Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots
Advanced Robotics Research, EarlyView.This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization
Advanced Science, EarlyView.This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Calcite moonmilk of microbial origin in the Etruscan Tomba degli Scudi in Tarquinia, Italy [PDF]
, 2018 A white deposit covering the walls in the Stanza degli Scudi of the Tomba degli Scudi, Tarquinia, Italy, has been investigated. In this chamber, which is still preserved from any kind of intervention such as cleaning and sanitization, ancient Etruscans ...

Advanced Science, EarlyView.This study identifies B4GALNT4 as a key driver of prostate cancer (PCa). It shows that B4GALNT4 glycosylates PDK1 protein at the N531 site, which stabilizes the PDK1 and constitutively activates the PI3K‐AKT pathway. This mechanism promotes tumor cell proliferation, migration, and invasion. The findings establish the B4GALNT4‐PDK1 glycosylation axis as

TriCON: A Carbon‐Based Triple‐Modal Nanoplatform for Pancreatic Cancer Therapy
Advanced Science, EarlyView.We developed TriCON, a triple‐modality nanotherapeutic platform, to treat pancreatic ductal adenocarcinoma (PDAC) by synergizing gene editing, chemotherapy, and immunotherapy. TriCON utilizes CRISPR/Cas9 to target the poliovirus receptor (PVR), combined with nano‐encapsulated doxorubicin and checkpoint blockade. This approach achieved significant tumor

External Intervention and the Duration of Civil Wars [PDF]
, 2020 This paper examines the effect of external intervention on civil war duration from the years 1946-2002. Based on the logic that intervention causes a distortion of the bargaining process in civil wars, it is hypothesized that intervention leads to ...
