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 "Reliable unpublished data suggest that it is extremely likely that some GM corn is already growing in Mexico, whether it was intentional or not," said Snow, who is also an expert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.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
