UMBC researchers are using NASA’s PACE satellite to map fall colors by tracking changes in leaf pigments like chlorophyll, anthocyanins, and carotenoids. The new method provides more precise timing of peak autumn color than traditional indices, with applications for tourism, monitoring plant stress, and understanding climate impacts.

Researchers from Shanghai Jiao Tong University have successfully utilized a novel screw extrusion-plasticizing friction stir deposition (SEFSD) process to 3D print 5183 aluminum alloy components in the solid state. This innovative approach bypasses the melting phase, significantly reducing common defects like pores and element evaporation. The resulting components showcase a refined microstructure and excellent mechanical properties, paving the way for efficient manufacturing of aerospace and marine structures.
