The ability of several of Colorados prime ski areas to respond to winter drought is threatened by acidic runoff from abandoned mines, according to researchers at the University of Colorado at Boulder and the Northwest Colorado Council of Governments.
Contamination known as acid-rock drainage enters waterways, such as Summit Countys Snake River, that are used for making artificial snow. When the snow melts, the water can run into streams not previously polluted, further spreading the contamination, said the research team.
CU-Boulders Andrew Todd and Diane McKnight of the Institute of Arctic and Alpine Research and Lane Wyatt of the Northwest Council of Governments describe how past Colorado mining is adversely affecting tourism, now a $9 billion industry. The paper will be published in the Sept. 23rd issue of Eos, published by the American Geophysical Union.

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...
