A new generation of remotely operated vehicle (ROV) capable of routine operation to depths of 6,500 meters (21,320 feet) and communicating its data back to shore via the Internet has been developed by the Woods Hole Oceanographic Institution (WHOI). The vehicle, JASON II, recently completed its first science cruise off the coast of Washington and Oregon and is currently at sea in the Pacific working off the coast of Hawaii.
The $2.5 million project to build JASON II and upgrade its companion vehicles, the imaging system Argo II and the DSL-120 side scan sonar system, began in 2000. All three systems, designed and built by WHOIs Deep Submergence Laboratory, are part of the U.S. National Deep Submergence Facility operated by WHOI for the U.S. ocean sciences community. The facility, the only one in the nation, includes the three-person submersible Alvin as well as the tethered vehicles and provides scientific access to the deep sea for researchers from many disciplines, including biology, geology, and chemistry.

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...
