No diplomatic immunity: Microwave illness
Date: Sep 1, 2018
Author: David Bradley
A mysterious group of health problems to afflict North American diplomats in Cuba and China have a strong symptomatic match for the well-known effects of pulsed radiofrequency/microwave electromagnetic (RF/MW) radiation, according to research from Beatrice Golomb of the University of California San Diego School of Medicine.

Jovian ribbon: Infrared band
Date: Aug 1, 2018
Author: David Bradley
Scientists in the UK have used the NSFCam instrument at the NASA Infrared Telescope Facility to overturn an earlier theory about dark ribbon of weak hydrogen ion emissions that encircles Jupiter. The research could reshape our thinking about the giant planet's magnetic equator.

Journal Highlight: Unravelling the mystery of lunar anomalous craters using radar and infrared observations
Date: Jul 30, 2018
Author: spectroscopyNOW
The existence and spatial distribution of anomalous lunar craters having a high circular polarization ratio that have been imaged by radar and IR spectral measurements do not indicate the presence of large quantities of pure water ice in the polar regions, say researchers.

Droning on and off: Infrared mine detection
Date: Jul 1, 2018
Author: David Bradley
Cost effective and time efficient remote sensing that uses a "drone" equipped with an infrared camera can detect plastic munitions and explosives of concern such as so-called "butterfly" mines has enormous potential for clearing up lethal objects left behind after a military conflict.

Pillars of Creation: Clues to life
Date: May 1, 2018
Author: David Bradley
Scientists have mimicked the extreme conditions of deep space - cryogenic temperatures, ultrahigh vacuum, lots of ice particles covered with methane, ammonia, and carbon dioxide - and then blasted this miniature universe with low energy electrons, which are abundant in space, to see if they can generate the molecules of life, the amino acids. They used various techniques to pluck out information about of the products and suggest that Fourier transform infrared (FTIR) spectroscopy might be used to obtain...

Journal Highlight: Hydrocerussite‐related minerals and materials: structural principles, chemical variations and infrared spectroscopy
Date: Apr 30, 2018
Author: spectroscopyNOW
The general structural principles, chemical variations and IR spectra of the rapidly growing family of hydrocerussite‐related minerals and synthetic materials have been reviewed and the crystal structures of hydrocerussite from Merehead quarry, Somerset, England, and of its synthetic analogue, have been reported here for the first time.

Journal Highlight: The influence of bound water on the FTIR characteristics of starch and starch nanocrystals obtained from selected natural sources
Date: Apr 3, 2018
Author: spectroscopyNOW
Starch nanocrystals produced from natural sources like rice, ragi, wheat and sorghum have been compared by FTIR, DSC and TGA, showing that more bound water interacts with starch compared to starch nanocrystals.
