Agricultural economist Graham Brookes of PG Economics Ltd, based in Dorchester, UK, has reviewed the specific economic impacts on yield and farm income as well as the environmental impact with respect to a lower reliance on insecticide usage since the introduction of GM maize in the EU in 1998.
So-called "Bt" maize carries genes for a highly specific insect toxin from the soil-dwelling microbe Bacillus thuringiensis. This toxin kills the European corn borer and the Mediterranean stem borer, which would otherwise damage maize crops without insecticidal spraying.
Brookes' analysis reveals that profits have risen by more than a fifth for some farmers who previously used synthetic insecticides to control these pests. He points out that GM technology has reduced insecticide spraying markedly, which also has associated environmental benefits. He also points out that the quality of the maize produced is higher because the GM crop is less susceptible than non-GM maize to infestation with fungi that produce mycotoxins, hazardous to human health.
Bt maize was planted for the first time in 1998 in Spain and in 2007 the total area of this crop in Spain was about 75000 hectares. In total, the EU plantings of Bt maize in 2007 were 110,000 hectares, with crops also in France, Germany, Portugal, Czech Republic, Slovakia, Romania and Poland. This represents 1.3% of total EU grain maize plantings in 2007.
Brookes points out that his findings are consistent with those seen in North and South America, South Africa and the Philippines. "In all countries where the technology has been adopted farmers have seen consistent increases in both yields and income levels, with annual and regional variations in impact reflecting the variable incidence of pest attacks and damage," he concludes.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
