A team of researchers from France, Sweden, and Denmark have identified a new strain of Yersinia pestis, the bacteria that causes plague, in DNA extracted from 5,000-year-old human remains. Their analyses, publishing Dec. 6 in the journal Cell, suggest that this strain is the closest ever identified to the genetic origin of plague. Their work also suggests that plague may have been spread among Neolithic European settlements by traders, contributing to their decline.
More than two centuries before initiatives to increase the number of women in STEM fields, Maria Sibylla Merian was a professional artist and naturalist whose close observations and illustrations were the first to accurately portray the metamorphosis of butterflies and moths and emphasize the intimate relationship between insects and their host plants. Now, a new Central American butterfly species has been named in her honor.
In a new study, Robert Schwaller, KU associate professor history, argues that Spanish colonial records reveal that resistance by indigenous and African maroons, who were runaway slaves, not only tested Spanish economic and labor arrangements but also challenged European conquest itself.
Linguistic study finds 'the I's have it' when it comes to education rates.
Argentine and Spanish researchers have used statistical techniques of automatic learning to analyze mobility patterns and technology of the hunter-gatherer groups that inhabited the Southern Cone of America, from the time they arrived about 12,000 years ago until the end of the 19th century. Big data from archaeological sites located in the extreme south of Patagonia have been used for this study.
As far back as 40,000 years ago, humans kept track of time using relatively sophisticated knowledge of the stars
Researchers from Wits and colleagues from the University of Antananarivo in Madagascar are on a 'detective mission' to describe, classify and trace the history of a meteorite that landed in and around the small town of Benenitra in southwestern Madagascar shortly before the lunar eclipse on July 27, 2018.
New research led by the Threatened Species Recovery Hub has revealed which Australian mammals are most vulnerable to cats and foxes, and many much-loved potoroos, bandicoots and bettongs, as well as native rodents, are at the top of the list.
University of Cincinnati geography professor Tomasz Stepinski created a new world map showing dramatic changes in land use over the last quarter century. Stepinski turned high-resolution satellite images from the European Space Agency into one of the most detailed looks so far at how people are reshaping the planet.
A study by an international team of researchers, including from the University of Washington, determines that carved stone tools, also known as Levallois cores, were used in Asia 80,000 to 170,000 years ago. With the find -- and absent human fossils linking the tools to migrating populations -- researchers believe people in Asia developed the technology independently, evidence of similar sets of skills evolving throughout different parts of the ancient world.
