  • The first sample of farside lunar soil, collected by Chang’e-6, is strongly cohesive. The high cohesion stems from its fine particle size with intricate shape, probably a result of the high plagioclase abundance and intense meteorite impacts at the sampling site.

  • Evolution of slow slip to dynamic rupture on seabed megathrusts in basalt can be explained by strain localization and a transition to strain weakening behaviour encoded as a microtextural signature in triaxial shear experiments on oceanic basalt gouge.

  • Recently triggered seismic events such as the Pohang earthquake have exceeded predictions of average energy releases by a factor of 1000. A new framework is proposed to define maximum event magnitudes as a function of pre-existing critical stresses and fluid injection volume.

  • Red giants are evolved stars that have exhausted the supply of hydrogen in their cores and instead burn hydrogen in a surrounding shell. Once a red giant is sufficiently evolved, the helium in the core also undergoes fusion. However, it is difficult to distinguish between the two groups. Asteroseismology offers a way forward. This study reports observations of gravity-mode period spacings in red giants using high precision photometry obtained by the Kepler spacecraft. It is found that the stars fall into two clear groups, making it possible to distinguish unambiguously between hydrogen-shell-burning stars and those that are also burning helium.

  • Earthquake rupture speeds significantly impact seismic hazards. Here, authors report laboratory earthquake experiments reproducing early and stable subEshelby supershear ruptures, and unlocking the correlation between rupture speed and driving load.

  • Thirty years of geothermal heat production at Coso in California depleted shear stresses within the geothermal reservoir, which changed its faulting style and inhibited aftershocks from the 2019 Ridgecrest earthquake.

  • Factors such as fault mineralogy, roughness, temperature, geological settings, and fluid injection strategies influence seismicity-permeability coupling behavior of faults, with fault gouge controlling interactions in mature faults and rough surfaces governing them in incipient faults, according to a synthesis of theoretical, experimental, and numerical studies.

  • Bright star \(\nu\) Indi shows elevated levels of alpha-process elements, suggesting great age, and is kinematically heated, probably from the merger of a dwarf galaxy with the Milky Way. Chaplin et al. make a case for \(\nu\) Indi being an accurate indicator of the timing for the Gaia–Enceladus merger.
