A team of physicists from the University of Ottawa have developed a new theoretical model that shines new light on how scientists understand the way lasers interact with dense matter, such as solids and liquids. This could unlock advances in ultrafast physics and next-generation technology.
Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional polarization-based entanglement states are not stable over long fiber networks. While time-bin entanglement offers a promising alternative, it requires complex infrastructure. In this study, researchers explore how stable time-bin entangled states can be generated and distributed using commercially available components, paving the way for practical quantum communication networks.

Astrophysicists from the University of Waterloo have observed a new jellyfish galaxy, the most distant one of its kind ever captured. Jellyfish galaxies are named for the long, tentacle-like streams that trail behind them. They move quickly through their hot, dense galaxy cluster, and the gas within the cluster acts like a strong wind pushing the jellyfish galaxy’s own gas out the back, forming trails. The technical term for this process is ram-pressure stripping. The Waterloo scientists found this galaxy in deep space data captured by the James Webb Space Telescope (JWST). It is at z = 1.156, meaning we’re seeing it as it was 8.5 billion years ago, when the universe was much younger.
Imagine a “smart fluid” whose internal structure can be rearranged just by changing temperature. In a new study published in Matter, researchers report a way to overcome a long-standing limitation in a class of “smart fluids” called nematic liquid crystal microcolloids, allowing for reconfigurable self-assembly of micrometer-sized particles dispersed in a nematic liquid crystal host.
Researchers at the Department of Energy’s Oak Ridge National Laboratory, working with international partners, have uncovered surprising behavior in a specially engineered crystal. Composed of tantalum, tungsten and selenium—elements often studied for their potential in advanced electronics—the crystal demonstrates an unexpected atomic arrangement that hints at novel applications in spin-based electronics and quantum materials.
When an electron travels through a polar crystalline solid, its negative charge attracts the positively charged atomic cores, causing the surrounding crystal lattice to deform. The electron and lattice distortion then move together through the material—like a single object. Physicists call these quasiparticles polarons. A team led by Professor Jochen Feldmann from LMU has succeeded in tracking the extremely brief formation process of this object for the first time, using an ultrafast imaging method.
Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the magnetic fields that hold the plasma in its doughnut shape, they stream down toward the exhaust system, known as the divertor. There, plasma particles strike metal plates, cool down and bounce back. (The returning atoms help fuel the fusion reaction.) But experiments consistently show that far more particles hit the inner divertor target than the outer one.

Dark energy is one of those cosmological features that we are still learning about. While we can’t see it directly, we can most famously observe its effects on the universe—primarily how it is causing the expansion of the universe to speed up. But recently, physicists have begun to question even that narrative, pointing to results that show the expansion isn’t happening at the same rate our math would have predicted.
Scientists have produced the first global map and analysis of small mare ridges (SMRs) on the moon, a characteristic geological feature of tectonic activity. Published in The Planetary Science Journal Dec. 24, 2025, the analysis performed by scientists at the National Air and Space Museum’s Center for Earth and Planetary Studies and colleagues reveals for the first time that SMRs are geologically young and are widespread across the lunar maria—the vast, dark plains on the moon’s surface. The team’s discovery of how SMRs form introduces a new set of potential moonquake sources that could affect future site selections for lunar landings.
The United Arab Emirates announced on Tuesday that it would extend its Mars probe mission, now in its fifth year, for an additional three, underlining the oil-rich state’s space ambitions.
The low-noise, high-gain properties needed for high-performance quantum computing can be realized in a microwave photonic circuit device called a Josephson traveling-wave parametric amplifier (JTWPA), RIKEN researchers have shown experimentally. This advance stands to speed up development of superconducting quantum computer systems at the 100-qubit scale. The work is published in the journal Physical Review Applied.

Using the Very Large Telescope (VLT), astronomers have discovered a compact binary system consisting of two white dwarfs in the center of a nearby globular cluster designated NGC 6397. The finding was presented in a paper published February 9 on the arXiv preprint server .
