La ricerca scientifica italiana sarebbe pronta a fare produzioni che potrebbero portare grande vantaggio alle persone sia in termini economici che come garanzie per la salute umana. Ma questi interessi sono opposti a quelli di Greenpeace che deve solo badare a sopravvivere ed impedire che guardando con i loro occhi e ragionando con la loro testa quelle stesse persone capiscano in quale inganno siano caduti.

Scompare con Francesco Sala, uno dei maggiori scienziati italiani che hanno combattuto senza paure la battaglia in favore degli OGM.

Un ricordo di Futuragra, quello di Anna Meldolesi e uno di Roberto Defez su il Sole24Ore.

La Cina prende la leadership negli OGM

Le tre ultime copertine di Nature Genetics sono state dedicate alla genetica vegetale grazie sopratutto al lavoro dei ricercatori cinesi che hanno pubblicato studi avanzatissimi sulla genetica del riso, del mais ed ora della soia. Queste conoscenze mettono i laboratori cinesi nella miglior condizione per favorire i breeders locali e creare le nuova verietà che tra qualche anno si imporranno sui mercati. E chi non fa ricerca potrà solo scegliere quale OGM (Organismo Geneticamente Modificato) acquistare.

Golden Rice An Effective Source of Vitamin A

http://www.eurekalert.org/pub_releases/2009-05/bcom-gra051309.php

HOUSTON - (May 13, 2009) - The beta-carotene in so-called “Golden Rice” converts to vitamin A in humans, according to researchers at Baylor College of Medicine (www.bcm.edu) and Tufts University in an article that appears in the current issue of the American Journal of Clinical Nutrition.

Golden Rice was developed in the early 1990s with a grant from the Rockefeller Foundation with the goal of creating rice that had beta-carotene — a vitamin A precursor - in the rice grain. In its current form, Golden Rice contains 35 micrograms of beta-carotene per gram.

“We found that four units of beta-carotene from Golden Rice convert to one unit of vitamin A in humans,” said Dr. Michael Grusak (http://www.bcm.edu/cnrc/faculty/?PMID=9536), associate professor of pediatrics at the USDA/ARS Children’s Nutrition Research Center (http://www.bcm.edu/cnrc/?PMID=0) at BCM and Texas Children’s Hospital.

They determined this by feeding five healthy adults a specific amount of specially-labeled Golden Rice and measured the amount of retinol, a form of vitamin A, in the blood. Vitamin A deficiency is prevalent in many parts of the world where poorer community members rely on rice as their major food source. People who lack adequate amounts of this vitamin can have vision problems or even blindness as a result.

“By incorporating vitamin A into the major crop that is consumed, we would be able to make it accessible to the majority of people in the area,” said Grusak. Additional research is necessary before Golden Rice is made commercially available. The next steps of the research include incorporating this technology into the rice grains found in various regions and continuing testing the conversion rates in humans.

Others who participated in this study include Guangwen Tang, Jian Qin, Gregory G. Dolnikowski and Robert M Russell, all of the Jean Mayer US Department of Agriculture Human Nutrition Research Center on Aging at Tufts University.
