Lynmarie Thompson, chemistry and M2M, was awarded a two year, $615,000 NIH grant entitled, "Assembly and Function of Bacterial Chemotaxis Receptor Signaling Complexes.” The goal of this project is to assemble native-like functional nanoarrays of chemotaxis receptor complexes and determine how the proteins change their structure and dynamics during signaling. Understanding signaling in this system may be useful for the development of novel antibiotics targeting similar signaling systems that are widespread in bacteria.
Derek Lovley, microbiology and M2M, and his team at the University of Massachusetts Amherst, who is internationally known for having discovered electrically conducting microfilaments or “nanowires” in the bacterium Geobacter, announce in a new paper this month that they have discovered the unexpected structures in many other species, greatly broadening the research field on electrically conducting filaments. Details appear online in the International Society of Microbial Ecology Journal.
The International Union of Food Science and Technology (IUFoST) honored University of Massachusetts Amherst food scientist David Julian McClements with its 2018 Lifetime Achievement Award at a ceremony in Frankfurt, Germany, on Nov. 30, recognizing his “pre-eminence in and contributions to the field of food science and technology over his career.”
In a recent review of the scientific literature, award-winning food scientist David Julian McClements (CBD) and his colleague Hang Xiao (CBD) at the University of Massachusetts Amherst conclude that nanoparticle safety in food should be judged on a case-by-case basis, for example, depending on whether the particles are organic or inorganic, natural or engineered, as well as on the properties of the foods they are eaten with.
The Mass Spectrometry Core Facility hosted a workshop on November 28th focused on Metabolomics and Lipidomics, sponsored by Waters Corporation. This aspect of the “omics” pipeline is focused on small molecules and their metabolites and how changes in their concentrations can be used to understand changes in metabolic pathways in organisms resulting from external stimuli (e.g. drug therapy, dietary changes) or as biomarkers of disease.
