Scientists at the University of Minnesota’s remote underground laboratory near Lake Kabetogama in northern Minnesota say they have received their first-ever long distance neutrinos beamed from the Fermi National Accelerator Laboratory near Chicago. It’s the world’s longest-distance neutrino experiment — with two huge particle detectors placed 500 miles apart and scientists trying to explore the properties of an intense beam of ghostly particles called neutrinos. The lab, about 30 miles southeast of International Falls, has been in the works for a decade.
SUPERIOR, Wis. — It’s just a small piece of the North American oil bonanza pie, but Wisconsin’s only refinery quietly is moving more oil by rail. In 2012, Calumet Superior LLC built a $10 million train-loading oil terminal across the street from its refinery on the south edge of Superior, adding 18,000 feet of new track. Calumet now is loading about 5,000 barrels (210,000 gallons) of oil per day by rail, said refinery manager Kollin Schade. “This was never intended to be a major part of our operations,” Schade said during a recent tour.
