Journal Highlight: Two-photon fluorescent imaging of myelination in the spinal cord
Date: Dec 10, 2012
Author: spectroscopyNOW
The myelin-targeted fluorescent imaging agent Case Imaging Compound has been synthesized via an improved route and evaluated as a probe for two-photon fluorescent imaging of myelin in the spinal cord in both demyelinated and dysmyelinated models.

Metal chameleon: Red, gold and green, by George!
Date: Nov 1, 2012
Author: David Bradley
Researchers in the UK have demonstrated how embossing or indenting tiny patterned features on to the surface of a piece of gold or other metals can change the way they reflect light and so allow them to make gold appear red and green instead of its familiar, lustrous yellow colour.

Journal Highlight: Macular thickness and volume of myopic eyes measured using spectral-domain optical coherence tomography
Date: Oct 8, 2012
Author: spectroscopyNOW
The macular thickness and volume of young myopic eyes were measured by spectral-domain optical coherence tomography to show that thinner macular thickness, lower macular volume and thicker foveal thickness are associated with longer axial length.

ChemCam's mega blast: Martian rock succumbs
Date: Sep 1, 2012
Author: David Bradley
The ChemCam instrument aboard NASA's Curiosity rover recorded its first spectra on Mars in mid-August, giving the systems a little target practice but also demonstrating that the device is working as it should by providing a sneak preview of rocky spectra.

Damaged goods: Probing the depths
Date: Aug 1, 2012
Author: David Bradley
Electronic devices are susceptible to damage from radiation, potentially cosmic radiation and even ultraviolet radiation. A study using coherent acoustic phonon spectroscopy (CAPS) reveals that the amount of optical damage, as opposed to structural damage, that can be caused may be more than ten times greater than studies suggested.
