Phys.org / Entanglement-enhanced optical lattice clock achieves unprecedented precision
Optical lattice clocks are devices that measure the passing of time via the frequency of light that is absorbed or emitted by laser-cooled atoms trapped in a repeating pattern of light interference known as optical lattice.
Phys.org / Physicist delineates limits on the precision of quantum thermal machines
Quantum thermal machines are devices that leverage quantum mechanical effects to convert energy into useful work or cooling, similarly to traditional heat engines or refrigerators. Thermodynamics theory suggests that increasing ...
Phys.org / Astronomers capture an exceptional gamma-ray flare from a blazar
Astronomers have performed very long baseline interferometry (VLBI) observations of a gamma-ray loud blazar known as TXS 2013+370. The observations, posted November 19 on the arXiv preprint server, resulted in the detection ...
Phys.org / Secret behind Temple of Venus's resilient construction uncovered
The material used to build the Temple of Venus in Naples has remarkably endured even as Earth's surface around it sank from volcanic activity, and researchers were curious to know how.
Phys.org / Major droughts linked to ancient Indus Valley Civilization's collapse
Successive major droughts, each lasting longer than 85 years, were likely a key factor in the eventual fall of the Indus Valley Civilization, according to a paper published in Communications Earth & Environment. The findings ...
Phys.org / Unprecedented levels of forever chemicals found in dolphins and whales
New research has revealed that marine mammals who live far below the ocean's surface are not immune from the burden of toxic forever chemicals, with whales and dolphins showing unprecedented levels of PFAS contamination.
Phys.org / Thousands of genomes reveal the wild wolf genes in most dogs' DNA
Dogs were the first of any species that people domesticated, and they have been a constant part of human life for millennia. Domesticated species are the plants and animals that have evolved to live alongside humans, providing ...
Phys.org / Social media research tool can lower political temperature—it could also lead to more user control over algorithms
A new tool shows it is possible to turn down the partisan rancor in an X feed—without removing political posts and without the direct cooperation of the platform.
Phys.org / Watching metal crystals grow inside liquid metal: Imaging technique could boost hydrogen production
If you dissolve sugar in hot water and then cool it down, you'll see pure sugar crystals form while impurities stay in the liquid. You can even watch the beautiful sugar crystals slowly grow in the water.
Phys.org / Meteorite samples are time capsules from the early solar system
When a meteor streaks across the sky, it's not just beautiful. It's nature's way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our ...
Phys.org / Scientists capture the crackling sounds of what they believe is lightning on Mars
Scientists have detected what they believe to be lightning on Mars by eavesdropping on the whirling wind recorded by NASA's Perseverance rover.
Phys.org / DNA transcription is a tightly choreographed event: How RNA polymerase II regulates the dance
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must ...
