DES MOINES, Iowa (AP) — In vast stretches of the Plains and Northwest known for wheat production, fewer farmers are growing wheat. They’re responding to low wheat prices and changing consumer tastes for high protein foods like hummus, pasta and energy bars, which are increasing demand for alternative crops such as garbanzo beans and lentils. This year, farmers planted the fewest acres of wheat since the U.S. Department of Agriculture began keeping records nearly a century ago.

DES MOINES, Iowa (AP) — Iowa is having trouble hiring enough registered nurses to treat inmates at state prisons, so it’s turning to workers with fewer credentials to fill a gap created in part by more competitive benefits in the private sector. Some unions representing Iowa nurses argue the staffing shortage will only worsen as the effects of recent changes to the state’s collective bargaining law begin to set in, though the Iowa Department of Corrections says it’s too early to know its impact on hiring.

DES MOINES, Iowa (AP) — Des Moines police say a man has died from the severe burns he received in a vehicle fire, and investigators are treating the case as a homicide. Firefighters responded Friday afternoon to a fire and found two vehicles aflame. Crews also found a man severely burned. The man died of his injuries Sunday. Police are withholding his name until his relatives can be notified. Investigators have determined the fire was intentionally set and consider the death a homicide.

DES MOINES, Iowa (AP) — Thousands of people pass through the State Historical Museum of Iowa’s Civil War exhibit, but visitors usually don’t see the 34 Confederate battle flags tucked away in the museum’s underground vault. Communications manager Michael Morain tells the Des Moines Register that the flags are not on display because they are not central to the history of Iowans on display in the exhibit.
