The hassle of removing and cleaning your contacts every night, or even every month, could become a thing of the past, based on a study involving a new contact lens coating that kills bacteria.
The study involved rabbits. The coating: an extremely thin layer of selenium, a naturally occurring element found in soil, some plants and many foods we eat.
The rabbits showed no ill effects after two consecutive months of wearing the coated lenses, according to Ted Reid, Ph.D., of Texas Tech University Health Sciences Center in Lubbock, Texas, who presented the findings at the 224th national meeting of the American Chemical Society, the worlds largest scientific society.

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...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
