Join us for a special talk with Helen Quinn - a pioneering particle physicist and former Stanford professor - as she shares her journey through physics and discovery. Helen Quinn reflects on her experience as a woman foraging a path in physics and learn how she helped reshape our understanding of the universe.

Researchers hoped to clarify the boundaries between different types of superionic water – the hot, black ice believed to exist at the core of giant ice planets. Instead, they found multiple atomic stacking patterns coexisting in overlapping configurations never seen before in this phase of water.

In its early lifetime, Earth likely went through cycles of compression and decompression, buckling and eventually rebounding under the violent young solar system’s bombardment of asteroids and comets. Though we would never want to go back to this epoch, Zhang et al. have recreated similar conditions in a laboratory to help study our home’s history.

With a new method that could be extended to study Earth’s core and nuclear fusion, they identify and explain jumps in the electrical conductivity of aluminum under extreme conditions.

  Students from the HEDS division joined SLAC's Holiday Social, recreating the HEDS division in gingerbread form as part of a SLAC-wide competition. 

  Arianna Gleason, the deputy director of the HEDS division, was announced as a newly elected Fellow of the Mineralogical Society of America, in recognition of her outstanding contributions to the fields of mineralogy, crystallography, geochemistry, and petrology.

  PhD student Edna Rebeca Toro Garza won a prize for her poster "Observing the influence of atomic and nanoscale structure on the DC conductivity of warm dense matter" at the 9th Meeting of the Asia-Pacific Conference on Plasma Physics, hosted in Fukuoka, Japan.

The team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing nuclear fusion.
