A new method for identifying bacteria that cause urinary tract infections (UTIs) will lead to much faster, more effective treatment as well as a reduction in costs. The procedure, described in the Journal of Medical Microbiology, could eventually be used for the identification of micro-organisms in other bodily fluids, including blood and spinal fluid. Scientists at the University Hospital Essen in Germany tested urine samples from in-house patients and were able to effectively separate...

Mass Spectrometry Rapidly Detects Staph Infections
2012-01-13 04:12:37

Researchers from the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. This new test takes advantage of unique isotopic labeling combined with specific bacteriophage amplification to rapidly identify Staphylococcus aureus. Quickly and accurately detecting infections caused by S. aureus is critical because the pathogenic bacterium causes a...

Researchers at the University of Oviedo (Spain) have come up with a way of tagging gunpowder which allows its illegal use to be detected even after it has been detonated. Based on the addition of isotopes, the technique can also be used to track and differentiate between wild fish and those from a fish farm, such as trout and salmon. A new method for tagging and identifying objects, substances and living beings has just been presented in this month's issue of the Analytical Chemistry...

Researchers Discover Mayans Used Tobacco

A recent discovery by researchers Dmitri Zagorevski, director of the Proteomics Core in the Center for Biotechnology and Interdisciplinary Studies at Rensselaer Polytechnic Institute and Jennifer Loughmiller-Newman, a doctoral candidate at the University at Albany, proves the Ancient Mayans used tobacco. The researchers studied scrapings from a two-and-a-half-inch high and wide container, made around 700 A.D., that was decorated with hieroglyphics depicting the actual contents, calling it...

This will help geologists temporally dissect Earth's history more faithfully New research by the National Physical Laboratory (NPL) and the Scottish Universities Environmental Research Centre (SUERC) will improve the accuracy of estimates of the time of geological events. The work centers on the calibration of one of the world's slowest clocks, known as the 'argon-argon clock'. The 'argon-argon clock' works by measuring the ratio of the amount of radioactive potassium in a sample of...
