In response to demand from partners in developing countries, CIRAD is improving its expertise in terms of genetics and innovative citrus varietal improvement strategies. Having realized that they have common objectives, the IVIA "Plant Protection and Biotechnology" and "Genomics" centres and the CIRAD "Genetic Improvement of Vegetatively Propagated Crops" Internal Research Unit have joined forces to boost the efficacy of their research.
The two Spanish and French organizations have been working together for more than 20 years, and as of this summer, two CIRAD researchers, Patrick Ollitrault and Raphäel Morillon* have been assigned for three years to work with IVIA (Instituto Valenciano de Investigaciones Agrarias) teams in Moncada (Spain).
The stakes are high, given that citrus fruits make up the world's largest fruit production sector, with more than 100 million tonnes produced each season, and that the sector is under increasing pressure from emerging and invasive crop diseases, the depletion of water resources and increased salinity. Moreover, consumers are becoming more demanding: they now want small fruits (mandarins, clementines) that are easy to peel and seedless, with good colour.
In view of those constraints, varietal improvement is proving to be a major factor for sustainable citrus fruit growing in both the North and South. French and Spanish teams are working to optimize the existing synergies in the research sector. On the one hand, the aim is to gain a clearer understanding of the existing diversity and the physiological, molecular and genetic factors that determine worthwhile characters, and on the other, to develop innovative varietal creation methods based on biotechnologies.
The IVIA-CIRAD technical platform created in Spain will provide a global role for a European citrus improvement pole open to new Euro-Mediterranean partnerships.

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,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
