Latest Light-dependent reactions Stories
For almost three decades, scientists have tried to identify a particular enzyme involved in regulating electron transport during photosynthesis. Now, a research team from Ludwig Maximilians Universitat has found the missing link, which turns out to be not so new.
A biomimetic antenna for gathering sunlight may one day transform solar-powered devices. Sometimes when people talk about solar energy, they tacitly assume that we’re stuck with some version of the silicon solar cell and its technical and cost limitations. Not so.
In a head-to-head battle of harvesting the sun's energy, solar cells beat plants.
"I have a slide that has a photo of a cornfield and a big photovoltaic array," says Robert Blankenship, a scientist who studies photosynthesis at Washington University in St. Louis.
A U.S.-led international team of scientists says it has determined the structure of chlorophyll molecules in green bacteria that harvest light energy. The researchers said their findings might one day be used to build artificial photosynthetic systems, such as those that convert solar energy to electrical energy. We found that the orientation of the chlorophyll molecules make green bacteria extremely efficient at harvesting light, said Pennsylvania State University Professor Donald Bryant,...
Chemists are several steps closer to teasing hydrogen fuel from water using man-made molecular devices that collect electrons and use them to split hydrogen from oxygen.
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
