  • Current management of pre-eclampsia consists of controlling maternal hypertension, preventing seizures and delivering the fetus at term. To aid clinical management, efforts are underway to identify biomarkers that can predict pre-eclampsia as early as the first trimester. In this second part of their Review on pre-eclampsia, Chaiworapongsa and colleagues describe these efforts, as well as the current management strategies for these patients.

  • Double Asteroid Redirection Test (DART) mission impact on asteroid Dimophos resulted in an elliptical ejecta plume. Here, the authors show that this elliptical ejecta is due to the curvature of the asteroid and makes kinetic momentum transfer less efficient.

  • The 33 minute change in the orbital period of Dimorphos after the DART kinetic impact suggests that ejecta contributed a substantial amount of momentum to the asteroid compared with the DART spacecraft alone.

  • The impact of the DART spacecraft on the asteroid Dimorphos is reported and reconstructed, demonstrating that kinetic impactor technology is a viable technique to potentially defend Earth from asteroids.

  • The authors report on a determination of the momentum transferred to an asteroid by kinetic impact, showing that the DART kinetic impact was highly effective in deflecting the asteroid Dimorphos.

  • Fluids at the plate interface are sourced from the dehydrating slab mantle beneath the Shumagin Gap in Alaska, and contribute to regional seismic risk by influencing rupture propagation, according to magnetotelluric observations and electrical resistivity modelling.

  • A modelling study of the bilobate nucleus of comet 67P/Churyumov–Gerasimenko reveals that it has spun much faster in the past, but that its chaotically changing spin rate has so far prevented it from splitting; eventually the two lobes will separate, but they will be unable to escape each other and will ultimately merge again—a situation that seems to be common among cometary nuclei.
