Despite the wrangling that's resulted in a government shut-down, Congress managed last week to agree on one thing: Helium. Reader gbrumfiel writes: "The U.S. holds vast helium reserves which it sells to scientists and private industry. According to NPR, a new law was needed to allow the helium to continue to flow. Congress passed it late last week, but only after a year-long lobbying effort and intense debate (and in the end, Senator Ted Cruz opposed the measure). Can a new bipartisanship rise out of this cooperation? Or will hot air prevail on Capitol Hill? (Insert your helium joke here.)" Apparently, helium is not yet so scarce that it's not available in balloons at the grocery store.
