But new research suggests we can measure a system without disrupting it to the degree that Heisenberg predicted. Is this the end of the famous principle?

The researchers are excited about the finding, but also say it does not qualify as a discovery. But why all the uncertainty? Why isn't the answer a simple yes or no? Today on the Physics Buzz podcast Calla Cofield talks with Dr. Bob Cousins about the uncertainty surrounding the search for the Higgs boson.</itunes:summary>
