    Echolocating bats prefer a high risk-high gain foraging strategy to increase prey profitability

    Laura Stidsholt, Antoniya Hubancheva ... Peter T Madsen
    Greater mouse-eared bats prefer to hunt large ground insects despite high failure rates, but switch to smaller, easily caught flying insects in response to environmental changes.

    Utility of polygenic embryo screening for disease depends on the selection strategy

    Todd Lencz, Daniel Backenroth ... Shai Carmi
    Preimplantation screening of embryos using polygenic risk scores may substantially reduce risk for a given complex disease, but this effect depends on several quantifiable factors and raises significant ethical issues.

    Building resilient cervical cancer prevention through gender-neutral HPV vaccination

    Irene Man, Damien Georges ... Iacopo Baussano
    Shifting from girls-only to gender-neutral HPV vaccination strategy improves the resilience of cervical cancer prevention and enhances progress towards cervical cancer elimination.

    Monkey plays Pac-Man with compositional strategies and hierarchical decision-making

    Qianli Yang, Zhongqiao Lin ... Tianming Yang
    Macaque monkeys play Pac-Man with strategy-based hierarchical decision-making, a cognitive capacity hitherto unknown in them.

    Risk factors relate to the variability of health outcomes as well as the mean: A GAMLSS tutorial

    David Bann, Liam Wright, Tim J Cole
    We provide a tutorial to use GAMLSS, applied using cohort data to study how risk factors may influence both the mean and variability of body mass index and mental health.

    A neural network model of when to retrieve and encode episodic memories

    Qihong Lu, Uri Hasson, Kenneth A Norman
    A neural network showed better prediction of upcoming states when it was selective in when it encoded and retrieved episodic memories, thereby explaining why humans show this selectivity in studies of naturalistic memory.

    Risk-sensitive learning is a winning strategy for leading an urban invasion

    Alexis J Breen, Dominik Deffner
    Animals can thrive alongside humans by being expert judges of risk.
    1. Ecology

    Both prey and predator features predict the individual predation risk and survival of schooling prey

    Jolle Wolter Jolles, Matthew MG Sosna ... Iain D Couzin
    Detailed tracking of live predators attacking live schools of prey reveals the crucial interplay between predator attack strategy and prey behaviour and positioning in determining the predation risk within mobile animal groups.

    Smartphone screen testing, a novel pre-diagnostic method to identify SARS-CoV-2 infectious individuals

    Rodrigo M Young, Camila J Solis ... Luis A Quiñones
    PCR testing for SARS-CoV-2 from samples taken from smartphone screens, Phone Screen Testing, provides a sensitive, cost-effective, simple, and non-invasive new method that could boost COVID-19 mass test screening.

    On the normative advantages of dopamine and striatal opponency for learning and choice

    Alana Jaskir, Michael J Frank
    A computational model of the opponent neural architecture the basal ganglia, in tandem with adaptive dopamine modulation, exhibits robust advantages over traditional learning algorithms and ties together seemingly aberrant behavioral patterns resulting from dopamine and environmental manipulations across species.
