Pope meets with family who drove 13,000 miles to see him

Pope Francis met Sunday with a family who made a 13,000-mile trip over 194 days from Argentina to Philadelphia in an old Volkswagen van. Francis spent time with fellow Argentinians Catire Walker and Noel Zemborain and their four children, talking about their visit and praying. Zemborain told the Associated Press that Francis told her that they were crazy to drive so far with their children. She said it was like meeting an old friend and Francis hugged the children. "We couldn't believe it. They called us this morning (and) we were like in shock," she said after Sunday night's Mass. "It is like being with an old friend. He was so warm. He told us we were crazy. He made jokes. "The children got to hug him a lot. They couldn't leave him. Not at all protocol, not at all formal, it was like being with a friend." Walker and Zemborain quit their jobs in food service and marketing to lead their children on the unforgettable tour of the Americas, using savings and soliciting donations to fund the trip to the World Meeting of Families in Philadelphia. Along the way they made 12 border crossings and stayed with dozens of host families, did lots of sightseeing and documented the trip online. They schooled their children — Cala, 12; Dimas, 8; Mia, 5; and Carmin, 3 — with the help of a distance learning program. The family said they got a call at 6 a.m. Sunday that Francis wanted to meet with them at the Saint Charles Borromeo Seminary, where he stayed this weekend. Francis told the family he had been following their trip, they wrote in a Facebook post. Zemborain, Walker and the kids plan to continue traveling until November, when they will fly home from Miami. They were going to send the van by ship, but then a relative volunteered to drive it back to Buenos Aires from Florida. Francis celebrated Mass on Sunday that drew hundreds of thousands to downtown Philadelphia. The Associated Press contributed to this report.

West Virginia researcher describes how Volkswagen got caught

The cheating scandal engulfing the world's largest automaker started with a road trip. In the spring of 2014, researchers from West Virginia were evaluating the tailpipe emissions of diesel cars made for the American market by European manufacturers, something never before studied in the academic realm. Excited by the prospect of breaking new ground, the team of two professors and two students wanted to gather as much data as possible. "And being academics, we went a little overboard," said Arvind Thiruvengadam, one of the students. "Being academics, we went a little overboard." Overboard included driving the cars for more miles than they needed to test and verify results. Drivers put about 1,500 miles on each of the first two cars in the study, a Volkswagen Jetta and BMW X5, along California roadways. For their final car, a Volkswagen Passat, they wanted even more mileage. So they took the car on a road trip from Los Angeles to Seattle and back again, collecting data from more than 2,000 miles of testing. The road trip was Volkswagen's undoing. When the West Virginia team returned to Los Angeles, they were befuddled by the test results. In theory, the Passat should have spewed the lowest levels of pollutants among the three cars. Equipped with the more modern selective catalytic reduction technology, the team expected to find minimal levels of nitrogen oxide. But the car, which had been certified at a California Air Resources Board facility prior to the start of the road trip, had elevated levels of NOx that were 20 times the baseline levels established beforehand. The researchers, comprised of professors Gregory Thompson and Dan Carder and students Marc Besch and Thiruvengadam, knew their on-board equipment functioned properly because, early in their research, they had double-checked its accuracy after recording sky-high NOx readings from the Jetta that showed 30 times the level of its baseline testing at the CARB facility. It was particularly noteworthy because the Jetta contained the first-generation Lean NOx Trap technology, not the more efficient SCR, yet both produced large discrepancies. The BMW, on the other hand, performed as expected. Today, Thiruvengadam is careful to say the research team never suspected Volkswagen of cheating on emissions testing, nor did the researchers report such a finding. They merely reported their findings to CARB officials who then further investigated.
