Scientists study those vaccinated more than 60 years ago versus one year ago
Oregon Health & Science University researchers are studying the effectiveness of the smallpox vaccine in patients who received inoculations decades ago compared with those vaccinated more recently. The universal belief has been that smallpox vaccinations provide protection for only three to five years. Until now scientists and physicians assumed that anyone vaccinated more than five years ago had little to no protection left. However, researchers at the OHSU Vaccine and Gene Therapy Institute believe that conventional thinking may not be true. To test their theories, scientists are studying how much protection the smallpox vaccination provides 67 years later versus just a year ago. This information may provide a more accurate way of estimating the spread of a potential smallpox outbreak, because nearly 95 percent of Americans older than 35 were vaccinated, and many may still have strong immunity against smallpox.
"I’ve been intrigued about immunological memory for more than a decade. It’s exciting to be able to apply this interest to something that’s relevant to our community right now," said Mark Slifka, Ph.D., assistant professor of molecular microbiology and immunology in the OHSU School of Medicine "We know that people who contract yellow fever, polio, measles or mumps gain a lifelong immunity to those diseases. Now we want to see if this is universally true for other viruses, such as vaccinia, the virus used for immunizing against smallpox."

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
