    A Bayesian and efficient observer model explains concurrent attractive and repulsive history biases in visual perception

    Matthias Fritsche, Eelke Spaak, Floris P de Lange
    Attractive and repulsive history biases in visual perception occur simultaneously, yet over dissociable timescales, and are explained by efficient encoding and Bayesian decoding of visual information in a stable environment.

    Present-day central African forest is a legacy of the 19th century human history

    Julie Morin-Rivat, Adeline Fayolle ... Jean-Louis Doucet
    The cessation of major anthropogenic disturbances since European colonization in the forests of central Africa leads to a canopy closing, and to the disappearance of certain light-demanding tree species.

    Action history influences subsequent movement via two distinct processes

    Welber Marinovic, Eugene Poh ... Timothy J Carroll
    Movement biases due to recent action history involve both dynamically-evolving processes reflecting prediction of future actions, and temporally-stable processes induced by movement repetition.

    Introgression shapes fruit color convergence in invasive Galápagos tomato

    Matthew JS Gibson, María de Lourdes Torres ... Leonie C Moyle
    A wild tomato species adopts local fruit color via introgression from an endemic relative, during its invasion onto the Galápagos Islands.

    Megafaunal extinctions, not climate change, may explain Holocene genetic diversity declines in Numenius shorebirds

    Hui Zhen Tan, Justin JFJ Jansen ... Frank E Rheindt
    Application of museomics facilitates characterization of the contribution of historical factors to genetic diversity declines in Numenius shorebirds and highlights that extinction of ecosystem-engineering megafauna may have been detrimental for open-landscape species.

    Demographic history mediates the effect of stratification on polygenic scores

    Arslan A Zaidi, Iain Mathieson
    Correction for stratification in genome-wide association studies should be informed by the demographic history of the sample.

    Diminished responses to bodily threat and blunted interoception in suicide attempters

    Danielle C DeVille, Rayus Kuplicki ... Sahib S Khalsa
    People who have attempted suicide exhibit blunted sensory processing during breathing and pain perturbations, as well as lower heartbeat perception accuracy and reduced mid/posterior insula activity during interoceptive attention.

    The Natural History of Model Organisms: The untapped potential of medaka and its wild relatives

    Leon Hilgers, Julia Schwarzer
    Studies of medaka and other ricefishes in the wild could provide insights in fields such as evolutionary biology, development and cancer research.

    ACC neural ensemble dynamics are structured by strategy prevalence

    Mikhail Proskurin, Maxim Manakov, Alla Karpova
    Anterior Cingulate Cortex displays robust tracking during strategy execution of a summary statistic for that strategy in recent behavioral history, suggesting a role for this brain region in estimating which actions promote the occurrence of events in the environment.

    Preservation of three-dimensional anatomy in phosphatized fossil arthropods enriches evolutionary inference

    Achim H Schwermann, Tomy dos Santos Rolo ... Thomas van de Kamp
    X-ray imaging reveals well-preserved internal characters in mineralized arthropods from the Paleogene, urging the reexamination of previously neglected fossil collections.
