The findings of the international research team […]

Credit: Greg Stewart/SLAC National Accelerator Laboratory One of nature’s most important chemical reactions is now being captured in a breakthrough “molecular movie.” Using a unique combination of nanoscale imaging and chemical analysis, an international team of researchers has revealed a key step in the molecular mechanism behind the water splitting […]

Understanding nature’s process could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water. Photosystem II is a protein complex in plants, algae and cyanobacteria that is responsible for splitting water and producing the oxygen we breathe. Over the past few years, […]

Assistant Professor Gabriela Schlau-Cohen has observed, for the first time, a mechanism that plants use to protect themselves from sun damage. Credit: Jose-Luis Olivares Study reveals a mechanism that plants can use to dissipate excess sunlight as heat. For plants, sunlight can be a double-edged sword. They need it to […]

An electron microscope image shows the semiconductor nanowires. These deliver electrons to metal nanoparticles, which turn carbon dioxide and water into methane. Credit: Baowen Zhou A new artificial photosynthesis approach uses sunlight to turn carbon dioxide into methane, which could help make natural-gas-powered devices carbon neutral. Methane is the main […]
