El Capitan Precious Metals, Inc. (OTCBB:ECPN) reports that the Company's metallurgical R&D initiative involving several large composites drill hole samples of the El Capitan deposit have completed key project milestones. The tin collection fusion procedure was performed on two separate drilling composites in late June, and the subsequent electrolytic parting process was concluded in mid-July. The "anode mud" concentrate was collected, dried, and then subjected to both Scanning Electron...

A new technique allows pictures which were later painted over to be revealed once more. An international research team, including members from Delft University of Technology (The Netherlands) and the University of Antwerp (Belgium), has successfully applied this technique for the first time to the painting entitled Patch of Grass by Vincent van Gogh. Behind this painting is a portrait of a woman. It is well-known that Vincent van Gogh often painted over his older works. Experts estimate that...

Researchers at the National Institute of Standards and Technology (NIST) have developed an improved experimental X-ray detector that could pave the way to a new generation of wide-range, high-resolution trace chemical analysis instruments. In a recently published technical paper*, the researchers described how they used improved temperature-sensing and control systems to detect X-rays across a very broad range of energies (6 keV or more), with pinpoint energy resolution (an uncertainty of...

Measurements of the intensity of light at different wavelengths can be made more accurately now, thanks to a new, simple method for correcting common instrument errors. The new method, developed by researchers at the National Institute of Standards and Technology (NIST), will benefit fields such as color measurement, lighting development, remote sensing, biotechnology and astronomy. The NIST method improves the measurement accuracy of spectrometers, devices that measure optical radiation at...

Aiming to nail down whether Mars could have nurtured life in the past, the Mars Science Laboratory will live up to its name, with a state-of-the-art internal chemical and mineralogical laboratory. The rover will pick up rocks, chew, swallow, then analyze the minerals in detail as no Mars mission ever has. Astrobiology Magazine -- Planetary exploration proceeds by steps. Because life on Earth requires liquid water, the MER mission aimed to search for signs that liquid water existed on Mars in...
