When a star gets too close to a black hole, it causes sparks to fly. And in theory, neutrinos, which are subatomic particles, might do the same thing as well. When a supermassive black hole devours a wandering star, it creates a brilliant light show as the star is torn

The possibility that neutrinos may be their own antiparticles, unique among the known fundamental particles, arises from the symmetric theory of fermions proposed by Ettore Majorana in 19371. Given the profound consequences of such Majorana neutrinos, among which is a potential explanation for the matter–antimatter asymmetry of the universe via

The IceCube Neutrino Observatory (IceCube) is a research facility at the South Pole in Antarctica. IceCube is maintained and operated by the Wisconsin IceCube Particle Astrophysics Center (WIPAC) with funding from the U.S. National Science Foundation (NSF) and other international funders. Scientific analysis is performed around the world by members

We live in the “Homo Electricus” era, in which a world without electricity is unthinkable. Almost every aspect of daily life relies on the energy provided by the wall socket. Another fascinating aspect is the science within: researchers have been working on a groundbreaking new technology that will revolutionize the

A unique characteristic of exponentially growing scattering amplitude arises in an anomalous Abelian effective field theory when an extremely light Dirac neutrino mass is introduced to break the symmetry. We show that the low energy effective Lagrangian can be made explicitly gauge invariant with the help of a nonlinear representation

Life on Earth will cease to exist without electrical energy, and a breakthrough kind of renewable energy that does not require batteries is emerging. In the not-too-distant future, neutrinovoltaic devices will power every electrical item on the planet, ushering in the age of „perfect electricity,“ according to Neutrino Energy Group

In the run-up to the announcement of the 2021 Nobel Prize for Physics on 5 October, we’re running a series of blog posts looking at previous recipients and what they did after their Nobel prize-winning work. Michael Banks talks to neutrino pioneer Takaaki Kajita about the move into gravitational-wave research.

The most generally debated topic in the present news, in light of recent changes in the energy supply sector, is the high gas price, which has resulted in steep increases in power and heating bills, as well as unending disputes over who is to blame and what should be done

Greta Thunberg, then 15 years old, began protesting for emission reduction three years ago. She is currently cited in international media as stating at the UN Climate Summit (COP26) this year that leaders of state and administration should cease making hollow promises to the youth of today Her comment follows

Supermassive black holes, even if they are not so active, can be major factories of high-energy cosmic particles in the universe, according to a new model proposed by an international research team including Penn State scientists. A paper describing the model that may explain the mysterious connection between observed gamma
