As the deadline for compliance with the Americans with Disabilities Act draws closer, the commuter and passenger trains used in large swaths of the United States remain inaccessible to passengers in wheelchairs. Meanwhile, the elevated platforms many regional rail systems have erected to address this problem have created another, forcing bulky freight shipments off the rails and onto some of the busiest roadways in the nation.
Enter an engineering professor from the University of Pennsylvania who has designed a new train car thats fully accessible to disabled passengers, compatible with freight trains and spacious enough to carry nearly 40 percent more passengers. The university has filed for patent protection.
"Current methods for boarding mobility-impaired passengers on commuter and intercity railroad trains are unsatisfactory from almost every perspective," said Edward K. Morlok, a professor of transportation and systems engineering. "The methods are demeaning to those passengers, create problems through delays and staffing requirements and can seriously interfere with freight shipping."

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
