Space Sentinels Track Desertification On Mediterranean Shores
The severe droughts and forest fires of recent years underline Mediterranean Europe's continuing vulnerability to desertification -- 300 000 square kilometres of territory are currently affected, threatening the livelihoods of 16.5 million Europeans. A new satellite-based service is set to provide a continuous monitoring of regions most at risk. Killer Dinosaurs Turned Vegetarian: Utah Dinosaur Bones Reveal Missing

Protein Helps Regulate The Genes Of Embryonic Stem Cells
New research from University of North Carolina at Chapel Hill shows how a protein may be crucial to the regulation of genes in embryonic stem cells. Invisible Gases Form Most Organic Haze In Urban, Rural Areas
A new study shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world. Aerosols formed chemically in the air account for about two-thirds of the total organic haze in urban areas and more than 90 percent of organic haze in rural areas. 'Pony Express' Protein Shown To Rally Biological Clock
A biologist at Washington University in St. Louis and his collaborators have identified the factor in mammalian brain cells that keeps cells in synchrony so that functions like the wake-sleep cycle, hormone secretion and loco motor behaviors are coordinated daily over a 24-hour period. Pigments In Corn, Squash And Other Vegetables May Help Protect Against
