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.

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.
Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...
The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
