  • Dual-scale chemical ordering in CoNiV-based alloys improves the synergy of strength and ductility at cryogenic temperatures, providing an approach for obtaining high-performance metallic materials for cryogenic applications.

  • Coherent conversion between optical and microwave photonics is needed for future quantum applications. Here, the authors combine thin-film lithium niobate and superconductor platforms as a hybrid electro-optic system to achieve high-efficiency frequency conversion between microwave and optical modes.

  • Single photon devices are needed for many future technologies, but resolving the color of single photons in a compact architecture is still a challenge. The authors present a broadband, chip-scale spectrometer for measuring single photon wavelengths from 600 to 2000 nm with no moving parts.

  • Up to 100 photons are resolved by a waveguide-integrated and hybrid spatiotemporal-multiplexed superconducting nanowire single-photon detector array. Using this detector array, photon statistical behaviour for a true thermal and a coherent light source is verified.

  • Superconducting electro-optic modulators for a cryogenic-to-room-temperature link are demonstrated. The record-low half-wave voltage of 42 mV is achieved on a 1-m-long modulator. By matching the velocity of microwave and optical signals, a 0.2-m-long modulator can achieve a 3 dB bandwidth of over 17 GHz.

  • A population of freezing white dwarf stars maintaining a constant luminosity for a duration comparable with the age of the universe can be explained by a solid–liquid distillation mechanism interrupting cooling for billions of years.

  • Recent work has demonstrated the potential of polycrystalIine antiferromagnetic materials for spintronics. Here the authors report evidence of magnetic phase transitions in a polycrystalline non-collinear antiferromagnet, which are explained by a phenomenological model with topological orbital momenta.

  • An analysis of the relation between a star’s initial mass and its final mass (as a white dwarf) reveals a kink in the initial mass range 1.65–2.10 M⊙. This kink appears to correspond to the minimum mass required for carbon star formation in the Milky Way at solar metallicity.

  • Hybrid quantum systems would allow interfacing superconducting nodes with optical links. Here, the authors demonstrate an integrated platform where 10 GHz phonons are resonantly coupled with photons in a superconducting cavity and a nanophotonic cavity at the same time, allowing efficient mediation of bidirectional microwave-optical conversion.

  • Obesity changes the characteristics of the immune response induced in a mouse model of atopic dermatitis, suggesting therapies that could be used against immune dysregulation in obesity.

  • Fat-resident regulatory T cells (fTreg cells) accumulate in adipose tissue of mice as a function of age, but not obesity; mice without fTreg cells are protected against age-associated insulin resistance, but remain susceptible to obesity-associated insulin resistance and metabolic disease, indicating different aetiologies of age-associated versus obesity-associated insulin resistance.
