Studies that explore how the denser sections of atoms, known as atomic nuclei, interact with neutrons (i.e., particles with no electric charge) can have valuable implications both for the understanding of these atoms' underlying physics and for the development of...

AMoRE experiment sets new limits on neutrinoless double beta decay of ¹⁰⁰Mo
In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as neutrinoless double beta (0νββ) decay. This is a rare process that entails the simultaneous decay of two neutrons in a nucleus into two protons,...
Thermomajorization theory provides new framework for quantifying mysterious Mpemba effect
The Mpemba effect is an intriguing physical phenomenon that causes some systems to cool faster when they are hot than when they are warm or colder. This effect was observed in various systems, including water, which sometimes freezes faster when it is hot than when it...
Optimal brain processing requires balance between excitatory and inhibitory neurons, study suggests
The brain's ability to process information is known to be supported by intricate connections between different neuron populations. A key objective of neuroscience research has been to delineate the processes via which these connections influence information processing.
First dark matter search using WINERED spectrograph sets new lifetime constraints
Dark matter is an elusive type of matter that does not emit, absorb or reflect light and is thus impossible to detect using conventional techniques employed in particle physics. In recent years, groups of physicists worldwide have been trying to observe this matter...
Hypercharge breaking scenarios could explain the baryon asymmetry of the universe
The Standard Model (SM), the main physics framework describing elementary particles and the forces driving them, outlines key patterns in physical interactions referred to as gauge symmetries. One of the symmetries it describes is the so-called U(1)Y hypercharge:...
Study unveils new extrusion-induced instabilities in viscoelastic materials
Soft viscoelastic solids are flexible materials that can return to their original shape after being stretched. Due to the unique properties driving their deformation, these materials can sometimes behave and change shape in unexpected ways.
The ALPHA experiment moves towards the increasingly precise study of antihydrogen
Antimatter is a fascinating kind of matter made up of antiparticles, which have a mass equivalent to that of their normal matter counterparts, yet they exhibit an opposite charge and distinct quantum properties.
NEON experiment shares results from first direct search for light dark matter
Detecting dark matter, the elusive type of matter predicted to account for most of the universe's mass, has so far proved to be very challenging. While physicists have not yet been able to determine what exactly this matter consists of, various large-scale experiments...
Nickel-58 nucleus may host elusive toroidal dipole excitations
Dipole toroidal modes are a unique set of excitations that are predicted to occur in various physical systems, ranging from atomic nuclei to metamaterials. What characterizes these excitations, or modes, is a toroidal distribution of currents, which results in the...
