NMR gets the needle: Bacterial target pinpointed
Date: Jun 1, 2012
Author: David Bradley
The structure of a "needle" used by various bacteria, among them strains that cause bubonic plague, enterohaemorrhagic colitis, typhoid fever, Shigella dysentery and cholera, to get into host cells has been obtained at atomic resolution using NMR and other techniques. The research could ultimately lead to the development of novel drug to combat these and other diseases.

Nerve block: Halting pain at a snail's pace
Date: Apr 30, 2012
Author: David Bradley
Conotoxins from the predatory cone snail work even at very low levels to block nerve signals. A new NMR spectroscopic study has investigated the structures of a specific conotoxin with a view to developing these compounds, or their derivatives, as novel painkillers.

Fold it: Solid-state NMR unravels proteins
Date: Apr 1, 2012
Author: David Bradley
Researchers have developed a novel solid-state NMR spectroscopic method that uses paramagnetic tags to help them visualize the shape of protein molecules. The technique could be used to help scientists understand the properties of various biological molecules under normal, healthy conditions and also in those that are involved in a range of diseases.
