(AP) — Billionaire Warren Buffett says he hopes his son’s new book about his efforts to fight hunger will inspire other people to get involved and make smart choices with philanthropy.

Buffett appeared alongside his son, Howard G. Buffett, and grandson, Howard W. Buffett, on Bloomberg television Tuesday. The men gave several interviews promoting the younger Buffetts’ new book “40 Chances: Finding Hope in a Hungry World.”

Warren Buffett says one of the challenges of philanthropy is there really isn’t a competitive market to test what ideas are working, so donors have to be smart.

Buffett is gradually giving his fortune to five foundations and entrusting them to distribute it, and each of his three children run one of the foundations.

(AP) — A construction worker in Lincoln has been hospitalized after receiving some kind of shock while on the job.

The man was doing directional drilling Tuesday morning on the city’s northwest side when the incident occurred.

The worker was not seriously injured. Authorities are trying to determine if he was electrocuted or exposed to an arc flash.

Lincoln Electric System says the incident created a brief power outage for about 2,000 customers.

Authorities have not released the worker’s name.

(AP) — Move over, silver.

After more than a decade as the world’s favorite car color, silver is falling in popularity to white. PPG Industries, the leading supplier of automotive paints, says 25 percent of the vehicles it supplied in the 2013 model year were white. Silver and black tied for second, with 18 percent each.

Apple Inc., with its white stores and slim white gadgets, made white a high-tech color. The variety of whites — from flat shades to creamy pearls — is also contributing, says Jane Harrington, PPG’s manager of automotive color styling.

Harrington says automakers are currently scouting colors for the 2016 and 2017 model years. She predicts jewel-like colors such as rich greens and deep purples will be popular. Grays and browns are also gaining.

(AP) — The Nebraska Court of Appeals has reversed a Douglas County juvenile court’s decision to terminate the parental rights of a father who spent time in jail for domestic violence against his son’s mother.

The juvenile court terminated the parental rights of the father, referred to only as Jerry S. in the opinion, last year.

A caseworker testified at trial that Jerry should lose his parental rights to his son, a toddler, because of a history of domestic violence, among other things. But the caseworker also testified that Jerry had made several improvements, including taking GED classes, attending Alcoholics Anonymous meetings and completing anger management classes.

On Tuesday, the appeals court found that there was insufficient evidence to prove that termination of Jerry’s parental rights was in the child’s best interests.

(AP) — Oral arguments are scheduled for December in a motion to dismiss a defamation lawsuit over ABC News’ coverage of a meat product that critics dub “pink slime.”

The lawsuit filed by Beef Products Inc. was moved in June from federal court to circuit court. ABC is asking the circuit judge to dismiss the case.

Dakota Dunes-based BPI claims the TV network damaged the company by misleading consumers into believing that its signature product — lean, finely textured beef — is unhealthy and unsafe. It is seeking $1.2 billion in damages.

BPI officials say the product is safe and the coverage led to the closure of three plants and roughly 700 layoffs.

The Elk County Clerk of Courts office says the hearing is scheduled for Dec. 17 at 1 p.m.

(AP) — Two Colorado farmers whose cantaloupes were tied to a 2011 listeria outbreak that killed 33 people have pleaded guilty to misdemeanor charges.

Eric and Ryan Jensen pleaded guilty Tuesday in federal court in Denver to six counts of introducing adulterated food into interstate commerce.

A sentencing hearing has been set for Jan. 28. The deal didn’t address the brothers’ possible punishment.

Officials say people in 28 states ate the contaminated fruit and 147 were hospitalized.

A statement from the Jensens’ attorneys says the brothers were shocked and saddened by the deaths, but the guilty pleas do not imply any intentional wrongdoing or knowledge that the cantaloupes were contaminated.

The brothers have sued the safety auditor who gave their farm a superior rating just before the outbreak.

(AP) — A 53-year-old man has died after being buried under a pile of silage at a feedlot in northeast Nebraska.

Stanton County Sheriff Mike Unger says the accident that claimed the life of Matthew Winkelbauer on Monday afternoon also injured 60-year-old Weldon Marotz Jr.

Unger says the pile fell onto the two in an open silage pit at the Fore-Quarters Feedlot southeast of Norfolk. Winkelbauer, of Norfolk, was pronounced dead at the scene. Marotz, of Stanton, has been flown to an Omaha hospital.

The accident is being investigated.

(AP) — Sen. Marco Rubio says he’ll introduce legislation to delay the penalty that can be assessed on individuals who don’t buy insurance under the government’s new health care law.

The Florida Republican says people should not be punished for not buying the insurance when major technical problems have plagued the online sign-up process. Uninsured Americans have until about mid-February to sign up for coverage if they are to meet the law’s requirement that they be insured by the end of March. If they don’t, they will face a penalty.

Rubio said on “CBS This Morning” show Tuesday that he still believes the health care law itself should be repealed.

President Barack Obama on Monday acknowledged technical problems that he described as “kinks in the system.”

(AP) — The husband of an Omaha woman who authorities say was among four slain by a man recently released from prison has filed a $7.5 million claim against the state of Nebraska.

The claim filed Monday for Michael Kruger says the death of 33-year-old Andrea Kruger could have been prevented. A claim against a governmental entity is a required Nebraska legal step before a lawsuit can follow.

Twenty-seven-year-old Nikko Jenkins has pleaded not guilty to killing Kruger and three other people within a month of leaving prison on July 30. He had served more than a decade for robbery, assault and weapons convictions.

A spokeswoman for the Nebraska Department of Correctional Services says prison officials could not comment.

(AP) — The last of the quintuplets born July 25 in Omaha has gone home to Sioux City in northwest Iowa.

Rosalyn Garcia left Methodist Women’s Hospital on Monday. She’s been there since she and her siblings were delivered via cesarean section. Her sister Jimena went home Sunday, joining their sisters Marah and Arleth and brother, Christobal.

Their mother and father, Bianca and Jose Garcia, also have two older sons: 9-year-old Jose and 7-year-old Abrahan.

Bianca Garcia was on bed rest for more than 10 weeks before the babies were born at 28 weeks, or about three months premature. A team of 35 doctors and nurses delivered the babies, who weighed a little more than 10 pounds total at birth.
