Periodic collisions between the moon Prometheus and Saturn's F ring
Article Abstract:
Prometheus' lag behind its expected position may be due to collisions with objects in Saturn's F ring. These collisions also imply that the mass of the F ring is probably less than 25% that of Prometheus. It has been discovered that the moons Prometheus and Pandora are orbiting on either side of the F ring, partially explaining some of its observed features. The dynamical evolution of the entire Prometheus-F ring-Pandora system is modeled to show that Prometheus may have encountered the core of the F ring in 1994 and that it may still be entering parts of the ring once for every orbit.

Collisions between science and media
Article Abstract:
Premature publication of scientific results can cause conflicts between scientists and journalists, and is against the interests of public. Before of the release of any scientific information, a thorough analysis of the scientific comments at peer level involving other scientists and journalists is necessary to avoid publication of wrong conclusions. Press release with an embargo helps the quality of coverage of science in the media, and serves the interests of scientists, journalists and the public.

Star formation triggered by galaxy collisions
Article Abstract:
Galaxy evolution is influenced by collisions between galaxies, as is becoming increasingly apparent. Major star-formation events are triggered during the ultimate phases of collisions between galaxies, and they power ultraluminous infrared galaxies. Star formation occurs immediately prior to the formation of single elliptical galaxies. Observation using the Hubble Space Telescope and ground-based telescopes may shed light on the role of galaxy merging during the infancy of the Universe.
