#Neurodegenerative #diseases represent one of the greatest challenges of our #aging society. Researchers decode a puzzling movement disorder

Neurodegenerative diseases represent one of the greatest challenges of our aging society. However, investigation into these diseases is made particularly difficult due to the limited availability of human brain tissue. Scientists from the Life & Brain Research Center and Neurology Clinic of Bonn University have now taken a roundabout path: They reprogrammed skin cells from patients with a hereditary movement disorder into so-called induced pluripotent stem cells (iPS cells) and obtained functional nerve cells from them. They subsequently decoded how the disease arises. Their results have now been published in the specialist periodical ”Nature.” Continue reading

#Intel copy protection circumvented Checkmate! #RUB researchers outsmart #copy #protection #HDCP

For over a decade, Intel’s widely used copy protection HDCP has been trusted by the media industry, which carries out business in high-resolution digital video and audio content worth thousands of millions. Researchers from the working group on secure hardware led by Prof. Dr.-Ing. Tim Güneysu of the Ruhr-Universität Bochum (RUB) were able to checkmate the protection system of an entire industry with relatively little effort using a so-called “man-in-the-middle” attack.

  • Checkmate!
  • RUB researchers outsmart HDCP
  • “Man-in-the-Middle” attack: Intel copy protection circumvented Continue reading

Astronomers at the Max Planck Institute for Astronomy have, for the first time, measured the alignment of magnetic fields in gigantic clouds of gas and dust in a distant galaxy. Their results suggest that such magnetic fields play a key role in channeling matter to form denser clouds, and thus in setting the stage for the birth of new stars. The work will be published in the November 24 edition of the journal Nature (online version: November 16). Continue reading

Successful combination: #virtual screening and #cell culture research- #Interferon #inhibitor discovered

Interferon alpha plays a central role in severe autoimmune disorders. Inhibitors are not available to date. In collaboration with researchers of the ETH Zurich, Switzerland, scientists at the Paul-Ehrlich-Institut have now succeeded in identifying a substance that inhibits interferon alpha release. Their innovative research approach may not only be of significance for the search of an active substance as such but also for the rapid identification of inhibitors of important protein-protein interactions. The journal “Angewandte Chemie” (Applied Chemistry) reports on the research results as an ‘epub ahead of print’(Hot Paper; DOI: 10.1002/anie.201105901) Continue reading
