ALICE Detects Gluon Saturation Clues Inside Nuclei

CERN’s ALICE experiment used incoherent J/ψ photonuclear production to probe local gluon density fluctuations inside lead nuclei, scanning with momentum transfer to resolutions from 0.6 to 0.2 femtometers. The data show a suppression of J/ψ production at the smallest scales with about 3-sigma significance, challenging traditional nuclear shadowing and aligning with the gluon-saturation picture predicted by quantum chromodynamics, revealing densely packed gluon states inside nuclei.

Nine Costly Science Endeavors That Pushed Humanity’s Knowledge Frontiers

The article catalogs nine of the costliest science projects ever undertaken—ISS, Apollo, Large Hadron Collider, Human Genome Project, Curiosity rover, Skylab, Manhattan Project, NEPTUNE, and the Very Large Array—outlining their price tags, aims, and outcomes, and noting their lasting impact and ongoing upgrades or decommissioning as science’s big bets continue to drive discovery.

Giant 43-Foot Beam Makes 4,850-Foot Descent for DUNE's Underground Neutrino Lab

Crews are lowering 10 million pounds of steel into a former South Dakota gold mine for the Deep Underground Neutrino Experiment (DUNE). A 43-foot beam weighing about 15,890 pounds travels upright in a 4.5-foot-wide cage down the Ross Shaft 4,850 feet to form the two massive cryostats that will house 17,000 tons of liquid argon each. With more than 2,100 components needing to fit through the narrow shaft, the descent—done dozens of times this summer—is a critical, tightly choreographed step toward first neutrinos in 2031.

India’s CERN Partnership Drives Dark Matter Quest and Higgs Legacy

India’s six-decade partnership with CERN puts it at the center of the LHC upgrade and the global hunt for dark matter, with Indian labs contributing to magnet systems, cryogenics, detectors and high-performance computing that underpinned the Higgs boson discovery and will push physics beyond the Standard Model as CERN restarts after a $1.5B upgrade in 2030.

HiLumi Era Begins: LHC Upgrades Set Stage for Tenfold Leap in Physics

After 18 years of discoveries, CERN’s Large Hadron Collider enters Long Shutdown 3 to be upgraded into the High-Luminosity LHC (HiLumi LHC). The upgrade will boost luminosity by about ten times, enabling more detailed data on the Higgs boson and other subatomic phenomena. The renovation includes major overhauls to magnets and infrastructure, with a gradual restart beginning in 2028 and full operation by 2030, marking a new era in particle physics research.

CERN to upgrade the LHC to HiLumi, boosting collisions by about 10x through 2030

The Large Hadron Collider at CERN has entered a four-year Long Shutdown 3 to upgrade into the High-Luminosity LHC, which will raise collision rates by about tenfold and enable roughly 380 million Higgs bosons over its lifetime. The upgrade, which involves replacing thousands of magnets and other components, aims to deliver a much larger data set to probe the Higgs, dark matter, and the early universe. Operations are slated to resume in 2030 and continue into the 2040s, after which a new, higher-energy accelerator may replace it.

Four-Dimensional Ghost Unmasked in CERN's SPS

Physicists at CERN traced a time-evolving resonance inside the Super Proton Synchrotron (SPS) that quietly degrades particle beams. Using a four-dimensional Poincaré surface-of-section, they map fixed harmonic lines that predict where particles cluster, revealing the hidden ‘ghost’ and offering strategies to dampen its effects and guide the design of future accelerators.

CERN Opens Its KiCad Libraries to Open Source Hardware

CERN has released its extensive KiCad footprints and symbols as open-source in a GitLab repo, currently supporting KiCad 9.x with 10.x compatibility on the horizon, a move that could make CERN footprints a common staple in open hardware projects.

First-ever truck transfer of antiprotons marks step for offsite antimatter research

BASE at CERN achieved a world-first by transporting a portable cryogenic Penning trap containing 92 antiprotons on a truck across CERN’s site, demonstrating feasibility for delivering antimatter to other laboratories for higher-precision measurements outside the main antimatter facility.

LHCb Discovers Xi-cc-plus, a New Two-Charm Baryon

Scientists at CERN's LHCb have identified a new baryon, Xi-cc-plus, composed of two charm quarks and one down quark. Weighing about four times the mass of a proton, it offers a testbed for quantum chromodynamics and the strong force; discovered after 2023 detector upgrades, it is only the second observed baryon with two heavy quarks and has a lifetime up to six times shorter than a similar earlier baryon.

CERN uncovers Xi-cc-plus, a heavy new cousin of the proton after decades-long hunt

British researchers at CERN report the discovery of Xi-cc-plus, a proton-like particle four times heavier than a regular proton, found in data from the upgraded LHCb detector after a 20-year search, promising new insights into the strong force that binds atomic nuclei.

CERN Spots New Double-Charmed Baryon Xi-cc-plus After Upgrades

CERN’s LHCb collaboration announced the discovery of a new baryon called Xi-cc-plus, containing two charm quarks and one down quark, making it the 80th identified particle and the first new one found after the LHCb upgrades completed in 2023. It is heavier than a proton and has a shorter lifetime—about six times shorter than a similar earlier particle—posing detection challenges but providing a test bed for quantum chromodynamics and guiding future collider plans like the Future Circular Collider.

LHCb Finds Proton-Like Baryon With Two Charm Quarks

At CERN, the LHCb collaboration announced the discovery of a proton‑like baryon made of two charm quarks and one down quark, about four times the proton’s mass, observed with 7-sigma significance in Run 3 data; it’s the second baryon with two heavy quarks and a key test for quantum chromodynamics, including a shorter lifetime than the up-quark counterpart, and follows upgrades to the LHCb detector completed in 2023.

CERN Confirms Quark-Gluon Plasma Flows Like a Fluid in the Early Universe

Scientists at CERN used a rare Z-boson–tagged event to observe how a single quark traverses quark-gluon plasma, revealing fluid-like wake patterns that align with hydrodynamic predictions and confirming the primordial plasma behaved as a dense, flowing liquid in the universe’s first microseconds.

Nuclear Deflection Could Work on Metal-Rich Asteroids, Study Finds

New research shows metal-rich asteroid material can harden and self-damp under intense stress from a nuclear deflection, suggesting larger devices could be used without catastrophic fragmentation and preserving a last-resort option for very large or short-warning threats; NASA/ESA plan to study Apophis in 2029 and researchers will test more asteroid types (e.g., pallasites) to better inform planetary defense and hint at planetary formation insights.
