  • Inhibition of the histone methyltransferase NSD2 and the androgen receptor in preclinical models can reverse lineage plasticity to suppress tumour growth and promote cell death in multiple subtypes of castration-resistant prostate cancer.

  • The authors present resonant inelastic x-ray scattering measurements of Sr2RuO4 in the normal Fermi-liquid state. They find that spin excitations are confined below 200 meV, while orbital fluctuations appear only at higher energies. This separation of energy scales is a hallmark of Hund’s-rule-induced electron correlations.

  • Recent theoretical studies indicate that the Kitaev model may be realized in framework materials exhibiting extended superexchange pathways. Here the authors report experimental evidence showing that the material requirements for a Kitaev quantum spin liquid are satisfied in a inorganic framework material.

  • RuCl3 has stood out as a prime candidate in the search for quantum spin liquids; however, its antiferromagnetic ordering at low temperature suggests deviations from typical QSL models. Here, using resonant inelastic x-ray scattering, the authors provide a comprehensive determination of the low energy effective Hamiltonian.

  • Squeezed states of light have been experimentally demonstrated to improve the performance of the Laser Interferometer Gravitational-wave Observatory (LIGO) in astrophysically relevant frequency regions. This enhanced performance may help to reach the sensitivity required for detecting gravitational waves.

  • The astronomical event GW170817, detected in gravitational and electromagnetic waves, is used to determine the expansion rate of the Universe, which is consistent with and independent of existing measurements.

  • ‘Squeezed light’ enables quantum noise in one aspect of light to be reduced by increasing the noise, or more accurately the quantum uncertainty, of a complementary aspect. This has now been used to push the detectors at the heart of the GEO600 gravitational wave observatory to unprecedented levels of sensitivity.

  • A stochastic background of gravitational waves is expected to arise from a superposition of a large number of unresolved gravitational-wave sources and should carry unique signatures from the earliest epochs of the Universe. Limits on the amplitude of the stochastic gravitational-wave background are now reported using the data from a two-year science run of the Laser Interferometer Gravitational-wave Observatory. These limits rule out certain models of early Universe evolution.
