<strong>Five of the best books about maths</strong>
"_Since the Egyptian scribe Ahmes put pen to papyrus some time around 1550BC to explain how to calculate the slope of a pyramid, we’ve had over three millennia of maths literature. So within some level of statistical confidence: here are a subset of the best ever maths books._"

<strong>Late Neolithic collective burial reveals admixture dynamics during the third millennium BCE and the shaping of the European genome</strong>
"_To conclude, our study of a Late Neolithic burial enables direct, quasi–real-time observation of the trimodal admixture processes in Europe between 3300 and 2600 cal BCE as steppe ancestry people dispersed and mixed with local Neo-ancestry groups or individuals. The generalization of the results obtained from our data suggests that this genomic transformation took place during a period of profound cultural change._"

<strong>The big idea: can you inherit memories from your ancestors?</strong>
"Scientists working in the emerging field of epigenetics have discovered the mechanism that allows lived experience and acquired knowledge to be passed on within one generation, by altering the shape of a particular gene. This means that an individual’s life experience doesn’t die with them but endures in genetic form."

<strong>The Enduring Mystery of How Water Freezes</strong>

<strong>The potential of lacustrine sedimentary ancient DNA for revealing human postglacial recolonization patterns in northern Sweden – a review</strong>
"_The questions of who the first postglacial peoples, or pioneers, were and where they came from therefore remain unanswered. Previous palaeogenomic analyses from remains from adjacent regions have suggested that two main routes into Sweden could have been taken by the pioneers, one from the SW through modern-day Denmark and Norway, and one from the east via Finland. However, no direct genetic evidence from the pioneers of northern Sweden exists._"

<strong>Did the Condemnation of 1277 Create Modern Science?</strong>
"_The purpose of the Condemnation of 1277 was to stomp out any thought not strictly in accord with Church doctrine, including its various miracles such as the transformation in the Eucharist. To the extent that this condemnation was actually followed, it would have led to complete intellectual stagnation._"

🇳🇴 <strong>Norwegian farmer finds 1,000-year-old Viking sword on family farm</strong>
"_X-ray scans of the sword revealed outlines of rare inscriptions with a cross pattern and the likely presence of letters on the blade._
_Based on these inscriptions, scientists said it could be a so-called Vlfberht sword, produced during the Viking Age or the early Middle Ages between 900 and 1050AD._"

<strong>The Ancestors of Today's Poles with the Haplogroup R1a</strong>
"_Genetic studies proved the autochthonic theory of Polish origin to be true at least as by the 2nd century BCE or possibly about 2000 BCE. The Polish nobility’s myth was its Sarmatian origin, a myth that proved to be true partially culturally and partially genetically. The Scythian and Slavic peoples grow out of the same Indo-European genetic trunk, or
rather, they are branches of the same thicker limb._"

<strong>Evidence for dynastic succession among early Celtic elites in Central Europe</strong>
"_The historical and archaeological record leave no doubt that the development of culture and population in southwestern Germany was temporarily characterized by profound discontinuities, particularly during the third to first century BCE. The definitive end of the 2,000 years of relative genetic continuity from the Bronze throughout the Iron Age in southern Germany is marked by a sudden, sharp increase of Steppe-related ancestry during the Late Antiquity and Early Middle Ages._"

<strong>Mathematicians Attempt to Glimpse Past the Big Bang</strong>
"_Researchers already knew that in a universe with so-called dark energy, but without matter, the start of inflation identified in the BGV theorem is a coordinate singularity that can be eliminated. But the real universe has matter, of course. Might mathematical tricks also make it possible to get around its singularity? The researchers showed that if the amount of matter is negligible compared to the amount of dark energy, then the singularity can be eliminated._"
