Europe is getting ready for its first unmanned visit to the surface of Mars. The first European Mars Rover on a joint mission of the American and European space agencies, NASA and ESA, will take off in 2018. The 250 kg Rover will roll over the surface of Mars at a speed of 100 m per hour. While doing so, it will inspect the surface and gather up ground and rock samples, some of them up to 2 m deep. The main goals of the so-called EXOMARS mission are to search for traces of former or present life on the earth-like planet, and to prepare for the arrival of a manned Mars landing.
A simple technique for measuring subcutaneous oxygen concentrations by NIR spectroscopy may help to identify patients at high risk of developing infections after surgery, reports a study in Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).
Research that made it to the cover of Analytical Chemistry has shown that a detection method developed by researchers at the University of Twente’s research institutes MESA+ and MIRA is even more sensitive than demonstrated earlier.
Researchers at the University of California, San Diego have revealed new details about how cannibalistic bacteria identify peers suitable for consumption. The work, which employed imaging mass spectrometry, is a first step toward a broader effort to map all signalling molecules between organisms.
Kenneth Standing and Werner Ens from the University of Manitoba have won the Manning Innovation Award, which has been recognising and encouraging innovation in Canada since 1982. The award is given to Canadians who have demonstrated recent innovative talent in developing and successfully marketing a new concept, process or procedure.
Counterfeiting of drugs is a huge industry with an annual turnover of more than €50 billion. In Africa the situation is extremely serious: half of the malaria medication sold there could be ineffective or even harmful. Researchers from Lund University, Sweden, and King’s College London, UK, have now developed a technique based on nuclear magnetic resonance (NMR) that could provide a good way to identify counterfeit drugs.
Infrared spectroscopy can detect E. coli faster than current testing methods and can cut days off investigations of outbreaks, according to a study at Purdue University, West Lafayette, IN, USA.
Magnetic Resonance Spectroscopy can distinguish between neurological diseases in patients without clear symptoms.
Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary to use other molecules as messengers. A team of physicists and chemists including Dr Gerald Mathias of Ludwig-Maximilians-Universität (LMU) in Munich and Professor Dominik Marx of the Ruhr-Universität Bochum has, for the first time, described how these messengers influence the assignment of spectral bands by infrared spectroscopy.
Scientists at the Georgia Institute of Technology, GA, USA, have attained very promising results on their initial investigations of a new test for ovarian cancer. Using a new technique involving mass spectrometry of a single drop of blood serum, the test correctly identified women with ovarian cancer in 100% of the patients tested.
Laser pulses lasting less than 150 attoseconds have been used to observe, in real time, the motion of electrons in the outermost (“valence”) shell of ionised krypton atoms. This technical achievement, reported in Nature 466(7307), 739–742, lays the groundwork for observations in more complex systems, which should allow a detailed examination of the fundamental processes underlying the making and breaking of chemical bonds.
