    Nature Physics is taking part in Guided Open Access (OA), a pilot designed to make the process of publishing open access simpler, quicker, and more efficient. In Guided OA, an article is considered collaboratively at a group of associated journals, and authors are then guided through the process to find the best home for their work.

Nature Physics is a Transformative Journal; authors can publish using the traditional publishing route OR via immediate gold Open Access.

Our Open Access option complies with funder and institutional requirements.

  • Information theory sets an upper limit on the ability of bacteria to navigate up chemical gradients. Experiments reveal that cells do so at speeds within a factor of two of the limit, suggesting they are selected to efficiently use information.

  • A search for axion-like dark matter with a quantum sensor that enhances potential signals is reported. This work constrains the parameter space of different interactions between nucleons and axion-like particles and between nucleons and dark photons.

  • Active fluids exhibit properties reminiscent of equilibrium systems when their degrees of freedom are statistically decoupled. A theory for the fluctuating hydrodynamics of these fluids offers a probe of their anomalous transport coefficients.

    • Superconductivity and ordered states formed by interactions—both of which could be unconventional—have recently been observed in a family of kagome materials.

      Perspective
    • Solitary waves — solitons — occur in a wide range of physical systems with a broad array of attributes and applications. Carefully engineered light–matter interactions have now produced an optomechanical dissipative soliton with promising properties.

    • Charge density waves are the periodic spatial modulation of electrons in a solid. A new experiment reveals that they can originate from two different electronic bands in a prototypical transition metal dichalcogenide, NbSe2.

    • To test the validity of theoretical models, the predictions they make must be compared with experimental data. Instead of choosing one model out of many to describe mass measurements of zirconium, Bayesian statistics allows the averaging of a variety of models.

    • The detailed structure of each atomic species determines what physics can be achieved with ultracold gases. This review discusses the exciting applications that follow from lanthanides’ complex electronic structure.
