We have discovered legions of strange particles that seem to only have a ghostly existence inside materials. Even so, they ...

Some faint stars may not burn with fusion but with dark matter itself. These "dark dwarfs" could be the long-awaited clue to ...

Among the most well-known dark matter candidates are the Weakly Interacting Massive Particles (WIMPs)—very massive particles that interact very weakly with ordinary matter: they pass through ...

To help understand air pollution health effects, researchers at Washington University in St. Louis quantify how the amount of submicron particles in the air has changed over the past 25 years.
