Phys.org / Strontium optical lattice clock exhibits record-high coherence time
Optical lattice clocks are emerging timekeeping devices based on tens of thousands of ultracold atoms trapped in an optical lattice (i.e., a grid of laser light). By oscillating between two distinct quantum states at a particular ...
Phys.org / VERITAS observations explore a unique microquasar
Using the Very Energetic Radiation Imaging Telescope Array System (VERITAS), German astronomers have observed a unique microquasar known as SS 433. Results of the observational campaign, published Sept. 25 on the arXiv pre-print ...
Phys.org / AI tool visually maps science funding and its real-world impacts
The impact of scientific research extends far beyond the laboratory. Breakthroughs like insulin and innovations like the internet have transformed our everyday lives. They also influence policymaking and the overall economy. ...
Phys.org / New species of deep-sea shark and crab discovered off Western Australia
Researchers have described a new species of deep-sea lanternshark and crab, both with the help of specimens collected from a CSIRO-led 2022 voyage of CSIRO research vessel (RV) Investigator.
Phys.org / Researchers unearth origins of Ancient Egypt's Karnak Temple
Researchers have carried out the most comprehensive geoarchaeological survey of Egypt's Karnak Temple near Luxor—one of the ancient world's largest temple complexes and a UNESCO World Heritage site welcoming millions of ...
Phys.org / Quantum uncertainty captured in real time using femtosecond light pulses
Researchers from the University of Arizona, working with an international team, have captured and controlled quantum uncertainty in real time using ultrafast pulses of light. Their discovery, published in the journal Light: ...
Phys.org / From engines to nanochips: Physicists redefine how heat really moves
Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat spreads out smoothly, like water soaking through a sponge. That simple picture, written down by Joseph ...
Phys.org / How black holes produce powerful relativistic jets
A hundred years before the Event Horizon Telescope Collaboration released the first image of a black hole in 2019—located at the heart of the galaxy M87—astronomer Heber Curtis had already discovered a strange jet protruding ...
Phys.org / Researchers integrate waveguide physics into metasurfaces for advanced light control
Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but many conventional designs ...
Phys.org / How the Southern Ocean controlled climate and atmospheric carbon dioxide during the lukewarm interglacials
Earth's climate has fluctuated between cold and warm periods for millions of years. During the so-called "lukewarm interglacials"—warm phases between 800,000 and 430,000 years ago—atmospheric CO2 concentrations were only ...
Phys.org / Third dimension of data storage: Physicists demonstrate first hybrid skyrmion tubes for higher-density quantum computing
Typically, the charge of electrons is used to store and process information in electronics-based devices. In spintronics, the focus is instead on the magnetic moment or on magnetic vortices, so-called skyrmions—the goal ...
Phys.org / The real reasons Endurance sank—study finds Shackleton knew of ship's shortcomings
Sir Ernest Shackleton's ship, Endurance, was crushed by Antarctic sea ice and sank in November 1915. Emblematic of the heroic age of Antarctic exploration, it is widely considered the strongest polar ship of its time, albeit ...
