Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia

Ancient DNA reveals Indigenous dog lineages found at Jamestown, Virginia

Previous scientific studies have indicated that North American dog lineages were replaced with European ones between 1492 and the present day. To better understand the timing of this replacement, researchers from the University of Illinois Urbana-Champaign and the University of Iowa sequenced mitochondrial DNA from archaeological dogs. Their findings suggest a complex social history of…

Researchers investigate parent perceptions of virtual learning

In response to the COVID-19 pandemic, a majority of schools across the U.S. shifted to virtual learning. In a new study, published in Social Education Research, researchers conducted interviews with parents of students who attended middle or high schools to understand how virtual learning impacted their daily routines, stress levels, and the academic performance of…

New AI tool captures how proteins behave in context

A fish on land still waves its fins, but the results are markedly different when that fish is in water. Attributed to renowned computer scientist Alan Kay, the analogy is used to illustrate the power of context in illuminating questions under investigation. A fish on land still waves its fins, but the results are markedly different…

Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth’s mantle

For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds. For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth’s lower mantle scatter…
