Afghanistan's natural resources include significant deposits of metals such as gold, silver, copper and zinc; precious and semi-precious stones including lapis, emerald and azure; and coal, natural gas and oil. Accurate geological surveys of the country's mineral resources are crucial to locating deposits and advising potential investors, but the AGS has seen decades of decay and neglect.
Michael Watts, an analytical chemist with the British Geological Survey, is deputy leader of a team that has just left for Afghanistan to install a geochemistry laboratory. ‘We have to take a very pragmatic, low-tech approach,’ Watts told Chemistry World magazine. ‘We are establishing a very basic infrastructure.’ The main piece of equipment for the laboratory will be a spectrophotometer, used to test water for the presence of zinc, nickel and copper.
If the AGS can start to function efficiently once again, the future is potentially bright: donors such as the World Bank are waiting in the wings with substantial investment to help develop Afghanistan’s mineral trade.

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...
