In a study of rats, polyphenols in red wine or grape juice that help prevent Alzheimer's are absorbed better after continued ingestion, U.S. researchers say. Mario Ferruzzi, Connie Weaver and Elsa Janle of Purdue University in West Lafayette, Ind., and Dr. Giulio Pasinetti of Mount Sinai School of Medicine in New York say previous studies of a single or sporadic dose found little bioactive polyphenols reaching the brain. However, the study published in the Journal of Alzheimer's Disease,...

French winegrowers are harnessing the benefits of satellite imagery to enrich their grape harvests, combining modern technology with the ancient art of winemaking. Originally developed to help producers of grain, the Oenoview system combines satellite images and vine analysis to assist oenologists in determining when grapes planted under varying conditions will be ready for harvest. The system works by providing winemakers vital information about their berries, such as the amount of water the...
