🔴 🇬🇱 **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."_

Athene Donald

_"One should remember back then papers were not online. Wading through the Science Citation Index – a very substantial collection of tomes which was the necessary route for me and generations before (and after) to try to track down who had cited which paper/ whose papers had been cited – was hard work in a library, not something one could skim through at one’s desk, and useless papers just take up unnecessary space."_

🔴 **Machine learning is bringing back an infamous pseudoscience used to fuel racism**

Mihai Andrei

_“The pseudoscientific framework of physiognomy laid a foundation for systemic racism, influencing fields like anthropology, criminology, and eugenics. These biases were embedded into societal structures and used to justify slavery, segregation, and colonialism. While physiognomy has been debunked as junk science, its legacy persists — and this is apparent in the new wave of AI physiognomy studies.”_

🔴 **North Pontic crossroads: Mobility in Ukraine from the Bronze Age to the early modern period**

_"We infer a high degree of temporal heterogeneity in ancestry, with fluctuating genetic affinities to different present-day Eurasian groups. We also infer high heterogeneity in ancestry within geographically, culturally, and socially defined groups. Despite this, we find that ancestry components which are widespread in Eastern and Central Europe have been present in the Ukraine region since the Bronze Age."_

🔴 **Ancient DNA reveals reproductive barrier despite shared Avar-period culture**

_“We reconstructed six-generation pedigrees at both sites including up to 450 closely related individuals, allowing per-generation demographic profiling of the communities. Despite different ancestry, these pedigrees together with large networks of distant relatedness show absence of consanguinity, patrilineal pattern with female exogamy, multiple reproductive partnerships (for example, levirate) and direct correlation of biological connectivity with archaeological markers of social status.”_

🔴 **Human migration from the Levant and Arabia into Yemen since Last Glacial Maximum**

_“Our results paint a picture of Yemen being in a crossroads, marked by the large-scale baseline genetic diversity that largely evolved many millennia. Yemen witnessed an initial gene flow pattern defined by the more ancient markers from the rest of the Arabian Peninsula and the Levant that started as early as the Epipaleolithic period followed by population isolation and limited expansion. Yemen witnessed additional, but less substantial, flow from southwest Asia, Jordan and Syria through the Nabateans during the active incense trade between the Levant and Yemen, from Arabia during the Islamic Expansion, and a subsequent one from the west and southwest dominated by East Africa.”_

🔴 **High-resolution genomic history of early medieval Europe**

_“We reveal evidence of the southward and/or eastward expansion of individuals who probably spoke Germanic languages and who had Scandinavian-related ancestry in the first half of the first millennium ce. We note that ‘Scandinavian-related’ in this context relates to the ancient genomes available, and so it is entirely possible that these processes were driven, for example, from regions in northern-central Europe. This could be consistent with the attraction of the greater wealth, which tended to build up among Rome’s immediate neighbours and may have played a major role in vectors of migration internal to communities in Europe who lived beyond the Roman frontier52.”_

🔴 **Trump and Musk are obsessed with genetics – but there’s no science behind their simplistic views**

Jonathan Roberts

_“The ubiquity of rhetoric that conflates DNA and identity risks propping up some insidious ideas. This is the language Musk and Trump thrive on, making exclusionary policies look like rational decisions grounded in science. Because, if genes are everything, why bother with policies aimed at tackling inequality? Why waste time and resources addressing social problems when we’re all just products of our genetic code?”_

_The team discovered it was the Zavaritskii volcano on the remote, uninhabited island of Simushir, which is part of the Kuril Islands – a disputed territory between Russia and Japan.”_

_“Using climate model simulations of idealized SG and data-driven of temperature-attributable mortality, we estimate that, in a world 2.5 °C warmer than preindustrial, 1 °C of global-average cooling by SG reduces mortality by over 400,000 deaths annually by 2080, with a possible range from −1.2 million to 2.7 million deaths annually.”_
