Stories about: photosynthesis |

Common scientific knowledge has it that, about 2.4 billion years ago, the levels of the chemical oxygen in the Earth's atmosphere began to suddenly climb, until they reached at one point concentrations similar to the ones existent today. The fact that the planet is able to support such a variety of life forms is... |

The US Department of Energy (DOE) has recently announced that it will award $1.7 million in grant money to the University of Rochester, to support new, alternative, hydrogen-production methods. The university's approach relies on using artificial photosynthesis and carbon nanotubes to get the job done, and this ... |

Photosynthesis is, undoubtedly, the most important process on Earth, and is also the main source of oxygen for animals and humans. It occurs when the vegetation harvests carbon dioxide and sunlight from the atmosphere, and releases oxygen back, while at the same time generating energy for itself. Directly responsible... |

The process of photosynthesis is perhaps the most important one on Earth, as it is the source of our oxygen, and also a huge storage facility for atmospheric carbon dioxide, of which we pump copious amounts in the atmosphere. But one of the bases for this process is the vegetation's ability to capture and conver... |

With more than 300 exoplanets discovered thus far and hundreds others to be found soon by the Kepler Space Telescope, astronomers are now considering methods of investigating their surface, in a bid to discover signs of life. Naturally, sending probes to these worlds is unfeasible, on account of the fact that some of... |

The goal of carbon cycle research is to find out exactly how much carbon is being trapped in plants and on ocean floors, so as to safely say how much carbon can be emitted at any given time. But such scientific endeavors have been fruitless until now, seeing how experts couldn't measure the exact quantities of t... |

According to new researches, life as we know it didn't start 2.7 billion years ago, as first speculated. The process that is fundamental to sustaining life on this planet actually started developing some 2.15 billion years ago, argue researchers at the California Institute of Technology in Pasadena, following a ... |

The tropical Atlantic Ocean could become a net carbon dioxide sink, say the results of a study which found that seasonal blooms of ocean plankton fertilized by the waters of the Amazon river absorb more carbon dioxide than previously estimated. The waters extending from the mouth of the Amazon into the Atlantic ocean... |

This is exactly what plants do during the photosynthesis: stealing the hydrogen of the water using light. Hydrogen would be a very clean fuel, and a recent Penn State research has made a step further towards this direction. "This is a proof-of-concept system that is very inefficient. But ultimately, catalytic systems... |

From the most impressive geysers in the world to muddy volcanoes and thermal spring, Yellowstone National Park is a natural marvel. The park's life is spectacular, but the biggest surprises do not come from the grizzly bears and bisons, but from the bacteria inhabiting the hot springs. Researchers have discovere... |

We, people, depend on light. Over 80 % of the information we get is visual. That's why during the night we employ artificial light when we do not sleep, in order to prolong our activity. The dark is associated by human beings with fear, uncertainty and even dread. It's a legacy from the monkey stage: as diu... |

"A brain sensitive to light" has got a new meaning. Researchers at Duke University Medical Center and the Howard Hughes Medical Institute have engineered a breed of mice whose brain olfactory cells respond to a light flash. They introduced into the cells a gene from green algae that enables them to detect light and... |

This is the engine of life on Earth: photosynthesis is the process by which plants and cyanobacteria retain sunlight energy into biochemical compounds with almost 100-percent efficiency. The energy transfer must occur almost instantaneously, so little energy amount is lost as heat, so the secret is in the speed of th... |

In the current international situation, when most of the world's oil resources are on the hands of all kind of fanatic regimes, finding an alternative and renewable solution for oil is of extreme importance. Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory focus on the pho... |

This is the process that fuels life on Earth: plants simply mix carbon dioxide from the air, water and sunlight to turn them into biomass and oxygen. Chemists would also like to be able to use CO2 as a carbon source just like in the photosynthesis for synthesizing organic reactions, but this is not as simple as it mi... |
