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.
The pursuit of dark matter and dark energy is one of the most exciting—and most challenging—areas of science. Now researchers think they’re beginning to close in.
Researchers apply the rules of particle physics to the world of online shopping and recommendation engines, and suggest it may be unwise to rely on popular opinion.
