Physicists discover inexplicable interactions between particles in the search for dark matter

Deep below the Gran Sasso Mountains in Italy, the world’s most sensitive dark matter experiment has made a surprising discovery. No, it is not dark matter. Instead, the experiment found significantly more particle interaction events than predicted by the standard model of particle physics. Instead of the 232 ± 15 low-energy events expected in the data for a year from …

The hunt for elusive ghost particles in the Antarctic has begun

Unlike light and other forms of radiation generated by these galaxies, a neutrino does not lose its energy when it moves through space because it does not interact with other matter. This makes neutrinos extremely difficult to spot, but it also makes them the best way to study exotic celestial objects like quasars and blazars that are billions of light …

Gold, vanadium and europium reveal the existence of mysterious particles

An international research group published a study in National Academy of Sciences procedure where they present evidence of the existence of Majorana fermions – particles that are believed to be their own antiparticles – on the surface of a gold object. According to the scientists, this is an important step in isolating the particles as stable, fail-safe quantum bits or …

Physicists at MIT shave the estimate of the mass of neutrino ghost particles in half

An international team of scientists, including researchers at MIT has come closer to establishing the mass of the elusive neutrino. These ghostly particles penetrate the universe and are still considered almost massless. They flow through our bodies millions of times and hardly leave any physical traces. The researchers have determined that the mass of the neutrino should not be more …

Multidecadal increase of plastic particles in coastal ocean sediments

Abstract We analyzed coastal sediments of the Santa Barbara Basin, California, for historical changes in microplastic deposition with a box core that extended over the years 1834-2009. The sediment was visually sorted by plastic and a subset confirmed as plastic polymers by FTIR spectroscopy (Fourier transform infrared spectroscopy). After correcting contaminants introduced during sample processing, we noted an exponential increase …

A new experiment restricts possible properties of dark energy particles

A simulation of a galaxy that forms under a modified theory of gravitation with chameleons. Graphic: Christian Arnold / Baojiu Li / Durham University (Phys.org) An experiment in the UK failed to find any evidence for a particle that would account for most of the bulk of the universe. But the search is not over yet. When cosmologists observe how …

Plastic particles falling out of sky with snow in the Arctic

Media playback is not supported on your device. Media Title The locals are & # 39; sad & # 39; about the changes in the Arctic that you have seen. Even in the Arctic, microscopic plastic particles fall from the sky with snow, a study has found. The scientists were shocked by the sheer number of particles found: more than …

Stanford physicists count sound particles with the quantum microphone

IMAGE: Artistic representation of a series of nanomechanical resonators designed to generate and trap sound particles or phonons. The mechanical movements of the captured phonons are controlled by a qubit detector … view more Credit: Wentao Jiang The physicists of Stanford have developed a sensitive "quantum microphone" that can measure individual sound particles, called phonons. The journal Nature could eventually …
