"_A method normally used to create ice-skating rinks is now coming to the rescue of melting sea ice in the Arctic. Since satellite records began in 1979, summer Arctic sea ice has shrunk by around 13% per decade. Could making more ice be a potential solution to this issue?_"

🇳🇴 <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._"

Taking bacteria from substances such as wastewater, dental plaque or kimchi, Danino lets them multiply in a petri dish, adding dyes. The results are artworks differing from the digital enhancements often made in scientific photography to make images more informative._"

How to measure the Earth

"The first known calculation of the Earth’s circumference was made 2300 years ago by a man called Eratosthenes. I remember in school, how impressed I was by how accurately the Earth’s circumference was measured such long time ago. Today we’re going to take a closer look on how his calculation was made."

Thomas Willis (1621-1675) : Neurologist, Chemist, Physician

"Willis is not only credited to be the founder of neurology, but he is also seen as the father of comparative neuroanatomy, as his work, in particular Cerebri anatome and De anima brutorum, compare the human brain with that of other species in ‘search for specific human abilities in cognitive functions’ (Molnár, p. 334)."
