Giant elliptical galaxies are not as likely as previously thought to be cradles of technological civilizations such as our own, according to a recent paper by a University of Arkansas astrophysicist.

The paper, published May 1 in the journal Monthly Notices of the Royal Astronomical Society, contradicts a 2015 study that theorized giant elliptical galaxies would be 10,000 times more likely than spiral disk galaxies such as the Milky Way to harbor planets that could nurture advanced, technological civilizations.

The increased likelihood, the authors of the 2015 study argued, would be because giant elliptical galaxies hold many more stars and have low rates of potentially lethal supernovae.

Όταν το σύνθημα της επαναστάσεως εδόθη πλέον καθ’ όλην την Πελοπόννησον, οι κατά τας επαρχίας αυτής Έλληνες επεχείρησαν αμέσως την καταστροφήν των εις τας πόλεις εκάστης επαρχίας Οθωμανών. Το έργον τούτο δεν ήτο πολύ δύσκολον· διότι ο αριθμός των Ελλήνων ήτο πολύ ανώτερος του των Οθωμανών· εκ των τελευταίων δε τούτων οι μεν προκαταληφθέντες ανέτοιμοι προς αντίστασιν παρεδόθησαν αμέσως εις την διάκρισιν των Ελλήνων, ή κατεσφάγησαν καταπολεμηθέντες, οι δε απεκλείσθησαν εις τα οποία κατείχον φρούρια και δέφυγον προς ώραν την καταστροφήν, παρεδόθησαν όμως ακολούθως. Αλλά το κέντρον της κατά την Πελοπόννησον Οθωμανικής εξουσίας, η Τρίπολις, δεν παρείχεν ουδεμίαν ελπίδα ταχείας υποταγής.

Violent conflicts in Neolithic Europe were held more brutally than has been known so far. This emerges from a recent anthropological analysis of the roughly 7000-year-old mass grave of Schöneck-Kilianstädten by researcher of the Universities of Basel and Mainz. The findings, published in the journal PNAS, show that victims were murdered and deliberately mutilated.

Golden Horde warrior

An excellent reenactment of a warrior of the Golden Horde. Reenactor uknown, possibly from a Russian or a Kazakh reenactment group. Kudos to them.
The Golden Horde was one of the most important successor states of the Mongol Empire after its dissolution. The core area population was mostly of Turco-Mongol stock desceded mainly from the earlier Kipchak/ Cuman/Polovtsy tribal federation.
