BOSTON (AP) — The smell of burning bread crumbs has forced a Miami-bound American Airlines flight to return to Boston.

An airlines spokeswoman says Flight 1532 took off from Boston’s Logan International Airport at 6:36 a.m. Sunday, but passengers soon began smelling smoke.

The plane returned to Boston at 7:10 a.m., and the smell was found to be from bread crumbs burning in an oven. The oven was cleaned, and the flight took off again at 8:20 a.m.

The plane was carrying 150 passengers and five crew members.

BEAVER CROSSING, Neb. (AP) — Residents of the eastern Nebraska towns hit hard by tornadoes earlier this month are still cleaning up debris.

The Nebraska Emergency Management Agency says more than 700 volunteers were in Beaver Crossing Saturday to help the town’s 400 residents pick up.

Officials encouraged the volunteers to stay home on Sunday because heavy equipment will be used to pick up piles of debris that have been gathered since the May 11 tornadoes.

But volunteers will be needed again Monday.

Beaver Cross will hold a town hall at 6 p.m. Monday to discuss the tornado damage.

The tornadoes caused more than $20 million damage in several eastern Nebraska towns, but didn’t cause any serious injuries.

WASHINGTON (AP) — The U.S. government is stepping up efforts to help Central American farmers fight a devastating coffee disease — and hold down the price of your morning cup.

A fungus called coffee rust has caused more than $1 billion in damage across Latin American. The fungus is especially deadly to Arabica coffee — that’s the bean that makes up most high-end, specialty coffees.

It’s already affecting the price of some of those coffees in the United States.

The U.S. Agency for International Development is concerned about the economic security of small coffee farms abroad.

On Monday, agency head Raj Shah plans to announce a $5 million partnership with Texas A&M University’s World Coffee Research center to try to eliminate the fungus.

OMAHA, Neb. (AP) — The Omaha Public Power District has scheduled three public meetings to discuss its need for easements so a high-voltage transmission line can be built in southeast Nebraska.

The 180-mile line will eventually run from a substation at OPPD’s Nebraska City Station to a substation near Sibley, Missouri.

The district must negotiate with property owners to acquire easements in Otoe, Nemaha and Richardson counties. Construction is set to begin in summer 2015.

The first meeting is scheduled to run from 6 to 8 p.m. on Monday at the Lied Lodge in Nebraska City. The second will run from 6 to 8 p.m. Tuesday at the Falls City Middle School gym, and the third will run from 6 to 8 p.m. on Wednesday at the county fairgrounds 4-H building in Auburn.

OMAHA, Neb. (AP) — A senior administrator for the Centers for Disease Control and Prevention in Atlanta and former assistant surgeon general has been selected as the new dean of the University of Nebraska Medical Center College of Public Health.
