Each year more than 45,000 Americans suffer burns serious enough to require a hospital stay, according to the American Burn Association. While the traditional therapy of using skin grafts to cover burn sites has improved, a number of problems including scarring, infection and poor adhesion remain.
“Skin grafts involve taking skin (both the upper epidermal and the underlying dermis) from an unburned site on the patient’s body or from a cadaver and grafting it on to the burn wound,” said Craig D. Woodworth, a cell biologist and associate professor at Clarkson University. “Skin grafts often require multiple surgeries. Cadaver skin is scarce and can introduce disease. In the case of extensive burns, large amounts of skin can be created by isolating individual epidermal cells and then expanding their numbers in culture, but the skin simply does not look or function like normal skin. There are no hair follicles, no pores for sweating, and the pigment is often a poor match.”
Woodworth is collaborating with Anja Mueller, a polymer chemist and assistant professor of chemistry at Clarkson, on research to develop an artificial skin that would heal and function like normal skin and could be used successfully for large burns or surgical reconstruction.

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...
Breakthrough provides a new concept of the design of molecular motors, sensors and electricity generators at nanoscale

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...
