...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 between the earth's poles and equator. The authors of the Nature paper write that marine activity of the kind they describe may be a "significant contributor to ocean-mixing and nutrient transport."

...health officials are bracing for a resurgence of the new H1N1/09 flu virus this fall, when the influenza season kicks into high gear with the resurgence of cold weather. By October, the government hopes to have 120 million doses of vaccine ready to fight the new virus, which is currently spreading around the world in the first pandemic in more than 40 years. Already, H1N1 is hitting the southern hemisphere hard: Argentina has recorded more than 160 deaths from H1N1, second most after the U.S. That's because it's winter in the southern hemisphere, and flu infections tend...
...infections tend to go up in the cold winter months and level off in the summer? According to a study from researchers at Mount Sinai Medical School, the flu virus is more stable and able to stay airborne longer when the air is cold and dry. The Mount Sinai researchers, who tested guinea pigs, found that the spread of the virus was most prevalent when the temperature reached a chilly 41°F (5°C); infections slowly decline as the mercury rises, before stopping altogether at 86°F (30°C). (Tropical countries, where fairly constant, high temperatures...
...cold temperatures aren't the only reason for the fluctuations. Most of us spend less time in the sun during the winter, and that means we can end up vitamin D-deficient, leaving us vulnerable to any number of infections. And spending more time indoors can also put us in the line of infection for the flu, particularly if we share enclosed spaces with others. School is in session during the fall and winter in the northern hemisphere, and classrooms are excellent vectors of infection for all illnesses, including the flu. (Read "Think H1N1 Is Bad Now?

...talks about his nuclear program but only directly with the U.S., what will Obama say in response? Is it likely that the President will insist on a diplomatic arrangement that is entirely a product of the Bush Administration? The White House likes to think of itself as guided by cold-blooded realists - diplomats who keep their eyes strictly on U.S. interests. Three successive Administrations - Clinton, Bush and now Obama - have decided the only real goal that matters when it comes to North Korea is getting it to climb off the nuclear ledge. (Whether that, in fact, is a realistic goal...
