rssTotal emissions: Adding up all the light
Date: Jun 1, 2013
Author: David Bradley
How much light has been emitted by all the galaxies across the universe since the Big Bang? It is a fundamental question, poignant given that almost every photon ever emitted whether in the ultraviolet to far infrared wavelengths in the electromagnetic spectrum are still wending their way across the cosmos to this day with relatively few stopped in their tracks by matter.

Algorithmic Raman: Improved breast diagnostics
Date: Jun 1, 2013
Author: David Bradley
A newly developed, single-step algorithm for processing Raman spectra can reveal the presence of microcalcifications in breast tissue that are often associated with breast cancer lesions and so improve the precision of diagnosis of the disease itself at the early stages without multiple biopsies of suspicious lumps.

Handheld cancer detection: Microfluidics meets NMR
Date: Jun 1, 2013
Author: David Bradley
A handheld device first developed for cancer diagnosis has been adapted to rapidly diagnose tuberculosis (TB) and other bacterial infections. Two papers appearing in the journals Nature Communications and Nature Nanotechnology describe the portable systems that bring together microfluidics technology and NMR.

Aging enzyme: MRI reveals depressing link
Date: Jun 1, 2013
Author: David Bradley
Magnetic resonance imaging has revealed a possible protective role for the enzyme telomerase in processes associated with the development of depression in aging patients. The study investigated untreated, depressed participants and found that the size of the hippocampus, a brain structure that is critical for learning and memory, was associated with the amount of telomerase activity measured in the white blood cells.

Journal Highlight: 3T-MRI analysis of epidermis and dermis moisturizing using the T2-mapping sequence
Date: May 20, 2013
Author: spectroscopyNOW
T2-mapping in MRI has been applied to assess basal free water content of the epidermis and dermis and to search for an increase in free water content after applying a moisturizing cream.

Journal Highlight: High-spatial-resolution mapping of superhydrophobic cicada wing surface chemistry using IR microspectroscopy and IR imaging at two synchrotron beamlines
Date: May 15, 2013
Author: spectroscopyNOW
The chemical composition of the wings of the Clanger cicada (Psaltoda claripennis) were characterized using infrared (IR) microspectroscopy and IR imaging with a view to reproducing their characteristics in industrial applications.
