Secure Decentralized Key Relaying via Random Walks in Dynamic Semi‐Trusted QKD Networks

Advanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Key Distribution (QKD) provides point‐to‐point, information‐theoretically secure session keys, but distance limitations require trusted relays between remote parties. Can quantum keys be relayed without trusting every intermediate node or depending on a central controller?

The San1 Ubiquitin Ligase Avidly Recognizes Misfolded Proteins through Multiple Substrate Binding Sites

Biomolecules, 2021
Cellular homeostasis depends on robust protein quality control (PQC) pathways that discern misfolded proteins from functional ones in the cell. One major branch of PQC involves the controlled degradation of misfolded proteins by the ubiquitin-proteasome ...

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, Volume 600, Issue 14, Page 2028-2037, July 2026.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Assessment of Exploitation Status and Biological Reference Points in a Data‐Limited Brown Shrimp (Farfantepenaeus californiensis) Fishery of the Gulf of California

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.
ABSTRACT Shrimp fisheries in the Gulf of California underpin a major socio‐economic sector in Mexico, yet their assessment and management are constrained by variable population dynamics and limited species‐ and region‐specific information. For the brown shrimp (Farfantepenaeus californiensis), quantitative evaluations of exploitation status are scarce ...

Factors linked to informal caregiver burden in dementia across Latin America and the Caribbean: A systematic review and meta‐analysis

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract Informal caregivers are central to dementia care in Latin America and the Caribbean (LAC), yet determinants of caregiver burden remain insufficiently characterized. We conducted a systematic review and meta‐analysis of studies examining patient‐ and caregiver‐related correlates of burden in LAC.

Prospects of Quantum Computing

SmartSys, Volume 2, Issue 2, June 2026.
ABSTRACT It has been anticipated that quantum computing (QC) would solve computational tasks involving quantum phenomena intractable for supercomputers based on digital technology. Concurrently, however, the vast development of artificial intelligence (AI) has resulted in systems targeting these real‐world problems with unprecedented progress including

Barriers and Bridges: Black Doulas' Experiences in Healthcare Setting

Birth, Volume 53, Issue 2, Page 407-413, June 2026.
Barriers and Bridges: Black Doulas’ Experiences in Healthcare Settings This quality improvement project explored the experiences of six Black doulas in Nebraska through semi‐structured interviews. Thematic analysis revealed three main themes: (1) Barriers including lack of recognition, integration, and bias; (2) Facilitators such as respect, shared ...

Roles of ER Membrane Protein Complex in Protein Biogenesis and Quality Control in the Lung and Beyond

Cell Proliferation, Volume 59, Issue 6, June 2026.
The endoplasmic reticulum membrane protein complex (EMC) is an evolutionarily conserved, multi‐subunit transmembrane protein complex crucial to membrane protein biogenesis and cellular protein quality control. This review systematically examines the structure, functions and disease‐associated regulatory mechanisms of EMC across multiple organ systems ...
