Research News from Rapid Communications in Mass Spectrometry
A previously unknown synthetic “designer” steroid has been identified as tetrahydrogestrinone (THG). Researchers working out of the UCLA Olympic Analytical Laboratory in Los Angeles synthesized and characterized the “New Chemical Entity”, and proceeded to develop a rapid and accurate urine detection test for it. Details of the research are published this week in Rapid Communications in Mass Spectrometry.
In June 2003, a spent syringe having allegedly contained an undetectable anabolic steroid was anonymously provided to the United States Anti-Doping Agency (USADA), and the contents delivered to the research team in Los Angeles. The researchers, led by Don Catlin, detected an unfamiliar substance and deduced its chemical formula. They were then able to synthesize a compound with this formula, which they named tetrahydrogestrinone (THG) and which matched the unknown substance in the syringe.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
