Anthrax killer: It's sedimentary

Date: Jul 15, 2013

Author: David Bradley

X-ray crystallography and other techniques have been used to study an unusual antibiotic from a marine actinomycete that has demonstrable efficacy against the lethal microbe anthrax.

Magnetic insights: Playing the percentages

Date: Jul 15, 2013

Author: David Bradley

An international research team has shown that one-dimensional molecular conducting wires can be switched to an insulating state using a weak magnetic field even at room temperature. The finding might offer new insights into the innate navigation systems of migratory birds as well as leading to new technology for magnetic field sensors, inexpensive touch screen displays and high-density magnetic storage for smartphones and other portable devices.

Fluid findings: Smoke gets in your lungs

Date: Jul 15, 2013

Author: David Bradley

A multivariate analysis of data on the chemical composition of exhaled particles in the breath of smokers and non-smokers reflects another factor in how smoking can be detrimental to lung function by revealing the shift in composition of respiratory tract lining fluid.

Journal Highlight: Towards first principles calculation of electron impact mass spectra of molecules

Date: Jul 8, 2013

Author: spectroscopyNOW

The routine calculation of EI mass spectra is based on a combination of fast quantum chemical methods, molecular dynamics, and the stochastic preparation of "hot" primary ions.

Journal Highlight: Influence of the antiscatter grid on dose and image quality in pediatric interventional cardiology X-ray systems

Date: Jul 8, 2013

Author: spectroscopyNOW

A methodology and experimental results are presented to assess the influence, in terms of dose and image quality, of the antiscatter grid in a pediatric cardiology X-ray system.

Tissue repair: Antioxidant influences processes in rainbow trout

Date: Jul 3, 2013

Author: Steve Down

The proteins involved in tissue damage and repair in the rainbow trout have been identified as an example of a lower vertebrate used in food production, those fish fed on the antioxidant astaxanthin having a different cellular response.

New use for old spice: Curcumin as MALDI imaging matrix

Date: Jul 2, 2013

Author: Steve Down

Curcumin, the spice normally used in cooking, has been used successfully as a matrix for MALDI imaging studies of a variety of samples, including fingermarks and tissue, performing at least as well as the classical matrix compound.

Journal Highlight: Does aluminium bind to histidine? An NMR investigation of amyloid β12 and amyloid β16 fragments

Date: Jul 2, 2013

Author: spectroscopyNOW

In an NMR study of the N-terminal amyloid peptide fragments Aβ12 and (Aβ16), non-histidine residues were found to be involved in aluminium binding.
