The new test, reported in today's issue of Proceedings of the National Academy of Science, identifies replication errors in DNA that occur frequently in cancer. The errors, known as clonal markers, are used as a fingerprint for cancer.

Amid signs that the world's first SARS outbreak may have run its course, a leading World Health Organization official warned Thursday that detecting any recurrence of the pneumonia-like disease next winter will pose an entirely new set of medical challenges.
