The image shows a section through many variola major viruses, the agents that cause smallpox. The protein coat is labeled in yellow and genetic material is shown in red.
The best approach for averting the deadly spread of smallpox following release of the virus by terrorists may rest with the establishment of a major collaborative research effort to develop new antiviral drugs that would involve the pharmaceutical and biotechnology industries, universities and government agencies, according to a new report from the National Academies.
The report delivers the recommendations of a distinguished panel of researchers who participated in a two-day workshop at the National Academies to promote the application of the latest biological information, technology and experience to the study of smallpox. Howard Hughes Medical Institute investigator Stephen C. Harrison of Harvard Medical School is the lead author of the report, which was published online July 12, 2004, in the early edition of the Proceedings of the National Academy of Sciences.
According to Harrison, two factors loomed large as the scientists considered the dangers of smallpox. First, there is essentially no information about whether stocks of the variola virus, which causes smallpox, exist outside the two known repositories in the United States and Russia. Second, the impact of intentional release of the virus would “probably provoke a global health crisis.” The report states that “the lethality of the disease (up to 40 percent) and its ease of transmissibility place variola virus at the top of the [Centers for Disease Control and Prevention’s] list of high threat (category A) agents.”

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
