  1. Heads or tails

    Efficient navigation in magnetotactic bacteria requires an optimal combination of swimming speed, magnetic moment and body size.

  2. Unconscious knowledge

    Sleep improves knowledge transfer in unconscious learning.

  3. Playing it (not) safe

    Individuals adjust their risky choices by mentally simulating how an observer might make a decision.

  4. The gut-brain connection

    Glia cells mediate cytokine signaling between the gut and the brain, linking sleep to inflammation in the gut.

  5. Evolving calcification

    The discovery of calcarin proteins in calcareous sponges highlights gene duplication and neofunctionalization as drivers of parallel biomineralization.

  6. Urine trackers

    A new computer-vision algorithm can track urination and defecation patterns as a marker of social behavior in rodents.

  7. Neurons unwrapped

    The loss of the gene DEGS1 drives neurodegeneration in fruit flies by altering the morphology and function of glial cells.

  8. Balancing social risks

    Individual needs and social context can shape risk-taking behaviour in animals.
