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.

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.

Journal Highlight: Color-based automatic detection of worn out varnishes on Stradivari's "Scotland University" violin back plate

Date: May 9, 2016

Author: spectroscopyNOW

A novel program was used to analyse peculiar color hues related to wear in UV-induced fluorescence photographic images on Stradivari's "Scotland University" violin (1734) held in the "Museo del Violino" in Cremona.

Photonics: Shed a little light

Date: May 1, 2016

Author: David Bradley

Photonics can be an opaque field of endeavour. Now, new research could lend a little transparency to the science by shedding light an alternative approach to applications.

Journal Highlight: Binding of caffeine with caffeic acid and chlorogenic acid using fluorescence quenching, UV/vis and FTIR spectroscopic techniques

Date: Apr 11, 2016

Author: spectroscopyNOW

Fluorescence quenching between caffeine and chlorogenic and caffeic acids can be rationalized in terms of static quenching or the formation of non-fluorescent complexes.

Bacteria all aglow: Fluorescent carboxysomes

Date: Apr 1, 2016

Author: David Bradley

Fluorescent studies have revealed how cyanobacteria use internal molecular machines known as carboxysomes to boost their ability to convert carbon dioxide into sugar during photosynthesis. The insight couldbe exploited in nanotechnology and biomass production.

Journal Highlight: In vivo fluorescence correlation spectroscopy analyses of FMBP-1, a silkworm transcription factor

Date: Mar 7, 2016

Author: spectroscopyNOW

Fluorescence correlation spectroscopy has been used to analyze the diffusion properties of an enhanced green fluorescent protein-tagged FMBP-1 protein expressed in posterior silk gland cells of Bombyx mori at the same developmental stage as natural FMBP-1 expression.

Reflecting on the prostate: Cancer margins

Date: Mar 1, 2016

Author: David Bradley

Light reflectance spectroscopy can be used to differentiate between malignant and benign prostatic tissue with 85 percent accuracy, according to US researchers. The finding might be used in real-time tissue analysis to guide the surgeon during prostate cancer.
