Researchers found that toxic metal particles in rural North China air are smaller and potentially more harmful than those in urban areas. The study showed that village pollution was strongly linked to biomass and coal burning, while urban pollution was mainly associated with dust-related mineral particles. The findings highlight the overlooked health risks faced by rural populations exposed to PM_2.5-bound heavy metals.

Xuebijing injection (XBJ), a clinically widely used traditional Chinese medicine formulation, ameliorates LPS-induced acute lung injury (ALI) through multi-target synergy. It inhibits inflammation and ferroptosis by directly binding to five key proteins (PKM2, ENO1, PBK, EIF3I, Keap1), suppressing the MAPK/NF-κB/NLRP3 signaling axis, restoring alveolar barrier integrity and immune homeostasis, providing new mechanistic evidence and therapeutic prospects for ALI treatment.

A research team has mapped how artificial intelligence is beginning to reshape cardiac arrest care, from early warning and emergency response to cardiopulmonary resuscitation and recovery after survival. By reviewing 114 studies involving more than 9.57 million patients, the study shows that artificial intelligence is most often used to predict cardiac arrest, guide resuscitation decisions, and estimate post-arrest outcomes. The findings suggest that artificial intelligence could become a practical tool for identifying high-risk patients earlier, supporting time-critical decisions during resuscitation, and improving post-arrest care, while also highlighting the need for stronger real-world validation before these tools can be widely adopted in emergency medicine.

This review highlights spider silk as a next-generation eco-smart biomaterial with broad potential across dermatology, cosmetics, aerospace, textiles, and electronics. Owing to its exceptional strength, elasticity, biodegradability, biocompatibility, and low immunogenicity, spider silk is increasingly explored for wound healing, tissue regeneration, drug delivery, scar repair, and smart dermatologic theranostics. In cosmetics, its amino acid-rich structure supports skin hydration, elasticity, and barrier repair. Beyond healthcare, its lightweight strength, thermal stability, optical clarity, and flexibility enable applications in advanced composites, biodegradable sensors, and wearable devices, making spider silk a promising sustainable material for future industries.

As human longevity increases, individuals are increasingly adopting diverse healthcare products to maintain youthful and healthy lives. Examples include wearable devices like smartwatches for real-time health monitoring, various advanced dressings for scarless wound healing, and optical devices for skin care. Focusing on this trend, the researchers of the present study sought to develop a platform that simultaneously achieves scarless wound healing and promotes skin regeneration. This platform is anticipated to be an innovative methodology poised to replace conventional wound dressings..
