    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.

    Adult stem cells and niche cells segregate gradually from common precursors that build the adult Drosophila ovary during pupal development

    Amy Reilein et al.
    Somatic stem and niche cells in the Drosophila ovary develop from common precursors through regulated proliferative expansion, followed by acquisition of position-specific behaviors, rather than through rigid early specification events.

    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.

    First-principles model of optimal translation factors stoichiometry

    Jean-Benoît Lalanne, Gene-Wei Li
    A parsimonious biophysical model correctly predicts the conserved expression stoichiometry of core bacterial mRNA translation factors, providing intuitive and quantitative design principles for in vivo pathway construction.

    Identifying Plasmodium falciparum transmission patterns through parasite prevalence and entomological inoculation rate

    Benjamin Amoah et al.
    Estimating fine-scale spatiotemporal patterns of Plasmodium falciparum transmission showed an association between entomological inoculation rate and parasite prevalence that emphasizes the value of both measures in malaria surveillance.

    Decreased recent adaptation at human mendelian disease genes as a possible consequence of interference between advantageous and deleterious variants

    Chenlu Di et al.
    Harmful genetic variants at mendelian disease genes slow down adaptation, by interfering with the spread of adaptive variants in a population.

    Neuropsychological evidence of multi-domain network hubs in the human thalamus

    Kai Hwang et al.
    Lesions to the anterior-medio-dorsal thalamus cause widespread behavioral impairments across multiple cognitive domains, suggesting that thalamic hubs are critical for interconnecting diverse cognitive processes.

    Experience-dependent weakening of callosal synaptic connections in the absence of postsynaptic FMRP

    Zhe Zhang et al.
    Postnatal, postsynaptic loss of FMRP specifically weakens callosal synaptic inputs onto L2/3 pyramidal neurons, in requirement ofnormal sensory experience, through downregulating AMPA receptor transmission and without affecting local synaptic inputs during cortical circuit development.

    Modulation of fracture healing by the transient accumulation of senescent cells

    Dominik Saul et al.
    Senescent cells accumulate in the fracture callus and a reduction in the number of these cells accelerates fracture healing in mice.

    Multiscale analysis reveals that diet-dependent midgut plasticity emerges from alterations in both stem cell niche coupling and enterocyte size

    Alessandro Bonfini et al.
    The nutrient composition of food alters both the size of gut epithelial cells and the ability of the stem cell niche to control tissue turnover, resulting in changes in size at the organ level.
