Study of nature's machinery takes center stage at UH
... an 800 megahertz nuclear magnetic resonance (NMR) spectrometer was delivered to UH in January. On May 16 and 17, top experts in the field of biomolecular NMR will gather at UH to dedicate the machine and participate in a special symposium devoted to protein science.
