...graduate student at the California Institute of Technology, believes it's possible, based on her recent experiments with jellyfish blooms in a freshwater lake in Palau. Using high-powered underwater lasers and video cameras, Katija and her team studied how the movement of jellyfish impacts the water around them. Researchers placed a fluorescent dye in front of the jellyfish and observed what happened as the jellyfish swam through it. To their surprise, rather than swimming through the dye, the jellyfish appeared to pick it up, tucking it in a space just behind their tentacles. As the jellyfish swam, they carried...
...research, published in the journal Nature, would suggest that the mass movement of marine animals - even tiny zooplankton like krill - may play a significant role in churning the ocean. It may help mix cooler water with warm, and disperse salts, nutrients and pollutants across the various layers of the ocean, which is critical to the strength of ocean currents and the health of the marine ecosystems. Although ocean-mixing is largely attributed to winds and ocean tides, scientists say those factors cannot account for all the energy required to power, for example, the complete circulation of cold and warm water...
...oceanographers familiar with the subject say research into ocean-mixing is only just beginning and that it's too early to make such assertions. "I appreciate what they [the Caltech team] are saying, but taking experiments of one particular event and extrapolating it to a global scale is always problematic," says oceanographer Andre Visser of the Technical University of Denmark...
...independence from political meddling. "If you look at what she's done since taking her job, you realize Anne Lauvergeon had the drive, creativity and vision to assemble all these parts into a single unit to be ready for a nuclear renaissance that she saw coming," says Ben Elias, research analyst for Sterne, Agee & Leach in New York. "There are very few CEOs in her league...
...charging stations. The effort isn't limited to Japan: Nissan has formed 27 partnerships around the world to clear the way for EVs. "They know people are going to need [an electric-vehicle ecosystem] and it's got to be part of the package," says Chris Richter, senior research analyst for CLSA, a Hong Kong-based brokerage. "Nissan is pulling together the whole package of subsidies, charging, recycling of batteries - the whole kit." (See the 12 most important cars of all time...
