Summary: DNA functions only in aqueous environments and adopts different conformations depending on the hydration level. Investigating the impact of hydration on DNA dynamics and the spectral features of water molecules influenced by DNA is challenging. The dynamics of water molecules in a DNA solution is heterogeneous, with four distinct relaxation times ranging from -8 ps to 1 ns, and the hydration structure of a DNA chain can extend to as far as -18 Å from its surface.

Summary: This study shows that electrolytes driven by an external electric field exhibit scale invariance despite Debye screening. Long-range correlations result in a Casimir-like fluctuation-induced force between neutral boundaries that can be controlled by the electric field, behaving differently from other fluctuation-induced forces.

Summary: Substitutions at nonconserved protein positions can have noncanonical and long-distance effects on protein function, potentially resulting from changes in the internal protein communication network and structural flexibility. Substitutions were found to have long-range effects on flexibilities and dynamic coupling of DNA-binding positions, with the degree of flexibility change correlating with experimentally measured changes in DNA binding. This study proposes that long-range and noncanonical substitution outcomes arise from rewiring long-range communication among functionally important positions.

Summary: In this study, the authors investigate three different T-loop receptor motifs found in FMN and Cbl riboswitches using a cell-based genetic screen and bioinformatic analysis. They find clear sequence signatures for these receptor motifs that align with phylogenic analysis and identify functional differences in TL/TLR interactions within the riboswitch subclass.

Summary: This study demonstrates that in deep eutectic solvents, electrostatic correlations can prevail over long-range electrostatic interactions, and specific counterion condensation can modulate micelle morphology and electrostatic interactions. These findings are rationalized in terms of predominant ion-ion correlations and specific ion effects described by the Hofmeister series.

Summary: The study explores the role of protein-protein interactions between transcription factors in enhancer regulation and develops a predictive model for enhancer-promoter interactions. The model shows superior performance, identifies specific TF PPIs involved in long-range regulation, and reveals new mechanistic understandings of enhancer regulation.

Summary: The isotropic and anisotropic coefficients C-n(l,m) of long-range spherical expansion in the dispersion and induction intermolecular energies are calculated for complexes containing aromatic molecules and alkali or alkaline-earth-metal atoms. The properties of the aromatic molecules and alkali or alkaline-earth-metal atoms are obtained using response theory and analytical wavefunctions. The dispersion and induction coefficients with n > 6 are shown to be important for accurately predicting interaction energy in the van der Waals region at R approximate to 6 A. These long-range potentials are valuable for spectroscopic and scattering studies.

Summary: In this study, we investigate quantum phase transitions in Heisenberg antiferromagnetic chains with staggered power-law decaying long-range interactions. By using the density-matrix renormalization group (DMRG) algorithm and the fidelity susceptibility as the criticality measure, we obtain more accurate values of quantum critical points compared to previous studies. Furthermore, we explore the effects of anisotropic long-range interactions and symmetry breaking, which result in the emergence of various quantum phases.

Summary: The study introduces an objective method for distinguishing between chemotactic approach and blind migration based on the analysis of time-lapse recorded cell migration trajectories. The method was validated with simulated data and successfully applied to detect long-range interactions in collective systems of self-driven agents in experiments.

Summary: The study theoretically explores quantum states of a pair of photons interacting with a periodic array of two-level atoms in a waveguide, revealing irregular wave functions and the breakdown of Bethe ansatz, leading to quantum chaos. The long range waveguide-mediated coupling between atoms is identified as the key factor for chaos and nonintegrability in this system, providing new insights into the interplay between order, chaos, and localization in many-body quantum systems.

Summary: The study examines relativistic anyons in 1+1 dimensions, extending well-known models of Dirac fermions. It shows that anyonic statistics allows one to approach off-diagonal long-range order, but this possibility is disrupted by gauge coupling. The presence of a nonzero effective mass due to gauge invariance also implies screening effects independent of anyonic statistics.

Summary: Tailoring hopping interactions between constituent elements of a physical system is crucial for observing unusual phenomena. Through the use of non-Hermitian concepts, tailored asymmetric interactions have been realized in photonic integrated platforms, enabling the induction of topological behaviors and the observation of topological responses.
