Radiation‐Resistant Aluminum Alloy for Space Missions in the Extreme Environment of the Solar System

Advanced Materials, EarlyView.
A novel ultrafine‐grained aluminum crossover alloy exhibits unprecedented radiation resistance and mechanical stability under extreme irradiation doses up to 100 dpa. The exceptional resilience arises from thermodynamically stable T‐phase precipitates, enabling lightweight structural materials for next‐generation spacecraft and extraterrestrial ...

Safe and Localized Lentiviral Gene Delivery via Injectable Mesoporous Scaffolds for Potent Antitumor Immunity

Advanced Materials, EarlyView.
This work introduces an injectable mesoporous silica rod scaffold that confines lentiviral vectors to the injection site, enabling localized dendritic cell recruitment and transduction. The platform sustains antigen expression, promotes robust T‐cell activation, and enhances antitumor immunity.

Cross-species radioprotection: insights from tardigrade multi-omics

Radiation Medicine and Protection
Although the search for appropriate radiation countermeasures has been ongoing for decades, there remains a lack of safe and effective radioprotective pharmaceuticals for preventing, mitigating, or treating acute radiation syndrome (ARS) and other severe

Science‐Towards‐Technology Breakthrough in CO2 Electroreduction: Multiphysics, Multiscale, and Artificial Intelligence Insights

Advanced Materials, EarlyView.
Electrochemical CO2RR is a key technology for converting CO2 into chemicals, but there remains a gap between “laboratory science” and “engineering practice” in current research. This review establishes a multi‐scale research framework, encompassing atomic‐level characterization, microenvironment regulation, external field‐assisted optimization, and AI ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Desiccation Tolerance of Epiphytic Macrolichens in an Evergreen Temperate Rain Forest (Alerce Costero National Park, Chile)

Plants
The Valdivian region has a temperate rainy climate with differences in rainfall throughout the year. This heterogeneity results in periods of summer drought that expose the poikilohydric epiphytes to desiccation.
