Phys.org / Archaeologists unearth evidence of dogs being traded within Mayan societies
A University of Calgary archaeologist has found evidence that the Classic Period Maya were trading live dogs over long distances between the northern Yucatan peninsula and central Chiapas regions.
Phys.org / Tree communities shape hidden energy flows under European forests
Mixing tree species can lead to better growth in the forest—at least above ground. A new study published in Nature shows that mixed forests had lower activity in the complex belowground ecosystems than previously thought. ...
Phys.org / Why twisted bilayer graphene stops superconducting near high-dielectric substrates
Superconductors are materials that can conduct electricity with a resistance of zero. In so-called conventional superconductors, this occurs at low temperatures when electrons become bound into pairs, known as Cooper pairs.
Phys.org / J1152 is an unusual long-period dwarf nova with recurring eclipses, observations find
Astronomers from the South African Astronomical Observatory (SAAO) and elsewhere have conducted photometric and spectroscopic observations of a cataclysmic variable system designated SRGA J115215.0−510656. Results of the ...
Phys.org / Rare footage of elusive sea-floor creatures and backward-swimming fish captured by compact video-acoustic system
Arctic glacial fjords are hotspots of marine life, yet their seafloor environments remain some of the least explored regions on Earth. Their extreme remoteness and the technical challenges of deep-water observation have led ...
Phys.org / Gut bacteria reveal hidden evolutionary lineages tied to aging and disease
The human gut harbors a complex ecosystem of trillions of microorganisms (the microbiome), which influences digestion, the immune system and metabolism. A research team led by the University of Vienna has used the "reverse ...
Phys.org / Magnetic 'super lenses' open new window on high-temperature superconductors
An international research team, including scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), has achieved a methodological breakthrough in the study of superhydrides, a promising class of superconductors. For ...
Phys.org / A new way to read the universe could sharpen understanding of cosmic expansion and dark energy
An international team led by researchers at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB) has developed a new method that could significantly improve our understanding of the expansion of the universe ...
Phys.org / Hourglass nanographenes unlock strong, robust multi-spin entanglement
Researchers from the National University of Singapore (NUS) and collaborators have developed a predictive design strategy for creating graphene-like molecules with multiple interacting spins and enhanced resilience to magnetic ...
Phys.org / Researchers discover a new pathway to building energy-efficient computing chips
The growing popularity of electronic devices—from fitness trackers and laptops to smartphones—is driving demand for more energy-efficient computing chips. Now, researchers have found a way to change the electronic properties ...
Phys.org / Sound waves create mist that can act like 'plant sunscreen'
RMIT University researchers have developed a new way to coat fragile surfaces, including living plant leaves, using high‑frequency sound waves to create a fine mist that can act like a plant sunscreen.
Phys.org / How the rise of continents may have set the stage for life on Earth
Earth's earliest continents may have set the chemical stage for life by regulating boron levels in ancient oceans, a new study in Terra Nova suggests.
