In Sweden, a form of hemorrhagic fever with renal syndrome called nephropathia epidemica occurs primarily in the northern parts of the country. It is a zoonosis, that is, an infectious disease that is normally transmitted between animals and humans when a bank vole, for instance, releases Puumala hantavirus via its saliva, urine, and feces.
Normally humans become infected by breathing in dust polluted by virus from bank vole secretions or by direct contact with the animal.
It has recently been shown in South America that the Andes hantavirus, which is closely related to the Puumala hantavirus, can in some cases be transmitted among humans. The Umeå team's findings indicate that a possible path of contagion for hantavirus disease might be human saliva.
During last year's outbreak of nephropathia epidemica in northern Sweden, saliva samples were collected from 14 patients in Västerbotten County, and virus RNA was found in the saliva in ten cases. It is not clear whether the virus found in human saliva is capable of infecting another human, but this question is now being studied intensively.
Nephropathia epidemica, is a serious disease, and patients coming to hospitals often have high fevers, headaches, muscle pain, and abdominal pain, and are in generally poor condition. In Sweden some 2,200 cases of nephropathia epidemica were reported in 2007, and more than 800 of them were from Västerbotten County. Up to 30% of those who were diagnosed with nephropathia epidemica wind up in the hospital, and in Västerbotten County two deaths occurred in 2007. In South and North America infections by close relatives of the Puumala hantavirus lead to death in 40% of cases.
The Umeå team consists of Associate Professor Magnus Evander and resident specialist physician and doctoral candidate Lisa Pettersson at the Division for Virology and Assistant Professor Clas Ahlm and Post-Doctoral Fellow Jonas Klingström at the Division for Infectious Diseases, all at the Department of Clinical Microbiology, Umeå University. Other co-authors are Jonas Hardestam and Åke Lundkvist, Swedish Institute for Infectious Disease Control, Stockholm. The findings will soon be published in the journal Emerging Infectious Diseases.

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...
