The increase in the number of overweight Americans has led to a so called epidemic of type 2 diabetes that shows no signs of slowing. More than two-thirds of adults are now overweight or obese. About 11 percent of adults ─ 24 million people ─ have diabetes, and up to 95 percent of them have type 2 diabetes, according to the National Institutes of Health. Diabetes is a major cause of heart disease and stroke and the major cause of kidney failure, limb amputations and new-onset blindness.
According to a new report published in the November issue of the Archives of General Psychiatry, individuals who experience both adversity as children and traumatic events as adults are more
likely to develop post-traumatic stress disorder (PTSD) than those individuals who experience
only one of these kinds of incidents.
The report also found that the risk was greater for individuals with a particular genetic mutation that may influence the way the brain processes the neurotransmitter serotonin, affecting an individual's anxiety levels and changing the way neurons react to fearful stimuli.
Thanks to the recent outbreak of the H1N1 flu virus, most people now recognize the need to maintain good hygiene as a means to avoid sickness. And undoubtedly, frequent updates on death tolls, school closures and airport screenings from health officials and media figures also deserve some credit for the public's hyper vigilance in maintaining good hygiene--frequently washing hands, sneezing into shirt sleeves and so on.
While these behaviors can be good ways to prevent the spread of disease, is it possible that the current trend of hygiene awareness is overblown? Even to the point of turning people into germaphobes?
Most people would probably say they love shopping online. With the prices of online stores being so much cheaper than traditional retailers, what's not to love? According to recently released research, the increasing lack of product choices found online may be a good candidate.
A new study, published in Marketing Science, found that the traditional system of selling through retailers encourages longer – rather than shorter – product lines, which could dry up as manufacturers turn to direct sales online.
The reason is pretty simple. As more manufacturers go online and cut out the middle men and accompanying price increases, they tend to lose their incentive to diversify their products.
Back in 2005, when a massive 35-mile-long rift broke open in the Ethiopia desert some geologists controversially claimed that a new ocean was forming as two parts of the African continent pulled apart.
Currently, scientists from several countries have supposedly confirmed that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world's oceans, and the rift may likely be the beginning of a new sea.
Charles Darwin described a canid on the Falkland Islands, off the east coast of Argentina, but it has long been extinct. Darwin called it Canis antarcticus, placing it in the same genus as the domestic dog, wolf and coyote
Since then, biologists have also puzzled over the Falklands wolf's ancestry, with suggestions that they were related to domestic dogs, North American coyotes, or South American foxes. The wolves were the size of a coyote, but much stockier, with fur the color of a red fox. They had short muzzles, just like gray wolves, and thick, wooly fur.
