MRI brain scans have recently been used to calibrate and corroborate the results of a new eye-scanning technique that can diagnose multiple sclerosis symptoms in just a few minutes. The technique, optical coherence tomography (OCT), scans the layers of nerve fibres in the retina to reveal nerve damage associated with the disease. The quick test will ultimately complement more detailed MRI studies of the brain when nerve damage is found …

Science news with a spectroscopy bent from my desktop hit the virtual newsstands today over on SpectroscopyNOW.com First up, an atomic coilgun that can stop atoms in their tracks using a sequence of pulsed magnetic fields has been developed by US scientists. The device opens up the possibility of slowing and trapping atoms regardless of atomic number, which is not possible even with Nobel prize winning laser trapping science, which …

Nature’s blowtorch is an enzyme system that oxidizes toxins, drug molecules, and other noxious molecules found in the body ready for excretion. But, understanding exactly how this molecular machinery has been an ongoing research job for many years. Now, Ayyalusamy Ramamoorthy, Lucy Waskell, and Ulrich Dürr, at the University of Michigan, Ann Arbor, have turned to the powerful analytical technique of solid state NMR spectroscopy, to reveal important structural details …

In this week’s SpectroscopyNOW column, I cover a wide range of subjects with the usual hint of spectroscopy, informatics, and crystallography. First up is a study on a unique protein, MitoNEET.
The protein was previously identified as a putative site for the activity of diabetes drugs known as thiazolidinediones, or which Actos is an example. The determination of the protein’s three-dimensional crystal structure coupled with bioinformatics information demonstrates that it …

David Johnson and Robert Watson thought they had seen all there was to see in the Chesapeake Bay in almost three decades until they pulled out a crab from the way that had a male left half and a female right half. Now, that crab, acquired by Romuald Lipcius of the Virginia Institute of Marine Science at the College of William & Mary, has moved sideways into the world …

My latest science news round-up for SpectroscopyNOW.com is now live:
The problem of the core - Understanding how the bulk iron at the earth’s core is packed together and with what other lighter elements is critical to revealing the origins and evolution of the earth and precisely how it generates its magnetic field.
Fluorinated agents at the ready Intrusive biopsies for people with cancer could be sidestepped thanks to the development …

A new methodology for fibre-optic Raman mapping and FTIR imaging of secondary cancer cells, metastases, and detecting tumour cells has been developed by researchers in Germany. The technique facilitates imaging of samples thicker than 50 micrometres and could be used in detecting cancer cells, as a tool for molecular histopathology, in metabolic fingerprinting, general disease diagnostics.
Team member Christoph Krafft is currently in the Department of Materials and Natural Resources, …
