A newly developed, magnetic resonance (MR)-compatible incubator allows radiologists to safely and efficiently obtain quality diagnostic images of sick infants, according to a study appearing in the May issue of the journal Radiology.
"MR imaging is the most desirable imaging test for many newborns because there is no exposure to radiation," said the studys lead author, Stefan Blüml, Ph.D., associate professor at The Saban Research Institute at Childrens Hospital Los Angeles, and the department of radiology, University of Southern California (USC) Keck School of Medicine. "However, many sick newborns cannot be studied by MR, even when clinically indicated, because of concerns for their safety during transport and during the procedure."
Logistical challenges in providing good diagnostic imaging of newborns are considerable and include monitoring circulation and maintaining constant control of temperature, airflow and humidity. Consequently, few newborns are examined with MR imaging, which is, for many indications, the most accurate non-invasive diagnostic test. Unlike radiography (x-rays) and computed tomography (CT), MR imaging carries no radiation risk.

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...
