Genetically modified (GM) corn won’t threaten native corn species in Mexico, according to a new report issued by the North American Free Trade Association (NAFTA).
In a country whose culture and identity revolve heavily around corn, or maize – the crop was first developed here thousands of years ago – the thought of imported GM varieties contaminating indigenous plants frightens many citizens, said Allison Snow, a co-author of the report and a professor of evolution, ecology and organismal biology at Ohio State University. Because of that fear, Mexico placed a moratorium on planting GM corn in 1998.
However, an estimated 30 percent of the corn that Mexico imports from the United States may be genetically modified, Snow said. The United States does not separate GM corn from non-GM corn, making it impossible for Mexican farmers to know if the grain they receive is genetically engineered or not. "Reliable unpublished data suggest that it is extremely likely that some GM corn is already growing in Mexico, whether it was intentional or not," said Snow, who is also an expert on plant-to-plant transmission of GM genes.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
