Journal Highlight: Haploid differentiation in maize kernels based on fluorescence imaging

Date: Sep 6, 2016

Author: spectroscopyNOW

A new fluorescence-based method for inbred haploid differentiation in maize kernels was developed by utilizing the R1-nj colour marker in combination with fluorescence microspectroscopy and imaging.

Extreme ultraviolet: Constructing an experimental database

Date: Aug 1, 2016

Author: David Bradley

The identification of new emission lines from heavy ions is allowing researchers in Japan to build a database of extreme ultraviolet spectra. The data could find use in the development of extreme ultraviolet lithography light sources and other plasma applications.

Blind wine testing: Anthocyanin database enables identification in the laboratory

Date: Jul 1, 2016

Author: Ryan De Vooght-Johnson

See, sniff, sip, swirl. That's how wine connoisseurs are schooled to judge a prize-winning wine, but researchers envisage more scientific criteria. Published in Rapid Communications in Mass Spectrometry, scientists from China and New Zealand worked together to devise a method and complementary database that enable the identification of a vast array of anthocyanins not possible hitherto.

UV or not UV: Nilotinib monitoring becomes affordable and accessible

Date: Jul 1, 2016

Author: Ryan De Vooght-Johnson

Levels of therapeutic drugs, much like our caffeine fixes, constantly peak and dip as newly administered drug is both absorbed and broken down. What’s more, the level of circulating leukaemia-fighting tyrosine kinase inhibitors at its lowest—its trough—correlates strongly with its effectiveness, scientists have found. Accordingly, the monitoring of drug levels some time after administration aids clinicians in fine tuning their molecular armamentarium.

Ancient oxygen: ALMA detects distant gas

Date: Jul 1, 2016

Author: David Bradley

Oxygen, glowing because it is bathed in ultraviolet radiation has been detected in a galaxy that existed 700 million years after the Big Bang and whose light has been detected by ALMA, the Atacama Large Millimeter/submillimeter Array.

Rational drug design: structure dictates function in amide derivatives

Date: Jun 15, 2016

Author: Ryan De Vooght-Johnson

Amide derivatives can be anti-bacterials, insecticides, painkillers and antidepressants, depending on the interactions they form in the body. This study investigated the influence of their structure on these interactions using a range of multivariate methods, including principal component analysis.

Journal Highlight: Is color-specific photoswitching in dual-color fluorescence systems possible? Manipulating intermolecular energy transfer among two different fluorophores and one photoswitch

Date: Jun 6, 2016

Author: spectroscopyNOW

A rationally designed color-specific photoswitching system composed of two excited-state intramolecular proton transfer fluorophores and a color-specific photoswitchable diarylethene in PMMA film is reported.
