Weak equivalence principle violated in gravitational waves

The Weak equivalence principle (WEP) is a key aspect of classical physics. It states that when particles are in freefall, the trajectories they follow are entirely independent of their masses. However, it is not yet clear ...

A question of quantum reality

Physicist Reinhold Bertlmann of the University of Vienna, Austria has published a review of the work of his late long-term collaborator John Stewart Bell of CERN, Geneva in EPJ H. This review, "Real or Not Real: that is the ...

The psychology of fake news

The brain can be untrustworthy when it comes to deciphering fake news, and especially when headlines are repeated, presented with photos, or generally easy to imagine, experts from The Australia National University (ANU) ...

Healing an Achilles' heel of quantum entanglement

Louisiana State University Associate Professor of Physics Mark M. Wilde and his collaborator have solved a 20-year-old problem in quantum information theory on how to calculate entanglement cost—a way to measure entanglement—in ...

Fishing for a theory of emergent behavior

Researchers at the University of Tsukuba used advanced metrics from information theory to describe the collective behavior of small schools of ayu fish. They found that the overall dynamics were noticeably different for groups ...
