Active Field Theory Approach to Explain Size Control of Transcriptional Condensates

Macromolecular Bioscience, Volume 26, Issue 10, October 2026.
Transcriptional condensates are highly dynamic but resist coarsening in living cells, and high‐resolution microscopy reveals an exponential size distribution in steady state. This size control might be related to reverse Ostwald ripening, a genuine non‐equilibrium mechanism that arrests coarsening.

High‐Temporal‐Resolution Monitoring of Creatine and Phosphocreatine Dynamics in Skeletal Muscle Using Ultrafast Z‐Spectroscopy (UFZ) CEST MRI at 3T

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1798-1805, October 2026.
ABSTRACT Purpose To evaluate the feasibility of High‐Temporal‐Resolution (HTR) Ultrafast Z‐spectrum (UFZ) CEST MRI for monitoring the dynamic fluctuations of phosphocreatine (PCr) and creatine (Cr) in human skeletal muscle (SM) at 3 T during and after exercise.

The Filler Network Index: A Viscosity‐Independent Rheological Criterion for Quantifying Silica Architecture in Unvulcanized Rubber Compounds

SPE Polymers, Volume 7, Issue 4, October 2026.
SEM images of unmodified (U30) and TESPT‐grafted (U30‐SCA) silica compounds show that pre‐grafting eliminates agglomerates. Stress relaxation data fitted with a constrained five‐element Weichert model give discrete relaxation times (τ1$$ {\tau}_1 $$‐τ5$$ {\tau}_5 $$), both reduced by grafting. Their ratio, the Filler Network Index (FNI = τ1$$ {\tau}_1 $

The Lord of the Rings: Cysteine bonds crosslink the tail of siphovirus

Protein Science, Volume 35, Issue 10, October 2026.
Abstract Long, non‐contractile tails composed of helical hexameric protein repeats that assemble into continuous tubular structures characterize siphoviruses. The siphovirus tail tube protein gp39 contains two cysteine residues per monomer. Cryo‐electron microscopy revealed that these cysteines are oriented toward the interface between the rings, which

Generalizing the Gaussian Network Model: Spanning‐Tree Thermodynamics Shows Entropy‐Driven KRAS Activation

Proteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1671-1685, October 2026.
ABSTRACT The GTPase KRAS executes a conformational switch between a GTP‐bound active state and a GDP‐bound inactive state, a process central to oncogenic signaling. However, the structural basis of this switching at the level of residue‐contact organization remains incompletely characterized by traditional binary structural models.
