NCOA4 Accelerates Abdominal Aortic Aneurysm Formation by Regulating Macrophage Activation and Ferroptosis via STAT1–CH25H Axis

Advanced Science, EarlyView.
Under pathological stimulation, NCOA4 in macrophages interacts with STAT1 to promote CH25H transcription. The subsequent increase in 25‐HC production activates macrophages, triggers inflammatory responses and ferroptosis, and accelerates the progression of AAA.

Sonogenetic Control of Engineered Probiotics for the Treatment of MASH by Modulating the Gut‐Liver Axis

Advanced Science, EarlyView.
Researchers developed an engineered probiotic encapsulated in an inulin hydrogel, enabling ultrasound‐triggered intestinal delivery of IL‐22. In MASH model mice, this system remodeled gut microbiota, strengthened the intestinal barrier and reduced portal LPS and hepatic IL‐6.

Targeted Mechanogenetics to Modulate Specific Deep Neural Circuits

Advanced Science, EarlyView.
This study introduces mechanogenetics, a nanobubble‐enhanced sonogenetic strategy for selective modulation of feeding‐related neural circuits in the mouse lateral hypothalamus. Mechanogenetic stimulation modulates feeding behavior through glutamatergic projections from the lateral hypothalamus to the ventral tegmental area, highlighting its potential ...

Ultrasound‐Triggered piRNA Delivery Using Biomimetic Phase‐Changeable Nanoparticles for Theranostics of Myocardial Infarction

Advanced Science, EarlyView.
A biomimetic ultrasound‐responsive piRNA delivery nanoparticle platform (piR‐NPs) enables targeted delivery and ultrasound (US)‐triggered release of piR‐1873 in infarcted myocardium. The released piR‐1873 suppresses Usp2‐mediated RIP1/RIP3/MLKL necroptosis, reduces myocardial injury and fibrosis, and promotes cardiac functional recovery, providing a ...

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
