CLOUD experiment uncovers a major new source of marine aerosol particles
In a paper published today in the journal Nature, the CLOUD Collaboration at CERN reports that natural emissions from phytoplankton are producing far more aerosol particles than previously thought, changing our understanding of aerosols and clouds in pristine climates from before the industrial era and after the fossil fuel era. Cloud droplets form on aerosol

Getting under the skin of atomic nuclei using antimatter
Researchers at the AEgIS experiment have piloted a new method to delve into the heart of atoms. This proof-of-principle study, recently reported in Physical Review Research, shows how antiprotons – the antimatter counterparts of protons – could be used to probe the outer edges of a wider range of atomic nuclei. And with CERN’s recent

ALPHA measures tiny energy gap in antimatter with improved precision
Researchers at the ALPHA experiment have achieved a hundredfold improvement in their measurement of a feature of the antimatter counterpart of the hydrogen atom. The result, published today in Nature, allows a precise comparison of hydrogen and antihydrogen. In this study, the ALPHA Collaboration measured the ground-state hyperfine splitting of the antihydrogen atom, which comprises

The January/February 2026 issue of the CERN Courier is out
Physicists can be allies, wrote Wassily Kandinsky, “who test matter again and again, who tremble before no problem, and who finally cast doubt on that very matter which was yesterday the foundation of everything, so that the whole universe is shaken.” This edition of CERN Courier offers two examples of physics to shake the universe.
