In animal studies, researchers at Johns Hopkins have effectively used magnetic resonance imaging (MRI) to measure with 94 percent accuracy the size and amount of heart muscle damaged by a heart attack, known in medical terms as a myocardial infarct, or m.i., for short.
The Hopkins development, if confirmed in further pathology studies in humans, could standardize how physicians currently gauge the severity of a heart attack and a patients chances for recovery. A variety of methods are currently used to determine the size of an infarct by MRI, such as visual cues, but these estimates have been shown in previous studies to overestimate damage by an average of 11 percent.
The researchers, whose findings will be published in the Journal of the American College of Cardiology online Dec. 21, hope to apply this information for determining more accurate dosing regimens for stem cell therapies currently under development, in which upwards of 200 million stem cells are injected directly into the damaged heart muscle.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
