- The key for interstellar travel might be light
- Blowin’ in the windNature Physics, Published online: 11 April 2025; doi:10.1038/s41567-025-02850-8 In addition to photovoltaics, wind turbines are among the most powerful renewable energy sources. Thorsten Schrader and Frank Härtig outline the challenges for metrology.
- Underrepresentation of women last authors in <i>Nature Physics</i>Nature Physics, Published online: 11 April 2025; doi:10.1038/s41567-025-02857-1 Last-author papers are vital to the career advancement of researchers in many physics subfields. We present data on the underrepresentation of women as last authors in Nature Physics and discuss the implications.
- Continuous recoil-driven lasing and cavity frequency pinning with laser-cooled atomsNature 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.
- Topological dynamics of rapid non-planar gaits in slithering snakesNature 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.
- Resourceful dissipationNature 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.
- Bacterial second messengers achieve extraordinary signal capacityNature 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.
- Concurrent spin squeezing and field tracking with machine learningNature 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.
