Researchers from around the world are gathering in St. Paul this week to talk about the possible dangers in fibers in taconite ore. Those microscopic fibers are a lot like asbestos, and asbestos causes cancer. Some studies show the fibers in taconite cause cancer too. Organizers of this week's conference will try to determine once and for all whether taconite fibers pose a health risk. The answer could have a big impact on future mining projects, and the economy of northeastern Minnesota.
