigration officers to collect cheek swabs from what could amount to hundreds of thousands of unauthorized immigrants taken into federal custody each year, including migrants at the border and people asking for asylum. The move, which is sure to face court challenges, injects...

    Gene drives use genetic engineering to create a desired mutation in a few individuals that then spreads via mating throughout a population in fewer than 10 generations. In theory, such a mechanism could be used to prevent malarial mosquitoes from transmitting disease, or possibly to wipe out an invasive species by disabling its ability to reproduce. Though scientists have had success proving the concept in the lab, they have found that wild populations invariably adapt and develop resistance to the scheme. And when gene drives work, they are all or nothing—without nuance—they spread to all individuals, which can be a...

    Palaeontologists have announced the discovery of organic material in 75-million year old dinosaur fossils. The team claims to have found evidence of cartilage cells, proteins, chromosomes and even DNA preserved inside the fossils, suggesting these can survive for far longer than we thought. The researchers, from the Chinese Academy of Sciences and North Carolina State University, made the discovery in skull fragments of Hypacrosaurus, a duck-billed herbivore from the Cretaceous period. These particular specimens were “nestlings”, meaning that at time of death they weren’t yet old enough to leave the nest. Inside the skull fragments, the team spotted evidence of...

Could this be the last straw? For two decades now, especially since 2005, creationists have been challenging deep-timers (those who believe life is hundreds of millions of years old, and earth is 4.5 billion years old) with dinosaur soft tissue. Secular reports have been coming in regularly about soft tissue in fossils: feathers, melanosomes, collagen, various proteins, and materials in dinosaur bones that look like stretchy blood vessels and...
