The use of nanomaterials in agriculture could, on the one hand, reduce cost and effort, increase efficiency and lead to more environmentally sound applications. On the other hand, it might also have a negative effect on microorganisms in the soil. This is concluded by the authors of a review article written within the scope of the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64).
Although no plant protection products or fertilisers containing nanomaterials are available on the market as yet, nanomaterials are becoming an increasingly important issue in agriculture, particularly as additives or agents in fertilisers or plant protection products: The number of scientific publications and patents on nanomaterials in this area has increased exponentially since the turn of the millennium, according to a review article recently published by researchers from the Agroscope Reckenholz-Tänikon Research Station and the Federal Office for Agriculture (*). With around 70 articles published until now, it is still possible for researchers to gain an overview of the topic. The USA and Germany are leading the field with regard to patents, but most of the scientific articles have been written in Asian countries.Often outside the traditional nano range
Companies in Switzerland are already required to declare any nanomaterials contained in new plant protection products that they wish to register. However, international principles of nano-specific risk assessment are still at the development stage. As part of the National Research Programme "Opportunities and Risks of Nanomaterials" (NRP 64), the project NANOMICROPS (Effects of NANOparticles on beneficial soil MIcrobes and CROPS) is contributing to these efforts by developing ecotoxicological test systems for soil microorganisms and crops as well as making available analytical methods for quantifying nanomaterials in agriculturally significant environmental compartments such as soil and water.(*) Alexander Gogos, Katja Knauer, and Thomas D.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
