Enhancing the efficiency of light-induced phase transitions through transient local distortions
Nature Physics, Published online: 17 May 2024; doi:10.1038/s41567-024-02475-3
Ultrafast light pulses, if they are sufficiently intense, can induce phase transitions on ultrafast timescales. It is now shown that when a system is first excited by a weak preparatory pulse, this generates local changes in structure that transiently lower the energy barrier to the phase transition, enabling high-speed and energy-efficient transitions.Cold and ultracold molecules

Nature Physics, Published online: 16 May 2024; doi:10.1038/s41567-024-02528-7
Social activities are common in many research groups, often based around outdoor activities such as hiking. We argue that there are more inclusive ways to bring a team together.Metrology for a sustainable future
Nature Physics, Published online: 16 May 2024; doi:10.1038/s41567-024-02503-2
UNESCO has now formally adopted World Metrology Day as a UNESCO International Day to be observed on 20 May each year — the theme of 2024 is sustainability. Shanay Rab and Richard Brown take a look at its origin.Quantum sensing and metrology for fundamental physics with molecules
Nature Physics, Published online: 16 May 2024; doi:10.1038/s41567-024-02499-9
Ultracold atoms are a well-established platform for quantum sensing and metrology. This Review discusses the enhanced sensing capabilities that molecules offer for a range of phenomena, including symmetry-violating forces and dark matter detection.How Iranian students can master integration into German academia
Nature Physics, Published online: 15 May 2024; doi:10.1038/s41567-024-02490-4
Thousands of Iranians study at German universities every year, but many struggle with the German academic system. Here, we offer some advice.Experience under the spotlight

Nature Physics, Published online: 15 May 2024; doi:10.1038/s41567-024-02504-1
Active cell contraction drives hole nucleation, fracture and crack propagation in a tissue monolayer through a process reminiscent of dewetting thin films.Quantum spherical codes
Nature Physics, Published online: 15 May 2024; doi:10.1038/s41567-024-02496-y
Many recent experiments have stored quantum information in bosonic modes, such as photons in resonators or optical fibres. Now an adaptation of the classical spherical codes provides a framework for designing quantum error correcting codes for these platforms.Across dimensions
Nature Physics, Published online: 13 May 2024; doi:10.1038/s41567-024-02492-2
The properties of quantum matter arise from the combined effects of dimensionality, interactions and quantum statistics. An experiment now studies what happens to ultracold bosons when the dimensionality of the system changes continuously between one and two dimensions.Bacteria spiral into control
Nature Physics, Published online: 13 May 2024; doi:10.1038/s41567-024-02509-w
Spiral waves of cell density can form and propagate through bacterial biofilms. These waves are formed by a self-organization process that coordinates pulling forces between neighbouring cells.Elastic response reveals the pairing symmetry
Nature Physics, Published online: 13 May 2024; doi:10.1038/s41567-024-02508-x
The determination of the order parameter symmetry is a critical issue in the study of unconventional superconductors. Ultrasound measurements on UTe2, a candidate spin-triplet superconductor, now provide evidence for the single-component nature of its order parameter.Structural anisotropy results in mechano-directional transport of proteins across nuclear pores
Nature Physics, Published online: 13 May 2024; doi:10.1038/s41567-024-02438-8
Protein transport across the nuclear membrane is regulated by the nuclear pore complex. Experiments now show that the rates of nuclear transport rely on the presence of locally mechanically soft regions of the transported proteins.Laser-driven high-energy proton beams from cascaded acceleration regimes

Laser-driven proton acceleration experiments achieve energies of up to 150 MeV with particle yields that are relevant for applications such as radiobiology.Polarity-driven three-dimensional spontaneous rotation of a cell doublet
Nature Physics, Published online: 13 May 2024; doi:10.1038/s41567-024-02460-w
Cells can form a rotating doublet. This rotation is driven by the symmetry breaking of myosin polarization in the cortices of the two cells.Mechanical asymmetry in nucleocytoplasmic protein transport
Nature Physics, Published online: 10 May 2024; doi:10.1038/s41567-024-02452-w
The nuclear pore complex of eukaryotic cells senses the mechanical directionality of translocating proteins, favouring the passage of those that have a leading mechanically labile region. Adding an unstructured, mechanically weak peptide tag to a translocating protein increases its rate of nuclear import and accumulation, suggesting a biotechnological strategy to enhance the delivery of molecular cargos into the cell nucleus.
