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."

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
