In a survey of adults from the countries that comprised the World War II alliances known as the Allies and the Axis, respondents overestimate the importance of their country to the war effort. A new Arts & Sciences study shows how.
Budget cuts at the Internal Revenue Service threaten the agency's effectiveness and have led to billions of dollars in lost tax revenue, new research from the Indiana University Kelley School of Business shows.
'Coprolites' from the Must Farm archaeological excavation in East Anglia, UK, shows the prehistoric inhabitants were infected by parasitic worms that can be spread by eating raw fish, frogs and shellfish.
New research led by Oxford University and Queen Mary University of London has resolved a pig paradox. Archaeological evidence has shown that pigs were domesticated in the Near East and as such, modern pigs should resemble Near Eastern wild boar. They do not. Instead, the genetic signatures of modern European domestic pigs resemble European wild boar.
Archaeologists conducting an ongoing excavation on Jerusalem's Mount Zion have found evidence that appears to be a record of a major biblical event -- the Babylonian conquest and sack of the city in 587/586 BCE that led to the Babylonian Exile. Amid still partially unexcavated Iron Age structures, the researchers found deposits of ash that also included Scythian arrowheads, broken period clay artifacts, and an unusual piece of gold and silver jewelry.
When it comes to cultural heritage sites, there are few things historians wouldn't do to preserve them for future generations. In particular, stone buildings and sculptures made of plaster and marble are increasingly at risk of damage from air pollution, acid rain and other factors. Researchers now report in ACS Applied Nano Materials a new, calcium-based conservation treatment inspired by nature that overcomes many drawbacks of currently used methods.
The team of scientists, led by PhD Student Kimberley Chapelle, recognised that the dinosaur was not only a new species of sauropodomorph, but an entirely new genus. The specimen has now been named Ngwevu intloko which means 'grey skull' in the Xhosa language.
Say you're a scientist who studies the origins and history of food, and you want to communicate to the world your findings that the all-American hamburger -- including the side of fries -- doesn't contain a single ingredient that originally came from the United States. You could publish an article in a top-notch journal, ask a communications officer to write a press release about the paper, or take to Twitter and tell your hundreds of devoted followers.
'Freedom songs' were key in giving motivation and comfort to those fighting for equal rights, in addition to helping empower Black women to lead others when formal leadership positions were unavailable.
The vast cultural and linguistic diversity of Latin American countries is still far from being fully represented by genetic surveys. Western South America in particular holds a key role in the history of the continent due to the presence of three major ecogeographic domains (the Andes, the Amazonia, and the Pacific Coast), and for hosting the earliest and largest complex societies. A new study in Molecular Biology and Evolution reveals signatures of history, ecology and cultural diversity in the genetic makeup of living rural populations.
