Protein secondary structure analysis of dried blood serum using infrared spectroscopy to identify markers for colitis screening. Journal of Biophotonics, 2017; e201700057 DOI: 10.1002/jbio.201700057

A fast, simple blood test for ulcerative colitis using infrared spectroscopy could provide a cheaper, less invasive alternative for screening compared to colonoscopy, which is now the predominant test, according to a study between the Department of Physics and Astronomy and the Institute for Biomedical Sciences at Georgia State University...

This illustration shows a promising new technique for locating water on the Moon. Galactic cosmic rays (GCR) that penetrate the lunar surface, when encountering a layer with material containing hydrogen atoms (like water), trigger the ejection of protons (red spheres) that can be detected by the appropriate instrumentation in an orbiting satellite.

Prior to Apollo missions to the moon, scientists speculated that volatiles – including water – may have accumulated in permanently shaded regions at the poles. Then the Apollo era brought the return of lunar samples, enabling real measurements: They found none of the water-bearing minerals common on Earth. Over the past 10 years, however, several developments have reinvigorated the discussion...
