(PhysOrg.com) -- Scientists in Cambridge have discovered that a lowly grape variety grown by peasants - but despised by noblemen - during the Middle Ages was the mother of many of today`s greatest grape varieties, including the Chardonnay used in Champagne. http://www.physorg.com/news180366830.html Biology Fri, 18 Dec 2009 13:54:21 EST news180366830 Getting the most out of every drop of water is a high priority for grape growers in the southern Napa Valley, where summers are hot and dry and vines have to be irrigated to make it through the growing season. But Stanford researchers have found that a significant portion of the water applied to the vines zips right by the plants, hardly even pausing. http://www.physorg.com/news180182242.html Space & Earth Wed, 16 Dec 2009 11:00:03 EST news180182242 Predictions of grape yields are extremely important to juice processors and wineries; timely and precise yield forecasts allow producers to plan for harvest and move the highly perishable grape crop from vine to processing efficiently. Until recently, wineries and grape juice processors have relied on expensive and labor-intensive hand-sampling methods to estimate yield in grape crops. http://www.physorg.com/news176560015.html Biology Wed, 04 Nov 2009 16:30:02 EST news176560015 (AP) -- Everyone likes a wine with character. How about one with 140 of them? Yes, the people at Twitter - the social media site on which users post messages no longer than 140 characters - are getting into the wine business, putting together an ambitious project aimed at raising money for literacy. http://www.physorg.com/news174819864.html Technology Thu, 15 Oct 2009 10:04:49 EST news174819864 A naturally produced molecule called resveratrol, found in the skin of red grapes, has been shown to lower insulin levels in mice when injected directly into the brain, even when the animals ate a high-fat diet. http://www.physorg.com/news174804190.html Medicine & Health Thu, 15 Oct 2009 05:43:55 EST news174804190 After analysing different points of the process of the transformation of grape juice to wine, Ms Ana González Marco concluded that the type of container (wooden cask or steel tank) employed notably influences the fermentative aroma of Chardonnay wine, and that oak cask-fermented wines have, in general, a greater concentration of superior alcohols and esters of medium-sized chains of fatty acids. http://www.physorg.com/news160305673.html Other Sciences Thu, 30 Apr 2009 10:21:25 EST news160305673 Can a grape-enriched diet prevent the downhill sequence of heart failure after years of high blood pressure? http://www.physorg.com/news159644910.html Medicine & Health Wed, 22 Apr 2009 18:49:01 EST news159644910 An extract from grape seeds forces laboratory leukemia cells to commit cell suicide, according to researchers from the University of Kentucky.

And could grapes calm other factors that are also related to heart diseases such as heart failure? A new University of Michigan Cardiovascular Center study suggests so. http://www.physorg.com/news144484064.html Biology Wed, 29 Oct 2008 07:27:44 EST news144484064 An herbicide that is effective at killing broadleaf weeds in corn, but also annihilated most of the grapes in Illinois and other Midwestern states, may finally have a worthy contender. Researchers at the University of Illinois have developed a new grape called Improved Chancellor which is resistant to the popular herbicide 2, 4-D. http://www.physorg.com/news143219362.html Biology Tue, 14 Oct 2008 16:09:22 EST news143219362
