Thanks to NASA’s James Webb Space Telescope, researchers at Embry-Riddle Aeronautical University have observed four additional Wolf-Rayet systems. Each has several visible dust shells around it, similar to the one found around Wolf-Rayet star WR-140.

As urban drone logistics becomes a practical reality, balancing economic cost, ground safety risk, and noise impact poses a systemic challenge. A recent study proposes a novel approach to design urban low-altitude logistics networks, incorporating noise constraints into a multi-objective optimization framework. By combining a layered network model with a dual-population co-evolutionary algorithm, the research provides a new direction for the low-altitude logistics infrastructure of future cities.

Using a combination of telescopes, including the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, and the SOAR telescope at Cerro Tololo Inter-American Observatory in Chile, a Program of NSF NOIRLab, astronomers have characterized the closest supernova linked to a fast X-ray transient. The observations reveal that these bright blasts of X-rays may be the result of a ‘failed’ explosive death of a massive star.

“Space ice” contains tiny crystals and is not, as previously assumed, a completely disordered material like liquid water, according to a new study by scientists at UCL (University College London) and the University of Cambridge.

Aircraft conceptual design is a highly complex process involving multidisciplinary trade-offs and creative thinking. Recent advances in generative artificial intelligence (AI) provide promising opportunities to automate and augment this process. A new study, recently published in the Chinese Journal of Aeronautics, presents an AI-driven framework capable of generating aircraft configuration schemes based on design requirements, integrating aerodynamic knowledge and system constraints. This research fills a key gap in intelligent design methodology, offering a new tool to revolutionize the early stages of aircraft development.
