Phys.org / Iron Age dental plaque reveals Scythians consumed milk from horses and ruminants
Researchers have deciphered the diet of an important nomadic people in Eastern European history. By analyzing dental calculus, they have provided the first direct evidence that the diet of the Scythians included milk from ...
Phys.org / Scientists design molecules 'backward' to speed up discovery
Every medication in your cabinet, every material in your phone's battery, and virtually every compound that makes modern life work started as a molecular guess, with scientists hypothesizing that a particular arrangement ...
Phys.org / US forests store record carbon as natural and human factors combine
U.S. forests have stored more carbon in the past two decades than at any time in the last century, an increase attributable to a mix of natural factors and human activity, finds a new study.
Phys.org / 2.6-million-year-old Paranthropus fossil expands early hominin range
In a paper published in Nature, a team led by University of Chicago paleoanthropologist Professor Zeresenay Alemseged reports the discovery of the first Paranthropus specimen from the Afar region of Ethiopia, 1,000 km north ...
Phys.org / Low-platinum catalyst could make hydrogen production cheaper
A new type of catalyst that uses five times less platinum than usual could help make hydrogen production more affordable in the future.
Phys.org / Velocity gradients prove key to explaining large-scale magnetic field structure
All celestial bodies—planets, suns, even entire galaxies—produce magnetic fields, affecting such cosmic processes as the solar wind, high-energy particle transport, and galaxy formation. Small-scale magnetic fields are ...
Phys.org / Positive interactions dominate among marine microbes, six-year study reveals
A six-year analysis of marine microbes in coastal California waters has overturned long-held assumptions about how the ocean's smallest organisms interact.
Phys.org / New method creates acinar cells involved in formation of pancreatic cancer
Organoids are three-dimensional miniature models of organs, grown in a dish. They have become a valuable tool for studying human development, organ regeneration, function, and disease progression. Organoids derived from patient ...
Phys.org / How early cell membranes may have shaped the origins of life
Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This complexity allows cells ...
Phys.org / Fossil shorebirds reveal Australia's ancient wetlands lost to climate change
Flinders University paleontology researchers—with local fossil experts—have discovered how prolific shorebirds, including the Plains-wanderer, once lived across South Australia's South-East during wetter times up to 60,000 ...
Phys.org / Data-driven analysis reveals three archetypes of armed conflicts
The language used to describe conflicts naturally reflects assumptions about how different forms of violence emerge and develop.
Phys.org / Sculpting complex 3D nanostructures with a focused ion beam
Scientists from the RIKEN Center for Emergent Matter Science and colleagues have developed a new way to fabricate three-dimensional nanoscale devices from single-crystal materials using a focused ion beam instrument. The ...
