Biophysics sits at the fascinating intersection where the laws of physics meet the complexity of living systems. This field uses tools like light, electricity, and mechanical forces to decode how cells move, how proteins fold, and how our senses translate the world around us. Rather than just observing biology, biophysicists measure and model life to understand the fundamental machinery that powers every organism.

On Gist.Science, we make these discoveries accessible by curating the latest preprints directly from bioRxiv. Our team processes every new submission in this category, providing both clear, plain-language overviews and detailed technical summaries so readers of all backgrounds can grasp the cutting-edge science. Below are the most recent biophysics papers from bioRxiv, ready for you to explore.

An Investigation of the Conformational Dynamics of ABC Exporter PCAT1 using Microsecond-Level MD Simulations

By combining microsecond-scale molecular dynamics simulations with free energy perturbation calculations, this study elucidates how Mg2+ coordination and substrate binding cooperatively stabilize the inward-facing conformation of the PCAT1 transporter, identifying Lys525 as the dominant residue for ATP stabilization and providing a comprehensive molecular model of nucleotide recognition in this ABC exporter.

Predicting Binding Affinities for the Binding Domain of Hyperpolarization-Activated Cyclic Nucleotide-Gated Channel Isoforms Using Free-Energy Perturbation

This study utilizes all-atom molecular dynamics simulations and free-energy perturbation calculations to determine the absolute binding free energy of cAMP to the cyclic-nucleotide-binding domains of HCN channel isoforms 1–4, thereby elucidating the molecular mechanisms underlying their differential sensitivities to cAMP modulation.

Characterizing the Conformational Dynamics of an Intrinsically Disordered Localization Sequence

This study demonstrates that while single-residue substitutions in an intrinsically disordered mitochondrial localization peptide do not alter its overall lack of stable folding, they subtly reshape local structural preferences and the underlying free-energy landscape, suggesting a mechanism for modulating targeting efficiency through sequence-dependent conformational bias.

Dissecting Gap Junctional and Ephaptic Contributions to Electrical Conduction in a Novel Cardiomyocyte Pair Model

This study combines a novel Single-on-Paired experimental preparation with computational modeling to demonstrate that ephaptic coupling, mediated by sodium channels in the perinexus, provides substantial support for intercellular cardiac conduction under physiological sodium conditions, particularly when gap junction conductance is reduced.

Validating folding energy estimates as a method for variant interpretation

This study validates the use of FoldX-based folding energy estimates for variant interpretation by demonstrating that, despite moderate overall correlation coefficients, systematic analysis of mega-scale data reveals a strong linear relationship that can be refined by aggregating structural estimates and identifying outliers, thereby establishing a robust framework for flagging low-confidence predictions and improving protein stability assessments.

Social Information Quality and Environmental Volatility Shape Collective Foraging Behavior

Using a multi-agent reinforcement learning model, this study demonstrates that the quality of social information and environmental volatility jointly determine collective foraging strategies, where low-quality cues yield fragile coordination in stable settings while high-quality payoff information enables flexible, adaptive behavioral diversity in volatile environments.

Robust ciliary flows protect early Xenopus embryos from pathogens independent of multiciliated cell patterning

This study demonstrates that robust ciliary flows in early Xenopus embryos provide effective protection against pathogens through a resilient liquid shield driven by overall ciliary velocity, rather than relying on precise multiciliated cell patterning.
