A study has concluded that the earliest ancestors of anatomically modern humans (Homo sapiens sapiens) emerged in a southern African “homeland” and thrived there for 70,000 years. The breakthrough findings are published in the prestigious journal Nature. The authors propose that changes in Africa’s climate triggered the first human explorations, which initiated the development of ...
Only 15 percent of Australians can balance work and family responsibilities. Young dads consider paid parental leave to look after their kids to be as important to their future success at work as mothers. And it’s the same trend in attitudes to shared household work, according to new research. However, young men without children are ...
Most people only ever encounter rubidium as the purple color in fireworks, but the obscure metal has helped two University of Chicago scientists propose a theory of how the Moon may have formed from studying Moon rocks. Conducted in the lab of Prof. Nicolas Dauphas, whose pioneering research studies the isotopic makeup of rocks from Earth ...
Mothers who drink moderate to high levels of alcohol during pregnancy may be changing their babies’ DNA, according to a Rutgers-led study. Lead author Dipak K. Sarkar, a Distinguished Professor and director of the Endocrine Program in the Department of Animal Sciences at Rutgers University-New Brunswick, said: “Our findings may make it easier to test ...
Conventional wisdom tells us that large objects appear smaller as they get farther from us, but this fundamental law of classical physics is reversed when we observe the distant universe. Astrophysicists at Kent simulated the development of the biggest objects in the universe to help explain how galaxies and other cosmic bodies were formed. By looking ...
A new study from researchers at The University of Manchester investigates the sophisticated network of agents on Twitter who work to distribute fake news during election campaigns. The paper — “Political Astroturfing on Twitter: How to Coordinate a Disinformation Campaign” — was published in the journal Political Communication. “Astroturfing” comes from how agents appear to ...
Researchers have developed a new printer that produces digital 3D holograms with an unprecedented level of detail and realistic color. This new technology could be used to make high-resolution color recreations of objects or scenes for museum displays, architectural models, fine art, or advertisements that do not require glasses or special viewing aids. Research team ...
The use of sugarcane leaves, known as trash or straw, to produce electricity and second-generation (2G) ethanol has been advocated as a means of increasing bioenergy generation without expanding cropland acreage. However, a study conducted in Brazil and published in the journal BioEnergy Research shows that removing straw instead of leaving it on the ground ...
Fire starting is a skill that many modern humans struggle with in the absence of a lighter or matches. The earliest humans likely harvested fire from natural sources, yet when our ancestors learned the skills to set them at will, they had newfound protection, a means of cooking, light to work by, and warmth at ...
Dinosaur footprints found in several European countries, very similar to others in Morocco, suggest that dinosaurs could have been dispersed between the two continents by landmasses separated by a shallow sea more than 145 million years ago. At the end of the Jurassic, as a consequence of the defragmentation of the Pangaea supercontinent, the countries ...
