Multiple hazards present; study cites threat of terrorism, transmission of infectious diseases, and new data on noise levels
Although information on subway safety is generally very limited, a new paper by safety experts at the Columbia Universitys Mailman School of Public Health provides the first comprehensive look at health and safety hazards that might affect both riders and subway workers. The report, published in the Journal of Urban Health in a special issue on mass transit, indicates that while subways in general, and the New York City subway system in particular, are relatively safe, especially in comparison to automobile use, a number of concerns remain.
According to lead author, Robyn Gershon, DrPH, associate professor of Sociomedical Sciences at the Mailman School, "Data on subway safety issues are limited, and much more research in this area is warranted given that millions of people are potentially at risk- in New York City alone, the weekday ridership is over 7 million passengers. "While this comprehensive review of the data gives us the first big picture into the health of our transportation system, without further appropriate risk assessment studies, we cannot adequately determine the factors and health effects of potential hazards," and "most importantly, the steps that are needed to reduce this risk," Dr. Gershon cautions.

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.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
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...
