Latest Chlorophyll Stories
Photosynthesis is a remarkable biological process that supports life on earth. Plants and photosynthetic microbes do so by harvesting light to produce their food, and in the process, also provide vital oxygen for animals and people.
An international team of scientists has determined the structure of the chlorophyll molecules in green bacteria that are responsible for harvesting light energy.
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,...
Researchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis.
In pursuing cleaner energy there is such a thing as being too green.
In a study of the molecular mechanisms by which plants protect themselves from oxidation damage should they absorb too much sunlight during photosynthesis, a team of researchers has discovered a molecular â€œdimmer switchâ€ that helps control the flow of solar energy moving through the system of light harvesting proteins. This discovery holds important implications for the future design of artificial photosynthesis systems that could provide the world with a sustainable and secure...
Imagine a technology that would not only provide a green and renewable source of electrical energy, but could also help scrub the atmosphere of excessive carbon dioxide resulting from the burning of fossil fuels. Thatâ€™s the promise of artificial versions of photosynthesis, the process by which green plants have been converting solar energy into electrochemical energy for millions of years. To get there, however, scientists need a far better understanding of how nature does it, starting...
Sargassum seaweed, famous in nautical lore for entangling ships in its dense floating vegetation, has been detected from space for the first time thanks to an instrument aboard ESAâ€™s environmental satellite, Envisat. The ability to monitor Sargassum globally will allow researchers to understand better the primary productivity of the ocean and better predict climate change.
Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry â€“ an advance that may ultimately help shed light on the ecology of the world's oceans.
Autumn's joyous pageant of red, yellow and gold relies on a single protein, new research reveals.
