Researchers identify key to cancer cell mobility

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 Wisonsin may have found that blockade – an enzyme critical to the ability of cells to metastasize, a biological phenomenon by which cells migrate.

Genes, Neurons, Internet Found to Have Organizing Principles-Some Identical

How do 30,000 genes in our DNA work together to form a large part of who we are? How do one hundred billion neurons operate in our brain? The huge number of factors involved makes such complex networks hard to crack. Now, a study published in the October 25 issue of Science uncovers a strategy for finding the organizing principles of virtually any network ? from neural networks to ecological food webs or the Internet.
