Peter M. Ray, a biologist known for his scientific work and his passion for winemaking, has died at the age of 94. Stanford's School of Humanities and Sciences announced his death, honoring a long career in biology that spanned decades. Colleagues remember him both for his contributions to science and his life outside the lab.

Santa Clara University's College of Arts and Sciences has published a story profiling student research on X-rays. The piece showcases undergraduate or graduate work in physics carried out at the California university. Beyond the feature itself, no further details about the project, the students involved, or its findings are available.

Researchers have used in situ grazing-incidence wide-angle X-ray scattering to show how Prussian blue regulates perovskite nucleation and phase transformation dynamics. The findings clarify how the additive guides crystal formation during perovskite film growth, a process central to improving the efficiency and stability of perovskite solar cells and optoelectronic devices.
