An ATP‐Driven N Protein–DDX21 Molecular Switch Dynamically Controls SARS‐CoV‐2 RNA G‐Quadruplex Heterogeneity

open access: yesAdvanced Science, EarlyView.
An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

An Oral Antiviral Combination Against Severe COVID‐19 Enabled by the Synergistic Mechanisms of Action of Auranofin and Remdesivir

open access: yesAdvanced Science, EarlyView.
FDA‐approved anti‐inflammatory drug Auranofin inhibits SARS‐CoV‐2 replication by inhibiting viral Main protease activity and Spike processing required for viral entry. It shows strong synergy with nucleoside analogue Remdesivir, due to non‐overlapping mechanisms.

Gapless Complete Genome and Multi‐Omics Illuminate Immune Adaptation and Host‐Virus Interactions in a Coronavirus Reservoir

open access: yesAdvanced Science, EarlyView.
We present a complete T2T genome assembly for a key bat reservoir. Integrating population genomics, comparative genomics, transcriptomics, single‐cell omics, and functional assays, we resolve previously inaccessible genomic regions and identify evolutionary signatures associated with immune adaptation.

CIVILIZAÇÃO NA ENCRUZILHADA: GLOBALIZAÇÃO PERVERSA, DESIGUALDADES SOCIOESPACIAIS E PANDEMIA

open access: yesRevista Tamoios, 2020
Interrogo o período da globalização a partir das iniquidades que tem promovido em todo o mundo, com especial atenção para a periferia do sistema, e o seu ocaso com a chegada da pandemia do Covid19.

CircFAM65A/CANX Condensates Sequester FAM134B to Inhibit ER‐phagy and Suppress Hepatocellular Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
The novel circRNA circFAM65A suppresses HCC progression. Mechanistically, circFAM65A drives CANX phase separation, which recruits FAM134B into condensates and blocks its interaction with LC3, thereby inhibiting ER‐phagy and HCC progression. Importantly, targeted circFAM65A delivery represents a potential therapeutic strategy for HCC.

Beyond Charge: Field‐Effect Transistors in Multimodal Biosensing Platforms for Biomolecular Interaction Studies

open access: yesAdvanced Electronic Materials, EarlyView.
This review summarizes the developments in field‐effect transistor (FET)‐based dual‐mode sensor platforms and what can be learned from them. It identifies charge as a crucial factor in biomolecular interactions at interfaces, outlines the challenges of hybrid systems, and highlights their benefits.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

open access: yesAngewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...
