Ancient DNA Links Europe’s Neolithic Collapse to Population Turnover and Migration

DNA from 132 individuals in a French tomb shows Europe’s Neolithic decline (~3000 BCE) involved a turnover in populations: pre- and post-collapse groups were genetically different, with two burial phases separated by centuries, signs of elevated mortality, and evidence of multiple pressures including disease; later migrations from southern France/Iberia reshaped the Paris Basin, indicating a multifactor disruption rather than a single cause.

Ancient Sheep Carries Clues to an Earlier, Livestock-Linked Plague

A 4,000-year-old sheep bone from Arkaim yielded DNA from Yersinia pestis, marking the first recovery of the plague genome from a non-human Bronze Age sample and suggesting livestock played a role in ancient transmission, indicating a dynamic between people, animals, and a still unidentified reservoir across Eurasia.

Scientists Uncover Origins of 1,500-Year-Old Pandemic

Scientists have confirmed that Yersinia pestis caused the Justinian Plague 1,500 years ago by analyzing genetic material from human remains in Jerash, Jordan, providing definitive biological evidence of the bacterium's role in one of history's earliest pandemics, and revealing patterns of recurrent plague outbreaks over millennia.

New Mexico Reports First Human Plague Case of 2025

A 43-year-old man in New Mexico has been diagnosed with plague, marking the state's first human case this year, likely contracted while camping. The disease, caused by Yersinia pestis, circulates in wildlife and can be transmitted through flea bites or contact with infected animals. Although treatable with antibiotics, early diagnosis is crucial, and health officials emphasize preventive measures such as avoiding sick rodents and using insect repellent. This case highlights the ongoing presence of plague in the western U.S., with recent cases also reported in California and Arizona.

California Reports New Bubonic Plague Case Amid Concerns

A rare case of the plague, caused by the bacterium Yersinia pestis, has reappeared in Northern California, likely contracted from a flea bite while camping. Despite being a disease of the past, it still exists in small numbers, primarily affecting rodents and occasionally humans, especially in rural and wilderness areas. There are no current FDA-approved vaccines, but the disease is treatable with antibiotics if caught early. Experts consider it under control and not a major public health threat today.
