Research indicates that the Ames impact structure may have formed during the Late Devonian period. This finding challenges earlier beliefs connecting the structure to the Ordovician Meteor Event. Scientists utilized radioisotopic dating on zircon and plagioclase from impacted granite for their study. The zircon analysis revealed a maximum age of nearly 370 million years. These results may link the impact event to significant extinction events of that era.

Researchers re-examininf 46 skulls excavated from Egypt’s First Dynasty royal cemetery at Abydos, found significant cranial trauma in 18 of them. The injuries provide new forensic evidence that some people buried around royal tombs may have been deliberately killed after a ruler’s death. The findings support the possibility of retainer sacrifice, although the exact cause of death remains uncertain for many others.

A groundbreaking study by UCLA Health highlights the intriguing link between gut bacteria and brain ageing in healthy adults. Analyzing brain scans and gut health of nearly 1,500 participants, researchers identified a correlation between the Brain Ageing Index and certain gut microbes. This suggests that optimizing gut health may be pivotal for preserving cognitive function and offers an early detection path for interventions aimed at promoting healthier brain ageing.
