Native Australian Fruits Bear Sweet Antioxidants
Twelve native Australian fruits that are exceptional sources of antioxidants have been identified. The fruits: Kakadu plum, Illawarra plum, Burdekin plum, Davidson?s plum, riberry, red and yellow finger limes, Tasmanian pepper, brush cherry, Cedar Bay cherry, muntries and Molucca raspberry; were compared with blueberries (cultivar Biloxi) ?a fruit renowned for its high antioxidant properties. Fat Deficiency Gene Also Spurs Obesity
A gene earlier found to underlie lipodystrophy--a disorder characterized by a severe deficiency of fat--can also spur obesity, according to new research published in the premier issue of Cell Metabolism. The gene, which alters fat storage and metabolism, is the first found to adjust body fat content up or down, depending on its expression level in fat and muscle, according to the researchers. Scientists, Cooperators Identify Potato Pest
The pale potato cyst nematode (Globodera pallida) has been positively identified by Agricultural Research Service (ARS) scientists and cooperators in soil at a potato processing plant in eastern Idaho. This is the first time this pest--now of great concern in Europe--has been found in the United States. Removal Of Dominant Rivals Causes Male Cichlid Fish To Undergo Remarka
In a new study of cichlid fish descended from others caught in East Africa's Lake Tanganika, scientists have made some surprising observations about how those animals respond to changes in their environments known as "social opportunities." Bipolar Disorder Exacts Twice Depression's Toll In Workplace
Bipolar disorder costs twice as much in lost productivity as major depressive disorder, a study has found. Each U.S. worker with bipolar disorder averaged 65.5 lost workdays in a year, compared to 27.2 for major depression. Even though major depression is more than six times as prevalent, bipolar disorder costs the U.S. workplace nearly half as much -- a disproportionately high $14.1 billion annually, mostly due to bipolar disorder's more severe depressive episodes. Scientists Uncover New Mechanism For The Amygdala In Fear Recognition
A look of fear on another person's face is instantly recognizable. The split-second ability of the amygdala, a small, almond-shaped structure deep in the brain, distinguishes fear in facial expressions. In particular, the amygdala relies heavily on visual information contained in the eye region to detect fear. History Explorer: A Timeline of Stories From Our Exhibits, Collections

Simple And Inexpensive Landmine Detection System Is Under Development
Researchers are developing a radar system that might one day see through solid earth and could be used to clear conflict zones of landmines, safely and at low cost. The new technology, with further industrial development, could eventually make vast tracts of land around the globe safe once more.
