Diamonds are for NMR: Cutting costs

Date: Jun 1, 2018

Author: David Bradley

 Diamonds are relatively inexpensive when compared to making and sustaining superconducting magnets. As such, new research offers the possibility of a very-low-cost alternative to multimillion-dollar magnetic resonance imaging (MRI) equipment and the costly nuclear magnetic resonance spectrometers used in drug discovery and other areas by using the former to preclude the need for the latter.

Label free: Infrared cancer diagnosis

Date: Jun 1, 2018

Author: David Bradley

Early diagnosis of colorectal cancer offers the best prognosis. Now, a label-free method based on mid-infrared microscopy has been developed for rapid diagnosis of this prevalent form of cancer.

Journal Highlight: Functional MRI technologies in the study of medication treatment effect on Alzheimer's disease

Date: May 21, 2018

Author: spectroscopyNOW

Current findings and the future role of functional MRI modalities for studying the treatment effects of various medications on Alzheimer's disease and mild cognitive impairment have been reviewed, focusing on medications that have been approved by FDA rather than new drugs undergoing trials.

Journal Highlight: Proteomic analysis of exosomes and Its application in HIV‐1 infection

Date: May 21, 2018

Author: spectroscopyNOW

This review focuses on exosome isolation and purification methods and their implications in HIV‐1 studies as well as the roles of proteomic techniques in defining exosomal contents and the research and clinical applications of proteomics and exosome in HIV‐1 biology.

Sample preparation in proteomics: Method bias

Date: May 15, 2018

Author: Steve Down

A comparison of four commonly used proteomics sample preparation methods for head and neck tissues has revealed that there is no universal method, each having their own deficiencies and advantages.

Emerging perfluorinated pollutants: Mass spectrometric solution

Date: May 15, 2018

Author: Steve Down

A mass spectrometric method has been developed for measuring perfluoroether carboxylic acids in water that can be applied to exposure monitoring of fluorinated industrial contaminants.

Throwing shapes: Diffracting on memory effect

Date: May 15, 2018

Author:

Shape-shifting, porous materials are one step closer thanks to work carried out at Kyoto University, Japan. X-ray crystallography studies provide the details of the function known as shape-memory effect in these substances.

Time team: NMR finds crystal

Date: May 15, 2018

Author:

Nuclear magnetic resonance (NMR) spectroscopy has been involved in uncovering hints of a time crystal, a form of matter that "ticks" when exposed to an electromagnetic pulse. The time crystal was found in the most unlikely of places: a crystal garden kit.

Power up: New lasers for spectroscopy

Date: May 15, 2018

Author:

Researchers in the USA have demonstrated a terahertz semiconductor laser with record-breaking output power that could be useful in various forms of spectroscopy and other applications.

Tail end: Bioinformatics braking proteins

Date: May 15, 2018

Author:

Informatics can identify "hotspots" of post-translational modification (PTM) activity on proteins, which has led researchers to a previously unknown mechanism that puts the brakes on an important cell signalling process involving the G proteins found in almost all living things.
