IRVINE, Calif., July 13, 2011 /PRNewswire/ -- ChromaDex Corp. (OTCBB.:CDXC) today announced that Cornell University has granted the natural products company ChromaDex exclusive worldwide rights to a novel manufacturing process for nicotinamide riboside (NR). "Despite its potential to deliver significant health benefits, nicotinamide riboside, or NR, is currently not available to the market as a dietary ingredient," said Frank L. Jaksch, Jr., CEO of ChromaDex. "The technology we have...

How deep is the ocean's capacity to buffer against climate change? As one of the planet's largest single carbon absorbers, the ocean takes up roughly one-third of all human carbon emissions, reducing atmospheric carbon dioxide and its associated global changes. But whether the ocean can continue mopping up human-produced carbon at the same rate is still up in the air. Previous studies on the topic have yielded conflicting results, says University of Wisconsin-Madison assistant professor Galen...

By Stuart Wolpert, UCLA The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA life scientists goes a long way toward solving it. In research federally funded by the National Science Foundation, the biologists found that smaller leaves are structurally and physiologically better adapted to dry soil because of their distinct vein systems. The research will be...

Knowledge could improve microorganism as a renewable energy source A new computer model of blue-green algae can predict which of the organism's genes are central to capturing energy from sunlight and other critical processes. Described in a paper published in the journal Molecular BioSystems, the model could advance efforts to produce biofuel and other energy sources from blue-green algae, known as cyanobacteria. Researchers from the Department of Energy's Pacific Northwest National...

The world's oceans support vast populations of single-celled organisms (phytoplankton) that are responsible, through photosynthesis, for removing about half of the carbon dioxide that is produced by burning fossil fuels "“ as much as the rainforests and all other terrestrial systems combined. One group of phytoplankton, known as the coccolithophores, are known for their remarkable ability to build chalk (calcium carbonate) scales inside their cells, which are secreted to form a...

Although scientists have been able to sequence the genomes of many organisms, they still lack a context for associating the proteins encoded in genes with specific biological processes. To better understand the genetics underlying plant physiology and ecology"”especially in regard to photosynthesis"”a team of researchers including Carnegie's Arthur Grossman identified a list of proteins encoded in the genomes of plants and green algae, but not in the genomes of organisms that...

Controlling water loss is an important ability for modern land plants as it helps them thrive in changing environments. New research from the University of Bristol, published today in the journal Current Biology, shows that water conserving innovations occurred very early in plants' evolutionary history. The research focused on the role of stomata, microscopic pores in the surface of leaves that allow carbon dioxide gas to be taken up for use in photosynthesis, while at the same time allowing...

Scientists from NASA's Goddard Space Flight Center in Greenbelt, Md., have produced groundbreaking global maps of land plant fluorescence, a difficult-to-detect reddish glow that leaves emit as a byproduct of photosynthesis. While researchers have previously mapped how ocean-dwelling phytoplankton fluoresce, the new maps are the first to focus on land vegetation and to cover the entire globe. To date, most satellite-derived information related to the health of vegetation has come from...

Photosynthesis mechanics is the answer to solar energy Understanding the way plants use and store light to produce energy could be the key ingredient in the fight against climate change, a scientist at Queen Mary, University of London says. Professor Alexander Ruban from Queen Mary's School of Biological and Chemical Sciences has been studying the mechanisms behind photosynthesis, a process where plants use sunlight and carbon dioxide to produce food and release oxygen, for 30 years. In a...

A NASA-led research team has used a variety of NASA satellite data to create the most precise map ever produced depicting the amount and location of carbon stored in Earth's tropical forests. The data are expected to provide a baseline for ongoing carbon monitoring and research and serve as a useful resource for managing the greenhouse gas carbon dioxide. The new map, created from ground- and space-based data, shows, for the first time, the distribution of carbon stored in forests across more...
