AIDS researchers have developed a candidate vaccine strategy that, for the first time, demonstrates an ability to elicit antibodies that block the infection of multiple HIV virus strains -- an elusive scientific goal that has been pursued for a decade.
The candidate vaccine - still early in developmental stages at the Institute of Human Virology (IHV) -- is described in a report to appear during the week of Aug. 19-23 in the U.S. Proceedings in the National Academy of Sciences (PNAS). It is authored by Drs. Timothy Fouts, Anthony Devico, and colleagues at the IHV, a center of the University of Maryland Biotechnology Institute and affiliated with the University of Maryland Medical Center, and Dr. Ranajit Pal and colleagues at Advanced BioScience Laboratories, Inc. (ABL) in Kensington, Md.
One of the major challenges in developing an effective AIDS vaccine has long been the fact that the virus that causes AIDS, much like the influenza virus, exists as multiple strains that present many different faces to the immune system, say the authors. The surface of the AIDS virus, HIV, is coated with a protein called gp120 that has chemical features that vary from strain to strain. It has been difficult for researchers to find a single vaccine component that is able to generate antibodies that recognize the many forms of gp120 that exist in nature.

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...
