  • It is experimentally challenging to observe an intermediate liquid in solid–solid phase transitions due to short lifetimes of the resulting metastable states. Here, Linet al. show that a metastable bismuth liquid can be formed from a crystalline solid through decompression and maintained for hours.

  • Lithium metal under extreme pressures shows a sequence of structural phase transitions. Here, the authors use neutron scattering and X-ray diffraction techniques under high pressure to expand the experimental phase diagram of lithium, showing an unexpected deviation from existing boundaries.

  • A tour-de-force study finds that as the pressure of lithium is increased to 50 GPa, its melting point drops to 190 K—the lowest yet observed of any elemental metal. The results suggest lithium could be a promising candidate for exploring exotic states of matter similar to that predicted for metallic hydrogen.

  • X-ray diffraction measurements of solid hydrogen provide crystallographic information for high-pressure phases of hydrogen and transitions between them, suggesting a series of isostructural transitions under compression before band closure and metallization.
