February 12, 2013feature: Neutrinos, the Standard Model misfitsFor years, scientists thought that neutrinos fit perfectly into the Standard Model. But they don't. By better understanding these strange, elusive particles, scientists seek to better understand the workings of all the universe, one discovery at a time.

August 1, 2012feature: Voyage into the unknownIn the deep, dark quantum sea known as the Intensity Frontier, particle physicists expect to find everything from exotic new particles to new insights into the evolution of our universe. They are likely to discover the completely unexpected, changing our understanding of matter, energy, space and time.

June 5, 2012breaking: MINOS announces key neutrino measurementScientists from the MINOS experiment at Fermilab announced today the world’s most precise measurement of a key property of neutrinos. The results confirm that neutrinos and their antimatter counterparts, antineutrinos, have similar masses.

March 8, 2012breaking: Daya Bay experiment makes key measurement, paves way for future discoveriesAn international collaboration of physicists working on a neutrino experiment in southern China announced today they have made a difficult measurement scientists have been chasing for more than a decade. The results of the Daya Bay neutrino experiment open an important window into understanding the behavior of neutrinos, and now the race is on to determine the implications. Two American experiments, one proposed and one under construction, seem well positioned to take the next steps.

February 23, 2012breaking: Faster-than-light neutrinos explained?Albert Einstein's law of special relativity might shrug off the challenge of faster-than-light neutrinos after all. Scientists in the OPERA collaboration announced today that they have found two possible causes for the surprising results they presented in September 2011, in which neutrinos seemed to beat Einstein's cosmic speed limit.

December 5, 2011breaking: DOE's Intensity Frontier Workshop packed with ideas and peopleAs a postdoc, Giovanni Tassielli has the whole particle physics landscape to survey for the most stimulating future job prospects. The researcher from INFN in Italy feels a pull toward the most challenging experiments at the Intensity Frontier: those that seek out the rarest of all particle interactions, the smallest of effects and provide a glimpse of physics beyond what experiments at particle colliders can reach.

November 29, 2011breaking: D.C. workshop envisions the Intensity FrontierAt the Intensity Frontier, scientists use high energy beams and sensitive particle detectors to explore rare subatomic processes in search of answers to profound questions. More than 500 scientists are gathering this week to discuss the future role of the U.S. in these experiments. They will discuss the most exciting opportunities, the potential for new discoveries and the equipment and technology required for these new experiments.

November 17, 2011breaking: Pivotal pivoter test paves way for 15,000-ton plastic behemothIt could be the largest structure ever to be built from plastic. Its footprint of 1,052 square meters will cover an area about the size of a quarter of a football field. Its height will rise past the top of a five-story apartment building. And with 368,640 tubes of white PVC, the structure will have about as many components as some of the largest LEGO structures built in the world.

November 9, 2011breaking: Neutrinos make a splash in the SciBath detector at FermilabThe latest underground dweller in the MINOS tunnel is SciBath, a neutron and neutrino detector designed and built by an Indiana University team. Scientists are using the detector cube, which is about the size of a mini fridge, to track neutrons and neutrinos more effectively and economically.

October 28, 2011breaking: Scientists still seek explanation for faster-than-light neutrino resultThe question of whether the OPERA experiment's faster-than-light neutrino measurement is correct is still up in the air, despite what some headlines have suggested. Experimentalists have not been able to establish how the experiment is flawed, and yet theorists have not been able to determine how its conclusion could be true.
