Structural variations (SVs)—large-scale changes in DNA sequence—play a crucial role in shaping traits such as yield, quality, and environmental adaptation in crops. 

New review shows that guiding pollutant motion with electric fields and 3D-printed hierarchical pores can slash fan energy and double removal rates, offering a practical blueprint for next-generation, low-resistance air purifiers.

Plants rely on efficient internal transport systems to distribute essential mineral nutrients, yet how this distribution is spatially organized within complex plant structures remains poorly understood.

Efficient nitrogen reuse is essential for sustaining growth in evergreen fruit trees, yet how different tissues contribute to seasonal nitrogen supply remains unclear. 

A new potassium-containing copper-zeolite catalyst, Cu-SSZ-39-K, enables major progress in low-temperature diesel NO_xemission control. Its higher fraction of Al in 8-memberedringspromotes the formation of more active [Cu(OH)]⁺-Z species, nearly doubling NO_x conversion at 150-225°C compared with conventional Cu-SSZ-39. The catalyst also maintains highly stable and excellent performance after 800°C hydrothermal ageing.With its enhanced activity and high-yield synthesis, Cu-SSZ-39-K offers a scalable route to cleaner diesel emissions.

Using a symmetry-guided design strategy, a research team led by Prof. Junwei Liu from HKUST has predicted 612 monolayer altermagnets based on the experimentally verified layered altermagnet V₂(Se,Te)₂O. Among them, 79 simultaneously exhibit Dirac-cone energy bands and crystal-symmetry-paired spin-momentum locking, providing novel material platforms for ultrafast, anisotropic, and crystal symmetry tunable spin transport. This work lays out a blueprint for the rational design and a springboard for future experimental synthesis and in-depth probes of monolayer altermagnets.
