The eyes of sheep infected with scrapie—a neurological disorder similar to mad cow disease—return an intense, almost-white glow when they're illuminated with blue excitation light, according to a research project led by Iowa State University's Jacob Petrich.
Producing tightly focused beams of high energy X-rays, to examine everything from molecular structures to the integrity of aircraft wings, could become simpler and cheaper according to new research.
The DASp seeks nominations for the 2011 Bunsen-Kirchhoff Award for Analytical Spectroscopy to honour preferably the work of young scientists from universities, research institutes or industry who made excellent contributions to analytical spectroscopy.
One of the main techniques for measuring and monitoring mental activity, functional near infrared spectroscopy (fNIRS), can often be impaired because a person’s hair gets in the way. A team of researchers at the University of Texas at Dallas and the University of Texas at Arlington have developed a “brush optrode”, which provides increased sensitivity with fibre tips designed to thread through hair to enhance scalp contact.
Professor Robin Clark CNZM FRS, Sir William Ramsay Professor Emeritus, UCL, gave the University of Canterbury's premier biennial lecture, the Rutherford Lecture, in the Town Hall, Christchurch, New Zealand, on “Raman's legacy: Spectroscopy in the Cause of Art and Archaeology” on 29 September 2010.
Scientists at JILA (a joint operation of the National Institute of Standards and Technology and the University of Colorado at Boulder) and collaborators have demonstrated an improved laser-based "molecular fingerprinting" technique that picks out traces of key hydrogen-containing and other molecules from a billion other particles in a gas in just 30 seconds or less—performance suitable for breathalysers for diagnosing disease, measuring trace gases in the atmosphere, detecting security threats and other applications.
A paper by researchers at the National Institute of Standards and Technology (NIST) may breathe new life into the use of a powerful—but tricky—diagnostic technique for cell biology. The paper in the Biophysical Journal, demonstrates that with improved hardware and better signal processing, an enhancement to Raman spectroscopy, broadband coherent anti-Stokes Raman scattering (B-CARS), can quickly deliver detailed molecular maps of the contents of cells without damaging them. Earlier studies have suggested that to be useful, the technique would need power levels too high for cells.
Biomedical engineers are developing a hand-held device called a SpectroPen that could help surgeons see the edges of tumours in human patients in real time during surgery. Statistics indicate that complete removal, or resection, is the single most important predictor of patient survival for most solid tumours.
CSIRO scientists have developed a new technique using a hand-held FT-IR spectrometer for the rapid on-site detection and quantification of petroleum hydrocarbons (commonly derived from crude oil) in soil, silt, sediment or rock.
Through a combination of remote instrumentation, JPEG-style image compression algorithms and other key enhancements, Alexander Pines and members of his research group have been able to use Nuclear Magnetic Resonance (NMR) spectroscopy and Magnetic Resonance Imaging (MRI) to image materials flowing through microfluidic “lab-on-a-chip” devices and zoom in on microscopic objects of particular interest with unprecedented spatial and time resolutions.
