Journal Highlight: Quantification of DNA in simple eukaryotic cells using Fourier transform infrared spectroscopy

Date: Nov 4, 2013

Author: spectroscopyNOW

DNA/hemoglobin standards have been used to successfully estimate the DNA content in avian erythrocyte nuclei and intact erythrocytes by FTIR spectroscopy.

Far, far away: A galaxy

Date: Nov 1, 2013

Author: David Bradley

Near infra-red has revealed the presence of the most distant galaxy to US astronomers. The light from the galaxy set off on its outward journey a mere 700 million years after the Big Bang, when the universe was just 5 percent of its current age of approximately 13.8 billion years.

Fat: It's an infrared issue

Date: Oct 1, 2013

Author: David Bradley

A near-infrared fluorescence imaging probe that binds to brown adipose vasculature and emits skin-penetrating fluorescence that can be picked up from the outside by a highly sensitive camera can be used to distinguish between "good" and "bad" adipose (fat) tissue.

Journal Highlight: Optimization of lipid production for algal biodiesel in nitrogen stressed cells of Dunaliella salina using FTIR analysis

Date: Sep 30, 2013

Author: spectroscopyNOW

A study of the rates of growth and lipid accumulation in Dunaliella salina showed that the trade-off between lipid content, growth rate and cell density needs to be considered for optimisation of lipid productivity for biodiesel.

Journal Highlight: Simultaneously probing two ultrafast condensed-phase molecular symmetry breaking events by two-dimensional infrared spectroscopy

Date: Sep 2, 2013

Author: spectroscopyNOW

Direct evidence is presented for two types of solvent-mediated symmetry-breaking events that coexist on the picosecond timescale in a highly symmetric anion in a condensed phase, using 2D IR spectroscopy.

Pale blue dot: Poring over IR data

Date: Sep 1, 2013

Author: David Bradley

In the wake of the NASA Cassini mission turning its cameras towards Earth instead of its usually target the planet Saturn, its rings and moons, astronomers are now analyzing an abundance of infrared and ultraviolet data from the images.

Journal Highlight: Refining the interpretation of near-infrared band shapes in a polyynediyl molecular wire

Date: Aug 5, 2013

Author: spectroscopyNOW

The near-IR spectrum of a ruthenium-diyne complex, which serves as a model for the linear carbon allotrope carbyne, has been reexamined to show that the presence of rotamers is a crucial variable that may influence the appearance of the intervalence charge transfer band and the underlying electronic structure.

NIR signatures: Heart to heart

Date: Aug 1, 2013

Author: David Bradley

New imaging technology based on near infrared spectroscopy (NIRS) has been used by researchers at Spectrum Health's Frederik Meijer Heart & Vascular Institute to investigate patients in treatment following a heart attack.

Journal Highlight: Use of near-infrared spectroscopy to identify trends in regional cerebral oxygen saturation in horses

Date: Jul 2, 2013

Author: spectroscopyNOW

Near-infrared spectroscopy was used to identify trends in regional cerebral oxygen saturation in horses and establish a correlation between rSO2 and venous oxygen tensions.

Satisfying your curiosity: The bigger picture

Date: Jul 1, 2013

Author: David Bradley

Images recorded by NASA's Curiosity Mars rover and sent back to Earth have been composited into what is the equivalent of a 1000 megapixel photograph of the surface of the Red Planet.
