Science
Simulation examines how tin solder boundaries absorb dislocations
Researchers at Los Alamos National Laboratory and Iowa State University modelled how a (301) twin boundary in β-tin interacts with dislocations. The simulation concerns deformation mechanisms in tin alloys used in electronic solder.
Technology
Competence-aware orchestration adjusts communication in agent teams
The framework changes agent roles and communication patterns according to task-specific capabilities.
Science
New epitaxy method stabilised four metastable crystalline phases
A research team led by MIT used a method it calls diffusion-activated epitaxy to experimentally stabilise four distinct crystalline phases. The preprint says diffraction and microscopy data for three phases did not match structures in the crystal databases examined.
Science
Theory maps how screening charge constrains ferroelectric domain walls
A University of Tennessee materials researcher presented a theoretical framework linking ferroelectric domain-wall motion to changes in surface screening charge. The work analyses how different boundary conditions for charge conservation and transport affect wall motion and stability.
Science
Graph model simulates grain growth faster than phase-field calculations
Researchers at the Hong Kong University of Science and Technology, HKUST Guangzhou and Wuhan University developed a graph-based grain-growth simulation. It updates grain areas using the von Neumann–Mullins law and reconstructs the microstructure with a neural network.
Technology
LongHarness tests evidence management for long-context agents
The framework supports agent answers by updating evidence and conclusions together across long documents.
Technology
Study proposes stricter tests for novelty claims in AI materials discovery
Researchers at the University of Liverpool and University College London used continuous mathematical invariants to compare crystal structures. Their preprint examines two GNoME dataset releases and argues that duplication checks are essential before claiming new materials.
Technology
Meta researchers map cross-service risks in personal agents
X-AgentRed uses tool-dependency graphs and execution feedback to search for potentially harmful workflows.

England drought bulletin reports reservoirs at 54% of capacity
The Environment Agency’s bulletin for 2–8 October said reservoir storage in England remained below its seasonal average and that agricultural concerns about winter water storage persisted.

China’s late-September bulletin shows chemical input rises and agricultural declines
China’s National Bureau of Statistics said prices rose for 22 of 50 monitored industrial and agricultural inputs in the final 10 days of September compared with the previous 10-day period. Five were unchanged and 23 fell.
