It is commonly assumed that tiny particles just go with the flow as they make their way through soil, biological tissue, and ...

Heavy particles as probes Heavy quarks are like tiny sensors. Being so massive, they are produced just after the initial nuclear collision and move more slowly, thus interacting differently with the ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that particles of matter emerging from energetic subatomic smashups retain a key ...

A new study shows that some of the largest and most powerful stars in the universe are producing incredibly tiny particles of carbon dust—material that could one day help form new planets. The ...

Physicists working at the CERN particle physics lab said they detected a slight but significant difference in how particles of matter and antimatter decay. By Kenneth Chang Understanding why matter ...

Stony Brook University physicists Gabor David and Axel Drees sketch out how a signal of jet energy loss in deuteron-gold collisions at the Relativistic Heavy Ion Collider (RHIC) supports the case that ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

A window into how visible matter emerges from the "nothing" of vacuum has been opened by physicists at the Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) in New York. The ...

Air pollution causes health problems and is attributable to some 50,000 annual deaths in the United States, but not all air pollutants pack the same punch. Scientists have tracked the scope of “PM 2.5 ...
