One of these structures is the large cylindrical tomb of first-century noblewoman Caecilia Metella. New research shows that the quality of the concrete of her tomb may exceed that of her male contemporaries' monuments because of the volcanic aggregate the builders chose and […]

Located on high ground in the southern Jordan Valley, northeast of the Dead Sea, the settlement in its time had become the largest continuously occupied Bronze Age city in the southern Levant, having hosted early civilization for a few thousand years. At that time, it was 10 times larger than Jerusalem and 5 times larger than Jericho.

  • Early Homo sapiens groups in Europe faced subarctic climates
    on September 22, 2021 at 6:32 pm

    Using oxygen stable isotope analysis of tooth enamel from animals butchered by humans at the site of Bacho Kiro Cave, Bulgaria, researchers show that human groups belonging to an early wave of dispersal of our species into Europe were faced with very cold climatic conditions while they occupied the cave between about 46,000 and 43,000 years ago. Archaeological remains at Bacho Kiro Cave currently represent the oldest known remnants of Upper Palaeolithic Homo sapiens in Europe, and thus open a […]

  • Blowing up medieval gunpowder recipes
    on September 22, 2021 at 4:13 pm

    First used for battle in China in about 900 A.D., gunpowder spread throughout Eurasia by the end of the 13th century, eventually revolutionizing warfare as a propellant in firearms and artillery. Meanwhile, master gunners tinkered with gunpowder formulas, trying to find the ideal concoction. Now, researchers have recreated medieval gunpowder recipes and analyzed the energies released during combustion, revealing that the evolution of the perfect powder was a slow, trial-and-error process.
