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 …

A Natural Blowtorch

Posted in Chemistry, spectroscopy at 3:30 pm by David Bradley -- Click to comment

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 …

Mighty Neat Diabetes Target

Posted in Science, spectroscopy at 2:00 pm by David Bradley -- Click to comment

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 …
