Research published in the September issue of Medicine and Science in Sports and Exercise found that Minnesotans in the Twin Cities metro area are expending a significantly greater amount of energy participating in moderately intense physical activities than they were five years ago.
Of total lifestyle physical activity reported (yardwork, cleaning, plus leisure-time physical activity), 60 percent and 70 percent of energy expended for men and women, respectively, was spent in leisure-time physical activity. In the most recent survey, only 20 percent of women and 30 percent of men were meeting the one hour of physical activity a day recommended by the Institutes of Medicine to maintain weight and cardiovascular health.
The study also found that the percentage of Minneapolis-St. Paul metro area residents who sit for the majority of their work day increased from 57.4 percent to 71.2 percent since 1980, while the number of people who lift things frequently and walk more than a half mile to work dropped significantly.
"Physical activity has decreased over the past 20 years in the work place, which makes it more difficult for people to meet the recommendations for daily exercise," said Lyn Steffen, Ph.D., M.P.H., assistant professor of epidemiology and community health at the University of Minnesota School of Public Health. "But, people can help fill the gap by participating in physical activities that are part of a daily routine, such as walking their dog, climbing steps, walking, yardwork, and cleaning."
The study is part of the Minnesota Heart Survey and was designed to assess time trends in physical activity participation. Five population-based surveys were conducted from 1980 to 2002 within the seven-county Minneapolis/St. Paul metro area. Participants were asked to answer questions regarding the duration and frequency of their participation in 63 listed activities.
"Although energy expenditure was lower than national recommendations and Body Mass Index (BMI) rates continued to increase in general over the past 20 years, BMI levels in active adults increased at a slower rate than less active adults," said Steffen. "Reengineering our culture and environment to include more physical activity opportunities in routine leisure, job, and transportation would facilitate healthy lifestyles."

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
