Analysis of microfossils found in ocean sediment cores is illuminating the environmental conditions that prevailed at high latitudes during a critical period of Earth history.

Around 55 million years ago at the beginning of the Eocene epoch, the Earth's poles are believed to have been free of ice. But by the early Oligocene around 25 million years later, ice sheets covered Antarctica and continental ice had developed on Greenland.

In a pilot project that could help better manage the planet's strained natural resources, NASA satellites and sensors are providing a local Washington community the information needed to make more accurate river flow predictions on a daily basis, helping them manage their water availability .

"World leaders are struggling to protect natural resources for future generations," said Jeff Ward, a senior research scientist at the Department of Energy's Pacific Northwest National Laboratory. "These tools help us sustainably use natural resources while balancing environmental, cultural and economic concerns."

NASA researchers studying urban landscapes say the intensity of the "heat island" created by a city depends on the ecosystem it replaced and on the regional climate where the city is located. Urban areas developed in arid and semi-arid regions show far less heating compared with the surrounding countryside than cities built amid forested and temperate climates.

Before the tobacco industry gave up the fight over the health effects of smoking, it was common for major cigarette manufacturers like Phillip Morris to fight advertising restrictions on their product in every possible way--even if that meant designing softball regulations that didn't regulate anything. Now researchers are reporting that alcohol manufacturers in Sub-Saharan Africa are following big tobacco's lead.

Even though the FDA doesn't actually know how many underage smokers choose flavored cigarettes, a new study claims that thrill-seeking teenagers are especially susceptible to fruit-flavored cigarettes and the federal government was right to outlaw the flavorful smokes last September.

"We found that those teens who gravitate toward novel experiences were especially drawn to cigarettes described as having an appealing, sweet flavor, such as cherry," says lead author Kenneth Manning with Colorado State University.

Your ability to resist that tempting cookie depends on how a big a threat you perceive it to be, according to a study in the Journal of Consumer Research.

University of Texas researchers studied techniques that enable us to resist food and other temptations. "Four experiments show that when consumers encounter temptations that conflict with their long-term goals, one self-control mechanism is to exaggerate the negativity of the temptation as a way to resist, a process we call counteractive construal," the researchers write.
