<jats:title>Abstract</jats:title><jats:p>The sensing of gravity has emerged as a tool in geophysics applications such as engineering and climate research<jats:sup>1–3</jats:sup>, including the monitoring of temporal variations in aquifers<jats:sup>4</jats:sup> and geodesy<jats:sup>5</jats:sup>. However, it is impractical to use gravity cartography to resolve metre-scale underground features because of the long measurement times needed for the removal of vibrational noise<jats:sup>6</jats:sup>. Here we overcome this limitation by realizing a practical quantum gravity gradient sensor. Our design suppresses the effects of micro-seismic and laser noise, thermal and magnetic field variations, and instrument tilt. The instrument achieves a statistical uncertainty of 20 E (1 E = 10<jats:sup>−9</jats:sup> s<jats:sup>−2</jats:sup>) and is used to perform a 0.5-metre-spatial-resolution survey across an 8.5-metre-long line, detecting a 2-metre tunnel with a signal-to-noise ratio of 8. Using a Bayesian inference method, we determine the centre to ±0.19 metres horizontally and the centre depth as (1.89 −0.59/+2.3) metres. The removal of vibrational noise enables improvements in instrument performance to directly translate into reduced measurement time in mapping. The sensor parameters are compatible with applications in mapping aquifers and evaluating impacts on the water table<jats:sup>7</jats:sup>, archaeology<jats:sup>8–11</jats:sup>, determination of soil properties<jats:sup>12</jats:sup> and water content<jats:sup>13</jats:sup>, and reducing the risk of unforeseen ground conditions in the construction of critical energy, transport and utilities infrastructure<jats:sup>14</jats:sup>, providing a new window into the underground.</jats:p>

<jats:title>Abstract</jats:title><jats:p>The lattice symmetry of a crystal is one of the most important factors in determining its physical properties. Particularly, low-symmetry crystals offer powerful opportunities to control light propagation, polarization and phase<jats:sup>1–4</jats:sup>. Materials featuring extreme optical anisotropy can support a hyperbolic response, enabling coupled light–matter interactions, also known as polaritons, with highly directional propagation and compression of light to deeply sub-wavelength scales<jats:sup>5</jats:sup>. Here we show that monoclinic crystals can support hyperbolic shear polaritons, a new polariton class arising in the mid-infrared to far-infrared due to shear phenomena in the dielectric response. This feature emerges in materials in which the dielectric tensor cannot be diagonalized, that is, in low-symmetry monoclinic and triclinic crystals in which several oscillators with non-orthogonal relative orientations contribute to the optical response<jats:sup>6,7</jats:sup>. Hyperbolic shear polaritons complement previous observations of hyperbolic phonon polaritons in orthorhombic<jats:sup>1,3,4</jats:sup> and hexagonal<jats:sup>8,9</jats:sup> crystal systems, unveiling new features, such as the continuous evolution of their propagation direction with frequency, tilted wavefronts and asymmetric responses. The interplay between diagonal loss and off-diagonal shear phenomena in the dielectric response of these materials has implications for new forms of non-Hermitian and topological photonic states. We anticipate that our results will motivate new directions for polariton physics in low-symmetry materials, which include geological minerals<jats:sup>10</jats:sup>, many common oxides<jats:sup>11</jats:sup> and organic crystals<jats:sup>12</jats:sup>, greatly expanding the material base and extending design opportunities for compact photonic devices.</jats:p>

<jats:title>Abstract</jats:title><jats:p>The mutational landscape is shaped by many processes. Genic regions are vulnerable to mutation but are preferentially protected by transcription-coupled repair<jats:sup>1</jats:sup>. In microorganisms, transcription has been demonstrated to be mutagenic<jats:sup>2,3</jats:sup>; however, the impact of transcription-associated mutagenesis remains to be established in higher eukaryotes<jats:sup>4</jats:sup>. Here we show that ID4—a cancer insertion–deletion (indel) mutation signature of unknown aetiology<jats:sup>5</jats:sup> characterized by short (2 to 5 base pair) deletions —is due to a transcription-associated mutagenesis process. We demonstrate that defective ribonucleotide excision repair in mammals is associated with the ID4 signature, with mutations occurring at a TNT sequence motif, implicating topoisomerase 1 (TOP1) activity at sites of genome-embedded ribonucleotides as a mechanistic basis. Such TOP1-mediated deletions occur somatically in cancer, and the ID-TOP1 signature is also found in physiological settings, contributing to genic de novo indel mutations in the germline. Thus, although topoisomerases protect against genome instability by relieving topological stress<jats:sup>6</jats:sup>, their activity may also be an important source of mutations in the human genome.</jats:p>
