A team including researchers at the Total Defense Research Institute, NBC Defense, in Umeå, Sweden, and the Department of Molecular Biology, Umeå University, are publishing in this week’s issue of Science new findings that show that the protein Ymt is of crucial importance for the capacity of the plague bacterium to survive and spread the plague via flea vectors. Professor Åke Forsberg and visiting researcher Dr. Peter Cherepanov are studying the properties that enable the plague bacterium Yersinia pestis to cause life-threatening infections in animals and humans. Increased knowledge of the mechanisms that Y. pestis exploits to conquer the body’s immune defense can make it possible to develop new methods of treatment for serious infectious diseases.
Historically, the plague is one of our most feared infectious diseases. During the most wide-spread epidemic in the middle ages, also known as the Black Death, more than 25% of the European population died. Today the disease is not very common, with some 2,000 cases per year. The plague occurs primarily in Africa and Asia, but there are also a few cases in North America every year.
The bacteria are normally spread by fleas, first of all to rodents. Humans can also be infected by fleas. When the disease reaches the lungs of a human, the infection can be spread through the air to other people. The onset of the disease is rapid, with a high temperature and a headache. There is often an enlargement of the lymph glands located near the back of the jaw, which explains why it is also called the bubonic plague. Untreated, the infection quickly reaches the blood, leading to general blood poisoning. Mortality for untreated bubonic plague is over 50%. If the infection is spread by the air to the lungs, the course of the disease is even more rapid, and mortality for untreated lung plague is virtually 100%. The high rate of mortality, together with the rapid progression of the disease, places plague bacteria among those considered for use as a biological weapon.

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.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
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...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
Every three years, the plastics industry gathers at K, the international trade fair for plastics and rubber in Düsseldorf. The Fraunhofer Institute for Laser Technology ILT will also be attending again and presenting many innovative technologies, such as for joining plastics and metals using ultrashort pulse lasers. From October 19 to 26, you can find the Fraunhofer ILT at the joint Fraunhofer booth SC01 in Hall 7.
K is the world’s largest trade fair for the plastics and rubber industry. As in previous years, the organizers are expecting 3,000 exhibitors and more than...
