Advanced Science, EarlyView.This study reveals a novel GC therapy targeting cholesterol homeostasis. Inhibiting the SCAP sterol‐sensing domain causes lethal ER stress via cholesterol accumulation, paradoxically forcing continuous synthesis that triggers ferroptosis. The findings link sterol sensing, metabolic dysregulation, and ferroptosis, establishing an anti‐cancer paradigm ...

活动范围对青鳉鱼
Haiyang yu huzhao重尾分布现象广泛存在于自然界的各种生物运动模式之中，重尾分布现象会随环境的变化而变化。鱼类为适应生存环境，往往会选择更加高效的个体运动模式。以青鳉鱼(Oryzias latipes)为研究对象，在相同浅水条件(5 cm)下，控制其活动范围，探究青鳉鱼在不同水域面积(1.0 m×1.0 m、0.6 m×0.6 m、0.4 m×0.4 m、0.2 m×0.2 m以及0.1 m×0.1 m)条件下的运动模式。利用MATLAB软件将青鳉鱼的运动轨迹转换为具体数据，通过移动速度、移动加速度 ...

Advanced Science, EarlyView.Hospital‐treated infections are linked to increased risk of inflammatory bowel disease in a large prospective cohort. This risk differs by infection burden, time since infection, and host immune‐genetic susceptibility. The findings support a multi‐hit pathogenesis model in which severe infection and inherited susceptibility jointly shape inflammatory ...

Advanced Science, EarlyView.GCs reduce Parkin, leading to ACSL4 accumulation and PUFA‐phospholipid‐driven ferroptosis in BMSCs, which impairs osteogenesis and promotes adipogenesis, causing GIOP. Parkin restoration (via OE‐Parkin or Parkin‐LNP@DSS6) ubiquitinates and degrades ACSL4, inhibiting ferroptosis, rescuing bone formation, and rescues GIOP bone loss.

N–O Dual Functional Group Transposition via Energy Transfer Photocatalysis
Advanced Science, EarlyView.N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.
