In 1967, Andrei Sakharov proposed conditions required in the early universe for generating matter and anti-matter at different rates, to explain the abundance of matter in our universe today. Charge-Parity (CP) violating processes are essential under these conditions. Measurements of the CP violation in quarks, first performed in 1964, are too small to explain the difference, and finding other sources of CP violation is an ongoing quest in the physics community. In April 2020, the T2K collaboration published a paper in Nature suggesting large CP violation in the leptonic sector, namely in neutrino oscillations. Some of the researchers involved in the project tell us their story.  Read more

Behind the paper: Serendipitous encounters

If you meet an editor of the Nature journals they will likely assure you that to get published you just need good science. But, the truth is there is some luck involved too – especially for interdisciplinary work. Sometimes the editors accidentally come across gems of papers. Bart Verberck and Liesbeth Venema tell two such stories.  Read more
