🧬⚰️ Researchers analyzed #DNA from 2,000-year-old remains found in hanging coffins on Chinese cliffsides, identifying them as ancestors of the modern Bo people. The study revealed genetic links spanning 4,500 years and connected the practice to ancient peoples across Southeast #Asia.

Jena Declaration (Genetics 🧬)
The Jena Declaration is a scientific statement that questions and refutes the concept of human "races in a biological sense". It was published in September 2019 at the 112th Annual Meeting of the German Zoological Society in Jena. The statement was written by leading scientists from the fields of evolutionary research, genetics and zoology, and wa...

Early-Onset Schizophrenia Study*
“For each GRIN2Anull-related mental disorder, we systematically compared cumulative disease incidence of GRIN2Anull carriers versus the average population using FinRegistry data as a nationwide control cohort, containing longitudinal electronic health records for the whole Finnish population (>5 million individuals, spanning 21 years of individual-level data).”
“Our findings establish GRIN2Anull as the first monogenetic predisposition to a broad spectrum of early-onset mental disorders, including early-onset schizophrenia.”
“We restricted the analysis to age bins in which the hazard is proportional as required by the Cox-PH model. GRIN2Anull carriers showed elevated lifetime incidence of psychotic disorders
(Hazard Ratio = 87,
95% Confidence Interval = [26.7-283.4],
p-value = 1.3e-13,
n = 4,
age bins = 0-12).”
“Strikingly, all four individuals in our cohort of GRIN2Anull-related mental disorders who received L-serine experienced phenotypic improvements, such as ceasing of hallucinations, remission of paranoid symptoms or improvement of behavioral disorder.”
*Note: This study is particularly interesting to me personally as a parent of a child, now an adult, who began experiencing hallucinations at four years of age. Look at that hazard ratio! Yes it is a tiny sample, but that is what one gets with early-onset psychosis which is extremely rare.

DNase I hypersensitive site (Genetics 🧬)
In genetics, DNase I hypersensitive sites are regions of chromatin that are sensitive to cleavage by the DNase I enzyme. In these specific regions of the genome, chromatin has lost its condensed structure, exposing the DNA and making it accessible. This raises the availability of DNA to degradation by enzymes, such as DNase I. These access...

🐱⚔️ A genetic analysis of 70 ancient cat genomes reveals domestic #cats arrived in #Europe only 2,000 years ago via Roman #military routes, not 6,000 years ago via Neolithic farmers as previously believed. Soldiers used cats for rodent control on military campaigns, with the #animals reaching #Britain by 100 CE and spreading throughout Europe along #Roman roads.

Are Northern Africans more closely related to Southern Europeans or to sub-Saharan Africans? I'd guess the former by a mile.
