Mechanistic Foundations of KRAS‐Driven Tumor Ecosystems: Integrating Crosstalk among Immune, Metabolic, Microbial, and Stromal Microenvironment

Advanced Science, EarlyView.
KRAS mutations dynamically remodel the tumor microenvironment (TME), fostering immunosuppression, metabolic symbiosis, and stromal plasticity. This review dissects how oncogenic KRAS variants sculpt TME networks and explores actionable vulnerabilities. Emerging strategies combining KRAS inhibitors and TME‐editing approaches offer potential to dismantle

Reduction of discrepancies between students and instructors in the assessment of practical tasks through structured evaluation sheets and peer feedback

Scientific Reports
The aim of this study was to reduce discrepancies between students and instructors in a preclinical dental course by employing structured peer feedback based on a detailed evaluation sheet. In a crossover study of dental students (n = 32), which compared

tRF‐5004b Enriched Secretory Autophagosomes Induce Endothelial Cell Activation to Drive Acute Respiratory Distress Syndrome

Advanced Science, EarlyView.
Acute respiratory distress syndrome (ARDS) is a severe lung condition with limited treatments, often triggered by overactive endothelial cells (ECs). It is identified that macrophage‐derived secretory autophagosomes (MSAPs) exacerbate lung damage by activating EC function.

Covalent Organic Frameworks‐Delivered Reuterin Drives Trained Immunity in Tumor‐Associated Macrophages to Enhance Melanoma Immunotherapy via Glycerophospholipid Metabolism

Advanced Science, EarlyView.
Covalent organic framework (COF)‐reuterin induces trained immunity in tumor‐associated macrophages, promoting the generation of nitric oxide and reactive oxygen species, thereby enhancing the antitumor immune response. Additionally, COF‐Reuterin directly kills tumor cells while simultaneously eradicating pathogenic intratumoural bacteria.

Cryo‐Inactivated Cancer Cells Derived Magnetic Micromotors for Tumor Immunotherapy

Advanced Science, EarlyView.
Cryo‐inactivated cancer cell‐based magnetic micromotors are developed for synergistic tumor immunotherapy via magnetic targeting. These micromotors can induce ferroptosis and immunogenic cell death, deliver tumor antigens, and activate the Mn2+‐dependent cGAS‐STING pathway. The system effectively suppresses tumor progression, recurrence, and metastasis,

Additive Manufactured Magnetoelectric Wireless Retainer as the Periodontal Remodeler for Post‐Orthodontic Tissue Reconstruction and Relapse‐Inhibition

Advanced Science, EarlyView.
Orthodontic relapse persists as a 120‐year challenge, as traditional retainers fail to remodel tissue, causing lifelong dependence. This study demonstrates a flexible magnetoelectric retainer (FMOR) enabling wireless periodontal remodeling. FMOR cues shift periodontal ligament cell (PDLC) paracrine signaling, promoting M2 macrophages, osteogenic ...

Stiffness‐Tunable Neurotentacles for Minimally Invasive Implantation and Long‐Term Neural Activity Recordings

Advanced Science, EarlyView.
A hydraulically actuated “Neurotentacle” probe offers tunable stiffness for precise implantation into the deep brain without rigid shuttles or dissolvable coatings. It stiffens during insertion to penetrate tissue and softens afterward to minimize damage and enable stable long‐term recordings.
