New source of global nitrogen discovered

For centuries, the prevailing science has indicated that all of the nitrogen on Earth available to plants comes from the atmosphere. But a study from the University of California, Davis, indicates that more than a quarter ...

A stepping stone for measuring quantum gravity

A group of theoretical physicists, including two physicists from the University of Groningen, have proposed a 'table-top' device that could measure gravity waves. However, their actual aim is to answer one of the biggest ...

Breaking the symmetry in the quantum realm

For the first time, researchers have observed a break in a single quantum system. The observation—and how they made the observation—has potential implications for physics beyond the standard understanding of how quantum ...
