A University of Iowa study suggests that inhibiting a certain protein involved in inflammation might be of therapeutic benefit in organ transplantation, heart attacks and possibly stroke. The study, led by John Engelhardt, Ph.D., UI professor and interim head of anatomy and cell biology, found that blocking the action of this protein can prevent the tissue damage caused by ischemia/reperfusion injury. The study is published in the March 1 issue of the Journal of Clinical Investigation.

Ischemia/reperfusion injury is a common, damaging component of organ transplantation, heart attack, and stroke and is a determinant of organ failure in all cases. In this type of injury, the organ is initially deprived of oxygen-carrying blood (ischemia). During reperfusion (the re-establishment of blood supply), toxins are briefly generated from the oxygen that lead to tissue damage and trigger a potentially detrimental inflammatory response.
Although inflammation is an important bodily response to environmental injuries including bacterial and viral infection as well as ischemia/reperfusion injury, too much inflammation can damage healthy tissue and cause problems.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
