    Little evidence that Eurasian jays protect their caches by responding to cues about a conspecific’s desire and visual perspective

    Piero Amodio et al.
    Across five experiments, Eurasian jays’ caching behaviour provides little evidence of the ability to integrate cues about a potential pilferer’s visual perspective and desire and, challenging previous findings, to respond to either of the two social cues independently.

    A state space modeling approach to real-time phase estimation

    Anirudh Wodeyar et al.
    A statistically principled approach developed to estimate phase of rhythmic signals in real-time shows robustness to multiple sources of error and also provides confidence criteria.

    Transcription initiation at a consensus bacterial promoter proceeds via a ‘bind-unwind-load-and-lock’ mechanism

    Abhishek Mazumder et al.
    Single-molecule fluorescence experiments reveal transcription initiation proceeds via a 'bind-unwind-load-and-lock' mechanism where promoter DNA unwinds outside the RNA polymerase (RNAP) cleft, the unwound template-DNA loads into the cleft, and RNAP 'locks' the template-DNA by closing the RNAP clamp module.

    Learning to stand with unexpected sensorimotor delays

    Brandon G Rasman et al.
    The nervous system can learn to control standing balance with added sensorimotor delays by causally linking delayed whole-body sensory feedback, initially deemed as unexpected, to self-generated balance motor commands.

    Decoding the brain state-dependent relationship between pupil dynamics and resting state fMRI signal fluctuation

    Filip Sobczak et al.
    The variability of the pupil–fMRI relationship was characterized through a combination of clustering and prediction methods, which revealed brain state-specific subcortical and neuromodulatory activation patterns reflected in pupil dynamics.

    Dorsal premammillary projection to periaqueductal gray controls escape vigor from innate and conditioned threats

    Weisheng Wang et al.
    Activity in the hypothalamic dorsal premammillary nucleus predicts future escape from threat, represents escape velocity, and controls escape velocity via a projection to the brainstem.

    Cost-precision trade-off relation determines the optimal morphogen gradient for accurate biological pattern formation

    Yonghyun Song, Changbong Hyeon
    The morphogen profiles that pattern the fruit fly attain desired levels of spatial precision in a cost-effective manner.

    How subtle changes in 3D structure can create large changes in transcription

    Jordan Yupeng Xiao et al.
    Promoter futile cycles can explain how subtle differences in genome folding sometimes generate large difference in gene expression.
