Food scientists have discovered a new, low-cost way of accurately predicting the antimicrobial properties of honey using spectroscopy. The new technique could provide a cheaper, more accurate and more practical method of determining the therapeutic properties in honey, benefiting beekeepers, processors and consumers.
While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life. Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules that are critical for life.
By combining experimental data from X-ray crystallography, NMR spectroscopy, cryoelectron microscopy and lipidomics, researchers have built a complete model of the outer envelope of an influenza A virion for the first time. The approach has revealed characteristics about the membrane components that may help scientists better understand how the virus survives in the wild or find new ways to combat it.
Scientists have discovered that the mineral jarosite breaks down organic compounds when it is flash-heated, this find has implications for Mars research. Jarosite is an iron sulfate and it is one of several minerals that NASA’s Curiosity Mission is searching for, as its presence could indicate ancient habitable environments, which may have once hosted life on the red planet.
The hunt for Earth-like planets around distant stars could soon become a lot easier thanks to a new technique. A team of researchers have successfully demonstrated how a solar telescope can be combined with a piece of technology that has already taken the physics world by storm— the laser frequency comb.
The February issue of Chromatography Techniques features a cover story on accelerator mass spectrometry, and other features on GC analysis in fracking locations, new USP methods, NIR spec analysis in tablet testing, and more!
Updates to the allowed limits of HPLC and GC parameters enable higher-speed analysis of USP methods than ever before.
Dual-column gas chromatography meets the needs of the environmental testing industry by providing fast, accurate separation of multiple halogenated compound classes.
Multiple gas chromatography methods are being deployed to monitor a suite of fracking-related contaminants that may be present in drinking water.
Accelerator mass spectrometry (AMS) is an analytical technique for measuring isotope ratios with high selectivity, sensitivity and precision. Initially developed more than 75 years ago by Robert Cornog and Luis Alvarez at the Univ. of California, Berkeley, there are now more than 110 AMS systems in 28 countries around the world, mostly at government and university labs, but a few at private companies as well.
As illustrated by experimental results, imaging in high-magnification mode is faster and results in more spectral and spatial detail.
Near-infrared spectroscopy reduces the amount of time and work needed to test sustained-release tablets, and ensures nondestructive, reliable analysis.
Sites where DNA is damaged may cause a molecule that slides along the DNA strand to scan for damage to slow on its patrol, delaying it long enough to recognize and initiate repair. The find suggests that the delay itself may be the key that allows the protein molecule to find its target.
A potential avenue to quantum computing currently generating quite the buzz in the high-tech industry is valleytronics, in which information is coded based on the wavelike motion of electrons moving through certain 2-D semiconductors. Now, a promising new pathway to valleytronic technology has been uncovered.
DNA testing on hundreds of bottles of store-brand herbal supplements sold as treatments for everything from memory loss to prostate trouble found that four out of five contained none of the herbs on the label. Instead, they were packed with cheap fillers such as wheat, rice, beans or houseplants.
Alzheimer's disease is difficult to spot in its early stages, has no effective treatment and no known cure. But, researchers are hopeful their work will make the most common form of dementia easier to diagnose and treat. Their research indicates that iron deficiency may play a significant part in the development of Alzheimer's.
<p>An international team of scientists has discovered the greatest absence of evolution ever reported— a type of deep-sea microorganism that appears not to have evolved over more than 2 billion years. But the researchers say that the organisms’ lack of change actually supports Charles Darwin’s theory of evolution.</p>
VICI’s newest member of the Pulsed Discharge Detector (PDD) family is also the smallest and thriftiest. The miniPDD uses about one fifth (20%) the amount of helium as the VICI?Valco D-3 and D-4 versions, giving up only a bit of sensitivity and dynamic range in return.
SPECTRO Analytical Instruments’ ARCOS high-resolution ICP/OES spectrometer features the fast and convenient selection of axial plasma or radial plasma observation in a single instrument—without any optical compromise. Designed for use in the most demanding elemental analysis applications in industry, science, and academia, the spectrometer features improved sensitivity, stability and precision, while lowering operating costs with the introduction of innovative components, unique capabilities and optimum flexibility.
Restek is now using universally recognized GHS labeling for its reference standards. GHS, or the Globally Harmonized System of Classification and Labeling of Chemicals, is a set of provisions for hazard classification and communication developed by the United Nations.
