Phys.org / Novel approach reduces alloy microstructure prediction from years to minutes
For thousands of years, humans have combined metals to collectively harness properties found in individual components, producing such practical materials as bronze, brass and, more recently, steel. However, predicting the ...
Phys.org / Tropical bird migration shaped by stable weather and shifting wind altitudes, study shows
Every year, billions of birds undertake intrepid journeys between temperate regions in North America and their tropical wintering grounds in South America.
Phys.org / Study reveals world's largest turtle nesting site thanks to smarter drone surveys
A University of Florida research team has developed a more accurate way to count wildlife using drones—an innovation that helped confirm the world's largest known nesting site for a threatened turtle species.
Phys.org / Novel feature-extended analysis unlocks the origin of energy loss in electrical steel
Magnetic hysteresis loss (iron loss) is an important magnetic property that determines the efficiency of electric motors and is therefore critical for electric vehicles. It occurs when the magnetic field within the motor ...
Phys.org / Theory for aerosol droplets from contaminated bubbles may shed light on spread of pollution, microplastics, and more
Bubbles burst when their caps rupture. Children discover this phenomenon every summer day, but it also underpins key mechanisms for the spread of pollutants, contaminants, and even infectious disease through the generation ...
Phys.org / Scientists develop technique for high-resolution single cell epigenetic analysis
Van Andel Institute scientists have developed an improved technique to comprehensively profile DNA methylation in single cells, an advance that will help researchers better study the role of epigenetics in cancer and other ...
Phys.org / Study shows that social interaction boosts emotional vitality—but leads to delayed fatigue
Social contact can lift our mood but later leave us drained. A new study has tracked this full emotional sequence in everyday life. Researchers found that being around others boosts emotional energy at the moment, yet contributes ...
Phys.org / Past their prime? Tool use declines with age in wild chimpanzees
New research led by University of Oxford researchers has found that old age likely impacts the habitual tool-use behaviors of some wild chimpanzees—although the extent to which different individuals are affected appears ...
Phys.org / Quantum networks of clocks open the door to probe how quantum theory and curved space-time intertwine
Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect quantum computers globally. ...
Phys.org / World's most precise clock achieves 19-decimal accuracy with aluminum ion technology
There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped aluminum ion. Part of the ...
Phys.org / Neanderthal gene variant lowers muscle enzyme activity in modern humans
The enzyme AMPD1 plays a key role in muscle energy production and normal muscular function. Loss of AMPD1 activity due to genetic mutations is the most common cause of metabolic myopathy in Europeans, occurring at a frequency ...
Phys.org / Astronomers find a giant hiding in the 'fog' around a young star
Astronomers have detected a giant exoplanet—between three and ten times the size of Jupiter—hiding in the swirling disk of gas and dust surrounding a young star.
