Microarray chips enhance clinical diagnostics
AACHEN, Germany — A laser-based benchtop system fabricates protein microarray chips for use in clinical diagnostics, enabling doctors to identify tumor markers in blood samples and to detect pathogens responsible for infectious diseases. Microarray chips for diagnostic use are produced by depositing small samples of material, biopsied, for example, from a patient's tumor cell, onto a substrate. A small amount of the relevant cell material can be gathered, but this limits the testing that can be carried...
X-ray Facility to Investigate Earth’s Core
GRENOBLE, France, Nov. 15, 2011 — ID24, a new x-ray beamline developed at the European Synchrotron Radiation Facility (ESRF), will explore the last white spot on our globe: the center of Earth. This computer-generated image shows the layers of the Earth: the outer solid crust,...
