While experts disagree on whether work tasks alone can be the exact cause of work-related musculoskeletal disorders (WMSD) such as carpal tunnel syndrome, a new study by researchers at Temple University proves that a highly repetitive work task, a risk factor for WMSD, does in fact cause bone damage.
"Because multiple factors play a role in the development of WMSD, including work tasks, home activities, and medical conditions such as diabetes or heart disease, we studied work tasks alone to isolate their impact," said Ann Barr, P.T., Ph.D., associate professor of physical therapy at Temple University and the studys lead author. "This information is critical in helping industry and medicine establish workplace guidelines to prevent WMSD."
The study, "Repetitive, Negligible Force Reaching in Rats Induces Pathological Overloading of Upper Extremity Bones," published in the November 11 issue of the Journal of Bone and Mineral Research, is the third in a series conducted by a group of researchers at Temple Universitys College of Health Professions and School of Medicine. "Our studies have shown a direct relationship between repetitive, low force movement and the inflammation of muscles, bone, nerves and connective tissue typical of WMSD," said Barr.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
