With help from a common aquarium pet and a recently released online database of human genetic variation, a collaborative team of Penn State researchers has found what could be the most important skin color gene identified to date.
The team, led by cancer geneticist Keith Cheng, M.D., Ph.D., a Jake Gittlen Cancer Research Foundation researcher in the Penn State Cancer Institute, at Penn State College of Medicine, Penn State Milton S. Hershey Medical Center, in collaboration with University Park anthropologist Mark Shriver, Ph.D., found that a change in just one amino acid in one gene plays a major role in determining why people of European descent have lighter skin than people of African descent.
The find could lead to further research using the protein coded by the pigmentation gene as a target for treatment of malignant melanoma, the most deadly form of skin cancer, as well as to research on ways to modify skin color without damaging it by tanning or using harsh chemical lighteners.

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...
