National data reveal that foot and toe symptoms are among the top 20 reasons patients ages 65-74 visit their physician. In the U.S., foot pain is considered a very common musculoskeletal symptom and occurs in such conditions as rheumatoid arthritis, diabetes, and gout, or with sprains, muscle strains, bruises, and fractures. Previous studies have determined a correlation between improper footwear and foot pain, but this research focused on small patient samples or disease specific studies.
Researchers from Boston University School of Public Health and the Institute for Aging Research at Hebrew SeniorLife enrolled 3,372 participants in the Framingham Foot Study. Participants were derived from 2 large population-based samples of residents from Framingham, Massachusetts. The first group was part of the Framingham Study Original Cohort (formed in 1948) and the Framingham Offspring Cohort (formed in 1972) that were originally studied for heart disease risk factors. The second group was a new population sample derived from census data and included subjects who were at least 50 years old and ambulatory who were added to increase participation by minority persons.
The Framingham Foot Study assessed 1,472 men and 1,900 women between 2002 and 2008. Subjects were asked if they experienced pain, aching, or stiffness in either or both feet. Data on specific areas of foot pain was identified in the nails, forefoot, hindfoot, heel, arch of the foot, and ball of the foot. Participants provided information on current and past shoewear across five age groups: 20-29 years, 30-44 years, 45-64 years, 65-74 years, and 75+ years. Shoewear was classified as good (low risk shoes including athletic and casual sneakers), average (mid risk shoes such as hard- or rubber-soled shoes, special shoes and work boots), and poor shoes (high-risk shoewear that lack support and sound structure, including high-heeled shoes, sandals, and slippers).

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
