T2K Results Restrict Possible Values of Neutrino CP Phase – Published in Nature, the results are a major step forward in the study of difference between matter and antimatter –
The T2K Collaboration has published new results showing the strongest constraint yet on the parameter that governs the breaking of the symmetry between matter and antimatter in neutrino oscillations. Using beams of muon neutrinos and muon antineutrinos, T2K has studied how these particles and antiparticles transition into electron neutrinos and electron antineutrinos, respectively.
From Tokyo Skytree's observatory, researchers prove time passes faster at a high altitude

A Japanese team of researchers has shown that time at Tokyo Skytree’s observatory — around 450 meters above sea level — passes four nanoseconds faster per day than at near ground level.

The finding, based on extremely precise “optical lattice clocks” that only go out of synch by one second every 16 billion years, proves Albert Einstein’s general theory of relativity, which predicts that clocks in a strong gravitational field will tick slower than those in a field with weaker gravity.
