A collaboration of scientists mainly from the Fred Hutchinson Cancer Center and at the University of Washington (Seattle) has made an important discovery linking the powerful cancer-causing oncogene, myc, with the gene behind the premature aging disease, Werner syndrome. Their finding reveals that the MYC oncoprotein turns-on Werner syndrome gene expression, and posits the Werner syndrome gene as a potentially important participant in MYC-induced tumorigenesis.
Werner syndrome is a rare genetic disorder characterized by the appearance of old age beginning after puberty. It is caused by mutations in the Werner syndrome gene (WRN), which resides on the short arm of human chromosome 8. The WRN gene encodes a DNA helicase (an enzyme that unwinds DNA) involved in DNA replication and repair.
As published in the July 1 issue of Genes & Development, Dr. Carla Grandori and colleagues have discovered that WRN expression is regulated by the MYC oncoprotein, which is implicated in about one third of all human cancers.

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...
