Using a deep learning AI model, researchers identified the first-of-its-kind biomarker of chronic stress detectable through routine imaging, according to research being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Research teams from Swinburne University of Technology and University of Southern Queensland have provided a deep overview of the current state of the art of fire-retardant recyclable epoxy systems (FRREs) based on covalent adaptable networks. By integrating dynamic covalent bonds (DCBs) and flame-retardant groups into the epoxy crosslinking network can effectively improve fire safety and recyclability. However, how to balance the recyclability, flame retardancy, and network stability of FRREs remains a key challenge. This review provides valuable insights into the directional design of high-stability FRREs.

A joint research team led by Dr. Hee-Eun Song of the Photovoltaics Research Department at the Korea Institute of Energy Research (President Yi Chang-Keun, hereafter “KIER”) and Prof. Ka-Hyun Kim of the Department of Physics at Chungbuk National University (President Koh Chang-Seup, hereafter “CBNU”) has successfully identified, for the first time, the specific types of defects responsible for efficiency loss in silicon heterojunction (SHJ) solar cells. The findings are expected to significantly contribute to improving solar cell efficiency when combined with defect-suppression (passivation) techniques.

In an era where climate change looms large, the aviation industry—responsible for 3%–4% of global CO2 emissions and growing—faces immense pressure to go green without grounding our connected world. Aviation powers trillions in economic activity and millions of jobs, yet its reliance on fossil fuels spews not just CO2 but also NOx, particulates, and other pollutants that harm air quality and accelerate global warming. Enter hydrogen: a boundless, clean-burning fuel that could slash in-flight emissions to zero. But harnessing it means conquering storage challenges onboard aircraft. This survey dives into cutting-edge hydrogen tank technologies, exploring how to safely store gaseous or liquid hydrogen amid extreme pressures and frigid temperatures, all while integrating seamlessly into plane designs. By reviewing materials, structures, and innovations, it highlights hydrogen's role in aligning aviation with global sustainability goals, making eco-friendly flights not just a dream, but an impending reality.

A Korean research team, raising the question “Which OLED light color can actually improve memory and pathological markers in Alzheimer’s patients?” has identified the most effective OLED color capable of enhancing cognitive function using only light—with no drugs involved. The OLED platform developed for this study can precisely control color, brightness, flicker frequency, and exposure duration, suggesting potential future development into personalized OLED-based electroceuticals.
