Τρεις Έλληνες επιστήμονες βρήκαν αρχαίους ιούς στο ανθρώπινο DNA

Οι αρχαίοι ιοί μπορεί να κρύβονται στο DNA του ανθρώπου, καθώς οι επιστήμονες παρατήρησαν μια περίεργη πρωτεΐνη στις έγκυες γυναίκες, σύμφωνα με μια μελέτη του Σεπτεμβρίου 2017. Μια πρωτεΐνη που ονομάζεται HEMO έχει βρεθεί στα αγέννητα μωρά, αλλά το γονίδιο προέρχεται αρχικά από έναν ιό που μπορεί να έχει μολύνει τους προγόνους των θηλαστικών πριν από περισσότερα από 100 εκατομμύρια χρόνια, σύμφωνα με τη μελέτη “Ρόλοι ενδογενών ρετροϊών σε πρώιμα γεγονότα ζωής”, σύμφωνα με δημοσίευμα των New York Times.

Understanding 6th-century barbarian social organization and migration through paleogenomics

Applying a comprehensive analysis of genetic, historical, and archeological factors in two 6th-century barbarian cemeteries, researchers have gleaned new insights into a key era known as the Migration Period that laid the foundation for modern European society. Spanning the 4th to 8th centuries, this epoch followed the decline of the Western Roman Empire and was a time of major socioeconomic and cultural transformation in Europe. However, despite more than a century of scholarly work by historians and archaeologists, much about the period still remains unknown or is hotly debated, as reliable written accounts are lacking.

Father’s nicotine use can cause cognitive problems in children and grandchildren

A father’s exposure to nicotine may cause cognitive deficits in his children and even grandchildren, according to a study in mice publishing on October 16 in the open-access journal PLOS Biology by Pradeep Bhide of Florida State University in Tallahassee and colleagues. The effect, which was not caused by direct secondhand exposure, may be due to epigenetic changes in key genes in the father’s sperm.
