Latest Photosynthesis Stories
Scientists have uncovered one of nature's long-kept secrets--the true fate of charcoal in the world's soils.
A "garden variety" leaf is a broad, flat structure, but if the garden happens to be somewhere arid, it probably includes succulent plants with plump leaves full of precious water.
Pigments found in plants and purple bacteria employed to provide protection from sun damage do more than just that. Researchers from the University of Toronto and University of Glasgow have found that they also help to harvest light energy during photosynthesis.
Chemists at the California Institute of Technology (Caltech) and the Lawrence Berkeley National Laboratory believe they can now explain one of the remaining mysteries of photosynthesis, the chemical process by which plants convert sunlight into usable energy and generate the oxygen that we breathe.
Researchers on board the Integrated Ocean Drilling Program's research vessel JOIDES Resolution drilled a water depth of 1.5 miles and hundreds of feet of sediment into the oceanic crust off the west coast of North America. Scientists studying these returned samples have found the first direct evidence of life deep within these samples.
Researchers used an X-ray laser to catch a glimpse of photosynthesis in action. The new technique allowed them to observe the structure and chemical behavior of a natural catalyst involved in photosynthesis.
Emissions from coal power stations could be drastically reduced by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight.
