Phys.org / 'Virgin' frescoes emerge from Pompeii suburb
Amid the remains of a sumptuous villa near Pompeii, the hard-hatted conservationist scraped away centuries-old ash to reveal a vibrant red fresco.
Phys.org / Gravitational lensing technique unveils supermassive black hole pairs
Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that closely orbit each other have ...
Phys.org / Cutting down on quantum-dot crosstalk: Precise measurements expose a new challenge
Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now shown how quantum information ...
Phys.org / Photonic integrated circuits enable programmable non-Abelian 'braiding' of light states
A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of operations depends on ...
Phys.org / New 3D printing ink uses 70% lignin and recycles with water
Additive manufacturing (AM) methods, such as 3D printing, enable the realization of objects with different geometric properties, by adding materials layer-by-layer to physically replicate a digital model. These methods are ...
Phys.org / Silicon metasurfaces boost optical image processing with passive intensity-based filtering
Of the many feats achieved by artificial intelligence (AI), the ability to process images quickly and accurately has had an especially impressive impact on science and technology. Now, researchers in the McKelvey School of ...
Phys.org / A new microscope for the quantum age: Single nanoscale scan measures four key material properties
Physicists in Leiden have built a microscope that can measure no fewer than four key properties of a material in a single scan, all with nanoscale precision. The instrument can even examine complete quantum chips, accelerating ...
Phys.org / Where'd you get that frog? Study traces illicit online amphibian trade
Keeping amphibians as pets offers hobbyists an opportunity to connect with the non-human world, often increasing interest in conserving animals in the wild. But there's a dark side to the amphibian trade, according to a study ...
Phys.org / Physicists develop new protocol for building photonic graph states
Physicists have long recognized the value of photonic graph states in quantum information processing. However, the difficulty of making these graph states has left this value largely untapped. In a step forward for the field, ...
Phys.org / The changing chemistry of invasive death cap mushrooms
The California Department of Public Health reported 39 related poisonings in the last three months, leading to the death of four people, at least three liver transplants, and many more people made sick. The culprit? In each ...
Phys.org / Noisy classroom? Study suggests engagement matters more than eliminating background noise
How well we pay attention while learning is influenced not only by external distractions like background noise but also by internal factors such as how interesting we find the material, according to a study recently published ...
Phys.org / Yangtze River fishing ban halts seven decades of biodiversity decline
The Yangtze River Basin, a global biodiversity hotspot, has endured severe ecological degradation over several decades due to intense human activity, leading to a marked decline in aquatic biodiversity. In order to halt this ...
