Radar imagery of underground water
Caring for more than 180,000 Sudanese refugees gathered in the desert landscape of eastern Chad, the United Nations High Commissioner for Refugees has begun using satellite data to identify hidden water resources and site new camps.
By permission of the Chadian government, there are currently nine United Nations High Commissioner for Refugees (UNHCR) camps in place. UNHCR has transferred the vast majority of the refugees from the volatile border to the camps. Thousands more have come on their own from the border, further straining already scarce resources. And concerns remain high that more refugees could still flee from Darfur.
A huge volume of people has to be kept supplied with food, water and basic necessities in this remote region, linked by inadequate roads made worse by the onset of the rainy season. The greatest single need is water. UNHCR standards call for 15 litres of water per person per day, but some camps in eastern Chad are still below this minimum requirement.

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.

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...
