Painting pictures with atom waves

Article Abstract:

Japanese researchers got atoms to behave like light waves for the purpose of etching microscopic patterns. Neon atoms were passed through a membrane with a transcription a hologram. A coherent atom wave diffused through the membrane, and atoms made the desired pattern on an fluorescent detector.

Dust grains bring long-lost stars into the laboratory

Article Abstract:

Analyses of tiny grains of long-dead stars found in meteorites are providing new data on the age of the Milky Way and of the universe. The isotopic composition of each grain reveals the type of star in which it formed.
