The world's first human trial of pro-vitamin A-enriched bananas will start soon, with the goal of improving the health status of millions of Ugandans. The project, led by Professor James Dale, aims to increase the level of pro-vitamin A in bananas to 20 micrograms per gram dry weight.
The European Union's current policies on genetically engineered crops are undermining its competitiveness and humanitarian activities in the developing world. The authors recommend adopting rational, science-based principles to prevent economic decline and lower standards of living across the continent.
A study by Washington State University finds that genetically modified crops have led to a 25% increase in herbicide use, driven by the emergence of glyphosate-resistant weeds. The annual herbicide usage has grown from 1.5 million pounds in 1999 to 90 million pounds in 2011.
A new study by the University of Minnesota researchers found that APHIS failed to recognize environmental impacts and made legal errors in regulating genetically engineered crops. The agency's regulatory decisions have faced criticism, leading to litigation delays in the development of new GE crops.
A study found that Bt corn's pest suppression benefits non-Bt farmers in Wisconsin by up to 75%, with total economic benefits exceeding $6.9 billion across the Midwest. The primary benefit of Bt corn is reduced yield losses, which non-Bt farmers also experience without paying Bt technology fees.
A new study from the University of Minnesota found that genetically modified Bt corn reduces pest losses in both transgenic and non-transgenic corn. The study found that areawide suppression of European corn borer populations resulted in estimated annual losses of $1 billion, but also benefited non-Bt corn by 28-73% in neighboring states.
