Physical symptoms that impact quality of life, such as nausea and shortness of breath, may predict shorter survival for patients with terminal cancer.
A new study published July 26, 2004 in the online edition of CANCER, a peer-reviewed journal of the American Cancer Society, finds a patients symptoms and results of quality of life assessments may provide important clues to an individual patients prognosis. Psychosocial factors, such as anxiety or spiritual distress, did not predict shorter survival.
In order to give the most appropriate treatment options to newly diagnosed cancer patients, physicians often assess a patients health-related quality of life (hrQoL), along with tumor characteristics that predict the aggressiveness of the disease and, ultimately, outcome (i.e., response rate to treatments, overall survival, time to progression, and survival in years). In the field of palliative care, length of survival and quality of life are paramount. Research has demonstrated that clinical factors and tumor characteristics predict survival in terminal cancer patients, but there is limited data on the predictive value of hrQoL measures, such as physical and psychological symptoms. Existing research suggests that physical symptoms, not psychosocial symptoms, predict length of survival. However, the conclusions of these studies are weakened by methodological shortfalls.

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...

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...
