rssGoing wild: Pesticide screening method for poisoned wildlife and pets
Date: Dec 16, 2012
Author: Steve Down
Suspected poisoning of wildlife, pets and livestock can be rapidly assessed by a new multi-residue LC/MS/MS method for pesticides developed by Scottish government chemists.
Read MoreOccupational asthma markers: Candidate proteins for exposure to toluene diisocyanate
Date: Dec 16, 2012
Author: Steve Down
Scientists in Belgium have identified a series of proteins that might act as biomarkers of human exposure to the industrial chemical toluene diisocyanate, which can cause occupational asthma.
Read MoreSounding out engine efficiency: Ultrasound scan
Date: Dec 15, 2012
Author:
Atomic absorption spectroscopy might be used to analyse the metallic content of engine residues but researchers in the UK have now turned to ultrasound to scan engine components with a view to facilitating the design of new components that are more efficient and generate lower carbon emissions.
Read MoreTight fit: Loose fit
Date: Dec 15, 2012
Author:
Advanced NMR techniques have allowed a US team to map the molecular chaperone Hsp70 in different states looking at individual amino acids within the protein as they respond to different sample conditions.
Read MoreNew type of water found: It's in the mix
Date: Dec 15, 2012
Author:
Raman scattering and multivariate curve resolution allows an unprecedented signal-to-noise ratio of 10,000-to-1 in a study that reveals a previously unknown structure lying between liquid water and its vapour when oil is present.
Read MoreDiffract and destroy: 3D sleeping sickness enzyme
Date: Dec 12, 2012
Author:
The X-ray structure of an enzyme crucial to the life cycle of the microbial parasite that causes African trypanosomiasis (sleeping sickness) in humans has been determined through an international collaboration.
Read MoreJournal Highlight: Implementation of proton transfer reaction-mass spectrometry (PTR-MS) for advanced bioprocess monitoring
Date: Dec 10, 2012
Author: spectroscopyNOW
The implementation of PTR-MS technology for on-line monitoring of volatile organic compounds in the off-gas of bioreactors is described, including the development of an interface between the bioreactor and an analyzer for continuous sampling.
Read MoreJournal Highlight: X-ray-induced photo-chemistry and X-ray absorption spectroscopy of biological samples
Date: Dec 10, 2012
Author: spectroscopyNOW
The origins of X-ray-induced photo-chemistry in X-ray absorption spectroscopy experiments on biological samples have been reviewed.
Read MoreJournal Highlight: Two-photon fluorescent imaging of myelination in the spinal cord
Date: Dec 10, 2012
Author: spectroscopyNOW
The myelin-targeted fluorescent imaging agent Case Imaging Compound has been synthesized via an improved route and evaluated as a probe for two-photon fluorescent imaging of myelin in the spinal cord in both demyelinated and dysmyelinated models.
Read MoreAutistic alterations: Metabolic shifts in children with autism spectrum disorders
Date: Dec 3, 2012
Author: Steve Down
A metabolomics study of children with autism spectrum disorders has identified lower levels of several amino acids and antioxidants as well as an altered gut metabolism, providing a deeper knowledge of these changes.
