The brutal, unrelenting cold that lasted for several days over the Christmas holiday froze off a sizable portion of Appalachia’s ample gas production, cutting off supply to power plants when they needed it most. Gas transmission pipelines said the gas they were promised simply didn’t show up. On the electric grid that connects Pennsylvania to 12 other states, at one point almost 25% of the capacity on the system either didn’t start up or broke while operating, leaving coal and petroleum-fired units to pick up the slack. PJM, a Valley Forge-based grid operator, is still analyzing what happened during the...

Container's material properties affect the viscosity of water at the nanoscale Sep 19, 2013 Enlarge Georgia Tech associate professor Elisa Riedo poses with a glass water bottle and a plastic water bottle. While container materials don't significantly affect the rate at which water pours from bottles of this size, a new study shows that the properties of containers at the nanoscale dramatically affect the viscosity of water. Credit: Rob Felt Water pours into a cup at about the same rate regardless of whether the water bottle is made of glass or plastic. But at nanometer-size scales for water and potentially...

Eugene, Ore., social service agency salvages airport toiletries The Associated Press   EUGENE, Ore. (AP) — Airport discards in the response to a terror plot have turned into balm for the homeless in Eugene. The St. Vincent de Paul Society of Lane County has started picking up some of the things people have jettisoned for security reasons as they board flights at the Eugene Airport. Charley Harvey, assistant executive director of the charity, dug through trash bags Tuesday and took every bottle of shampoo and shaving cream he could find. The items will be distributed at the organization's First Place...

THE SAFEST airline in the world, it is widely agreed, is El Al, Israel's national carrier. [...] But in telling ways, the two experiences remain notably different. For example, passengers in the United States are required to take off their shoes for X-ray screening, while passengers at Ben Gurion are spared that indignity. On the other hand, major American airports generally offer the convenience of curbside check-in, while in Israel baggage and traveler stay together until the security check is completed. Screeners at American airports don't usually engage in conversation with passengers, unless you count their endlessly repeated instructions about...

Q&A: Liquid explosives An alleged plot to blow up planes from the UK mid-flight and cause "mass murder on an unimaginable scale" has been disrupted, Scotland Yard has said. It is thought the plan was to detonate explosive devices smuggled in hand luggage on to as many as 10 aircraft. BBC security correspondent Gordon Corera said the plan "revolved around liquids of some kind". One theory is that the attack may have involved liquid explosive being carried on to a plane in either drink bottles or cans. Dr Clifford Jones, an explosives expert from the University of Aberdeen, says even...
