The Mediterranean fruit fly, Ceratitis capitata, is a world plague which represents one of the most serious problems for agriculture. However, the control methods currently present in the market for this plague are ineffective.
The research group of the Institute of Biotechnology of the University of Granada (Spain) has isolated and identified a stump of the genus Bacillus, extremely toxic for larvae of C. capitata. After subjecting such stump to a specific treatment, protected by a patent, we have managed to increase notably its toxicity against this fly.
According to Dr. Susana Vilchez (hired by the Ramón y Cajal), the Mediterranean fruit fly has a special economic relevance in the Mediterranean countries, like Spain. Given the capacity of the C. capitata to tolerate colder climates than the rest of the species of flies and their wide range of host plants, the C. capitata has been considered as one of the most important species from the point of view of economy. This plague attacks more than 260 species of fruits, flowers or nuts of agricultural fruits and it has been estimated that causes losses assessed in hundreds of millions of dollars annually in the countries where it settles.
As the European legislation is getting increasingly strict with regard to the use of chemical insecticides –the use of malatión is forbidden since June of 2007-, the alternative of biological control is gaining prominence and is becoming a new exploitation field.
In this sense, the results obtained by the scientists from Granada are promising, as at present there is not any bio-insecticide in the market based on bacteria and active against this plague. In addition, this is a new technique for the of the Mediterranean fruit fly, environmentally friendly, non-toxic, easy to produce, and can be supplied by conventional methods.
The researchers maintain that the development of a commercial product based on these bacteria will mean an important advance for the agricultural industry.

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...
