In the early 19th century in North America, parasitic infections were quite common in urban areas due in part to population growth and urbanization. Prior research has found that poor sanitation, unsanitary privy (outhouse) conditions, and increased contact with domestic animals, contributed to the prevalence of parasitic disease in urban areas. A new study examining fecal samples from a privy on Dartmouth's campus illustrates how rural wealthy elites in New England also had intestinal parasitic infections.
A new study from the University of Kansas just published in the open-access journal Comptes Rendus Geoscience, may answer "one of the greatest mysteries of our time . . . when humans made the first bold journey to the Americas."
CT scanning used to uncover remnants of malignancy hidden inside medieval bones provides new insight into cancer prevalence in a pre-industrial world.
In the medium and long-term periods, climate shocks favoured cooperation among diverse groups of people. Indeed, by enlarging access to political and property rights, elites who had decision-making powers could work with other groups who held the skills and tools to overcome those crises
A team of scientists has found that women's football was common across Japan between the Meiji restoration and the start of the Second World War. In the process, they also uncovered the oldest known photograph of women playing football in Japan, from 1916.
A new study by five doctoral students in neuroscience at the University of Minnesota Medical School calls attention to a lack of regulation and unknown long-term health effects of tear gas. Based on their research, the group recommends changing the protocols around the use of tear gas as a crowd control measure at both the local and national level.
The Chauvet Cave, which lies by the entrance to the Gorges of the Ardèche, is home to the world's oldest cave paintings, dating back 36,000 years. The location of the cavern--surrounded by a remarkable landscape, next to the Pont d'Arc natural archway--raises the question of whether the people who executed these artworks looked and walked out upon the same landscape as today. Did they see the same natural archway?
A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests--cared for as "forest gardens"--contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators.
The Dead Sea Scrolls, discovered some seventy years ago, are famous for containing the oldest manuscripts of the Hebrew Bible (Old Testament) and many hitherto unknown ancient Jewish texts. But the individual people behind the scrolls have eluded scientists, because the scribes are anonymous. Now, by combining the sciences and the humanities, University of Groningen researchers have cracked the code, which enables them to discover the scribes behind the scrolls.
The evolution of metalwork expertise and craftsmanship developed by Viking craftspeople in Denmark in the 8th and 9th centuries has been detailed in a study published in Archaeological and Anthropological Sciences.
