Why is there more matter than antimatter when the properties of the 2 things seem symmetrical? Back in 1964 a particle called the "kaon" was discover that showed the symmetry between the two was not quite perfect and slightly favored matter over antimatter, but kaons are rare and that effect was much too slight to explain why the Big Bang didn't annihilate nearly all the matter in the universe. But now in today's issue of the journal Nature indications of a far larger discrepancy was found between neutrinos and antineutrinos, and matter is winning. More muon neutrinos are oscillating into electron neutrinos than muon antineutrinos are oscillating into electron antineutrinos. The evadens is only 3 sigma so there is still one chance in a thousand it's just a statistical fluke and 5 sigma (one in a million) is required to officially claim a discovery but it's still a pretty big deal.
