Bacteriophage nuclease

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 …

Med-tricorder

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 …

Oxy-acetylene blowtorch

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 …
