This is a major challenge that CIRAD is keen to take up in order to stimulate economic development in tropical zones with low rainfall. Breeding resistant cotton varieties would discourage African farmers from abandoning their land in the event of drought.
For ten years, now, CIRAD had been studying cotton growing in the arid lands of sub-Saharan Africa. Its researchers are working to breed drought-resistant planting material. However, "this is a slow business, involving numerous trials", as Bernard Hau, from CIRAD’s Annual Crops Department’s "Cotton Farming Systems" Research Unit points out.
The Israeli biotechnology firm Evogene has isolated gene/promoter combinations of agronomic interest in tomato that are involved in resistance to drought and to salt water. The idea is to apply the technique to cotton, using bioinformatic analysis tools that could lead to the creation of new varieties.
The Cottonstress project has been granted funding from the Agence nationale de la recherche, which should allow it to employ two researchers. Work is due to begin in May, at INRA’s Versailles laboratories.

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,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

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...
