For the first time, scientists have shown that ancient human DNA can survive for thousands of years on cave walls, opening new ways to study prehistoric human activity. This interdisciplinary study was conducted within the framework of the First Art project, which is led by researchers from Spain and Portugal in collaboration with institutions across Spain, Portugal, the UK, China and Germany. The First Art project aims to date the earliest cave art and to characterise its chemical composition. In collaboration with researchers from the Max Planck Institute for Evolutionary Anthropology, the team has now extended their analyses to include DNA analysis.

Researchers studied the microbes associated with historical middens conserved in Greenland’s permafrost, left behind by Paleo-Inuit, ancient Norse, and early modern Inuit. These middens harbored biodiverse bacterial communities – including many unknown taxa – that were especially rich in human- and animal-associated groups. The authors concluded that microbial traces of human activities such as defecation, livestock farming, and seal hunting can linger for centuries in Arctic middens. They also found a wide range of antimicrobial resistance genes in the bacterial genomes. However, the limited outward spread of potential pathogens away from the frozen core of the middens means that they currently pose little risk to public health.  

A new study by Prof. Avraham Faust of Bar-Ilan University's Department of General History presents intriguing new evidence that may shed light on one of the most debated questions in the study of Israelite religion: did King Hezekiah's religious reforms actually occur, and did they transform religious practices throughout the Kingdom of Judah?

A new study has uncovered evidence that early human ancestors were using fire in South Africa's Wonderwerk Cave between 1.07 and 1.79 million years ago, extending the chronology of one of the earliest known records of fire use associated with hominins. By applying a new method that detects traces of burning in fossil bones, researchers found signs of repeated fire use deep inside the cave, far beyond the reach of natural wildfires. The findings suggest that early humans were bringing naturally occurring fire into the cave and maintaining it there, providing new insights into how our ancestors first began to harness one of the most important tools in human history.
