Coupling an isotope ratio mass spectrometer to an elemental analyser or gas chromatograph/combustion system has been used to analyse squalene and squalane, oils often used in the production of cosmetics and vaccines, and can show whether they came originally from the liver oil of deepwater sharks or from olive oil.
David Wetzel and Yong-Cheng Shi of Kansas State University, USA, and John Reffner from John Jay College, City University of New York, USA have applied microscopic chemical imaging to single modified starch granules. Starch manufacturers can use this to determine if the modifying agent used in the production process is uniformly distributed across individual modified starch granules. Mark Boatwright, a K-State graduate research assistant in grain science and industry assisted with data processing for the study.
The first researchers have arrived on the latest experimental station to become operational at the Diamond Light Source, the UK’s national synchrotron facility. The new experimental station (B18) offers X-ray Absorption Spectroscopy (XAS).
Lipids produced by the aspirin target COX-2 have anti-oxidant and anti-inflammatory properties as presented in a study published online this week in Nature Chemical Biology (doi: 10.1038/nchembio.367).
The location of metal complexes within living cancer cells has been accurately determined using Raman microscopy. The researchers have thus gained new insights into the mechanism of action of metal-containing drugs, to which they ascribe great potential capacities, e.g. in the treatment of cancer. These findings are of fundamental significance and are thus featured as a VIP (very important paper) in the current edition of Angewandte Chemie.
Thermo Fisher Scientific has opened a global food testing laboratory devoted to helping contain costly and life-threatening chemical contamination crises. The Food Safety Response Center, located in Dreieich, Germany, is equipped with state-of-the-art equipment and staffed by world-class chemists who will quickly mobilise to aid governments and businesses facing an unknown food safety threat involving chemical contaminants. One recent threat, the melamine crisis in China, claimed the lives of at least six children, made nearly 300,000 ill and cost companies worldwide billions before it was contained.
The recipients of the 2010 European Magnetic Resonance Awards are John R. Griffiths (Basic Sciences) for his contributions to the applications of magnetic resonance spectroscopy in oncology, and Stefan Neubauer (Medical Sciences) for his contributions to anatomical and functional cardiovascular magnetic resonance imaging and spectroscopy.
Bruker Corporation and Agilent Technologies have announced that they have entered into a definitive asset purchase agreement. Pursuant to this agreement, Bruker will acquire certain product lines of Varian Inc., which Agilent has committed to divest in connection with obtaining regulatory approval for Agilent's previously announced acquisition of Varian.
ESA’s Herschel Space Observatory has revealed the chemical fingerprints of potential life-enabling organic molecules in the Orion Nebula, a nearby stellar nursery in our Milky Way galaxy. This detailed spectrum, obtained with the Heterodyne Instrument for the Far Infrared (HIFI) demonstrates the gold mine of information that Herschel-HIFI will provide on how organic molecules form in space.
