*Wolfgang Fink’s research into artificial retinas helps restore some sight in blind patients with age-related macular degeneration or retinitis pigmentosa.*

University of Arizona College of Engineering professor Wolfgang Fink has been elected to the College of Fellows of the American Institute for Medical and Biological Engineering.

Fink is an associate professor in the UA department of electrical and computer engineering, where he is the founding director of the Visual and Autonomous Exploration Systems Research Laboratory and holds the Edward and Maria Keonjian Endowed Chair. Fink also has joint appointments in the departments of biomedical engineering, systems and industrial engineering, and ophthalmology and vision science. (more…)

Probes Suggest Magnetic Bubbles at Solar System Edge

PASADENA, Calif. –– Observations from NASA’s Voyager spacecraft, humanity’s farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.

While using a new computer model to analyze Voyager data, scientists found the sun’s distant magnetic field is made up of bubbles approximately 100 million miles (160 million kilometers) wide. The bubbles are created when magnetic field lines reorganize. The new model suggests the field lines are broken up into self-contained structures disconnected from the solar magnetic field. The findings are described in the June 9 edition of the Astrophysical Journal. (more…)
