A galaxy at a redshift z=6.96
Article Abstract:
A spectroscopic redshift of z=6.96 for the galaxy whose spectrum clearly shows Luman-alpha emission at 9,682 angstrom is presented and a demonstration that the galaxy formation was ongoing when the universe was only ~ 6 percent of its present age is presented. The number density of galaxies at z=7 seems to be only 18-36 percent of the density at z=6.6.

The element abundance pattern in a galaxy at z=2.626
Article Abstract:
The element abundances in gas inside high-redshift galaxies is probed and an observation of over 25 elements in a galaxy at red-shift z=2.626, is reported. The detailed abundance patterns suggest that boron is produced through processes that act independently of metallicity.

Uranium gets a reaction
Article Abstract:
The lately developed chemistry of the reactions taking place between uranium and potassium ions is discussed. The findings reveal that the new approach can be easily used for the development of many more uranium compounds.
