A second experiment at the European facility that reported subatomic particles zooming faster than the speed of light - stunning the world of physics - has reached the same result, scientists said [today]. The positive outcome of the [second] test makes us more confident in the result," said Fernando Ferroni, president of the Italian Institute for Nuclear Physics. Ferroni is one of 160 physicists involved in the international collaboration known as OPERA (Oscillation Project with Emulsion Tracking Apparatus) that performed the experiment. While the second experiment "has made an important test of consistency of its result," Ferroni [said], more tests are needed. There is still a large crowd of skeptical physicists who suspect that the original measurement done in September was an error. Should the results stand, they would upend more than a century of modern physics. In the first round of experiments, a massive detector buried in a mountain in Gran Sasso, Italy, recorded neutrinos generated at the CERN [European Council for Nuclear Research] particle accelerator on the French-Swiss border arriving 60 nanoseconds sooner than expected. In recent weeks, the OPERA team tightened the packets of neutrinos that CERN sent sailing toward Italy. Such tightening removed some uncertainty in the neutrinos' speed. The detector still saw neutrinos moving faster than light.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
