In this study the possibilities of the North American oak (Quercus rubra L.) as an afforestation alternative in the Basque Country Autonomous Community were investigated. The aim was to expand the range of possibilities in forestry production, avoiding monospecific plantations but, at the same time, meeting the needs of the current economy on the basis of sustainable development.
The study centred on 6 plantations of various ages in Bizkaia, firstly studying the wealth of epigeous fungi (based on sporocarps) as well as of hypogeous fungi (as ectomycorrhizals). Over a three-year period of sampling, 111 high-value species of macromycetes were studied; being grouped in 7 orders (Agaricales 60%, Russulas 18%, Boletals 14%, Polyporals 4%, Pezizales 2%, Cantharelles 1% and Phalalles 1%). The mature plantations, apart from showing a greater specific wealth, have proved to be more homogenous amongst each other than the non-mature ones. As regards ectomycorrhizals, 90 morphotypes have been described: 6 of these were identified at a species level; 1 was ascribed to a hitherto unknown morphotype and 7 to a genus. As regards the number of morphotypes, no differences were observed between mature and non-mature plantations. Winter turned out to be the season with the greatest number of morphotypes and of ectomycorrhizals types, followed by the autumn.
Also, the infective potential of the soils of the plantations was evaluated and it was observed that plantlings of 1 or 2 saps can be mycorrhized by the inoculum present in both mature and non-mature plantations.

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.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
