It is hard to overstate the scale of the humanitarian emergency unfolding in Sudans strife-torn Darfur region: by current estimates there are 1.45 million people displaced from their homes across an area the size of France. However, images from space are assisting aid workers as they cope with the crisis.
An ESA-supported consortium called Respond is supplying Earth Observation-derived maps and other geographical information products direct to users in the field including the German Red Cross (DRK), the United Nations Office for the Coordination of Humanitarian Affairs (UN OCHA) and the German federal disaster relief agency Technisches Hilfswerk (THW).
The Respond team made use of ten different sensors from nine separate spacecraft, including instruments on ESAs Envisat satellite - the Advanced Synthetic Aperture Radar (ASAR) and the Medium Resolution Imaging Spectrometer (MERIS), with imagery delivered in near-real time. "The start of Sudans rainy season in August made a bad situation worse," said Kader Fellah of Strasbourg-based firm SERTIT, which provides Responds rapid mapping capacity jointly with the Centre for Satellite-based Crisis Information (known in its German initials as ZKI) of the German Aerospace Centre (DLR).

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
