Recent measurements of particles called B mesons deviate from predictions. Alone, each oddity looks like a fluke, but their collective drift is more suggestive.
The difficult-to-detect neutrino seems to undergo a strange identity-flipping process, and if this reaction occurs differently between neutrinos and antineutrinos, then it could help physicists explain why matter dominates over antimatter.
Just after 2:30 p.m. on Sept. 30, Fermilab accelerator pioneer Helen Edwards prepared to stop the circulation of subatomic particles in the Tevatron collider for the last time. She was a fitting choice; Edwards and her husband, Don, had led the Tevatron start-up nearly three decades earlier.
Maria Goeppert Mayer left an indelible stamp on the history of physics. Now the US Postal Service has honored the nuclear physicist with a stamp of her own.
Would you walk 10,000 steps for a piece of glass the size of a deck of cards? What if that piece of glass were part of an astrophysics experiment to warn people about potentially deadly asteroids zooming toward Earth and make a 3D map of the universe?
