Monitoring bone fracture healing: Protein signals

Date: Dec 1, 2017

Author: Steve Down

Scientists in the USA have uncovered a suite of proteins in serum that might be able to follow the progression of fracture healing and lead to the development of treatments to accelerate the process.

Topological motions: Ultra-violet probe

Date: Dec 1, 2017

Author: David Bradley

European scientists have finally resolved a seeming paradox in the conflicting data from ultraviolet studies and magnetotransport examination of topological insulators. The explanation could open up this intriguing group of compounds to new electronics applications and quantum devices.

In utero cannabis exposure: Umbilical cord assessment

Date: Dec 1, 2017

Author: Steve Down

An international team of scientists has developed a way to measure cannabis in the umbilical cord, allowing clinicians to assess the risks to newborns without relying on the word of their mothers.

Box–Behnken design makes rhubarb extracts fine

Date: Dec 1, 2017

Author: Ryan De Vooght-Johnson

Medicinal rhubarb has long being used in traditional Chinese medicine, but accurate assays of its many active compounds are hampered by the expense of analytical standards. Scientists from Tianjin University and Tianjin University of Traditional Chinese Medicine have developed a new methods of assaying multiple rhubarb compounds by quantitative analysis of multi-components with a single marker (QAMS), while also optimising their extraction with a Box–Behnken design.

EEG and MRI combined: Helping solve ALS

Date: Dec 1, 2017

Author: David Bradley

Combining EEG (electroencephalography) with magnetic resonance imaging (MRI) has led to new insights into the signalling problems that lead to the delibating symptoms of amyotrophic lateral sclerosis (ALS).

Germanium-tin nanoparticles: Correlated with Raman spectroscopy

Date: Dec 1, 2017

Author: David Bradley

Raman and photoluminescence spectroscopies have been used to quantify lattice strain and photoluminescence behaviour in tin nanoparticles. The investigation reveals a correlation between the amount of tin in the nanoparticle core and how well the core's lattice matched that of its cadmium sulfide outer shell.

Antibiotic binding: X-rays show us the sites

Date: Dec 1, 2017

Author: David Bradley

Researchers at the Université de Montréal, Canada, are using X-ray crystallography to find the exact binding site for small molecules that can attach and thus inhibit the bacterial protein, TraE, which is an essential component of the plasmid transfer machinery of bacterial resistance gene sharing.

Heat stack: Infra-red tracked in real-time

Date: Dec 1, 2017

Author: David Bradley

Researchers at the Institute of Photonic Sciences in Barcelona, Spain, have tracked infrared energy in real-time as it flows through van der Waals stacks consisting of graphene encapsulated by the dielectric two-dimensional material hexagonal boron nitride (hBN).

Fluorine pharma: Quality control by NMR

Date: Dec 1, 2017

Author: David Bradley

Routine analysis and quality control of fluorine-containing pharmaceuticals could now be possible with the application of the relatively simple and straightforward technique of fluorine-19 nuclear magnetic resonance (NMR) spectroscopy, according to researchers in Kenya and Germany.

Journal Highlight: Winds in the middle cloud deck from the near-IR imaging by the Venus monitoring camera onboard Venus Express

Date: Nov 27, 2017

Author: spectroscopyNOW

The correlation approach has been applied to sequences of the near-IR images at 965 nm taken of the Venus cloud layer from the Venus Express orbiter to track cloud features and determine the wind field in the middle and lower cloud (49–57 km).
