Food bacteria: Mass spectrometry and FTIR spectroscopy compared

Date: Oct 1, 2014

Author: Steve Down

Scientists in Germany have compared MALDI mass spectrometry with FTIR spectroscopy for the routine identification of food-related bacteria, both techniques having particular advantages.

Biomarker background for joint diseases: Synovial fluid proteome of healthy knees

Date: Oct 1, 2014

Author: Steve Down

The proteome of synovial fluid from healthy porcine knee joints has been characterised as a model for human joints to create a reference point for the identification of biomarkers in joint diseases like arthritis.

Solar power: An organic tin approach

Date: Oct 1, 2014

Author: David Bradley

German researchers have successfully integrated an organic tin moiety into a semiconducting polymer for the first time to make a new class of solar energy absorption material that can absorb a broad band across the electromagnetic spectrum from the sun.

Diamond: Hanging by a nanothread

Date: Oct 1, 2014

Author: David Bradley

For the first time, scientists have made ultra-thin 'diamond nanothreads' with a unique structure that could be stiffer and stronger than known polymers and nanotubes. The team used a range of techniques including Raman spectroscopy, X-ray and neutron diffraction, nuclear magnetic resonance spectroscopy, transmission electron microscopy and first-principle calculations to analyse and characterise the materials

Tackling Tourette syndrome: Therapeutic clues from MRI

Date: Oct 1, 2014

Author: David Bradley

Magnetic resonance imaging scans can show the patterns of neurotransmitters in people with Tourette syndrome that are associated with particular brain activity. The details could lead to new therapeutic targets for disorder.

Dynamic sugars: Sweet approach to behaviour

Date: Oct 1, 2014

Author: David Bradley

The dynamic behaviour of complicated sugar chains in solution has been followed at atomic resolution using a combination of a sophisticated nuclear magnetic resonance spectroscopic technique and a novel molecular dynamics simulation technique.

Cancer detector: Graphene solution

Date: Oct 1, 2014

Author: David Bradley

Researchers have used X-ray photoelectron spectroscopy and Raman spectroscopy to confirm that bioreceptor molecules attached to a graphene biosensor exposed to cancer biomarkers can reveal the presence of these markers and so might be used as a cancer detector.

Gas: Of the organic interstellar kind

Date: Oct 1, 2014

Author: David Bradley

A carbon-based molecule that is not the usual fodder of interstellar dust has been detected in a giant gas cloud some 27000 light years from earth. The discovery offers a new hint as to the origins of the complex organic molecules that were the building blocks of life in our planet's primordial soup.

Journal Highlight: Interrelations of muscle functional MRI, diffusion-weighted MRI and 31P-MRS in exercised lower back muscles

Date: Sep 22, 2014

Author: spectroscopyNOW

Exercise-induced changes of transverse proton relaxation time, tissue perfusion and metabolic turnover were investigated in the lower back muscles of volunteers by applying muscle functional MRI and diffusion-weighted imaging before and after exercise as well as dynamic 31P-MRS during exercise.

Journal Highlight: Response to cold acclimation in diapause pupae of Hyles euphorbiae (Lepidoptera: Sphingidae): candidate biomarker identification using proteomics

Date: Sep 22, 2014

Author: spectroscopyNOW

Candidate protein biomarkers and biological processes that are associated with cold acclimation of overwintering Hyles euphorbiae diapause pupae have been identified to help explore intraspecific patterns of local adaptation to different climates.
