People generally worry about who their neighbors are, especially neighbors of our children. If high-fat food and soda are nearby, people will imbibe, and consequently gain weight. Or will they?
With students' health at risk, a study in the July/August 2011 issue of the Journal of Nutrition Education and Behavior explores the influence food store locations near schools has on the student risk of being overweight and student fast-food and sweetened beverage consumption.
Investigators from the University of Southern Maine surveyed 552 students at 11 Maine high schools to determine height, weight, and calorie-dense food consumption of ninth through twelfth grade students. Findings from the study reveal that half of the students consumed soda at least once a week and just over 10% consumed it daily, with a slightly smaller number consuming sports drinks in these time periods. In addition, nearly two thirds had visited a burger and fries fast food restaurant in the previous month, whereas over half had visited a pizza parlor during that period. Of the 552 students surveyed, one quarter of students were overweight (12.7%) or obese (12.5%), whereas 73% were of normal weight and 1.8% were underweight.
Surprisingly, this study found no correlation between students' overweight risk and the presence of stores with unhealthful food choices near their schools. Dr. David E. Harris, Professor at University of Southern Maine, states, "This study reports that the consumption of sweetened drinks and fast food among Maine high school students is high. One-half consumed sweetened soda weekly, and over two-thirds consumed fast food monthly, and students access these food items at a myriad of different locations. However, the proximity or density of stores with unhealthful food near Maine high schools does not predict the risk of overweight for students at these schools. This finding suggests that high school nutrition programs that focus on student behavior may be more effective than programs that focus on the built food environment near the school, at least in a predominantly nonurban setting such as Maine."
This study documents the importance of identifying determinants that influence adolescents' risk of being overweight. The researchers emphasize that "until unhealthful food choices are reduced overall, it is not surprising that the presence of food stores near their schools has little impact on students' risk of being overweight."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

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...
