Fructose -- Found In High-fructose Corn Syrup, Sugar -- Sets Table For Weight Gain Without Warning

Table sugar and high-fructose corn syrup are about 50% fructose and these ingredients have become increasingly common in many foods and beverages. Eating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats. This is the first study to show that leptin resistance can develop as a result of high fructose consumption and that leptin resistance can develop silently, that is, with little indication that it is happening.

Warming In Yosemite National Park Sends Small Mammals Packing To Higher, Cooler Elevations

UC Berkeley's resurvey of animal populations in California's eastern mountains kicked off in 2003 with a resurvey of Yosemite National Park, following the route of Joseph Grinnell in 1914-20. The first results show that small mammals have moved to higher elevations as a result of warming, some expanding their range upward, others moving upward and abandoning lower elevations entirely. Though biodiversity remains unchanged, the rapid rate of change sounds a cautionary note about global warming.
