    A billion years arms-race between viruses, virophages, and eukaryotes

    Jose Gabriel Nino Barreat, Aris Katzourakis
    Phylogenetic analyses of the four core virion proteins support a new evolutionary model for the origin of the main groups of eukaryotic viruses in the kingdom Bamfordvirae.

    Uncovering temporal structure in hippocampal output patterns

    Kourosh Maboudi, Etienne Ackermann ... Caleb Kemere
    Machine learning models of coordinated hippocampal ensemble activity during sharp wave ripple activity encode structure that mirrors the place cell map expressed during exploration, and enable a new paradigm for analyzing and understanding this offline activity.

    Predicting individual traits from models of brain dynamics accurately and reliably using the Fisher kernel

    Christine Ahrends, Mark W Woolrich, Diego Vidaurre
    The HMM-Fisher kernel approach leverages individual signatures of brain dynamics for prediction, which can be used, for example, to search for brain dynamics-informed biomarkers of neuropsychiatric disease or predict treatment response.

    Statistical structure of locomotion and its modulation by odors

    Liangyu Tao, Siddhi Ozarkar ... Vikas Bhandawat
    A fly's locomotion can be decomposed into a small number of locomotor features which can be modulated by odors and other sensory information.

    A stochastic neuronal model predicts random search behaviors at multiple spatial scales in C. elegans

    William M Roberts, Steven B Augustine ... Shawn R Lockery
    A stochastic model of locomotory control in C. elegans based on an extensive new set of tracking data can explain and predict effects of ablations and mutations on behavior.

    Linking time-series of single-molecule experiments with molecular dynamics simulations by machine learning

    Yasuhiro Matsunaga, Yuji Sugita
    A general machine learning scheme for integrating time-series data from single-molecule experiments and molecular dynamics simulations is proposed and successfully demonstrated for the folding dynamics of the WW domain.

    Reproducible, data-driven characterization of sleep based on brain dynamics and transitions from whole-night fMRI

    Fan Nils Yang, Dante Picchioni ... Jeff H Duyn
    Whole-night fMRI-based sleep classification uncovers distinct substates within N2 and REM sleep stages, along with a transition structure between them.

    Tripartite organization of brain state dynamics underlying spoken narrative comprehension

    Lanfang Liu, Jiahao Jiang ... Guosheng Ding
    Hidden Markov Modeling to fMRI data reveals how language comprehension arises from the dynamic interplay of large-scale brain networks.

    Thousands of novel translated open reading frames in humans inferred by ribosome footprint profiling

    Anil Raj, Sidney H Wang ... Jonathan K Pritchard
    Over 7,000 novel translated sequences have been identified from human cells, including several hundred in annotated noncoding RNA, pseudogenes and de novo assembled transcripts.

    Sensitive remote homology search by local alignment of small positional embeddings from protein language models

    Sean R Johnson, Meghana Peshwa, Zhiyi Sun
    Protein language deep learning models can quickly and accurately translate amino acid sequences into profile hidden Markov models or a structure alphabet, dramatically improving remote homology search sensitivity without compromising space or time efficiency.
