Genetic engineering could make grapevines immune to a common virus that now results in smaller grapes and crop loss, German scientists said. Modified plants have produced antibodies against Grapevine fanleaf virus, caused by the vine louse, or rust mite, researchers at the Institute for Molecular Biology and Applied Ecology, in Aachen, said. These antibodies 'recognize' the viruses and prevent them from spreading in the plant and causing damage, said Dr.
Letting Pacific Northwest forests age longer would increase carbon storage and help mitigate greenhouse gas emissions, researchers in Oregon said. If, for example, the region's forests were allowed to increase in age by 50 years, their potential to store atmospheric carbon would increase by 15 percent, researchers at Oregon State University, Corvallis, said. That would significantly offset the nation's carbon budget since the Pacific Northwest accounts for 14 percent of the live biomass in the United States, said Beverly Law, a professor of forest science at the university. Law's team analyzed two decades worth of information from 15,000 forest plots in the North American Carbon Program.

Gene mutations that once helped humans evolve and survive could increase the risk of cancer and other diseases today, researchers in Israel said. The mutations were found in the genome of the mitochondria, the part of cells responsible for energy production that is passed from mother to child, scientists at Ben-Gurion University of the Negev said. Although mitochondria's role in the emergence of new species has been investigated recently, the idea that they are responsible for our susceptibility to illness startles many, Dr.
Stores in several states are removing tomato plants from their shelves as an infectious and destructive plant disease makes its earliest and most widespread appearance ever in the eastern United States.
