Neutrinos: 'Ghost Particles' Can Interact With Light After All

Amazing stuff! This could be a major discovery, but it is highly theoretical.

"... According to new calculations, interactions between neutrinos and photons can take place in powerful magnetic fields that can be found in the plasma wrapped around stars.
It's a discovery that could help us understand why the Sun's atmosphere is so much hotter than its surface ..."

"... “Our results are important for understanding the quantum mechanical interactions of some of the most fundamental particles of matter,” ... “They may also help reveal details of currently poorly understood phenomena in the sun and other stars.” ...
“We have revealed, however, how neutrinos and photons can be induced to interact in the uniform magnetic fields of the extremely large scale—as large as 103 km—found in the form of matter known as plasma, which occurs around stars.” ..."

From the abstract (a very short one):

"The effective interaction of a neutrino with a photon in magnetized plasma is obtained from a strong field expansion in the electroweak standard model. The interaction is expressed by a Chern–Simons form of the neutrino current and the electromagnetic vector potential of the coupling strength proportional to 

. The derivation of the interaction Lagrangian and its properties are presented."

New insights into neutrino interactions (primary news source) Elusive fundamental particles called neutrinos are predicted to interact unexpectedly with photons under extreme conditions.

The first use of a hydrogen bubble chamber to detect neutrinos, on November 13, 1970. A neutrino hit a proton in a hydrogen atom. The collision occurred at the point where three tracks emanate on the right of the photograph.
