A 7-month-old child whose first corneal transplant was unsuccessful underwent surgery Monday at the University of Rochester Eye Institute to implant an artificial cornea in an effort to give him sight. He is the youngest patient ever to receive the device.
Lukas Rakowsky of Dupont, Wash., was born in May with a tumor on his left eye. The tumor was successfully removed five weeks after his birth at Madigan Army Medical Center in Ft. Lewis, Wash. Lukas also underwent corneal transplant surgery that same day, in an attempt to help him achieve sight in the eye. The day after the surgery, though, Lukas cornea began to cloud up again, signaling the transplant had been unsuccessful.
His parents, Shana and Peter Rakowsky, were referred to surgeon James Aquavella, M.D., at the University of Rochester Eye Institute. In addition to specializing in traditional cadaveric corneal transplants, Aquavella has been implanting plastic corneal devices since the 1960s. The first procedures were long and tedious, and results were not known for many months. Patients required careful follow-up for the rest of their lives in an attempt to reduce the ever-present danger of serious complications. But there have been great improvements over the past 40 years, he says, making possible new procedures like the one performed on young Lukas.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
