Phys.org / Ancient DNA uncovers unknown Argentina lineage that has persisted for last 8,500 years
An area called the central Southern Cone in South America, which consists of a large part of Argentina, is known to be one of the last global regions to become inhabited by humans.
Phys.org / Saturn's icy moon may host a stable ocean fit for life
A new study led by researchers from Oxford University, Southwest Research Institute and the Planetary Science Institute in Tucson, Arizona has provided the first evidence of significant heat flow at Enceladus's north pole, ...
Phys.org / Stone Age Pacific fishing practices revealed through chemical fingerprints hidden in collagen
A new collagen fingerprinting tool can help scientists identify species from archaeological bone fragments. Pacific islanders of the late Stone Age, also known as the Neolithic period, were master fishers. Archaeological ...
Phys.org / Uncovering the genetic mechanism that causes barley crops to sprout early
Every year, billions of dollars' worth of crops worldwide perish due to pre-harvest sprouting (PHS), a phenomenon in which grain or seeds germinate on the plant before harvest. The process is triggered by a variety of factors, ...
Phys.org / Air-filled anomalies in Menkaure Pyramid could indicate a new entrance
Researchers from Cairo University and TUM, as part of the ScanPyramids research project, have identified two hidden air-filled anomalies in the third-largest pyramid of Giza. The hypothesis of a possible entrance at this ...
Phys.org / Cracks in Antarctic 'Doomsday Glacier' ice shelf trigger accelerated destabilization
Thwaites Glacier in West Antarctica—often called the "Doomsday Glacier"—is one of the fastest-changing ice–ocean systems on Earth, and its future remains a major uncertainty in global sea-level rise projections. One ...
Phys.org / Fossil of a baby sea snail inside a mother's shell discovered
Research teams from the Academia Sinica and National Taiwan University have documented the first discovery of five freshwater mollusk species in the Early Pleistocene Tananwan Formation of northern Taiwan. This pivotal finding, ...
Phys.org / Crop rotation delivers higher yields, better nutrition, and increased farm revenues across six continents, study shows
An international study involving INRAE and coordinated by China Agriculture University has shown that the practice of crop rotation outperforms continuous monoculture in terms of yield, nutritional quality and farm revenues. ...
Phys.org / Antarctic ice melt triggers further melting: Evidence for cascading feedbacks 9,000 years ago
A study has revealed that the substantial retreat of the East Antarctic Ice Sheet (EAIS) approximately 9,000 years ago was driven by a self-reinforcing feedback loop between ice melt and ocean circulation.
Phys.org / Evolution of human saliva tracked back to primates
Saliva is a bodily fluid most of us take for granted despite the significant roles it plays: aiding in digestion, maintaining strong teeth and defending against oral disease. However, the evolution of human saliva has been ...
Phys.org / Rare meteoroid impact triggers dust avalanches and new streaks on slopes on Mars
When a meteoroid shook the edge of Apollinaris Mons on Mars, it triggered streaks that carved a hundred new scratches on the surface. The European Space Agency's ExoMars Trace Gas Orbiter captured these dust avalanches on ...
Phys.org / Open-source 'macroscope' offers dynamic luminescence imaging
A team of European researchers has developed a versatile, open-source luminescence imaging instrument designed to democratize access to advanced fluorescence and electroluminescence techniques across disciplines ranging from ...
