Magnetic resonance imaging (MRI) of the heart and lungs is a valuable diagnostic tool in the medical industry, but the detailed images it produces are often marred by artefacts (unwanted signals) created by the motion of cardiac and respiratory cycles.
A team of inventors at Oxford University has now developed a method of suppressing MRI artefacts to a negligible level. This has potential to allow more precise conclusions to be made from a small number of experimental trials, with obvious potential within the pharmaceutical industry, both to accelerate research work and to improve the robustness and quality of screening data upon which key project decisions can be made.
Cardiac and thoracic MRI of small animals, such as mice, requires high spatial resolution in order to resolve fine detail. However, MRI is extremely sensitive to motion from the cardiac and respiratory cycles, which cause severe image artefacts. To reduce these artefacts, synchronisation (gating) to these physiological cycles is required.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
