The Moon no longer has a global magnetic field, but lunar rocks and soils still contain records of ancient magnetism. Therefore, studying the magnetic minerals in these samples can help scientists understand how the Moon’s magnetic field evolved over time. Recently, researchers examining impact-glass particles containing metallic iron from Chang’e-6 lunar soil samples discovered face-centered cubic γ-Fe—the first time this iron phase has been identified in natural lunar samples.

Coronary artery disease remains the top global cause of death, yet standard angiography cannot visualize dangerous artery plaque, creating gaps for guiding percutaneous coronary intervention. This narrative review synthesizes 10 years of human studies, clinical trials and consensus documents covering established and emerging intravascular imaging plus computational tools. Hybrid catheter systems have completed first‑in‑human testing, while artificial‑intelligence plaque analysis delivers diagnostic accuracy comparable to expert readers. These technologies enable combined anatomical, compositional and functional vessel assessment, though broad clinical roll‑out still requires standardized validation and streamlined workflow integration.
