By focusing on adaptive aerodynamics, the ice-tolerance concept with variable drooping leading edge technology could revolutionize how planes handle icing skies. An ice tolerance solution based on the variable camber leading edge of iced wings is proposed, where the leading edge adapts its camber to counter ice effects. Compared with traditional aerodynamic design for ice tolerance, this concept not only strikes a balance between safety and functionality, but also boosts efficiency even under severe icing conditions.

New research from the University of the Witwatersrand in Johannesburg, South Africa (Wits University), has shown that heavy metals such as lead, arsenic, cadmium and mercury accumulate in the scales of Black Mambas (Dendroaspis polylepis).

The study, conducted on snakes captured in Durban in KwaZulu-Natal and published in Environmental Pollution, was the first of its kind to examine heavy metal accumulation in an African snake species. The results mean that researchers can use scale clippings from these snakes to accurately measure spatial patterns of environmental pollution levels, without harming the snakes. 

A research team from Tsinghua University has developed a compact, zero dead-zone heterodyne grating interferometer for simultaneous three-degree-of-freedom (3-DOF) atomic-level displacement measurement. The system achieves sub-nanometer resolution, outstanding linearity, and exceptional stability over large ranges, with significantly reduced crosstalk errors. This breakthrough paves the way for next-generation lithography, atomic-scale manufacturing, and ultra-precision aerospace metrology.

Researchers at The University of Osaka have discovered a new type of chiral symmetry breaking (CSB) in an organic crystalline compound. This phenomenon, involving a solid-state structural transition from an achiral to a chiral crystal, represents a significant advance in our understanding of chirality and offers a simplified model to study the origin of homochirality. This transformation also activates circularly polarized luminescence, enabling new optical materials with tunable light properties.

A team of researchers has unveiled a powerful imaging technique that captures a full-dimensional portrait of elusive trap states—defects that hinder the performance of perovskite solar cells. By combining scanning photocurrent measurement system (SPMS) with complementary tools like thermal admittance spectroscopy (TAS) and drive-level capacitance profiling (DLCP), the team produced detailed spatial and energy maps of these hidden imperfections. Leveraging these insights, they introduced a passivation strategy using sulfa guanidine molecules that dramatically improved device performance. The result: a record-breaking solar cell achieving 25.74% efficiency. This breakthrough not only unlocks a deeper understanding of device physics but also provides a practical pathway to next-generation solar technologies.
