When introduced to the world in 1998, human embryonic stem cells were considered heralds of a new age of transplant medicine. The prospect of an unlimited supply of cells and tissue of all kinds to treat disease captured public imagination and enthusiasm.
But lost in the glitz of the cells potential to treat an array of devastating and sometimes fatal diseases was another quality that, when all is said and done, could match even the prospect of remaking transplant technology.
"Much of the excitement surrounding embryonic stem cell research focuses on their potential for transplantation to repair diseased organs," according to Thaddeus G. Golos, a University of Wisconsin-Madison professor of obstetrics and gynecology. "The cells are also a valuable model for beginning to understand the puzzles of early human development."

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...
