In the race to cure cancer, researchers look for roadblocks that could stop cancer in its tracks, preventing it from spreading to other parts of the body. Scientists from the University of Wisconsin-Madison may have found that blockade - an enzyme critical to the ability of cells to metastasize, a biological phenomenon by which cells migrate. The findings are published in the Nov. 7 issue of the journal Nature.
"The real, life-threatening problem with most cancers is that they migrate away from the initial site," says Richard Anderson, a UW-Madison pharmacology professor and senior author of the paper. "If we could regulate a cells ability to move in a selective way, we may be able to block cancer metastasis."
Researchers have identified several important factors involved in cell migration, but they continue to search for the mechanisms that regulate these key factors. Anderson and his group have found that the enzyme, noted scientifically as PIPKI?661, appears to underpin cells ability to move from organ to organ.

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...
