“The Southern Ocean is a large window by which the atmosphere connects to the interior of the ocean below. Until now we didn’t know exactly the physical processes of how carbon ends up being stored deep in the ocean. It’s the combination of winds, currents and eddies that create these carbon-capturing pathways drawing waters down into the deep ocean from the ocean surface,” said lead author Jean-Baptiste Sallée from British Antarctic Survey. “Now that we have an improved understanding of the mechanisms for carbon draw-down we are better placed to understand the effects of changing climate and future carbon absorption by the ocean.”The team noted that the Southern Ocean could allow scientists to better predict how ocean currents and ocean systems around the world deal with the increasingly large amount of carbon dioxide. Until now, climate scientists understood little about the relationship between oceanic systems and carbon dioxide. Due !
to the size and remote location of the Southern Ocean, scientists have only recently been able to explore the workings of the ocean with the help of the small robotic probes.<br />http://www.capitolcolumn.com/news/new-co2-findings-may-unlock-secrets-of-global-warming-video/

How summer thunderstorms could be punching new holes in the ozone layer - Christian Science Monitor
In fact, Anderson's team initially was working on another climate problem: the formation of cirrus clouds and their effect on climate. Clouds represent one of the big areas of uncertainty in climate models. And cirrus clouds can have a warming effect on climate by allowing sunlight through but trapping heat rising up from underneath. The tops of thunderheads are one source of cirrus clouds, which assume their feather-like appearance as high-altitude winds blow across the tops of the thunderheads, giving them their anvil shape.The study points to "the potential for a pretty significant effect on stratospheric ozone at latitudes where we normally wouldn't think that would happen," said Mario Molina, an atmospheric scientist at the University of California at San Diego who shared the Nobel Prize in Chemistry in 1995 with the late Frank Rowland. The two worked out the chemistry behind stratospheric ozone depletion and chlorofluorocarbons, once widely used as refrigeran!

Stanford Researchers Complete 1st Complete Computer Model of an Organism - CleanTechnica
“This achievement demonstrates a transforming approach to answering questions about fundamental biological processes,” said James M. Anderson, director of the National Institutes of Health Division of Program Coordination, Planning and Strategic Initiatives. “Comprehensive computer models of entire cells have the potential to advance our understanding of cellular function and, ultimately, to inform new approaches for the diagnosis and treatment of disease.”Cells that took longer to begin DNA replication had time to amass a large pool of free nucleotides. The actual replication step, which uses these nucleotides to form new DNA strands, then passed relatively quickly. Cells that went through the initial step quicker, on the other hand, had no nucleotide surplus. Replication ended up slowing to the rate of nucleotide production.<br />http://cleantechnica.com/2012/07/22/stanford-researchers-complete-1st-complete-computer-model-of-an-organism/

Institutional Mission and University
University administration should generate a pool of creative ideas for faculty members. When designing an academic research project, professors know the general preferences of a university, but not necessarily specific policy of their own university.

University as a Country
The structure of a university is very similar to a country, and its management system too; a smaller society but utopia, due to its sophisticated community. Factors like national benefits, patriotism, and nostalgia are all (and must be) the case in a smaller scale. Even outsiders (usually in administrative roles) are expected to behave like loyal alumni, learn the school alma mater, and become interested in in the major sport teams, and other traditional functions of the university. This practical allegory is to utilize available models. The athletic success in Olympic is of political important (not just fun) for a country, it is the same for a university fame (for attracting students). The reasons and motivations of students for attending a university are like those of immigration. Thus, university leadership should empower its own country through united national strategies. This is the reason that todayĆ¢€™s university essential needs to implement change. The ratio of people living in developed country to those living in developing countries from one to two (in 1995) is approaching one to four (in 2010)
