New study: Surprising diversity of ethnic groups in the US Virgin Islands before Columbus
When Christopher Columbus arrived at the present-day US Virgin Islands on his second voyage across the Atlantic in 1493, the islands were already inhabited – but how and when the islands of St. Croix, St. John, and St. Thomas were originally populated remains uncertain.
Want Better Kimchi? Make It Like the Ancients Did
In a combined experimental and theoretical study, Georgia Tech researchers measured carbon dioxide levels in onggi during kimchi fermentation and developed a mathematical model to show how the gas was generated and moved through the onggi’s porous walls. By bringing the study of fluid mechanics to bear on an ancient technology, their research highlights the work of artisans and provides the missing link for how the traditional earthenware allows for high quality kimchi.
Lasers and chemistry reveal how ancient pottery was made — and how an empire functioned
Peru’s first great empire, the Wari, stretched for more than a thousand miles over the Andes Mountains and along the coast from 600-1000 CE.
The colors on these ancient pots hint at the power of an empire
In a new study, archaeologists compared the colors on pieces of ancient Peruvian pottery. They found that potters across the Wari empire all used the same rich black pigment to make ceramics used in rituals: a sign of the empire’s influence.
