Probing the last genomic frontier of higher organisms, an international team of scientists has succeeded in sequencing a little understood - but critical - genetic domain in rice.
In doing so, the group, led by Jiming Jiang, a professor of horticulture at the University of Wisconsin-Madison, and C. Robin Buell of the Institute for Genomic Research in Rockville, Md., has exposed a supposedly barren region of a rice chromosome known as the centromere. The work, published in the current (Jan. 11) online editions of the journal Nature Genetics, reveals for the first time that a native centromere, typically composed of enormous spans of indecipherable, non-coding DNA, contains active genes.
The feat promises to help fill in a key genetic void and enhance the scientific understanding of chromosomes, the molecular structures that are found in all animal and plant cells, and are the essential carriers of hereditary information, enabling the processes of cell division and replication.

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...
