Google Earth Application Maps Carbon's Course
ScienceDaily (2009-09-30) -- Sometimes a picture really is worth a thousand words, particularly when the picture is used to illustrate science. Technology is giving us better pictures every day, and one of them is helping a NASA-funded scientist and her team to explain the behavior of a greenhouse gas. Google Earth -- the digital globe on which computer users can fly around the planet and zoom in on key features -- is attracting attention in scientific communities and aiding public communication about carbon dioxide. Recently Google held a contest to present scientific results using KML, a data format used by Google Earth.

Chemical In Red Wine, Fruits And Vegetables Counters Unhealthy Effects Of High-fat Foods
ScienceDaily (2008-01-06) -- Just as additives help gasoline burn cleaner, a research report shows that the food industry could take a similar approach toward reducing health risks associated with fatty foods. These "meal additives" would be based on work of researchers who discovered that consuming polyphenols (natural compounds in red wine, fruits, and vegetables) simultaneously with high-fat foods may reduce health risks associated with these foods.

That Late-night Snack: Worse Than You Think

A study has found that eating at irregular times -- the equivalent of the middle of the night for humans, when the body wants to sleep -- influences weight gain. This is the first causal evidence linking meal timing and increased weight gain.
