When considering a tour of the Mississippi River, most people think of paddle boats or tubes, but Mike Mott wants you to think of Segways. Mott is working with Iowa officials and the city of Davenport to set up Segway tours along the Mississippi River recreational trail. "Mott said his tours will begin in the parking lot of the Union Station Visitors Center at 102 S. Harrison St. After a 20-minute safety orientation, the tours will proceed west to Credit Island, then back to the visitors center and east to the Davenport-Bettendorf border and back again. The tours will take about two hours and will include information about local history and sites of interest, Mott said."

The mecanism seems to be linked to oxidative stress at cellular level, that keeps the enzyme telomerase from regenerating the chromosomial telomere caps which shorten a bit during each replication cycle. Telomere caps are known to be a very important factor determining the replication capacity of every cell. Once these caps are gone,a cell goes to a state of senescence, and ultimately dies. People exposed to prolonged periods of stress have been shown to have significantly shorter telomere caps on the chromosomes of their white blood cells."
