🔴 **The Persistence of Tychonism**
“_In conclusion I will suggest that the historical longevity of
Tychonism has been considerably underestimated and also that Tychonists were not generally restrained from public endorsement of heliocentrism by religious pressure. On the contrary, I suggest that the continued acceptance of Tychonism was conditioned by its congruence with scientists’ religious beliefs._”

🔴 **Born On This Day**
Mathematician, astronomer, and physicist Pierre-Simon Laplace was born in Beaumont-en-Auge, Normandy, France on this day in 1749.
“_He proved the stability of the solar system. In analysis Laplace introduced the potential function and Laplace coefficients. He also put the theory of mathematical probability on a sound footing.”

🔴 🌍 **Global gridded population datasets systematically underrepresent rural population**
_“We find large discrepancies between the examined datasets, and, without exception, significant negative biases of −53%, −65%, −67%, −68%, and −84% for WorldPop, GWP, GRUMP, LandScan, and GHS-POP, respectively. This implies that rural population is, even in the most accurate dataset, underestimated by half compared to reported figures.”_

🔴 **A structured coalescent model reveals deep ancestral structure shared by all modern humans**
_“Using cobraa, we present evidence for an extended period of structure in the history of all modern humans, in which two ancestral populations that diverged ~1.5 million years ago came together in an admixture event ~300 thousand years ago, in a ratio of ~80:20%.”_

🔴 **Reviving the woolly mammoth isn’t just unethical. It’s impossible**
Adam Rutherford
_“You will never ever see a living woolly mammoth. While this is an obvious truth to most geneticists, zoologists and mammoth experts, the endless promises that you might get to meet an extant version of this very-much extinct elephantid apparently necessitate me typing it.”_
🔴 🧬 **A double-edged helix: The ethical consequences of widespread genetic screening**
_”Nevertheless, as genetic testing becomes more widespread, the storage of genetic data presents significant ethical and security challenges, prompting critical questions: Are current storage methods truly capable of safeguarding such sensitive information?”

🔴 **Inference of human pigmentation from ancient DNA by genotype likelihood**
_“We then applied that protocol to 348 ancient genomes from Eurasia, describing how skin, eye and hair color evolved over the past 45,000 years. The shift towards lighter pigmentations turned out to be all but linear in time and place, and slower than expected, with half of the individuals showing dark or intermediate skin colors well into the Copper and Iron ages.”_

🔴 🇬🇱 **Genetic architecture in Greenland is shaped by demography, structure and selection**
_“...we find twice as many high-impact genome-wide associations to metabolic traits in Greenland compared with Europe. We infer that the high-impact variants arose after the population split from Native Americans and thus are Arctic-specific, and show that some of them are common due to not only genetic drift but also selection.”_

🔴 ⚗ **S.P.L. Sørensen, the pH concept and its early history**
_“Introduced as a convenient symbol for ‘hydrogen ion exponent’ by the Danish biochemist S.P.L. Sørensen in 1909, after a decade or two pH won broad acceptance in the fields of physiology, biochemistry, medical research, and industrial chemistry in particular. Apart from detailing how pH and related concepts were initially received, this paper examines the language and nomenclature associated with the pH scale until about 1930.”_

🔴 **‘Female narcissism is often misdiagnosed’: how science is finding women can have a dark streak too**
Miriam Frankel
_"Researchers have discovered that narcissism can come in two types: grandiose and vulnerable. And Green has shown that while men are more likely to have grandiose narcissism, boasting high self-esteem and extroversion, women more commonly display the vulnerable form, involving introversion, defensiveness and low self-esteem. They may be more brittle and less boastful."_
