Informatics securely separates snow lotus species

Date: Oct 1, 2017

Author: Ryan De Vooght-Johnson

The snow lotus is a plant used in traditional Chinese medicine, but there has long been confusion between the three different Saussurea species called by this name. Researchers from Hong Kong Baptist University, the Chinese University of Hong Kong and the Sichuan Academy of Chinese Medical Sciences used UHPLC-MS together with principal component analysis (PCA) and hierarchical cluster analysis (HCA) to distinguish between the three species on the basis of their typical chemical composition.

Cryo-electron microscopy: Alzheimer's fibrils

Date: Oct 1, 2017

Author: David Bradley

A technique that can augment X-ray crystallographic and spectroscopic studies has been demonstrated to provide an atomic resolution in imaging of the amyloid fibrils present in Alzheimer's disease, thanks to European research.

Breaking Coloumb's law: Scattered X-ray results

Date: Oct 1, 2017

Author: David Bradley

X-ray scattering studies have been used to show how the previously immutable Coloumb's law that says electrical charges attract might be broken. The discovery could pave way the way to a new type of battery, new water treatment technology, and alternative energy supply.

Curious about Mars: Rover Raman

Date: Oct 1, 2017

Author: David Bradley

NASA's Curiosity rover has roamed the surface of Mars for the last five years with its ChemCam laser system capturing chemical data from its surroundings. Details of a Raman instrument that will be aboard the ChemCam on the NASA Mars 2020 rover, will be reported at the OSA Laser Congress, 1-5 October 2017 in Nagoya, Japan.

Pregnant pause: MRI looks at fetal heart formation

Date: Oct 1, 2017

Author: David Bradley

A new magnetic resonance imaging (MRI) study reveals that the major structures of a baby's heart form in just four days, according to scientists at the University of Leeds, UK.

Environmental, healthcare sensor: Thiourea testing

Date: Oct 1, 2017

Author: David Bradley

Co-doped manganese oxide nanoparticles (CMOs) can be made with a facile hydrothermal method and used in an emzyme-free, yet highly sensitive thiourea sensor. A whole raft of analytical techniques, including ultraviolet-visible (UV-Vis) spectroscopy, was used to characterize the particles.

Journal Highlight: Disturbing the balance: effect of contact lens use on the ocular proteome and microbiome

Date: Sep 25, 2017

Author: spectroscopyNOW

Following a discussion of defence mechanisms in the normal eye, the influence of contact lenses on the ocular microbiome and proteome has been reviewed.

Journal Highlight: Quantitative analysis of total hydrocarbons and water in oil-contaminated soils with attenuated total reflection infrared spectroscopy

Date: Sep 18, 2017

Author: spectroscopyNOW

The feasibility of direct quantitative analysis of total hydrocarbons and water in oil-contaminated soils using ATR-mid-IR spectroscopy has been evaluated, the spectral data being used to build calibration models for hydrocarbon contamination and moisture content.
