Over the past 30 years, magnetic resonance imaging has evolved into one of the most important imaging procedures in medical diagnostics. With a new approach based on the use of polarized gases and dissolved substances, it will in future be possible to produce even better quality images of the inside of the human body.

At the same time, it is still necessary to overcome various obstacles before practical implementation can be considered. Except in the case of helium, it is not possible to maintain hyperpolarization over relevant periods. "This means we have to abbreviate the processes of polarization, administration, and detection so they can all be performed in no more than a minute at most," states Heil. Moreover, getting the hyperpolarized substances into the bloodstream without harming the body is difficult. In an attempt to resolve this problem, the research team is working with membranes, such as those used in heart-lung machines or for dialysis. "We also need to separate the reaction chamber from the treatment room," explains Dr. Peter Blümler, who is focusing on this aspect. "Perhaps we will also need several membranes to ensure that only the correct substances enter the blood." However, it seems that a solution to another problem may have already been found. While the polarization of helium or xenon can be achieved with lasers, Dr. Kerstin Münnemann of the Max Planck Institute for Polymer Research has shown in her widely acclaimed work that it is possible to induce magnetic polarization in other substances by means of reaction with parahydrogen. The three scientists intend to combine their expertise to create novel diagnostic procedures at the point where physics, chemistry, and medicine intersect.

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

The world's first electrical car and passenger ferry powered by batteries has entered service in Norway. The ferry only uses 150 kWh per route, which...
On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.
RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...
Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.
To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
