Might the proton decay in other places or at other times?
Does the proton decay? While this was a famous prediction of Grand Unified Theories (GUTS) developed in the 1970s and 1980s, experimentalists have ruled it out—or rather, put lower limits on its mean lifetime of about 1034 ...
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 ...
Scientists measure the spin-parity of charm baryons for the first time
In a new development at CERN, researchers at the LHCb collaboration have determined the spin-parity of singly heavy charm baryons for the first time, addressing a long-standing mystery in baryon research.
New DESI results strengthen hints that dark energy may evolve
The fate of the universe hinges on the balance between matter and dark energy: the fundamental ingredient that drives its accelerating expansion. New results from the Dark Energy Spectroscopic Instrument (DESI) collaboration ...

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 ...
What's behind the 'pop and slosh' when opening a swing-top bottle of beer?
In a fun experiment, Max Koch, a researcher at the University of Göttingen in Germany—who also happens to be passionate about homebrewing—decided to use a high-speed camera to capture what occurs while opening a swing-top ...
