Researchers Watch Photosynthesis Catalyst In Action
2013-02-15 16:11:08

Lee Rannals for redOrbit.com - Your Universe Online Researchers at Stanford University and the Department of Energy's (DOE) SLAC National Accelerator Laboratory used an X-ray laser to get a glimpse of photosynthesis in action. Using the laser, they were able to look at the structure and chemical behavior of a natural catalyst involved in photosynthesis. "This method opens up the way to study changes going on in the catalytic cycle of the water oxidation in nature," Junko Yano, a chemist...

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. In a study published today in Angewandte Chemie, Monash University and CSIRO scientists for the first time discovered a photosensitive metal organic framework (MOF) - a class of materials known for their exceptional capacity to store gases. This has created a powerful and cost-effective new tool to...

Tree Death In Amazon Much Higher Than Previously Believed
2013-01-29 12:28:36

Alan McStravick for redOrbit.com - Your Universe Online If a tree falls in the forest and no one is around, does it have a direct impact on climate change? A new study from the Lawrence Berkeley National Laboratory (Berkeley Lab) set out to answer this question. Forests are critical to the equilibrium of Earth´s climate since they absorb large quantities of the greenhouse gas carbon dioxide directly from our atmosphere. The death of a tree, however, reverses the flow of carbon and...

Chemists at the University of California, Davis, have engineered blue-green algae to grow chemical precursors for fuels and plastics -- the first step in replacing fossil fuels as raw materials for the chemical industry. "Most chemical feedstocks come from petroleum and natural gas, and we need other sources," said Shota Atsumi, assistant professor of chemistry at UC Davis and lead author on the study published Jan. 7 in the Proceedings of the National Academy of Sciences. The U.S....

Photosynthesis - The Last Link In The Chain
2013-01-05 05:45:05

April Flowers for redOrbit.com - Your Universe Online 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 (LMU) has found the missing link, which turns out to be not so new. All life on Earth is sustained by photosynthesis, a sunlight powered process that provides energy-rich compounds and the molecular oxygen that higher organisms depend...

The Evolution Of Grass Photosynthesis
2012-12-26 05:22:06

Brett Smith for redOrbit.com - Your Universe Online In examining the differences in photosynthetic activity among certain types of grasses, researchers from Brown University found that some plants are positioned to take evolutionary advantage of certain situations. According to a report in the Proceedings of the National Academy of Sciences, Brown researcher Pascal-Antoine Christin spent two years analyzing the cellular anatomy of 157 living species of two different grass clades, BEP...

Women with higher circulating carotenoid levels are at a reduced risk of breast cancer according to a study published December 6 in the Journal of the National Cancer Institute Carotenoids, which are micronutrients found in fruits and vegetables, have been found to have anticarcinogenic properties. Previous experimental studies have shown that carotenoids inhibit the tumor progression and reduce proliferation of estrogen receptor—positive (ER+) and estrogen receptor—negative...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
