PITTSBURGH — The bishop of the Roman Catholic Diocese of Pittsburgh plans to take the ice bucket challenge to support a priest who has Lou Gehrig's disease, but says he will donate his money to a charity that doesn't use embryonic stem cells for its research.

Bishop David Zubik's announcement comes after the Archdiocese of Cincinnati discouraged its schools from raising money for organizations that conduct research on Amyotrophic Lateral Sclerosis, or ALS, using cells taken from human embryos.

The Pittsburgh diocese agrees with Cincinnati officials that such research violates the Catholic Church's teachings on abortion, said the Rev. Ronald Lengwin, a diocesan spokesman.

Zubik plans to take the challenge Saturday with the Rev. Dennis Colamarino, pastor of two parishes in Duquesne, who was diagnosed with the disease last year. Zubik will donate an undisclosed sum to the John Paul II Medical Research Institute, which uses only adult stem cells.

The ALS Association has raised $42 million in the past month due largely to ice bucket challenges, compared with about $2 million over the same period last year. The charity notes that donors can designate that their money not be used for research that uses embryonic stem cells.

SOMERSET — People who told police they were not that drunk while driving may have been right in one southwestern Pennsylvania county.Somerset County District Attorney Lisa Lazzari-Strasider said a hospital has been testing drivers' blood serum, not whole blood, when doing the tests.As a result, the blood-alcohol content has been overestimated by up to 15 percent.That's important because the blood-alcohol level is used to determine whether someone is legally drunk and, in some cases, whether they deserve more severe punishment.Tests using blood serum can be used as evidence, but only if a calculation is done to convert the percentage of alcohol found as though it were taken from a whole blood sample.The DA says her office failed to perform those calculations.
