A small study published today in the journal Critical Care, reveals that most Intensive Care Unit (ICU) patients who gave their informed consent to take part in a clinical trial remembered having participated in the trial ten days later. But two-thirds of the patients did not remember the purpose and risks of the trial, although they had been given information about them before the trial started.
Catherine Chenaud and colleagues from the University Hospital of Geneva, Switzerland, studied 44 ICU patients who had been selected for a clinical trial on inflammatory responses. The patients were given a 20-minute presentation about the study, its purpose and its risks and were given a leaflet to read, before agreeing to participate in the trial. They were then interviewed ten days later.
Chenaud et al.’ s results show that 35/44 patients remembered having taken part in the trial, but that only 20/44 patients remembered the purpose of the study and only 21/44 patients remembered the study risks. Furthermore, only 14/44 patients remembered both the purpose of the trial and its associated risks. The 14 patients who remembered all aspects of the trial did not differ from other patients, except that they had read the leaflet or had asked at least one question during the presentation, before signing the consent form.
The authors conclude that obtaining informed consent from patients should be a process which is revisited many times, rather than one event at the start of the trial, and that patients should be given information repeatedly during the course of a trial.

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...
