In a finding akin to discovering pages missing from an antique car repair manual, researchers from The University of Texas M. D. Anderson Cancer Center have linked for the first time two biological processes crucial to cell survival.
The finding, reported in the Dec. 17, 2004, issue of the journal Cell, provides the first link between a cell’s DNA repair machinery and its DNA storage and retrieval machinery. The two processes have been studied independently, and each is essential for proper care and maintenance of the cell’s genetic material, but until now there was little evidence of how the two might work together.
"We have brought together two fields that are essential for proper maintenance of DNA," said Xuetong "Snow" Shen, assistant professor in the Department of Carcinogenesis at M. D. Anderson. "It was generally understood there must be a connection between the two, but no direct connection had ever been seen. We have bridged that gap."

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...
