This Australian cave hid 25,000 years of ritual secrets
Microscopic plant remains are revealing how GunaiKurnai ancestors used Cloggs Cave for ritual practices over thousands of years. People deliberately gathered whole grasses, carried them into the dark cave, and burned them in thin layers, leaving behind traces that may span 25,000 years. A standing stone erected around 2,000 years ago and other ritual objects strengthen the evidence that the cave was a long-lived spiritual site.

Scientists discover a major brain shift between ages 50 and 75
Scientists have uncovered sweeping changes in how the human brain controls and organizes its genome beginning in midlife, offering new clues to why aging sharply increases the risk of Alzheimer’s and other neurodegenerative diseases. One of the biggest shifts occurred between about ages 50 and 75, when many of the brain’s original immune cells declined and were replaced by cells with more inflammatory characteristics. Researchers also found weakening of cells that help maintain the blood-brain barrier, along with widespread deterioration in the genome’s three-dimensional organization.
