A physical map of the genetic makeup of a mouse - the mouse genome - is 98 percent complete and is being released online by the journal Nature. Researchers at the Genome Sequencing Center at Washington University School of Medicine in St. Louis played a major role in the international effort, as they did in the sequencing and mapping of the human genome.
"The mouse plays a vital role in research on human biology and disease," says John D. McPherson, Ph.D., associate professor of genetics and the lead investigator on the St. Louis team. "This physical map gives us the big picture of the mouse genome. It will be tremendously helpful to medical investigators and to those studying the human genome."
Comparison of the mouse and human maps, for example, can highlight regions of DNA that control genes. These regions are crucial to understanding the role of genes in health and disease, but they are difficult to find using current methods.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
