Last August the Crandall Canyon Mine in Utah collapsed, killing six coal miners. Ten days later, three men sent to rescue the trapped miners died in a second cave-in. A Congressman has asked the U.S. Attorney for Utah to conduct a criminal investigation into whether the mine's general manager "willfully misled" federal officials.

House Education and Labor Committee Chairman George Miller of California asked prosecutors to determine if the general manager "covered up" conditions in the mine that could have warned federal inspectors of potential dangers. In particular, Miller said the mine manager did not report a significant damage from a mine collapse, or "bump," in March

Mine management at Crandall "may have purposefully misled MSHA about the severity of the March bump fearing MSHA would close the mine, and [they] continued to adhere to the mischaracterization after the August incidents in an effort to downplay the foreseeability of the August incident," Miller's report said.

How far are you from the nearest heart monitor or ultrasound machine or high-tech imaging equipment? Reach in your pocket. Soon, cell phones will be able to provide these and other medical diagnostics.

"The cell phone is going to solve rural health-care problems, whether it's rural India or rural Indiana," Kristin Tolle, Microsoft Research's program manager for external research in biomedical computing, told Business Week's Olga Kharif. Microsoft is funding 17 research efforts into using cell phones for an array of medical purposes.

Kharif writes that Apple's iPhone is being adapted for medical applications too. A new software program that works with the iPhone makes it possible to physicians far from a patient's bedside to review that patient's records -- even brain scans and X-rays -- with accuracy.

Buffalo from Monte Downare's ranch ran through the thin fence put up by Jeff Hawn, a newcomer to Park County, Colorado, and so Hawn allowed some hunters to kill 32 of the bison. The buffalo were left where they were shot, or where they eventually fell, and the community of Fairplay was thrown into an uproar, according to a story in the Los Angeles Times.

Colorado is an open range state and so the ethic and the law is that property owners are responsible for keep animals off their property — and that you never kill a neighbor's stock. But Hawn came from Texas, buying 365 acres (at best, a "ranchette") next to the Downare's place. The buffalo would cross Hawn's fence and the Downare's would come bring them back. Hawn claimed they did damage to his property, including destroying a satellite dish. And then the strong-willed bison crossed again and the animals were shot.

The incident has spawned lawsuits and a letter to the editor calling the hunters "gang-land style killers." Police are investigating.
