Study results show smallpox death toll may be lower than expected in the event of an outbreak and one vaccination may be as effective as many
Final results of a smallpox vaccine study conducted by researchers at Oregon Health & Science University show Americas preparedness for a smallpox outbreak may be greater than initially thought. The research shows 90 percent of those vaccinated 25 to 75 years ago maintain a substantial level of immunity. In addition, researchers concluded that in the long term, repeated vaccinations do not result in a higher level of disease protection. The research project is the largest of its kind ever conducted. The study is printed in the September edition of Nature Medicine.
"Previously, it had been widely accepted that smallpox virus effectiveness lasts only 3 to 5 years," said study principal investigator Mark Slifka, Ph.D., a scientist at the OHSU Vaccine and Gene Therapy Institute. "This research shows that significant immunity levels last for many decades, perhaps throughout a persons entire life. It also shows that repeated vaccinations provide a short-term boost in immunity but, over time, do not create a sustained higher level of protection compared to those persons vaccinated only once."

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
