New results from the STAR detector at the Relativistic Heavy Ion Collider (RHIC) suggest that gluons, the glue-like 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.
The issue of whether Indigenous communities support or oppose energy or infrastructure projects is increasingly making headlines, both in Canada and elsewhere. A case study from the Philippines exemplifies the complex realities on the ground, well beyond a binary yes-or-no divide.
Billions of federal dollars are invested in public transportation each year, but those investments may yield greater ridership gains in smaller and midsize transit systems, particularly in the South and West, than in the nation's largest metropolitan areas, according to a new study co-authored by...
Researchers at Monash University have predicted a new type of quantum matter that challenges decades of thinking about how ultracold particles behave. The paper, "Quantum droplets in a resonant Bose-Fermi mixture," is published in Physical Review Letters.
A composite image of data from the Hubble Space Telescope, the Kitt Peak four-meter telescope and MOTHRA reveal the Helix Nebula. We can see the bow shocks, particularly on the left.
