However, a new study published today in the Journal of Hospital Medicine shows that after an eight-hour day, there is no difference in contamination of long- and short-sleeved shirts, or on the skin at the wearers' wrists.
A group of researchers from the University of Colorado, USA, decided to assess the accuracy of the assumption that longer sleeves lead to more contamination by testing the uniforms of 100 physicians at Denver Health randomly assigned to wearing a freshly washed, short-sleeved uniform or their usual long-sleeved white coat. "We were surprised to find no statistical difference in contamination between the short- and long-sleeved workwear," said lead researcher Marisha Burden, MD. "We also found bacterial contamination of newly laundered uniforms occurs within hours of putting them on."
50 physicians were asked to start the day of the trial in a standard, freshly washed, short-sleeved uniform, and the 50 physicians wearing their usual long-sleeved white coats were not made aware of the trial date until shortly before the cultures were obtained, to ensure that they did not change or wash their coats. Cultures were taken from the physicians' wrists, cuffs and pockets. No significant differences were found in bacteria colony counts between each style.
The researchers also found that although the newly laundered uniforms were nearly sterile prior to putting them on, by three hours of wear nearly 50% of the bacteria counted at eight hours were already present.
"By the end of an eight-hour work day, we found no data supporting the contention that long-sleeved white coats were more heavily contaminated than short-sleeved uniforms. Our data do not support discarding white coats for uniforms that are changed on a daily basis, or for requiring health care workers to avoid long-sleeved garments," concluded Burden.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
