Physicians have won the victory over the natural variola virus: it does not exist in nature any longer. Now, it is also necessary to destroy the viruses kept in the laboratory, however, their genetic material should be preserved. Resolution of this task in Russia is funded by the International Science and Technology Center (ISTC).
Specialists of the State Research Center of Virology and Biotechnology “Vector” (Ministry of Health of the Russian Federation) supported by the International Science and Technology Center (ISTC) disassembled into fragments complete genomes of 8 cultures of natural variola viruses. In such a form, virus’ genome can be kept for a very long time and used for research work without fear that the virus itself will get into disposal of terrorists or will “escape” the laboratory as a result of an accident.
Large-scale actions undertaken by the world community under the aegis of the World Health Organization allowed to fully eliminate natural variola. At present, natural variola viruses are preserved only in collections of two collaborative research centers: in the Center for Disease Control and Prevention (CDC) (Atlanta, USA) and in the State Research Center of Virology and Biotechnology “Vector”. Since 1980, immunization of population against natural variola virus was ceased in all countries, and the amount of people sensitive to this disease is constantly growing. Repositories of viable cultures of the virus are a source of possible biological hazard. Therefore, World Health Organization decided in 1986 that it was necessary to destroy all collections of natural variola virus’ cultures and their DNAs. Extermination is inevitable, but it will be a great loss for virology and medicine. Firstly, functioning and organization of this virus have not been studied in detail, secondly, although nobody falls ill with natural variola now, specialists should have the opportunity to develop contemporary express-diagnostics methods. To continue the research, the Russian scientists had to develop a safe way for preservation of genetic material of this virus.

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...
