Leisurely walking for distance combined with low-impact cardiovascular activity appears to be the best formula for obese people seeking to get into shape and stay healthy, according to a University of Colorado at Boulder study.
Ray Browning, a doctoral student in CU-Boulders integrative physiology department and lead author on the new study, said the results show that people who walk a mile at a leisurely pace burn more calories than if they walk a mile at their normal pace. In addition, those who walk at 2 miles per hour rather than 3 miles per hour reduce the loads on their knee joints by up to 25 percent. "The message is that by walking more slowly, obese individuals can burn more calories per mile and may reduce the risk of arthritis or joint injury," he said.
Browning and his CU colleagues also found the number of calories burned per pound of body weight is similar for obese adults as normal sized adults walking at the same speed. Because obese people generally have heavier legs, wider stances and swing their legs in a wider arc, the researchers expected the cost of walking for obese people to be significantly higher. "This was a surprise," said Browning. "The subjects probably are unwittingly altering their posture and walking with straighter legs, conserving calories in the process." A paper by Browning, CU-Boulder integrative physiology Associate Professor Rodger Kram and undergraduates Emily Baker and Jessica Herron was presented at the June 2005 meeting of the American College of Sports Medicine meeting in Nashville and published recently in the journal, "Obesity Research."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
