Jumping on the NMR Pulse Train
A new polarization transfer technique promises improved sensitivity and rapid analysis times.

Nobody has the time or inclination to wait over a century for nuclear magnetic resonance (NMR) results. In the past, such a delay would understandably have hampered analysis of complex structures – but now, Kong Ooi Tan, a postdoctoral researcher at the Massachusetts Institute of Technology (MIT), and his colleagues have developed a novel way of improving the sensitivity of NMR spectroscopy to massively reduce the time needed to study the structures of intricate molecules (1). Using the new approach, scientists should be able to analyze complicated molecular structures, such as that of the amyloid beta (Aβ) protein linked to Alzheimer’s disease, in just one day – a fantastic improvement over the 110 years previous techniques would have required.
