Three years ago, in the waters of the Mediterranean Sea, the passage of an “ultra-energetic” cosmic neutrino was observed — the most energetic ever detected. The event drew international attention from the scientific community as well as from the media and the public, not least because the origin of this particle — whose energy exceeded that of previously observed neutrinos by more than an order of magnitude — is unknown. A new paper published in the Journal of Cosmology and Astroparticle Physics (JCAP) by the KM3NeT collaboration, which operates the KM3NeT/ARCA detector off the coast of Sicily, suggests that the source of this particle may be in a population of blazars — active galactic nuclei hosting a supermassive black hole that emit a plasma jet directed toward Earth.

Researchers present a comprehensive review of frontier AI applications in computational structural analysis from 2020 to 2025, focusing on graph neural networks (GNNs), sequence-to-sequence (Seq2Seq) and Transformer-based architectures, and physics-informed methods. Published in Smart Construction, their work offers a valuable guide for researchers and engineers to understand fundamental concepts, current research status, existing challenges, and future application prospects.

Tokyo, Japan – Scientists from Tokyo Metropolitan University have discovered that a hydrogen-absorbing material shrinks in one direction upon heating, so-called negative thermal expansion (NTE). They found that this NTE is driven by a phase transition in the alignment of magnetic moments, an entirely different mechanism from its hydrogen-free counterpart. Since hydrogenation can be tuned, their findings promise customized high-precision ingredients in materials which don’t change in volume on heating, for next-generation precision nanotechnology.

Scientists have uncovered how different types of biochar influence the movement of water in agricultural soils that contain excessive phosphorus, offering new insights into how farmers can reduce nutrient loss and protect surrounding water bodies.

A recent study, published in Science Advances and co-led by Rice University’s Pengcheng Dai, found that the material cerium magnesium hexalluminate (CeMgAl11O19) was not actually in a quantum spin liquid phase despite evidence suggesting it was. 

Researchers develop hybrid foam with a 3D-printed plastic skeleton—strong enough to save lives, light enough for everyday life.
