The BAMSE project has monitored 4,000 children in Stockholm county from birth in order to assess whether exposure to traffic pollution during their first year of life affects the risk of developing asthma and allergies. Levels of traffic exhaust were measured at the site of the home.
The results show that the children who were exposed to high concentrations of pollutants ran a 60 per cent higher risk of suffering of persistent asthma symptoms. Respiratory function was also adversely affected, and the children were much more likely to be allergic to airborne allergens, particularly pollen.
Studies were also made of how the risk of developing air pollution-related allergies is influenced by genetic factors. It was found that children carrying a variant of GSTP1 (glutathione S-transferase P1) gene, which is crucial to the body’s ability to take care of air pollutants (the antioxidative system), run a greater risk of developing an allergy linked to traffic-related air pollution. According to new analyses, variants of another ‘asthma gene’, TNF (tumour necrosis factor), also affect sensitivity to air pollution. Children with a particular combination of GSTP1 and TNF variants run a considerably higher risk of developing allergies.
The children studied in the BAMSE project are now 12 years old, and an on-line follow-up survey of the children and their parents has now been launched. The answers to the survey will provide information about health, lifestyle and environmental conditions, including air pollution, during the children’s lives.
1.Children who grow up in Stockholm are at greater risk of developing asthma, respiratory problems and pollen allergies if they live in areas where there are high concentrations of traffic pollution.
2.Not all children who live in areas with high levels of air pollution develop allergies. Whether they do or not is partly determined by genetic factors.
3.For the first time, data are now obtained for the BAMSE project using web-based techniques, which give more reliable answers.

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...
