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.

Fold it: Origami kit simplifies testing
Date: Jul 1, 2012
Author: David Bradley
An origami-style test kit needs only a voltmeter for diagnostics rather than sophisticated instrumentation and could facilitate much simpler point-of-care and environmental analytics.

Anticancer tomatoes: UV reveals details of lycopene extract
Date: Jun 1, 2012
Author: David Bradley
UV-Vis spectroscopy and several other techniques have been used to characterise a lycopene extract from tomatoes. The extract has also been evaluated for its anticancer properties in laboratory mice.
