Phys.org / First quantum oscillations observed in gallium nitride holes
Gallium nitride, a semiconductor that can operate at high voltages, temperatures, and frequencies, has enabled technologies from LED lighting to high-power electronics. Now Cornell researchers have observed a quantum property ...
Phys.org / Electric current stabilizes spins at unstable points for new types of computing
A research team has discovered a new way to control tiny magnetic properties inside materials using electric current, which could possibly pave the way for new types of computing technologies. The work is based on spintronics, ...
Phys.org / Wildflower folk remedy shows modern potential for tackling antibiotic resistance
Scientists have proven that a wildflower steeped in folklore for its medicinal powers has genuine healing qualities—and the potential to help combat antibiotic resistance. Tormentil, a yellow wildflower found in heath and ...
Phys.org / An end to the battle between touchscreens and long fingernails is on the horizon
Anybody who has tried to use a smartphone or tablet with long nails knows that there's a learning curve. Rather than effortlessly tapping with a fingertip, you must awkwardly lay the pads of your fingers onto the screen. ...
Phys.org / Astrophysicists resolve 'negative superhump' conundrum of deep-space binary star systems
New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Cataclysmic variables (CVs) are binary star systems in which primary stars—incredibly dense and compact white dwarfs—accumulate ...
Phys.org / Study reshapes understanding of interaction between organelles in animal cells
Findings from a new University of Cincinnati study have reshaped the fundamental understanding of how a certain cell organelle prepares its environment for cellular digestion. The study, led by UC's Jiajie Diao, Ph.D. and ...
Phys.org / A sudden surge in luminosity: Stacked dyes hint at brighter organic semiconductors
In nature, a certain size is often a prerequisite for biomolecules to perform their specific functions. For example, for proteins or DNA to fulfill their vital tasks, they must be folded in a precise manner—and this requires ...
Phys.org / Shorebird science and conservation collective shows big data can protect birds
New research from the Shorebird Science and Conservation Collective at the Smithsonian's National Zoo and Conservation Biology Institute (NZCBI), published in the journal Conservation Biology, provides a model for big data ...
Phys.org / Stealth superstorms reveal lightning on Jupiter: Beyond the superbolt
Jupiter's lightning has long been of interest to planetary scientists, as it marks stormy spots where researchers can look to learn more about convection in Jupiter's atmosphere. Observing lightning from a distance can be ...
Phys.org / Drought spurs rise in antibiotic-resistant soil microbes
A new Caltech study indicates that drought increases the abundances of antibiotic-resistant microorganisms in soils, which directly correlates with an increase in antibiotic-resistant infections in hospitals. In other words, ...
Phys.org / Chaos as a matter of direction: Researchers build layered material where order and disorder coexist
Some materials behave unexpectedly. They crack differently than expected, or react in ways that are hard to explain. The answer often lies in their atomic structure. Is it neatly arranged, as in a crystal, or disordered, ...
Phys.org / Superconducting chip generates tunable terahertz waves for compact imaging
A tiny crystal chip which uses terahertz radiation to see clearly through a wide range of materials could find applications in health care, biological research, and security screening. Researchers from Scotland and Japan ...
