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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
