The mysterious ways cancer spreads through the body, a process known as metastasis, is what can make it such a difficult enemy to keep at bay. Researchers at Princeton University working in this area have been tugging at a particular thread for more than 15 years, focusing on a single gene central to the ability of most major cancers to metastasize. They've now discovered what they describe as a "silver bullet" in the form of a compound that can disable this gene in mice and human tissue, with clinical trials possibly not too far away.
