NYU School of Medicine scientists have created the first active vaccine that can significantly delay and possibly prevent the onset of a brain disease in mice that is similar to mad cow disease. The new findings, published online this week in the journal Neuroscience, could provide a platform for the development of a vaccine to prevent a group of fatal brain diseases caused by unusual infectious particles called prions.
Although no cure for these diseases -- which include scrapie, mad cow disease, and chronic wasting disease -- is on the horizon, many research groups in both the United States and Europe are working on prion vaccines. But the NYU study is important because it breaks new ground in demonstrating that active immunization can protect a significant percentage of animals from developing symptoms of prion disease, explains Thomas Wisniewski, M.D., Professor of Neurology, Pathology, and Psychiatry, and the lead author of the study.
The vaccines that provide active immunization are made, in part, from proteins found on disease-causing organisms. In response to these proteins, the animal’s immune system produces antibodies that will destroy them any time they appear in the body. Most vaccines in use today provide such active immunization.

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...
