Using functional magnetic resonance imaging, researchers observe how cocaine-like drug disrupts neural activity in rats.
Using an advanced technique, scientists discover that one of the most common substances in our everyday lives — glass — is more complex than we thought.
13C NMR when used in metabolomics 1. Provides better peak list for database matching and spectral annotation, 2. Provides better group separation and loadings annotation when using multivariate statistical analysis, and 3. Prevents possible misidentification of metabolites.
Ten years ago the 900 Ultra-Wide Bore magnet became available to an international user community for Nuclear Magnetic Resonance spectroscopy and Magnetic Resonance Imaging at the National High Magnetic Field Lab. Since then 69 publications have been published from this instrument spanning many disciplines and the number of publications per year continues to increase with 26 in just the past 18 months demonstrating that state of the art data continues to be collected on this superb magnet.
Research sheds important light on the fundamental process of cell division.
With the help of the world's strongest MRI machine, a scientist uses a novel technique to pinpoint ground zero for a migraine.
Dynamic nuclear polarization (DNP) coupled with solid state NMR can provide orders of magnitude enhancement to normally weak NMR signals, thereby enabling the study of inherently dilute proteins such as membrane proteins. Here we demonstrate a new approach to obtain DNP signal enhancements of membrane proteins by utilizing spin labeled lipids as the polarization agents. This strategy results in more than 2x in signal enhancements of a membrane protein when compared to standard DNP sample preparation techniques.
This week at the lab, Patricia Medeiros is fishing for answers using one of the lab’s ion cyclotron resonance (ICR) magnets.
Medeiros (pictured above, standing at right, with her grad students), an assistant professor of marine organic geochemistry at the University of Georgia (UGA), arrived Monday morning with one colleague, two graduate students, dozens of water samples from estuaries around Georgia’s Sapelo Island, and lots of questions. The team will spend the week analyzing the molecular composition of the dissolved organic matter (DOM) in the water, using the ICR Facility’s 9.4 tesla passively shielded magnet.
In collaboration with UGA microbiologist Mary Ann Moran, Medeiros is studying what different communities of bacteria are doing with this DOM. They are particularly interested in how bacteria chemically transform carbon from the ocean, a key step in the marine carbon cycle that is still not well understood.
That knowledge could help us understand and better prepare for future changes in the climate, said Medeiros. "We don’t know too much about how microbes interact with DOM. We do know that DOM plays an important role in the global carbon cycle, however."

A new non-Brownian model of anomalous translational diffusion in nervous tissue is introduced and applied to the brain. This model provides new fractional order parameters of diffusion, entropy, waiting time and jump length that represent unique markers of morphology in neural tissue.
