Crack the Code Behind Hidden Pathways in Everyday Systems
Professor Rao Li found new conditions based on the first Zagreb index that guarantee a graph contains a cycle through every vertex, and derived new upper bounds for that index.

This New Speed Limit Could Change Everything We Know About Space-Time
Dr. Cláudio Nassif Cruz proposes a theory in which an unattainable minimum speed is built into space-time alongside the speed of light, linking hydrogen energy levels to the cosmological constant.
Breaking Barriers: Brazilian Team Solves Hilbert’s 16th Problem After 124 Years
Dr. Vinícius Barros da Silva's team proposes that the curvature of a geometric description of polynomial systems reveals how many limit cycles they have and where they lie.
Predicting Weather Disruptions Has Never Been This Accurate Before
Dr. Olga Maltseva's team found that neural networks drawing on data from both directions in time forecast the ionosphere's electron content near the equator more accurately, with less variation between locations.
Conformal Theory of Gravitation and Cosmic Expansion New Light on Dark Matter
Dr. Robert K. Nesbet proposes a conformal theory of gravitation that could explain galaxy rotation and cosmic expansion without invoking dark matter or dark energy, though it still awaits observational testing.
What Scientists Get Wrong About Statistical Evidence and How to Fix It
Professor Michael Evans reviews how statisticians have tried to define statistical evidence and argues that a relative belief approach can reconcile Bayesian and frequentist thinking.
Graviton-like particles found in special liquid could unlock quantum secrets
Professor Kun Yang describes how experiments with polarised light detected graviton-like excitations in fractional quantum Hall liquids, spinning with the chirality that theory predicted for each liquid.
Improving the durability of superconductors with optimized solder joints
Professor Mingzhi Guan's team used computer modelling to show that shorter solder joints with thinner solder reduce stress at joint edges in superconducting tapes, lowering the risk of early failure.
Nankai Physicists Propose Novel Spin Vector Potential in Quantum Mechanics
Professor Jing-Ling Chen's team proposes that particles with spin create a spin vector potential, which could be detected through a spin version of the Aharonov-Bohm double-slit effect.
The Physics Behind Space-Time’s Mathematical Framework
Dr. Rathindra Nath Sen argues that the differential structure of space-time may follow from the principle of causality, while acknowledging that the question remains open.
Discovery of Cosmic Ray Suggests Electroweak Monopole
Professor Yongmin Cho and Dr. Franklin Cho propose that an ultra-high-energy cosmic ray detected by the Telescope Array could be an electroweak monopole left over from the early universe.
Lorentz Violation Unveils Mysteries of Dark Energy Stars and Prevents Singularity of Black Holes
Dr. Cláudio Nassif Cruz proposes that an invariant minimum speed in spacetime could underpin the condensed core of dark energy stars, offering a theoretical way around black hole singularities.
