Electromagnetic pulses (EMPs) generated from nuclear explosions, high-power electromagnetic pulse devices, and intentional electromagnetic interference can significantly impact civilian and military infrastructure. Recently, researchers from the Republic of Korea and the USA have developed a transparent glass window based on an asymmetric hexagonal metal mesh film with ultra-wideband EMP-shielding capabilities for infrastructure protection. Notably, the proposed innovation is resistant to humidity, mechanical abrasion, and corrosive species.

By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light – and, as a result, its electronic and optical properties. This is shown by a study from Umeå University published in Nature Communications.

Low algal growth despite high iron supply: A new study in Nature Geoscience uncovers a surprising link between West Antarctic Ice Sheet retreat and the growth of marine algae over the past 500,000 years. The team's findings suggest that global warming could potentially result in a reduced uptake of carbon dioxide in the Pacific sector of the Southern Ocean if the West Antarctic Ice Sheet, which is considered unstable, continues to shrink. 

Researchers employed the Einstein-Maxwell-Dilaton (EMD) holographic QCD model combined with Bayesian analysis to conduct a detailed investigation into the thermodynamic properties and dissociation processes of heavy quarkonium as it traverses the Quark-Gluon Plasma (QGP) medium during relativistic heavy-ion collisions. The study primarily calculated thermodynamic quantities such as the dissociation distance, potential energy, and binding energy of heavy quarkonium under varying temperatures and chemical potentials. The results indicate that increasing temperature and chemical potential reduce the dissociation distance of heavy quarkonium while suppressing its potential and binding energies. This demonstrates that elevated temperature and chemical potential significantly promote the dissociation of heavy quarkonium, thereby providing clearer insights into the influence of color screening effects in the QGP medium on the stability of heavy quarkonium. This study represents the first systematic quantification of the effect of chemical potential on the dissociation process within a holographic framework, offering key theoretical predictions for understanding the properties of QGP in high baryon density regions.

Coherent laser ranging systems confront a fundamental trade-off: higher resolution typically comes with increased system complexity and cost. Researchers from Tsinghua University have demonstrated a cavity dynamics-based approach that breaks this limitation. By reinjecting target-scattered light into the laser cavity, their system actively generates interference harmonics that multiply phase sensitivity, achieving over 10-fold resolution enhancement without additional hardware. This elegant approach unlocks new avenues for high-resolution, cost-effective ranging in autonomous systems and precision measurements.

Researchers have found duality can reveal hidden non-invertible symmetry protected topological phases, unlocking new quantum phases.

By creating a 'little bit of the Universe in a bottle' in her lab, a PhD student in physics has reverse-engineered the chemical cocktails produced by stars to better understand how cosmic dust might have provided the building blocks of life.

Conventional nanoscale electroplasmonic structures provide limited electrical tunability of nonlinear optical responses. Scientists at Japan's Institute for Molecular Science have demonstrated an angstrom-scale electroplasmonic platform enabling giant modulation (2000% V^-1) of near-field nonlinear optical effects across a broad spectral range. The breakthrough provides a novel scheme of highly efficient electro-optical conversion in an infinitesimal spatial scale, laying the foundation for atomic-scale ultracompact electrophotonic information-processing technology.
