Women with atrial fibrillation who are not on anticoagulant therapy have a higher rate of ischemic stroke and face a higher absolute risk for stroke than do men with the condition, according to a joint study by researchers at the University of California, San Francisco, Massachusetts General Hospital, the Division of Research at Kaiser Permanente and Boston University School of Medicine.
Using a sample of 13,559 patients with atrial fibrillation, or rapid irregular contractions of the heart, researchers compared the rates of ischemic stroke between men and women and examined the efficacy and complications associated with a common blood thinner, Warfarin. Their findings are being reported in the September 20 issue of Circulation.
Warfarin is well known to be effective in reducing the risk of stroke in persons with atrial fibrillation; however prior studies have provided conflicting evidence about whether women with atrial fibrillation have a higher risk for stroke than men when not taking blood thinners. "The research from this study clearly shows that gender plays a role in ischemic stroke risk and occurrence," said lead author Margaret Fang, MD, MPH, assistant adjunct professor of medicine, and hospitalist at UCSF Medical Center.

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.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.

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...
