Analysis of Bronze Age Teeth Shows How Dietary Change Drove the Evolution of Caries Bacteria

New research has shed light on the evolution of oral health and the impact of dietary changes on the human mouth. A team of scientists has successfully extracted and analyzed microbial DNA from two remarkably well-preserved 4,000-year-old teeth discovered in a limestone cave in Ireland. Their findings, which include the identification of gum disease-causing bacteria […]

Analysis Reveals Three Cases of Down Syndrome in Iron Age Spain, More than 2,500 Years Ago

An international investigation that has analyzed the genome of nearly 10,000 ancient individuals in search of chromosomal trisomies has identified six cases of Down syndrome, all of them in babies: five from between 5,000 and 2,500 years ago and one from a more recent period. Three of the prehistoric cases come from sites of the […]

Analysis Reveals the Fall of the Roman Empire Prevented the Disappearance of Regional Genetic Differences

For over 1,000 years, the Roman Empire connected diverse populations in new ways through trade routes, economic and political cooperation, and joint military endeavors. Now, an international team led by researchers at Stanford Medicine has used ancient skeletal DNA to paint a detailed picture of travel and migration patterns during the empire’s peak. Their study, […]

Researchers Demonstrate that Human Cells “Vibrate”

A research team from the CSIC (Spanish National Research Council) has achieved a significant breakthrough in understanding the mechanical properties of human cells: it has successfully demonstrated that living cells, specifically human breast epithelial cells, exhibit mechanical resonances, a phenomenon previously considered unlikely due to the extraordinary viscosity and complexity of cells in physiological environments.

Denisovan Genetic Heritage Could Affect Mental Health of European and Asian Populations

A new study conducted by researchers from the Institute of Evolutionary Biology (IBE) in Spain has revealed that modern humans outside of Africa inherited a genetic variant from the Denisovans, an extinct species related to Neanderthals, which may have helped them adapt to the cold during the expansion out of Africa around 60,000 years ago.
