Key nutrients critical for older infants' development

SAN FRANCISCO (April 6, 2006) According to Nancy Krebs, M.D., a professor of Pediatrics at the University of Colorado Health Sciences Center and former Chair of the American Academy of Pediatrics (AAP) Committee on Nutrition, it can be difficult to meet the nutritional needs of older infants. Since human milk alone is no longer adequate to meet infant nutritional requirements after 6 months of...

ASU geologists suggest Mars features are result of meteorite strikes, not of evaporated lakes

Geologic features at the Opportunity landing site on Mars were formed not by a lake that evaporated but by constant strikes from meteorites, say two Arizona State University geologists. ...... The site where the Mars Exploration Rover Opportunity landed has sediments and layered structures that are thought to be formed by the evaporation of an acidic salty sea. The prevailing thought is that when...

Discovery in orange cauliflower may lead to more nutritious crops

While orange cauliflower may seem unappealing to some, it has distinct nutritional advantages. Now, Cornell researchers have identified the genetic mutation behind the unusual hue. The finding may lead to more nutritious staple crops, including maize, potato, rice, sorghum and wheat.... The genetic mutation recently isolated by Cornell plant geneticist Li Li and colleagues -- and described in th...

Studies assess effectiveness of serotonin and nerve stimulants on irritable bowel syndromes

WASHINGTON, D.C. (May 21, 2007) Studies have shown that gastrointestinal (GI) tract function is often influenced by specific stimulants or reactors, which sometimes cause irritable bowel syndrome (IBS) or constipation. Two studies presented today at Digestive Disease Week 2007 (DDW) take a closer look at GI stimulation, including one examining the role of serotonin and reactions to certain typ...
