Phys.org / Surface-only superconductor is the strangest of its kind
Something strange goes on inside the material platinum-bismuth-two (PtBi₂). A new study by researchers at IFW Dresden and the Cluster of Excellence ct.qmat demonstrates that while PtBi₂ may look like a typical shiny gray ...
Phys.org / Coaxing bilayer graphene into a single diamond-like layer for industrial applications
Graphene's enduring appeal lies in its remarkable combination of lightness, flexibility, and strength. Now, researchers have shown that under pressure, it can briefly take on the traits of one of its more glamorous carbon ...
Phys.org / Tiny antennas bring electrical energy to 'unpowerable' nanoparticles
A new technique uses "molecular antennas" to funnel electrical energy into insulating nanoparticles, creating a new class of ultra-pure near-infrared LEDs for medical diagnostics, optical communications, and sensing.
Phys.org / Soil carbon decomposition varies vastly, holding implications for climate models
Soil stores more carbon than Earth's atmosphere and plants combined, which makes the speed of soil carbon's decomposition an important variable in models used to predict changes to our climate.
Phys.org / Magnetic nanocultures: A tiny lens into the vast world of soil microbes
An estimated 1 trillion species of microorganisms reside on Earth, yet scientists have been able to study less than two percent of them. Because many microorganisms cannot be cultivated in laboratories, researchers at Carnegie ...
Phys.org / Central America's 'five great forests' are lifelines for North America's migratory birds
Every spring, the familiar songs of Wood Thrushes and warblers return to the parks and backyards of eastern North America. But their journey begins far to the south—in the lush, remote forests of Central America that sustain ...
Phys.org / Emerald green degradation in masterpieces: Scientists identify the culprits
An international team of researchers have found what triggers degradation in one of the most popular pigments used by renowned 19th and 20th century painters. Using a multi-method approach, including advanced synchrotron ...
Phys.org / How a plant-parasitic nematode can infect a wide range of organisms
UC Davis nematologists, including Valerie Williamson, professor emerita in the Department of Plant Pathology, and associate professor Shahid Siddique, Department of Entomology and Nematology, have long wondered how a plant-parasitic ...
Phys.org / Webb reveals Apep's four 'spiraling' dust shells shaped by Wolf-Rayet stars
NASA's James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. (The fourth is almost ...
Phys.org / Acoustic waves could be the key to orbitronic devices
Electronics traditionally rely on harnessing the electron's charge, but researchers are now exploring the possibility of harnessing its other intrinsic properties. In a Nature Communications study, scientists from Japan demonstrated ...
Phys.org / Family dogs' ADHD-like traits are linked to learning and self-control
In two newly published studies, researchers at the Department of Ethology, Eötvös Loránd University (Hungary) investigated how family dogs' ADHD-like traits relate to their learning and self-control. Dogs resemble humans ...
Phys.org / Ancient bog growth reveals shifting Southern Hemisphere winds 15,000 years ago
Scientists have revealed that ancient bogs in the Southern Hemisphere hold clues to a major shift in Earth's climate thousands of years ago.
