Grain… Seed… Born!
Researchers examined stable isotopes from bone collagen and dental enamel to reconstruct the diets of ancient Mongolians. Findings challenge the popular notion of a completely nomadic prehistoric population, linking grain cultivation with the success of the Xiongnu Empire (c. 200 BCE-150 CE) and showing continual grain consumption during the Mongol Empire of the Khans (c.

In a recently released edition of the Journal of Field Archaeology, Brown Assistant Professor of Anthropology Parker VanValkenburgh and several colleagues detailed new research they conducted in the former Inca Empire in South America using drones, satellite imagery and proprietary online databases. Their results demonstrate that big data can provide archaeologists with a sweeping, big-picture […]

Rough.
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that […]

Ancestral asymmetries…
The left and right side of the brain are involved in different tasks. This functional lateralization and associated brain asymmetry are well documented in humans, but little is known about brain asymmetry in our closest living relatives, the great apes. Using endocasts (imprints of the brain on cranial bones), scientists now challenge the long-held notion […]

Old mummy… Silent voices…
The sound of a vocal tract from a 3,000-year-old mummy has been recreated using CT scans, a 3D-printer, and a voice synthesizer. Details of this achievement—such as it is—were published in Scientific Reports. (1) Old voices. Lost voices. Meaning nothing now. Frightening isn’t it? Why don’t we understand those voices? Why do we need to? […]
