This finding demonstrates a path forward to dramatically enhance sensitivity for molecule concentration measurement by magnetic resonance using Overhauser DNP.
Three variants of the coral species A cervicornis were found to have unique metabolic signatures that can be distinguished by NMR spectroscopy. Differing levels of the metabolite trimethylamine-N-oxide, an important compound that protects against nitrogen overload, can distinguish the three variants studied. Understanding how species vary metabolically, and how that translates to species survival in stressed environments, may help us to establish desirable traits that could help with restoration and other interventions.
A new pH sensitive contrast agent for MR imaging has been developed that produces image contrast based on the local pH and that has great potential for use in living animals and medical diagnostics.
Scientists have discovered and characterized an unusual, complex natural product produced in worms, a finding that suggests a whole body of discoveries awaits.
Scientists analyzing maize affected by southern leaf blight determine the molecular structures of so-called “death acids.”
