Nature Physics offers news and reviews alongside top-quality research papers in a monthly publication, covering the entire spectrum of physics. Physics addresses the properties and interactions of matter and energy, and plays a key role in the development of a broad range of technologies. To reflect this, Nature Physics covers all areas of pure and applied physics research. The journal focuses on core physics disciplines, but is also open to a broad range of topics whose central theme falls within the bounds of physics.

  1. A closer look at authorship in <i>Nature Physics</i>
    Nature Physics, Published online: 11 April 2025; doi:10.1038/s41567-025-02895-9 This month, we publish a Comment detailing the proportion of papers published in Nature Physics that have a last author who is a woman. Here, we present our internal data and outline our response and commitments for the future.
  2. Continuous recoil-driven lasing and cavity frequency pinning with laser-cooled atoms
    Nature Physics, Published online: 11 April 2025; doi:10.1038/s41567-025-02854-4 Experiments with cold atoms in optical cavities are often limited to discontinuous operation due to reloading requirements. Now, continuous lasing is demonstrated with strontium atoms in a ring cavity, stabilized by atom loss mechanisms.
  3. Topological dynamics of rapid non-planar gaits in slithering snakes
    Nature Physics, Published online: 10 April 2025; doi:10.1038/s41567-025-02835-7 Snakes are capable of non-planar gaits, such as sidewinding. Now observations of juvenile anacondas reveal another non-planar gait resembling an S shape. Calculations show how topological dynamics of active filaments enable such movements.
  4. Concurrent spin squeezing and field tracking with machine learning
    Nature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02855-3 Simultaneous spin squeezing and the detection of dynamic fields is challenging as entanglement generation and signal interrogation often interfere. An experiment now demonstrates stable spin squeezing and field tracking in a hot atomic ensemble.
  5. Mode-resolved, non-local electron–phonon coupling in two-dimensional spectroscopy
    Nature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02861-5 Probing electron–phonon matrix elements in bulk materials is difficult. Now, an all-optical experimental approach is demonstrated that extracts phonon-mode- and electron-energy-resolved electron–phonon matrix elements in the bulk.
  6. Bacterial second messengers achieve extraordinary signal capacity
    Nature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02856-2 Second messengers are intracellular signalling molecules that relay environmental changes and prompt cellular responses. Through an information-theory framework coupled with quantitative experiments, the second-messenger molecule cAMP, in the bacterium Pseudomonas aeruginosa, is shown to achieve information transmission rates of up to 40 bits per hour.
  7. Resourceful dissipation
    Nature Physics, Published online: 08 April 2025; doi:10.1038/s41567-025-02881-1 Controlled dissipation enables the extraction of equilibrium properties of ultracold one-dimensional gases through the observation of anomalous dynamics.
  8. Marangoni flows underlie symmetry breaking in early mouse gastruloids
    Nature Physics, Published online: 07 April 2025; doi:10.1038/s41567-025-02840-w Spherical aggregates of mouse stem cells exhibit symmetry breaking by forming an elongated axis. This extension is driven by a recirculating Marangoni-like tissue flow, providing insights into the tissue mechanics underlying embryonic development.
