Superelastic High‐Entropy Oxide Ceramic Aerogels for Thermal Superinsulation and Sealing at Extreme Conditions

Advanced Science, EarlyView.
A high‐entropy oxide ceramic of (Gd1/2Lu1/2)2(Ti1/3Zr1/3Hf1/3)2O7 is prepared through a molecular synthesis route of pyrolytic solid‐solution reactions. The architectured nanofiber aerogel manifests unprecedented thermomechanical properties, including superelastic compressibility of 98% from −196 to 1500 °C, and thermal superinsulation capacity (24.14 ...

Ancient Yersinia pestis genomes from across Western Europe reveal early diversification during the First Pandemic (541–750)

, 2019
The first historically documented pandemic caused by Yersinia pestis began as the Justinianic Plague in 541 within the Roman Empire and continued as the so-called First Pandemic until 750.

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

Advanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

Out-of-pocket payments for health care services in Bulgaria: financial burden and barrier to access.

, 2012
BACKGROUND: In recent years, Bulgaria has increasingly relied on out-of-pocket payments as one of the main sources of health care financing. However, it is largely unknown whether the official patient charges, combined with informal payments, are ...

Where Can Aluminum Go When Batteries Die?

Advanced Science, EarlyView.
Battery‐derived aluminum is transformed from contaminated waste into an alloying resource for high‐performance Fe‐based alloys. Through controlled Al content and processing, dual‐phase austenite/ferrite microstructures with TRIP‐like behavior are achieved.

Addressing Oxygen Embrittlement in Additively Manufactured Titanium via Cu‐Mediated Interstitial Site Engineering

Advanced Science, EarlyView.
A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.
