Researchers say surgery is best care for fastest growing cancer type
In part because the nature of the disease has changed, nearly 50 percent of patients with esophageal cancer that undergo an advanced surgical procedure now survive for five years, not 20 percent as once thought, according to an article published in the April edition of the Journal of the American College of Surgeons. Researchers at the University of Rochester Medical Center contend that earlier diagnoses, more widespread screening and individualized care have made surgery by far the best way to combat esophageal cancer as it is most often diagnosed today.
Whether surgery, chemotherapy, radiation, or some combination of them should be the standard of care has been debated for years. Until recently, surgery has been considered the gold standard, but its role has been questioned by some medical oncologists based on their assumption that surgery comes with a high risk of complications and small chance of survival. In many cases today, oncologists will try chemotherapy and radiation first, completely avoiding surgery. Authors of the current study argue that the information used to make those decisions is dated, and that the surgery is the most effective approach in many patients.

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.
