Study underscores the importance of non-coding DNA in disease determination
Today a team of scientists provides convincing evidence that the deletion of a large non-coding DNA segment on human chromosome 17 is responsible for Van Buchem disease. This genetic mutation is one of only a few disease-associated mutations discovered to date that alters a long-range transcriptional regulatory element. The study appears online in the journal Genome Research.
"Our study addresses a fundamental issue with regards to the majority of the human genome that is non-coding in nature, and its potential impact on human health," explains Dr. Gabriela Loots, a scientist in the Department of Genome Biology at Lawrence Livermore National Laboratory who headed the study. "Non-coding regions located far away from the genes they regulate are critical for normal gene expression and are capable of leading to dramatic abnormal phenotypes if altered or deleted."

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...
