Portable UV spectrometer can detect air pollutants across 2.5 km with high precision
Portable UV spectrometer can detect air pollutants across 2.5 km with high precision Sadie Harley Scientific Editor Robert Egan Associate Editor Birgitta Schultze-Bernhardt and her team at the Institute of Experimental Physics at Graz University of Technology (TU Graz) have developed a new type of UV dual-comb spectrometer that detects gaseous air pollutants with unrivaled accuracy and sensitivity. Using ultraviolet double laser light, the device measures the concentration of harmful gases...
Experimental Characterization of Bulk Micromegas for Development of Active Target Time Projection Chamber for Nuclear Astrophysics Studies
arXiv:2602.21238v3 Announce Type: replace Abstract: A Micromegas-based active target Time Projection Chamber, namely Saha Active Target TPC (SAT-TPC), is under development at Saha Institute of Nuclear Physics for its application in nuclear astrophysics experiment to measure the branching ratio of the direct and sequential decay of the Hoyle state of $^{12}$C. A bulk Micromegas was characterized to optimize its operating parameters and its performance for $\alpha$-particle tracking was...
Dynamic terahertz wavefront control using stretchable single-walled carbon nanotube-based metasurfaces
Dynamic terahertz wavefront control using stretchable single-walled carbon nanotube-based metasurfaces Sadie Harley Scientific Editor Alexander Pol Deputy Editor The terahertz (THz) frequency regime, sitting between microwaves and infrared light, has long promised revolutionary advances in wireless communication, security imaging and nondestructive sensing. A key roadblock, however, has been the lack of compact, dynamically tunable components capable of manipulating THz beams on demand....
The secret to pigeons’ incredible navigation was hiding in their liver
The secret to pigeons’ incredible navigation was hiding in their liver Pigeons may owe their remarkable homing ability not to their brains or eyes, but to magnetic-sensing immune cells hidden in their livers. - Date: - May 31, 2026 - Source: - Max Planck Institute of Animal Behavior - Summary: - Scientists have uncovered a surprising navigation system in pigeons: iron-filled immune cells in the liver that may act like tiny magnetic sensors. Birds deprived of these cells struggled to find...
Strange 'spacetime crystals' could give birth to tiny black holes
Strange 'spacetime crystals' could give birth to tiny black holes "Sometimes a tiny, seemingly insignificant cause is enough to trigger a huge and dramatic change." When we think about a black hole, we probably picture some vast cosmic titan, greedily consuming any matter unfortunate enough to fall within its gravitational influence. Thinking deeper, we probably imagine this ravenous cosmic beast forming from the explosive collapse of the core of a massive star.
Quantum shell structure reveals new rule for proton-neutron pairing inside nuclei
Quantum shell structure reveals new rule for proton-neutron pairing inside nuclei Sadie Harley Scientific Editor Robert Egan Associate Editor Nuclear physicists used a little magic in their latest experiment conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, and the result has revealed surprising new information about the behavior of protons and neutrons inside the atom's nucleus. Specifically, the research revealed another requirement that...
Structural basis for chaperone-guided assembly of RNA-induced silencing complex
Abstract The RNA-induced silencing complex (RISC), comprising an Argonaute (AGO) protein and a small RNA, is the central effector in RNA silencing. Small RNAs are loaded onto AGO as bulky duplexes in an HSP70- and HSP90-dependent process1,2,3, but the molecular mechanism remains poorly understood. Here we identify the human AGO–HSP90–p23 complex, which captures AGO in an RNA-free state, termed the AGO maturation complex (AMC).
Improved quantum processor logical error rates via correction and detection
Abstract Performing quantum algorithms for critical problems in physics and chemistry requires substantially lower error rates than the physical error rates of present quantum computers. Achieving such low logical error rates requires quantum error correction1,2 and physical error rates below a critical threshold value3,4,5,6,7,8. We experimentally demonstrate on a trapped-ion quantum charge-coupled device (QCCD)9,10 improvements in logical error rates ranging from 11× to 800× compared with...
Magnon momentum microscopy: A new window into nanoscale spin-wave physics
Magnon momentum microscopy: A new window into nanoscale spin-wave physics Sadie Harley Scientific Editor Robert Egan Associate Editor An international team led by the Max Born Institute has developed a new type of momentum microscopy to image magnons—the quanta of collectively excited spins—directly in two-dimensional reciprocal space using soft X-rays. Owing to its remarkable sensitivity, simplicity, and access to nanometer-scale wavelengths, this novel technique establishes a powerful and...
Scientists discover a hidden quantum world inside cobalt
Scientists discover a hidden quantum world inside cobalt - Date: - June 5, 2026 - Source: - Helmholtz-Zentrum Berlin - Summary: - Scientists have uncovered unexpected quantum complexity inside cobalt, a metal long thought to be fully understood. Advanced measurements revealed a dense network of topological electronic states that remain robust at room temperature. These states enable extremely fast electron behavior and can be switched or controlled using magnetism.
