Astronomers Uncover Previously Unseen Population of Seven Primitive Galaxies

Using NASA's Hubble Space Telescope, astronomers have uncovered a previously unseen population of seven primitive galaxies that formed more than 13 billion years ago, when the universe was less than 4 percent of its present age. The deepest images to date from Hubble yield the first statistically robust sample of galaxies that tells how abundant they were close to the era when galaxies first formed.

Novel Superconducting Element Holds Potential for Medical Imaging Applications

Scientists from the University of Tübingen, working with colleagues from Tel Aviv University and the University of Kiel have proposed [1] and experimentally demonstrated [2] a new type of superconducting element ¨C named the j - Josephson junction. Implemented in cryogenic devices, this element will make superconducting electronic circuits work practically "by themselves" and improve functionality.
