conglomeration

That evidence includes tiny chunks of partially charred plants — including charcoal as identified by its microstructure — as well as conglomerations of charcoal and associated minerals embedded within fossilized hunks of Prototaxites fungi.

It looks, in many respects, like a conglomeration R2-D2 from Star Wars, a remote control toy tank, and a hide-a-key rock.

When a bright “pump” laser is shone onto the device, photons from its beam couple with the material to create a conglomeration of quasiparticles known as a Bose-Einstein condensate, a collection of particles that behaves like a single atom.

These groups can grow into ever-larger conglomerations, potentially hundreds of millions strong, that cross continents and destroy crops.
