Large Hadron Collider reveals 'primordial soup' of the early universe was surprisingly soupy
Waiter, there's a quark in my soup!
Scientists smash atoms together to create 'little' big bangs
Recreating the universe’s earliest moments could help us learn more about the elusive quark-gluon plasma.
Physicists create a tiny “Big Bang” with surprisingly small atomic nuclei
Researchers at CERN have created microscopic versions of the early Universe by colliding surprisingly small atomic nuclei at nearly the speed of light. The collisions produced quark-gluon plasma, the ultra-hot matter believed to have filled the cosmos shortly after the Big Bang. Even more intriguingly, the particles left behind reveal the shape of the nuclei that created them, offering a new way to probe both nuclear physics and the Universe’s earliest moments.
Physicists recreated the first millisecond after the Big Bang — and found it was surprisingly soupy
Scientists saw a quark plowing through primordial plasma for the first time, offering a rare look at the first moments after the Big Bang
How a baby business survived China and Canada tariffs
Garett Senez's company Quark Baby is based in Canada and manufactured in China. The tariffs required him to switch up his supply chain to survive.
Physicists discover a hidden gluon structure inside protons that could rewrite textbooks
Physicists may have uncovered a hidden feature inside protons that helps preserve one of matter’s most fundamental properties. RHIC collision data suggest baryon number is carried not simply by three quarks, but by a Y-shaped junction of the gluons connecting them. The finding challenges a decades-old textbook picture and could deepen our understanding of why protons—and ultimately matter itself—remain stable.
Scientists uncover new clue to how protons maintain their identity
New results from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) suggest that gluons, the gluelike particles that hold quarks together inside protons, play a central role in the conservation of baryon number, an essential part of a particle’s quantum identity.

Scientists reveal the hidden force driving the universe’s hottest fluid
When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces. New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion. This acceleration may do far more than move the fluid, potentially changing its temperature-like behavior, influencing particle spins, and even reshaping how matter transitions between fundamental states.
It’s official: scientists aren’t funny. But it doesn’t have to be this way
It’s a world of bottom quarks and arsole compounds – so why is science still so serious? Levity can make it all a lot easier to understand, says science writer Helen Pilcher
CERN Physicists Observe New Exotic Particle
Physicists with the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) have observed the Bc*+ meson, an excited version of the Bc+ meson -- both consist of a charm quark and a bottom antiquark.
Physicists found hidden order in violent proton collisions
Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary particles. Researchers expected this transition to change how disordered the system is, but LHC data tell a different story. A newly improved collision model matches experiments better than older ones and reveals that the “entropy” remains unchanged throughout the process. This unexpected result turns out to be a direct fingerprint of quantum mechanics at work.

A search for one exotic particle uncovered two strange new structures
A search for one mysterious particle unexpectedly revealed evidence for two different structures that may belong to the bizarre family of exotic subatomic particles known as XYZ states. The findings could help physicists uncover new ways that quarks and gluons combine to create matter.
