    Georgia State University scientists have created gene-edited hamsters for studies of social neuroscience and have found that the biology behind social behavior may be more complex than previously thought. A team of Georgia State University researchers led by Regents' Professor of Neuroscience H. Elliott Albers and Distinguished University Professor Kim Huhman used CRISPR-Cas9 technology to eliminate the actions of a neurochemical signaling pathway that plays a critical role in regulating social behaviors in mammals. Vasopressin and the receptor that it acts on called Avpr1a regulates social phenomena ranging from pair bonding, cooperation, and social communication to dominance and aggression. The...

    New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today "Originally, we all had brown eyes," said Professor Hans Eiberg from the Department of Cellular and Molecular Medicine. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a "switch," which literally "turned off" the ability to produce brown eyes." The OCA2 gene codes for the so-called P protein, which is...
  • Scientists Finally Sequence the Entire Human Genome While 92% of the human genome was sequenced in 2003, scientists have struggled to map the remaining 8%. Until now.

    When the Human Genome Project was declared completed in 2003, it had mapped 92% of genes, with the rest remaining a mystery for nearly two decades due to technological limitations. Now, scientists have finished sequencing the other 8%, and the human genome has finally been fully sequenced. Almost 100 scientists from the Telomere-to-Telomere (T2T) Consortium collaborated on the project to map the entire human genome. The additional 8% that was sequenced accounts for 400 million new letters added to the existing sequenced DNA -- enough for an entire chromosome, as CNN reported. The additional genes are very important for adaptation,...

    A bill addressing law enforcements use of genetic genealogy DNA databases like GEDmatch and Ancestry failed to pass the Utah House of Representatives late last week amid concerns it was not specific enough to prevent police “fishing expeditions.” The bill would have been the third in the nation to specifically address the use of third-party genetic genealogy databases in police investigations. House Bill 340 “Forensic DNA Privacy Amendments” was sponsored by Rep. Steve Eliason (R-Sandy), and was presented during a House Law Enforcement and Criminal Justice Committee in mid-February with the support of Greg Miller, CEO of the Larry H....
  • A Model of Catholic Bioethics: Venerable Jérôme Lejeune

    The National Catholic Bioethics Center ^ | 01.29.21 | Joseph Meaney, PhD, KM
    Jérôme Jean Louis Marie Lejeune (1926 – 1994)Bioethics is one of the few academic disciplines and professions that does not have a patron saint. We at The National Catholic Bioethics Center (NCBC) think this may change soon. Jérôme Lejeune, a French medical doctor and world class geneticist, was recently declared venerable — the first step on the road to canonization, by the Church. He led a remarkable life that began with scientific break-through discoveries and continued with decades of faithful work defending the right to life of human embryos and preborn children.It is remarkable to me that the Vatican declaration...
  • Up to 3% of Greenland residents - or 1,600 people - have rare genetic mutation that makes sugary food as healthy as broccoli for them, study finds

    Sugar may actually be healthy for some Greenland residents, a study finds. Researchers from the University of Copenhagen found that up to three percent of Greenlanders may have a rare genetic mutation that allows their body to process sugar in a way that is healthy. Since many people in Greenland come from gene pools that have consumed little sugar at all for centuries, their body has adjusted to consume sugar in a different way. Those who have the mutation are less likely to become obese, or suffer from a wide range of health problems generally tied to being overweight. 'Adult...

    (CNN)Since their discovery, the ancestry of hundreds of mummified bodies buried in boats in an inhospitable desert region of northwest China has puzzled and divided archaeologists.... Their Western looks; felted and woven wool clothing; and the cheese, wheat and millet found in their unusual graves suggested they were long-disticance herders.... However, a new study by Chinese, European and American researchers that analyzed the DNA of these 13 mummies, sequencing their genomes for the first time, has painted a different picture. Their analysis suggested that the remains did not belong to newcomers but a local group descended from an ancient ice...

    The National Counterintelligence and Security Center said American companies needed to better secure critical technologies as Beijing seeks to dominate the so-called bioeconomy. BETHESDA, Md. — Chinese firms are collecting genetic data from around the world, part of an effort by the Chinese government and companies to develop the world’s largest bio-database, American intelligence officials reported on Friday. The National Counterintelligence and Security Center said in a new paper that the United States needed to better secure critical technologies including artificial intelligence, quantum computing, semiconductors and other technologies related to the so-called bioeconomy. China and other countries are trying to...

    [H/T ExTexasRedhead and Jane Long]In January 2019, the WHO defined the growing number of vaccination critics as one of the top ten threats to global health, and since the unprecedented Corona vaccination fiasco, the number of vaccination refusers has truly multiplied.Meanwhile, resistance is forming even within the orthodox medical establishment. But the masterminds of the WHO continue to insist on an unrealistic vaccination coverage rate of at least 70 percent.In this article, Jan Walter describes, with extensive source citations, which techniques are possible to still vaccinate the population, when people are becoming increasingly critical of vaccinations. This is only fueled...

    A whole genome study discovered a number of genetic characteristics unique to those who live well past 100ljsphotography/Depositphotos VIEW 1 IMAGES In the most detailed genomic study ever conducted of individuals over the age of 100 years, researchers have homed in on several particular genetic characteristics that seem to confer protection from age-related diseases. Gene variants improving DNA repair processes were particularly prominent in this cohort of supercentenarians. If you eat well, exercise frequently and avoid those detrimental vices, you can reasonably hope to live a long and healthy life. Of course, many age-related diseases seem almost inevitable, whether they...

    The same science that explains why men and women respond differently to COVID vaccines also explains why eschewing sex in pursuit of gender fluidity is an exercise in futility.At any given time on The New York Times’ website, a quick search for “gender” will yield an array of articles on the ins and outs of sex personified and the endless ways biology teams up with political adversaries to oppress queer people.One recent so-called gender headline offered “A Guide To Neopronouns,” those nonsensical sounds like “ze” and “zir” that break from the sex binary and thus from reality. “Are you a...

    Rather than specifically triggering the toxic effects of organisms such as anthrax, the Sunshine project warned that weapons based on a new medical technique called RNA interference could shut down vital genes. If the sequence of the target gene varies between two different populations the technique could be used to interrupt key body functions in one population and not the other. "If as little as 10% or 20% of a target population would be affected, this would wreak havoc among enemy soldiers on a battlefield or in an enemy society as a whole," the group said. Others say the concerns...

    An article titled "m6A RNA modification as a new player in R-loop regulation," by the Dynamic Gene Regulation research group led by Arne Klungland at IMB, was published in the January edition of Nature Genetics. Following a new collaboration between UiO and research groups in Nottingham and Oxford, it has now been revealed that RNA has a direct effect on DNA stability, according to Professor Klungland's research. He believes the discovery will provide the health service with an important tool, since many studies have shown that the regulation of modifications to RNA is important for the development of cancer.

The document is critical, and the timing of its declassification was telling.As National Security Advisor Robert C. O’Brien noted in a statement announcing its release, the framework “has provided overarching strategic guidance for implementing the 2017 National Security Strategy within the world’s most populous and economically dynamic region.”By making the document...

    EXCLUSIVE – Joe Biden's pick to run the Justice Department's enormously powerful Civil Rights Division is a woman called Kristen Clarke. Clarke says her job is simple: End hate. But like so many in her world, Clarke is actually an enthusiastic purveyor of what she claims to fight. A new investigation by "Tucker Carlson Tonight" has uncovered shocking statements that Clarke made while attending Harvard as an undergraduate. In 1994, Clarke wrote a letter to The Harvard Crimson in her capacity as the president of the Black Students Association to explain her views on race science. "Please use the following...

    ....Researchers from the GenOMICC consortium compared the 2,700 ICU patients’ genetic information with samples from healthy volunteers from other studies. They discovered key differences in these five genes: IFNAR2, TYK2, OAS1, DPP9, and CCR. They “partially explain why some people become severely sick with Covid-19, while others are not affected.” “Our findings reveal that critical illness in Covid-19 is related to at least two biological mechanisms: innate antiviral defenses, which are known to be important early in disease (IFNAR2 and OAS genes), and host-driven inflammatory lung injury, which is a key mechanism of late, life-threatening COVID-19 (DPP9, TYK2, and CCR2),”...

    The economic situation in Africa has improved a lot since the 1990s.  Yet rampant poverty and food insecurity still impact millions of lives there. Currently, there is a huge demand-supply gap in the agricultural sector.  At least three hundred million are malnourished. The United Nations Food and Agricultural Organization defines food security as "a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life." Africa's agricultural sector needs to be strengthened to meet the demand for quality food.  In...

    Escaped self-cloning mutant crayfish created in experimental breeding programmes have invaded a Belgian cemetery. Hundreds of the duplicating crustaceans, which can dig down to up to a metre and are always female, pose a deadly threat to local biodiversity after colonising a historic Antwerp graveyard. "It's impossible to round up all of them. It's like trying to empty the ocean with a thimble," said Kevin Scheers, of the Flemish Institute for Nature and Woodland Research. Marbled crayfish, which travel across land and water at night and eat whatever they can, do not occur in nature and are banned by the...
